2.3 創(chuàng)建前端頁面

在webapp文件夾中創(chuàng)建index.jsp和login.jsp
index.jsp

</html>

2.4 配置視圖信息

application.properties

server.port=8080
server.servlet.context-path=/shiro
spring.application.name=shiro

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

2.5 解決IDEA沖突問題

JSP 與IDEA 與SpringBoot存在一定的不兼容，修改此配置即可解決

2.6 測試搭建的環(huán)境

在這里插入圖片描述

3. 整合Shiro

3.1 引入依賴

pom.xml

<!--引入shrio-->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-starter</artifactId>
    <version>1.5.3</version>
</dependency>

3.2 自定義Realm

在shiro文件夾下創(chuàng)建realm文件夾

package com.test.shiro.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

/**
 * 自定義Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        return null;
    }
}

3.3 Shiro配置

在config文件夾中創(chuàng)建ShiroConfig.java

@Configuration
public class ShiroConfig {
    //ShiroFilter過濾所有請求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //給ShiroFilter配置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //配置系統(tǒng)受限資源
        //配置系統(tǒng)公共資源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/index.jsp","authc");//表示這個資源需要認證和授權(quán)
        // 設(shè)置認證界面路徑
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //創(chuàng)建安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //創(chuàng)建自定義Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

3.4 啟動測試

輸入http://localhost:8080/shiro/index.jsp，發(fā)現(xiàn)需要跳轉(zhuǎn)到login.jsp

在這里插入圖片描述

4. 常見過濾器

注意: shiro提供和多個默認的過濾器，我們可以用這些過濾器來配置控制指定url的權(quán)限：

5. 認證和退出

5.1 在index.jsp添加a標(biāo)簽

index.jsp

<a href="${pageContext.request.contextPath}/user/logout" rel="external nofollow"  rel="external nofollow" >退出登錄</a>

5.2 編寫controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {
    @RequestMapping("logout")
    public String logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "redirect:/login.jsp";
    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //獲取主題對象
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登錄成功?。?！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("用戶錯誤！?。?);
        } catch (IncorrectCredentialsException e) {
            System.out.println("密碼錯誤?。?！");
        }
        return "redirect:/login.jsp";
    }
}

5.3 修改自定義Realm

CustomerRealm.java

/**
 * 自定義Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String principal = (String) authenticationToken.getPrincipal();
        if ("zhangsan".equals(principal)) {
            return new SimpleAuthenticationInfo(principal,"123456",this.getName());
        }
        return null;
    }
}

5.4 修改ShiroConfig配置

ShiroConfig.java
公共資源一定是在受限資源上面，不然會造成死循環(huán)。

@Configuration
public class ShiroConfig {
    //ShiroFilter過濾所有請求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //給ShiroFilter配置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //配置系統(tǒng)受限資源
        //配置系統(tǒng)公共資源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/user/login","anon");//表示這個為公共資源 一定是在受限資源上面
        map.put("/**","authc");//表示這個受限資源需要認證和授權(quán)
        // 設(shè)置認證界面路徑
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //創(chuàng)建安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //創(chuàng)建自定義Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

5.5 測試

登錄正常，登出正常，未登錄和登出后不能訪問index.jsp

在這里插入圖片描述

6. MDSalt的認證實現(xiàn)

6.1 創(chuàng)建數(shù)據(jù)庫

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for t_user
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` INT(6) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(40) DEFAULT NULL,
  `password` VARCHAR(40) DEFAULT NULL,
  `salt` VARCHAR(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

SET FOREIGN_KEY_CHECKS = 1;

6.2 引入依賴

}

6.5 創(chuàng)建DAO接口

UserDao.java

@Mapper
@Repository
public interface UserDao {
    void save(User user);

    User findByUsername(String username);
}

UserDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.test.dao.UserDao">

    <insert id="save" parameterType="User" useGeneratedKeys="true" keyProperty="id">
        insert into t_user values(#{id},#{username},#{password},#{salt})
    </insert>
    <select id="findByUsername" parameterType="String" resultType="User">
        select id,username,password,salt
        from t_user
        where username = #{username}
    </select>
</mapper>

6.7 創(chuàng)建Service接口

UserService.java

public interface UserService {
    //注冊用戶方法
    void register(User user);
    //根據(jù)用戶名查找用戶
    User findByUsername(String username);
}

6.8 編寫生成隨機鹽工具類

SaltUtil.java

public class SaltUtil {
    public static String getSalt(int n) {
        char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < n; i++) {
            char c = chars[new Random().nextInt(chars.length)];
            sb.append(c);
        }
        return sb.toString();
    }

    public static void main(String[] args) {
        System.out.println(getSalt(4));
    }
}

6.9 編寫Service實現(xiàn)類

UserServiceImpl.java

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;

    @Override
    public void register(User user) {
        //1.獲取隨機鹽
        String salt = SaltUtil.getSalt(8);
        //2.將隨機鹽保存到數(shù)據(jù)
        user.setSalt(salt);
        //3.明文密碼進行md5 + salt + hash散列
       Md5Hash MD5 = new Md5Hash(user.getPassword(),salt,1024);
       user.setPassword(MD5.toHex());
       userDao.save(user);
    }

