1、添加依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.9.1</version>
</dependency>
2、集成JWT工具类(JwtUtils)
package com.dreamteam.chdapp.utils;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import javax.servlet.http.HttpServletRequest;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
/**
* @Author HeYunHui
* @create 2020/11/15 14:12
*/
public class JwtUtils {
private static final Logger logger= LoggerFactory.getLogger(JwtUtils.class);
public static final long EXPIRATION_TIME=60*60*1000;// 令牌环有效期
public static final String SECRET="abc123456def";//令牌环密钥
public static final String TOKEN_PREFIX="Bearer";//令牌环头标识
public static final String HEADER_STRING="Passport";//配置令牌环在http heads中的键值
public static final String ROLE="ROLE";//自定义字段-角色字段
//生成令牌环
public static String generateToken(String userRole,String userid){
HashMap<String,Object> map=new HashMap<>();
map.put(ROLE,userRole);
map.put("userid",userid);
String jwt= Jwts.builder()
.setClaims(map)
.setExpiration(new Date(System.currentTimeMillis()+EXPIRATION_TIME))
.signWith(SignatureAlgorithm.HS512,SECRET)
.compact();
return TOKEN_PREFIX+" "+jwt;
}
//生成令牌环
public static String generateToken(String userRole,String userid,long exprationtime){
HashMap<String,Object> map=new HashMap<>();
map.put(ROLE,userRole);
map.put("userid",userid);
String jwt= Jwts.builder()
.setClaims(map)
.setExpiration(new Date(System.currentTimeMillis()+exprationtime))
.signWith(SignatureAlgorithm.HS512,SECRET)
.compact();
return TOKEN_PREFIX+" "+jwt;
}
//令牌环校验
public static Map<String,Object> validateTokenAndGetClaims(HttpServletRequest request){
String token=request.getHeader(HEADER_STRING);
if(token==null){
throw new TokenValidationException("Missing Token");
}
else{
Map<String,Object> body= Jwts.parser()
.setSigningKey(SECRET)
.parseClaimsJws(token.replace(TOKEN_PREFIX,""))
.getBody();
return body;
}
}
static class TokenValidationException extends RuntimeException{
public TokenValidationException(String msg){
super(msg);
}
}
}
3、集成JWT filter(拦截器/过滤器)
package com.dreamteam.chdapp.filter;
import com.dreamteam.chdapp.utils.JwtUtils;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.util.AntPathMatcher;
import org.springframework.util.PathMatcher;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Arrays;
import java.util.Map;
import static com.dreamteam.chdapp.utils.JwtUtils.ROLE;
/**
* @Author HeYunHui
* @create 2020/11/15 14:46
*/
public class JwtAuthenticationFilter extends OncePerRequestFilter {
private static final PathMatcher pathmatcher = new AntPathMatcher();
private String[] protectUrlPattern = {"/manage/**", "/member/**", "/auth/**"}; //哪 些请求需要进行安全校验
public JwtAuthenticationFilter() {
}
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
//是不是可以在这里做多种方式登录呢
try {
if (isProtectedUrl(httpServletRequest)) {
Map<String, Object> claims = JwtUtils.validateTokenAndGetClaims(httpServletRequest);
String role = String.valueOf(claims.get(ROLE));
String userid = String.valueOf(claims.get("userid"));
//最关键的部分就是这里, 我们直接注入了
SecurityContextHolder.getContext().setAuthentication(new UsernamePasswordAuthenticationToken(
userid, null, Arrays.asList(() -> role)
));
}
} catch (Exception e) {
e.printStackTrace();
httpServletResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED, e.getMessage());
return;
}
filterChain.doFilter(httpServletRequest, httpServletResponse);
}
//是否是保护连接
private boolean isProtectedUrl(HttpServletRequest request) {
boolean flag = false;
for (int i = 0; i < protectUrlPattern.length; i++) {
if (pathmatcher.match(protectUrlPattern[i], request.getServletPath())) {
return true;
}
}
return false;
}
}
4、配置JWT config类(配置类)
跨域访问：客户端与服务端域名不同或是端口号不同。防止跨域攻击
package edu.ynmd.cms.config;
import edu.ynmd.cms.filter.JwtAuthenticationFilter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.security.web.firewall.HttpFirewall;
import org.springframework.security.web.firewall.StrictHttpFirewall;
