基于SpringBoot2的Shiro最簡配置操作(兩個文件)

更新時間：2021年01月25日 11:29:59 作者：蒼穹之躍

這篇文章主要介紹了基于SpringBoot2的Shiro最簡配置操作(兩個文件)，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

基礎環(huán)境：依賴

<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.2.1.RELEASE</version>
 <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependency>
 <groupId>org.apache.shiro</groupId>
 <artifactId>shiro-spring-boot-starter</artifactId>
 <version>1.4.0</version>
</dependency>

如果不是前后端分離，要實現(xiàn)頁面級的權限控制，則加入以下依賴就可以使用shiro的權限標簽了（記得在html頭部加上相應約束：

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="Thymeleaf" xmlns:shiro="http://www.pollix.at/thymeleaf/shiro"
  lang="en">
）：
<dependency>
 <groupId>com.github.theborakompanioni</groupId>
 <artifactId>thymeleaf-extras-shiro</artifactId>
 <version>2.0.0</version>
</dependency>

Realm：認證鑒權器

package com.rz.monomer.modules.shiro; 
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.rz.monomer.modules.user.entity.SysUserInfo;
import com.rz.monomer.modules.user.entity.SysUserRole;
import com.rz.monomer.modules.user.service.SysButtonInfoService;
import com.rz.monomer.modules.user.service.SysUserInfoService;
import com.rz.monomer.modules.user.service.SysUserRoleService;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection; 
import java.util.Set;
import java.util.stream.Collectors;
 
/**
 * 認證、鑒權類（必須）

 **/
@Slf4j
public class ShiroRealm extends AuthorizingRealm {
 //以下三個服務是普通Dao查詢，從數(shù)據(jù)庫查詢用戶及其角色權限信息（這個類沒有自動注入，需要在下個文件中手動注入）
 private SysUserInfoService userInfoService;
 private SysButtonInfoService buttonInfoService;
 private SysUserRoleService userRoleService;
 
 public ShiroRealm(SysUserInfoService userInfoService, SysButtonInfoService buttonInfoService, SysUserRoleService userRoleService) {
  this.userInfoService = userInfoService;
  this.buttonInfoService = buttonInfoService;
  this.userRoleService = userRoleService;
 }
 
 @Override
 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
  log.info("check authorization info");
 
  SimpleAuthorizationInfo authInfo = new SimpleAuthorizationInfo();
 
  // 獲取當前用戶
  SysUserInfo userInfo = (SysUserInfo) principals.getPrimaryPrincipal();
 
  // 查詢角色信息
  Set<Long> userRoles = userRoleService.list(new LambdaQueryWrapper<SysUserRole>().eq(SysUserRole::getUserId, userInfo.getId()))
            .stream()
            .map(SysUserRole::getRoleId)
            .collect(Collectors.toSet());
  //角色所有權限
  Set<String> perms = buttonInfoService.getPermsByRoles(userRoles);
  authInfo.addStringPermissions(perms);
  return authInfo;
 }
 
 @Override
 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
  log.info("check authentication info");
 
  String username = (String) token.getPrincipal();
 
  // 獲取用戶信息
  SysUserInfo user = userInfoService.getOne(new LambdaQueryWrapper<SysUserInfo>().eq(SysUserInfo::getUsername, username));
 
  if (user == null) {
   return null;
  }
 
  /*SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user, user.getPassword(),
    ByteSource.Util.bytes(654321), getName());*/
 
  SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user, user.getPassword(), getName());
  return authenticationInfo;
 }
}

WebSecurityManager：安全管理器

package com.rz.monomer.modules.shiro; 
import com.rz.monomer.modules.user.service.SysButtonInfoService;
import com.rz.monomer.modules.user.service.SysUserInfoService;
import com.rz.monomer.modules.user.service.SysUserRoleService;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;
import org.apache.shiro.web.filter.authc.LogoutFilter;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; 
import javax.servlet.Filter;
import java.util.LinkedHashMap;
import java.util.Map;
 
/**

 *
 * @author sunziwen

 **/
@Configuration
@Slf4j
@AllArgsConstructor
public class WebSecurityManager {
 private SysUserInfoService userInfoService;
 private SysButtonInfoService buttonInfoService;
 private SysUserRoleService userRoleService;
 