    @Override
    public User findByUsername(String username) {
        return userDao.findByUsername(username);
    }
}

6.10 編寫Controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/register")
    public String register(User user) {
        try {
            userService.register(user);
            return "redirect:/login.jsp";
        } catch (Exception e) {
            e.printStackTrace();
            return "redirect:/register.jsp";
        }

    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //獲取主題對象
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登錄成功?。?！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("用戶錯誤?。?！");

        UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
        //System.out.println(userService);
        User user = userService.findByUsername(principal);
        if (!ObjectUtils.isEmpty(user)) {
            return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), ByteSource.Util.bytes(user.getSalt()), this.getName());
        }
        return null;

8. shiro使用緩存

8.1 Cache

8.1.1 Cache 作用

Cache 緩存: 計算機內(nèi)存中一段數(shù)據(jù)

作用: 用來減輕DB的訪問壓力,從而提高系統(tǒng)的查詢效率

流程:

在這里插入圖片描述

8.1.2 使用shiro中默認EhCache實現(xiàn)緩存

1.引入依賴

<!--引入shiro和ehcache-->
<dependency>
  <groupId>org.apache.shiro</groupId>
  <artifactId>shiro-ehcache</artifactId>
  <version>1.5.3</version>
</dependency>

2.開啟緩存

//3.創(chuàng)建自定義realm
@Bean
public Realm getRealm() {
    CustomerRealm realm = new CustomerRealm();
    HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
    //設(shè)置使用MD5加密算法
    credentialsMatcher.setHashAlgorithmName("md5");
    //散列次數(shù)
    credentialsMatcher.setHashIterations(1024);
    realm.setCredentialsMatcher(credentialsMatcher);

    //開啟緩存管理器
    realm.setCacheManager(new EhCacheManager());
    realm.setCachingEnabled(true);//開啟緩存
    realm.setAuthenticationCachingEnabled(true);//開啟認證緩存
    realm.setAuthenticationCacheName("authentication");
    realm.setAuthorizationCachingEnabled(true);//開啟授權(quán)緩存
    realm.setAuthorizationCacheName("authorization");

    return realm;
}

8.1.3 測試

注意:如果控制臺沒有任何sql展示說明緩存已經(jīng)開啟

8.2 Redis

8.2.1 shiro中使用Redis作為緩存實現(xiàn)

1.引入redis依賴

<!--redis整合springboot-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.配置redis連接

spring.redis.port=6379
spring.redis.host=localhost
spring.redis.database=0

3.啟動redis服務(wù)

在這里插入圖片描述

4. 開發(fā)RedisCacheManager

自定義shiro緩存管理器
RedisCacheManager.java

import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.apache.shiro.cache.CacheManager;

//自定義shiro緩存管理器
public class RedisCacheManager implements CacheManager {
    //參數(shù)1:認證或者是授權(quán)緩存的統(tǒng)一名稱
    @Override
    public <K, V> Cache<K, V> getCache(String cacheName) throws CacheException {
        System.out.println(cacheName);
        return new RedisCache<K,V>(cacheName);
    }
}

5.開RedisCache實現(xiàn)

//自定義redis緩存的實現(xiàn)
public class RedisCache<k,v> implements Cache<k,v> {

    private String cacheName;

    public RedisCache() {
    }

    public RedisCache(String cacheName) {
        this.cacheName = cacheName;
    }

    @Override
    public v get(k k) throws CacheException {
        return (v) getRedisTemplate().opsForHash().get(this.cacheName, k.toString());
    }

    @Override
    public v put(k k, v v) throws CacheException {
        System.out.println("put key: "+k);
        System.out.println("put value:"+v);
        getRedisTemplate().opsForHash().put(this.cacheName,k.toString(), v);
        return null;
    }

    @Override
    public v remove(k k) throws CacheException {
        System.out.println("=============remove=============");
        return (v) getRedisTemplate().opsForHash().delete(this.cacheName,k.toString());
    }

    @Override
    public void clear() throws CacheException {
        System.out.println("=============clear==============");
        getRedisTemplate().delete(this.cacheName);
    }

    @Override
    public int size() {
        return getRedisTemplate().opsForHash().size(this.cacheName).intValue();
    }

    @Override
    public Set<k> keys() {
        return getRedisTemplate().opsForHash().keys(this.cacheName);
    }

    @Override
    public Collection<v> values() {
        return getRedisTemplate().opsForHash().values(this.cacheName);
    }

    private RedisTemplate getRedisTemplate(){
        RedisTemplate redisTemplate = (RedisTemplate) ApplicationContextUtil.getBean("redisTemplate");
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

6. 啟動項目測試發(fā)現(xiàn)報錯錯誤解釋: 由于shiro中提供的simpleByteSource實現(xiàn)沒有實現(xiàn)序列化,所有在認證時出現(xiàn)錯誤信息