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
StrictHttpFirewall firewall = new StrictHttpFirewall();
firewall.setAllowUrlEncodedSlash(true);
return firewall;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.cors() //允许跨域访问
.and()
.authorizeRequests()
.antMatchers("/").authenticated() //配置那些url需要进行校验--所有请求都需要校验"/"
.antMatchers("/public/**").permitAll() //那些请求不需要校验
.anyRequest().authenticated() //自定义校验类
.and()
.addFilterBefore(new JwtAuthenticationFilter(),
UsernamePasswordAuthenticationFilter.class)
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)//关闭session
;
}
}
5、Action注解
在Controller类中添加
@CrossOrigin
@RestController
@PreAuthorize("hasAuthority('admin')") //配置角色，拥有该角色的用户方可访问
@RequestMapping("/manage")
postman测试http://localhost:7070/manage/userList，不可访问
public开头的可以访问
6、token令牌环，访问需校验的资源
public的Controller类添加
@PostMapping("/login")
@ResponseBody
public HashMap<String,String> login(
@RequestBody Account account) throws IOException {
// Users u=manageService.getUserByUserNameAndPass(account.username,account.password);
if(account.username.equals("admin")&&account.password.equals("123456")){
// if(u!=null){
String jwt= JwtUtils.generateToken("admin","123456789abc");
// String jwt= JwtUtils.generateToken(u.getRoleid(),u.getUsersid());
return new HashMap<String,String>(){{
put("msg","ok");
put("token",jwt);
// put("role",u.getRoleid());
put("role","admin");
}};
}
else {
//return new ResponseEntity(HttpStatus.UNAUTHORIZED);
return new HashMap<String,String>(){{
put("msg","error");
put("token","error");
}};
}
}
public static class Account{
public String username;
public String password;
}
postman测试，随便输用户名密码
输入代码中的用户名密码
去JWT官网https://jwt.io/，页面下滑，将得到的token输入，得到
manage的Controller类中添加测试
@GetMapping("testSecurityResource")
@ResponseBody
public String testSecurityResource() throws Exception{
return "受保护的资源";
}
用postman访问http://localhost:7070/manage/testSecurityResource，返回结果
7、service工具类
通用请求处理
package com.dreamteam.chdapp.controller.common;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
/**
* 通用请求处理
* @Author HeYunHui
* @create 2020/11/14 15:38
*/
@Controller
public class CommonController {
protected static final Logger log= LoggerFactory.getLogger(CommonController.class);
/**
* 字符串为空
* @param value
* @return
*/
public static boolean isNullOrSpace(String value){
if(value==null){
return true;
}
else {
if(value.equals("")){
return true;
}
else {
return false;
}
}
}
}
Service层
String getCurrentUserId();//从令牌环中获取userid String getCurrentRole();//从令牌环中获取角色id
ServiceImpl
/**
* 获取当前登录用的的Id
* @return
*/
@Override
public String getCurrentUserId() {
String userid= (String) SecurityContextHolder.getContext().getAuthentication() .getPrincipal();
if(CommonController.isNullOrSpace(userid)){
return null;
}
else {
return userid;
}
}
/**
* 获取当前登录用户的角色
* @return
*/
@Override
public String getCurrentRole() {
String role=null;
Collection<SimpleGrantedAuthority> authorities = (Collection<SimpleGrantedAuthority>) SecurityContextHolder.getContext().getAuthentication().getAuthorities();
for (GrantedAuthority authority : authorities) {
role = authority.getAuthority();
}
if(CommonController.isNullOrSpace(role)){
return null;
}
else{
return role;
}
}
修改manage的Controller类
@GetMapping("testSecurityResource")
@ResponseBody
public String testSecurityResource() throws Exception{
String userid=userInfoService.getCurrentUserId();
String role=userInfoService.getCurrentRole();
return "受保护的资源,当前用户的id是"+userid+"当前用户的角色是"+role;
}
用postman测试
这是前面自定义的
8、识别token信息
如果将下图中的角色换掉，将不能访问
9、自动更新令牌环
添加Controller类
package com.dreamteam.chdapp.controller;
import com.dreamteam.chdapp.controller.common.CommonController;
import com.dreamteam.chdapp.utils.JwtUtils;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpServletRequest;
import java.util.Collection;
import java.util.HashMap;
/**
* 令牌环自动更新
* @Author HeYunHui
* @create 2020/11/16 17:24
