springboot+springsecurity+mybatis+JWT+Redis?實(shí)現(xiàn)前后端離實(shí)戰(zhàn)教程

 更新時(shí)間：2024年01月22日 10:15:59   作者：一點(diǎn)點(diǎn)前進(jìn)的小鄭  
這篇文章主要介紹了springboot+springsecurity+mybatis+JWT+Redis?實(shí)現(xiàn)前后端離實(shí)戰(zhàn)教程,需要的朋友可以參考下

寫(xiě)在開(kāi)頭：這篇是實(shí)戰(zhàn)篇，即默認(rèn)各位看官具備相應(yīng)的基礎(chǔ)

一、springboot

1.新建項(xiàng)目

  我是用idea，jdk選擇1.8以上

 各個(gè)名字自行命名

添加部分依賴(lài)，后面再往pom.xml加入（這里忘記改了，springboot的版本我使用的是1.5.3release版本?。?/p>

簡(jiǎn)單的項(xiàng)目搭建好了，下一步

2.application.yml的配置

數(shù)據(jù)源

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost/springboot?characterEncoding=utf-8&useSSl=false
    driver-class-name: com.mysql.jdbc.Driver

數(shù)據(jù)池用了druid，pom.xml加入依賴(lài)

<!-- druid數(shù)據(jù)庫(kù)連接池 -->
<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>druid</artifactId>
   <version>1.1.8</version>
</dependency>

添加mabatis、druid，完整配置：

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost/springboot?characterEncoding=utf-8&useSSl=false
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    #監(jiān)控統(tǒng)計(jì)攔截的filters
    filters: stat,wall,log4j
    #druid配置
    #配置初始化大小/最小/最大
    initialSize: 5
    minIdle: 5
    maxActive: 20
    #獲取連接等待超時(shí)時(shí)間
    maxWait: 60000
    #間隔多久進(jìn)行一次檢測(cè)，檢測(cè)需要關(guān)閉的空閑連接
    timeBetweenEvictionRunsMillis: 60000
    #一個(gè)連接在池中最小生存的時(shí)間
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    #打開(kāi)PSCache，并指定每個(gè)連接上PSCache的大小。oracle設(shè)為true，mysql設(shè)為false。分庫(kù)分表較多推薦設(shè)置為false
    poolPreparedStatements: false
    maxPoolPreparedStatementPerConnectionSize: 20
    # 通過(guò)connectProperties屬性來(lái)打開(kāi)mergeSql功能；慢SQL記錄
    connectionProperties:
      druid:
        stat:
          mergeSql: true
          slowSqlMillis: 5000
#mybatis是獨(dú)立節(jié)點(diǎn)，需要單獨(dú)配置
mybatis:
  mapper-locations: classpath*:mapper/*.xml
  type-aliases-package: com.deceen.demo.entity
  configuration:
    map-underscore-to-camel-case: true

3.寫(xiě)一個(gè)小demo

controller層

package com.deceen.demo.controller;
import com.deceen.demo.entity.DemoEntity;
import com.deceen.demo.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
/**
 * @author: zzx
 * @date: 2018/10/25 16:48
 * @description: demo
 */
@RestController
@RequestMapping("/test")
public class DemoController {
    @Autowired
    private DemoService orderService;
    @RequestMapping("/getUser")
    public List<DemoEntity> getUser(){
        List<DemoEntity> result = orderService.getUser();
        return result;
    }
}

service層

package com.deceen.demo.service;
import com.deceen.demo.entity.DemoEntity;
import java.util.List;
/**
 * @author: zzx
 * @date: 2018/10/25 17:00
 * @description:
 */
public interface DemoService {
    List<DemoEntity> getUser();
}

impl

package com.deceen.demo.service.impl;
import com.deceen.demo.dao.DemoMapper;
import com.deceen.demo.entity.DemoEntity;
import com.deceen.demo.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
 * @author: zzx
 * @date: 2018/10/25 17:03
 * @description:
 */
@Service
public class DemoServiceImpl implements DemoService {
    @Autowired
    private DemoMapper demoMapper;
    @Override
    public List<DemoEntity> getUser() {
        return demoMapper.getUser();
    }
}

dao

package com.deceen.demo.dao;
import com.deceen.demo.entity.DemoEntity;
import org.springframework.stereotype.Component;
import java.util.List;
/**
 * @author: zzx
 * @date: 2018/10/25 17:05
 * @description:
 */
@Component
public interface DemoMapper {
    List<DemoEntity> getUser();
}

entity

package com.deceen.demo.entity;
import lombok.Data;
/**
 * @author: zzx
 * @date: 2018/10/25 17:01
 * @description:
 */
@Data
public class DemoEntity {
    private Integer id;
    private Integer age;
    private String name;
    private Float height;
}