在這里插入圖片描述

解決方案如下：
實現(xiàn) 實體類序列化
自定義salt實現(xiàn) 實現(xiàn)序列化接口

import org.apache.shiro.codec.Base64;
import org.apache.shiro.codec.CodecSupport;
import org.apache.shiro.codec.Hex;

import java.util.Arrays;
//自定義salt實現(xiàn) 實現(xiàn)序列化接口
public class MyByteSource implements ByteSource, Serializable {
    private  byte[] bytes;
    private String cachedHex;
    private String cachedBase64;
    public MyByteSource(byte[] bytes) {
        this.bytes = bytes;
    }
    public MyByteSource(char[] chars) {
        this.bytes = CodecSupport.toBytes(chars);
    public MyByteSource(String string) {
        this.bytes = CodecSupport.toBytes(string);
    public MyByteSource(ByteSource source) {
        this.bytes = source.getBytes();
    public MyByteSource(File file) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(file);
    public MyByteSource(InputStream stream) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(stream);
    public static boolean isCompatible(Object o) {
        return o instanceof byte[] || o instanceof char[] || o instanceof String || o instanceof ByteSource || o instanceof File || o instanceof InputStream;
    public byte[] getBytes() {
        return this.bytes;
    public boolean isEmpty() {
        return this.bytes == null || this.bytes.length == 0;
    public String toHex() {
        if (this.cachedHex == null) {
            this.cachedHex = Hex.encodeToString(this.getBytes());
        }
        return this.cachedHex;
    public String toBase64() {
        if (this.cachedBase64 == null) {
            this.cachedBase64 = Base64.encodeToString(this.getBytes());
        return this.cachedBase64;
    public String toString() {
        return this.toBase64();
    public int hashCode() {
        return this.bytes != null && this.bytes.length != 0 ? Arrays.hashCode(this.bytes) : 0;
    public boolean equals(Object o) {
        if (o == this) {
            return true;
        } else if (o instanceof ByteSource) {
            ByteSource bs = (ByteSource)o;
            return Arrays.equals(this.getBytes(), bs.getBytes());
        } else {
            return false;
    private static final class BytesHelper extends CodecSupport {
        private BytesHelper() {
        public byte[] getBytes(File file) {
            return this.toBytes(file);
        public byte[] getBytes(InputStream stream) {
            return this.toBytes(stream);
}

修改自定義realm中使用的salt

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    String principal = (String) authenticationToken.getPrincipal();
    //獲取UserService對象
    UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
    //System.out.println(userService);
    User user = userService.findByUsername(principal);
    if (!ObjectUtils.isEmpty(user)) {
        return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), new MyByteSource(user.getSalt()), this.getName());
    }
    return null;
}

    請輸入驗證碼: <input type="text" name="code"><img src="${pageContext.request.contextPath}/user/getImage" alt="">

    <input type="submit" value="登錄">
</form>

9.3 開發(fā)控制器

  //生成驗證碼
  String code = VerifyCodeUtils.generateVerifyCode(4);
  //驗證碼放入session
  session.setAttribute("code",code);
  //驗證碼存入圖片
  ServletOutputStream os = response.getOutputStream();
  response.setContentType("image/png");
  VerifyCodeUtils.outputImage(220,60,os,code);
}

9.4 放行驗證碼

ShiroConfig.java

map.put("/user/getImage","anon");//驗證碼

9.5 修改認證流程

@RequestMapping("login")

    //比較驗證碼
    String codes = (String) session.getAttribute("code");
    try {
        if (codes.equalsIgnoreCase(code)){
            //獲取主體對象
            Subject subject = SecurityUtils.getSubject();
                subject.login(new UsernamePasswordToken(username, password));
                return "redirect:/index.jsp";
        }else{

        System.out.println("用戶名錯誤!");
    } catch (IncorrectCredentialsException e) {
        e.printStackTrace();
        System.out.println("密碼錯誤!");
    }catch (Exception e){
        e.printStackTrace();
        System.out.println(e.getMessage());
    }
    return "redirect:/login.jsp";
}

9.6 啟動測試

在這里插入圖片描述

10. shiro標(biāo)簽在jsp使用

需要在jsp頁面中引入標(biāo)簽
<%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro" %>
標(biāo)簽：
<shiro:authenticated> 登錄之后
<shiro:notAuthenticated> 不在登錄狀態(tài)時
<shiro:guest> 用戶在沒有RememberMe時
<shiro:user> 用戶在RememberMe時
<shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色時
<shiro:hasRole name="abc"> 擁有角色abc
<shiro:lacksRole name="abc"> 沒有角色abc
<shiro:hasPermission name="abc"> 擁有權(quán)限資源abc <shiro:lacksPermission name="abc"> 沒有abc權(quán)限資源
<shiro:principal> 顯示用戶身份名稱
<shiro:principal property="username"/> 顯示用戶身份中的屬性值

11.4 加入shiro的方言配置

頁面標(biāo)簽不起作用一定要記住加入方言處理

@Bean(name = "shiroDialect")
public ShiroDialect shiroDialect(){
  return new ShiroDialect();
}