 /**
  * 安全管理器
  */
 @Bean
 public DefaultWebSecurityManager securityManager() {
  DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
  securityManager.setRealm(realm());
  return securityManager;
 }
 
 /**
  * 認證鑒權器（安全管理器的依賴）
  */
 @Bean
 public ShiroRealm realm() {
  return new ShiroRealm(userInfoService, buttonInfoService, userRoleService);
 }
 
 /**
  * 配置攔截規(guī)則
  */
 @Bean
 public ShiroFilterFactoryBean filter(org.apache.shiro.mgt.SecurityManager securityManager) {
  log.info("config shiro filter");
  ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
  shiroFilterFactoryBean.setSecurityManager(securityManager);
 
  // 定義URL攔截鏈
  Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
  // 允許匿名用戶訪問首頁
  filterChainDefinitionMap.put("/shiro/index", "anon");
  // 定義注銷路徑
  filterChainDefinitionMap.put("/shiro/logout", "logout");
  // 所有用戶界面都需要身份驗證，否則會跳轉到loginurl，由FormAuthenticationFilter處理
  filterChainDefinitionMap.put("/shiro/user/**", "authc");
  // 為login路徑定義攔截，由FormAuthenticationFilter處理
  filterChainDefinitionMap.put("/shiro/login", "authc");
  // 所有vip路徑要求具備vip角色權限
  filterChainDefinitionMap.put("/shiro/vip/**", "roles[vip]");
  // 指定loginurl 路徑
  shiroFilterFactoryBean.setLoginUrl("/shiro/login");
  // 登錄成功后跳轉路徑
  shiroFilterFactoryBean.setSuccessUrl("/shiro/user/");
  // for un authenticated
  shiroFilterFactoryBean.setUnauthorizedUrl("/shiro/unauth");
  shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
 
  // 自定義filters，可覆蓋默認的Filter列表，參考 DefaultFilter
  Map<String, Filter> filters = new LinkedHashMap<String, Filter>();
 
  // 定制logout 過濾，指定注銷后跳轉到登錄頁(默認為根路徑)
  LogoutFilter logoutFilter = new LogoutFilter();
  logoutFilter.setRedirectUrl("/shiro/login");
  filters.put("logout", logoutFilter);
 
  // 定制authc 過濾，指定登錄表單參數(shù)
  FormAuthenticationFilter authFilter = new FormAuthenticationFilter();
  authFilter.setUsernameParam("username");
  authFilter.setPasswordParam("password");
  filters.put("authc", authFilter);
 
  shiroFilterFactoryBean.setFilters(filters);
  return shiroFilterFactoryBean;
 }
}

Test：登錄測試

package com.rz.monomer.modules.user.controller; 
import com.rz.monomer.commons.utils.Md5Encrypt;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.annotation.RequiresAuthentication;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*; 
@RestController
@Slf4j
public class LoginController { 
 @PostMapping("/login")
 public String login(@RequestParam("username") String username, @RequestParam("password") String password) {
  Subject subject = SecurityUtils.getSubject();
  AuthenticationToken token = new UsernamePasswordToken(username, Md5Encrypt.md5(password));
 
  try {
   // 執(zhí)行登錄
   subject.login(token);
 
  } catch (UnknownAccountException e) {
 
   // 未知用戶
   log.warn("the account {} is not found", username);
 
   return "account not found";
  } catch (IncorrectCredentialsException e) {
 
   // 用戶或密碼不正確
   log.warn("the account or password is not correct");
   return "account or password not correct";
 
  }
  return "login success";
 }
 
}

補充：SpringBoot配置Shiro時踩坑

在SpringBoot2.0整合shiro時使用@EnableAutoConfiguration的時候需要對config文件進行掃描，即使用@ComponentScan對配置進行掃描。

或者直接使用@SpringBootApplication,但是這種方法會將主方法目錄下的所有package都進行掃描影響項目效率。

Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - zxc, rememberMe=false]. Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException

當出現(xiàn)此異常時，一般情況是用戶名密碼不匹配，或者是在配置對應的Realm時出現(xiàn)空值導致匹配失敗。

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。如有錯誤或未考慮完全的地方，望不吝賜教。