這里介紹一下lombok，感覺(jué)蠻好用的一個(gè)插件，DemoEntity這個(gè)類(lèi)中的@Data注解就是其一，可以自動(dòng)生成getset方法（編譯的時(shí)候），后面也會(huì)用到。教程：http://www.dbjr.com.cn/article/214041.htm

mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.deceen.demo.dao.DemoMapper">
    <select id="getUser" resultType="com.deceen.demo.entity.DemoEntity">
        SELECT * FROM girl
    </select>
</mapper>

（相關(guān)的數(shù)據(jù)庫(kù)自己隨便建，跟DemoEntity字段對(duì)上就好了。。。）

訪(fǎng)問(wèn)http://localhost:8080/test/getUser

成功

二、druid

上文提到druid，其實(shí)尚未真正可以使用，下面我們繼續(xù)

1.druid參數(shù)配置

package com.deceen.common.config;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import javax.sql.DataSource;
/**
 * druid參數(shù)配置
 * @author zzx
 * @date 2018/10/15 10:09
 */
@Configuration
@PropertySource(value = "classpath:application.yml")
public class DruidConfiguration {
    /**
     * @author zzx
     * @date 2018-10-15 11:28
     * @todo 數(shù)據(jù)源配置
    */
    @Bean(destroyMethod = "close", initMethod = "init")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }
    /**
     * druid
     * 注冊(cè)一個(gè)StatViewServlet
     * @return
     */
    @Bean
    public ServletRegistrationBean druidStatViewServlet(){
        //org.springframework.boot.context.embedded.ServletRegistrationBean提供類(lèi)的進(jìn)行注冊(cè).
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //添加初始化參數(shù)：initParams
        //白名單：
        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //IP黑名單 (存在共同時(shí)，deny優(yōu)先于allow) : 如果滿(mǎn)足deny的話(huà)提示:Sorry, you are not permitted to view this page.
        //servletRegistrationBean.addInitParameter("deny","192.168.1.73");
        //登錄查看信息的賬號(hào)密碼.
        servletRegistrationBean.addInitParameter("loginUsername","admin");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否能夠重置數(shù)據(jù).
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }
    /**
     * druid過(guò)濾器
     * 注冊(cè)一個(gè)：filterRegistrationBean
     * @return
     */
    @Bean
    public FilterRegistrationBean druidStatFilter(){
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //添加過(guò)濾規(guī)則.
        filterRegistrationBean.addUrlPatterns("/*");
        //添加不需要忽略的格式信息.
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }
}

訪(fǎng)問(wèn)http://localhost:8080/druid/login.html，賬號(hào)密碼為上面代碼設(shè)置的

成功

三、springsecurity

1.引入相關(guān)依賴(lài)

<!-- Spring Security -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!-- fastjson -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.36</version>
</dependency>

2.寫(xiě)了幾個(gè)工具類(lèi)

ResultEnum

package com.deceen.common.Enums;
import lombok.Getter;
/**
 * @author: zzx
 * @date: 2018/10/15 15:16
 * @description: 返回的錯(cuò)誤碼枚舉類(lèi)
 */
@Getter
public enum ResultEnum {
    SUCCESS(101,"成功"),
    FAILURE(102,"失敗"),
    USER_NEED_AUTHORITIES(201,"用戶(hù)未登錄"),
    USER_LOGIN_FAILED(202,"用戶(hù)賬號(hào)或密碼錯(cuò)誤"),
    USER_LOGIN_SUCCESS(203,"用戶(hù)登錄成功"),
    USER_NO_ACCESS(204,"用戶(hù)無(wú)權(quán)訪(fǎng)問(wèn)"),
    USER_LOGOUT_SUCCESS(205,"用戶(hù)登出成功"),
    TOKEN_IS_BLACKLIST(206,"此token為黑名單"),
    LOGIN_IS_OVERDUE(207,"登錄已失效"),
    ;
    private Integer code;
    private String message;
    ResultEnum(Integer code, String message) {
        this.code = code;
        this.message = message;
    }
    /**
     * @author: zzx
     * @date: 2018-10-15 16:26
     * @deprecation:通過(guò)code返回枚舉
    */
    public static ResultEnum parse(int code){
        ResultEnum[] values = values();
        for (ResultEnum value : values) {
            if(value.getCode() == code){
                return value;
            }
        }
        throw  new RuntimeException("Unknown code of ResultEnum");
    }
}