* @PreAuthorize("hasAuthority('admin')")//只允许有admin角色的用户访问 hasAnyAuthority([auth1,auth2])
*/
@CrossOrigin
@RestController
@PreAuthorize("hasAnyAuthority('admin','member')")
@RequestMapping("/auth")
public class AuthController {
/**
* 更新令牌环信息
* @param request
* @return
*/
@GetMapping("refreshToken")
@ResponseBody
public HashMap<String,String> refreshToken(HttpServletRequest request){
String role=null;
Collection<SimpleGrantedAuthority> authorities = (Collection<SimpleGrantedAuthority>) SecurityContextHolder.getContext().getAuthentication().getAuthorities();
for (GrantedAuthority authority : authorities) {
role = authority.getAuthority();
}
// UserDetails userDetails = (UserDetails) SecurityContextHolder.getContext().getAuthentication() .getPrincipal();
String userid= (String)SecurityContextHolder.getContext().getAuthentication() .getPrincipal();
if(CommonController.isNullOrSpace(role)){
return new HashMap<String,String>(){{
put("token","error");
}};
}
else{
String jwt="";
//一小时
jwt= JwtUtils.generateToken(role,userid,60*60*1000);
HashMap<String,String> m=new HashMap<>();
m.put("token",jwt);
return m;
}
}
/**
* 获取当前登录用户的角色
* @return
*/
@GetMapping("getRole")
@ResponseBody
public HashMap<String,String> getRoleByToken(){
String role="";
String userid="";
Collection<SimpleGrantedAuthority> authorities = (Collection<SimpleGrantedAuthority>) SecurityContextHolder.getContext().getAuthentication().getAuthorities();
for (GrantedAuthority authority : authorities) {
role = authority.getAuthority();
}
if(CommonController.isNullOrSpace(role)){
return new HashMap<String,String>(){{
put("role","error");
}};
}
else{
HashMap<String,String> m=new HashMap<>();
m.put("role",role);
return m;
}
}
}
用postman测试
10、使用数据库存储用户信息
（1）实体类
package com.dreamteam.chdapp.entity;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.stereotype.Component;
@Component
@Data
@AllArgsConstructor
@NoArgsConstructor
/**
* 表名
*/
@TableName("users")
public class Users {
@TableId(type = IdType.AUTO)
private String usrId;
private String usrName;
private String usrTel;
private String usrPwd;
private String usrType;
}
UserMapper
package com.dreamteam.chdapp.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.dreamteam.chdapp.entity.Users;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* @Author HeYunHui
* @create 2020/11/11 21:50
*/
@Repository
@Mapper
public interface UserMapper extends BaseMapper<Users> {
List<Users> getUsersByUsrNameAndPwd(@Param("usrName")String usrName, @Param("usrPwd") String usrPwd);
}
UsersMapper.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.dreamteam.chdapp.mapper.UserMapper">
<select id="getUsersByUsrNameAndPwd" resultType="com.dreamteam.chdapp.entity.Users">
select * from users where #{usrName}=usr_name and #{usrPwd}=usr_pwd
</select>
</mapper>
service
Users getUsersByUsrNameAndPwd(String usrName,String usrPwd);
serviceImpl JWT获取用户名密码
@Override
public Users getUsersByUsrNameAndPwd(String usrName, String usrPwd) {
List<Users> ul=userMapper.getUsersByUsrNameAndPwd(usrName,usrPwd);
if(ul.size()>0){
return ul.get(0);
}
return null;
}
Controller
@PostMapping("/login")
@ResponseBody
public HashMap<String,String> login(
@RequestBody Account account) throws IOException {
Users u=userInfoService.getUsersByUsrNameAndPwd(account.username,account.password);
// if(account.username.equals("admin")&&account.password.equals("123456")){
if(u!=null){
// String jwt= JwtUtils.generateToken("admin","123456789abc");
String jwt= JwtUtils.generateToken(u.getUsrType(),u.getUsrId());
return new HashMap<String,String>(){{
put("msg","ok");
put("token",jwt);
put("role",u.getUsrType());
// put("role","admin");
}};
}
else {
//return new ResponseEntity(HttpStatus.UNAUTHORIZED);
return new HashMap<String,String>(){{
put("msg","error");
put("token","error");
}};
}
}
public static class Account{
public String username;
public String password;
}
postman测试
a.登录，生成token
b.输入token访问manage下的链接