ResultVO

package com.deceen.common.VO;
import com.deceen.common.Enums.ResultEnum;
import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;
/**
 * @author: zzx
 * @date: 2018/10/15 15:00
 * @description: 返回的格式
 */
public final class ResultVO implements Serializable {
   private static final long serialVersionUID = 1725159680599612404L;
   /**

    */
   public final static  Map<String, Object> success(String message, Object data,String jwtToken,Boolean success) {
      Map<String, Object> map = new HashMap<>();
      map.put("jwtToken",jwtToken);
      map.put("code", ResultEnum.SUCCESS.getCode());
      map.put("message", message);
      map.put("success",success);
      map.put("data", data);
      return map;
   }
   /**

      Map<String, Object> map = new HashMap<String, Object>();
      map.put("jwtToken",jwtToken);
      map.put("code", ResultEnum.SUCCESS.getCode());
      map.put("message", ResultEnum.SUCCESS.getMessage());
      map.put("data", data);
      map.put("success",true);
      return map;
   }
   /**

    */
   public final static  Map<String, Object> success() {

      map.put("jwtToken",null);
      map.put("code", ResultEnum.SUCCESS.getCode());
      map.put("message", ResultEnum.SUCCESS.getMessage());
      map.put("data", null);
      map.put("success",true);
      return map;
   }
   public final static  Map<String, Object> failure(int code, String message,Object data) {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("code", code);
      map.put("message", message);
      map.put("data", data);
      map.put("success",false);
      return map;
   }
   public final static  Map<String, Object> failure(int code, String message) {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("code", code);
      map.put("message", message);
      map.put("data", null);
      map.put("success",false);
      return map;
   }
   public final static  Map<String, Object> failure(ResultEnum respCode, Object data, Boolean success) {
      return getStringObjectMap(respCode, data,success);
   }
   public final static  Map<String, Object> failure(ResultEnum respCode, Boolean success) {
      return getStringObjectMap(respCode,success);
   }
   /*
   * 成功返回特定的狀態(tài)碼和信息
   * */
   public final static  Map<String, Object> result(ResultEnum respCode, Object data, Boolean success) {
      return getStringObjectMap(respCode, data,success);
   }
   private static  Map<String, Object> getStringObjectMap(ResultEnum respCode, Object data, Boolean success) {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("code", respCode.getCode());
      map.put("message", respCode.getMessage());
      map.put("data", data);
      map.put("success",success);
      return map;
   }
   /*
    * 成功返回特定的狀態(tài)碼和信息
    * */
   public final static  Map<String, Object> result(ResultEnum respCode, Boolean success) {
      return getStringObjectMap(respCode,success);
   }
   private static Map<String, Object> getStringObjectMap(ResultEnum respCode, Boolean success) {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("code", respCode.getCode());
      map.put("message", respCode.getMessage());
      map.put("data", null);
      map.put("success",success);
      return map;
   }
   /*
    * 成功返回特定的狀態(tài)碼和信息
    * */
   public final static Map<String, Object> result(ResultEnum respCode, String jwtToken, Boolean success) {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("jwtToken",jwtToken);
      map.put("code", respCode.getCode());
      map.put("message", respCode.getMessage());
      map.put("data", null);
      map.put("success",success);
      return map;
   }
}

可以看出來(lái)，我們后面是會(huì)集成jwt的token過(guò)來(lái)的，看得懂就行，后面根據(jù)需要改

下面就是springsecurity核心幾個(gè)東西啦，具體我還沒(méi)深入，等后面有時(shí)間再寫(xiě)一篇深入一點(diǎn)的（大體分析一下shiro和springsecurity吧。。。）

3.實(shí)現(xiàn)springsecurity各個(gè)核心接口，處理用戶(hù)各種狀態(tài)

實(shí)現(xiàn)AuthenticationEntryPoint接口，處理用戶(hù)未登錄

package com.deceen.common.security;

        httpServletResponse.getWriter().write(JSON.toJSONString(ResultVO.result(ResultEnum.USER_LOGIN_SUCCESS,jwtToken,true)));
    }
}

實(shí)現(xiàn)LogoutSuccessHandler接口，處理退出成功

    }
}

在這里展開(kāi)一下，為了實(shí)現(xiàn)前后端交互，采用了jjwt的方案，后面會(huì)加入更多的token驗(yàn)證，現(xiàn)在先把基本的東西弄出來(lái)。

大體是思路就是，每次登陸成功會(huì)返回token給前端做本地保存，以后每一次前端請(qǐng)求api都會(huì)在請(qǐng)求頭中帶上這個(gè)token，我們后面加入一個(gè)過(guò)濾器，專(zhuān)門(mén)攔截token然后驗(yàn)證。肯定會(huì)有人說(shuō)token暴露的問(wèn)題，我的解決方案很簡(jiǎn)單，實(shí)現(xiàn)一個(gè)黑名單，每一次登出或失效的token都加入黑名單（這一塊我用redis實(shí)現(xiàn)，用其他緩存數(shù)據(jù)庫(kù)都行，就是一個(gè)思路的問(wèn)題）。token生成的時(shí)候也會(huì)在redis加入相應(yīng)刷新時(shí)間和失效時(shí)間（例如：7天免登陸，即在7天內(nèi)會(huì)自動(dòng)刷新用戶(hù)的token；而失效時(shí)間定為十五分鐘，即每個(gè)token只有15分鐘有效時(shí)間，過(guò)了這個(gè)時(shí)間，會(huì)去判斷是否在刷新時(shí)間內(nèi)，如果是，則refresh token，并set進(jìn)request的請(qǐng)求頭之中）

    }
}

有個(gè)點(diǎn)說(shuō)一下：我密碼加密選擇了BCryptPasswordEncoder格式，官方也推薦這個(gè)，然后你們可以自行建一個(gè)測(cè)試用戶(hù)，記得密碼先用BCryptPasswordEncoder加密一下哦（寫(xiě)一個(gè)createUser方法，密碼加密保存）

測(cè)試

postman模擬請(qǐng)求：

登錄成功：

復(fù)制token，如下操作，進(jìn)行接口測(cè)試：

請(qǐng)求接口成功：

springboot+springsecurity+mybatis+JWT+Redis 實(shí)現(xiàn)前后端離（實(shí)戰(zhàn)篇續(xù)）

后記：

1.加入簡(jiǎn)單注冊(cè)功能，SpringSecurityConf加入配置放開(kāi)url，DemoController加入如下代碼

/**
 * 簡(jiǎn)單注冊(cè)功能
 * @param username
 * @param password
 * @return
 */
@PostMapping("/register")
public Map<String, Object> register(String username,String password){
	orderService.register(username,password);
	return ResultVO.result(ResultEnum.SUCCESS,true);
}

（詳細(xì)代碼我上傳到github了）

2.關(guān)于mysql新版本，導(dǎo)致mysql-connector-java版本對(duì)應(yīng)不上的問(wèn)題

mysql版本:

pom.xml更新對(duì)應(yīng)mysql-connector-java版本

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<version>8.0.11</version>
</dependency>

同時(shí)配置文件中關(guān)于數(shù)據(jù)庫(kù)連接地址需要加上&serverTimezone=GMT%2B8，即：

spring:
  datasource:
    username: root
    password: 123
    url: jdbc:mysql://localhost/springboot?characterEncoding=utf-8&useSSl=false&serverTimezone=GMT%2B8
    driver-class-name: com.mysql.jdbc.Driver

3.關(guān)于自定義登錄的

其實(shí)也很簡(jiǎn)單，但是我就不上傳了，簡(jiǎn)單說(shuō)一下spring security流程

這個(gè)流程很清楚啦

UsernamePasswordAuthenticationToken封裝加密后的密碼以及用戶(hù)信息

BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, bCryptPasswordEncoder.encode(password));
try {
	Authentication authentication = authenticationManager.authenticate(authenticationToken);
	SecurityContextHolder.getContext().setAuthentication(authentication);
	//具體實(shí)現(xiàn)。。。
} catch (AuthenticationException e) {
	//自行處理
}
