SpringSecurity+JWT实现前后端分离的使用详解

SpringSecurity+JWT实现前后端分离的使用详解

创建一个配置类 SecurityConfig 继承 WebSecurityConfigurerAdapter

package top.ryzeyang.demo.common.config;

import top.ryzeyang.demo.utils.JwtTokenUtil;

@EnableWebSecurity

@EnableGlobalMethodSecurity(prePostEnabled = true)

public class SecurityConfig extends WebSecurityConfigurerAdapter {

final AuthenticationFailureHandler authenticationFailureHandler;

final AuthenticationSuccessHandler authenticationSuccessHandler;

final AuthenticationEntryPoint authenticationEntryPoint;

final AccessDeniedHandler accessDeniedHandler;

final LogoutSuccessHandler logoutSuccessHandler;

public SecurityConfig(AuthenticationFailureHandler authenticationFailureHandler, AuthenticationSuccessHandler authenticationSuccessHandler, AuthenticationEntryPoint authenticationEntryPoint, AccessDeniedHandler accessDeniedHandler, LogoutSuccessHandler logoutSuccessHandler) {

this.authenticationFailureHandler = authenticationFailureHandler;

this.authenticationSuccessHandler = authenticationSuccessHandler;

this.authenticationEntryPoint = authenticationEntryPoint;

this.accessDeniedHandler = accessDeniedHandler;

this.logoutSuccessHandler = logoutSuccessHandler;

}

@Bean

public PasswordEncoder passwordEncoder() {

return PasswordEncoderFactories.createDelegatingPasswordEncoder();

}

@Bean("users")

public UserDetailsService users() {

UserDetails user = User.builder()

return new InMemoryUserDetailsManager(user, admin);

}

创建JWT过滤器 继承 OncePerRequestFilter

这里直接用的macro大佬 mall商城里的例子

package top.ryzeyang.demo.common.filter;

import lombok.extern.slf4j.Slf4j;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;

import org.springframework.security.core.context.SecurityContextHolder;

import org.springframework.security.core.userdetails.UserDetails;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;

import org.springframework.stereotype.Component;

import org.springframework.web.filter.OncePerRequestFilter;

import top.ryzeyang.demo.utils.JwtTokenUtil;

import javax.servlet.FilterChain;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

/**

* JWT登录授权过滤器

*

* @author macro

* @date 2018/4/26

*/

@Slf4j

public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {

@Qualifier("users")

@Autowired

private UserDetailsService userDetailsService;

@Autowired

private JwtTokenUtil jwtTokenUtil;

@Value("${jwt.tokenHeader}")

private String tokenHeader;

@Value("${jwt.tokenHead}")

private String tokenHead;

@Override

protected void doFilterInternal(HttpServletRequest request,

HttpServletResponse response,

FilterChain chain) throws ServletException, IOException {

String authHeader = request.getHeader(this.tokenHeader);

if (authHeader != null && authHeader.startsWith(this.tokenHead)) {

String authToken = authHeader.substring(this.tokenHead.length());// The part after "Bearer "

String username = jwtTokenUtil.getUserNameFromToken(authToken);

log.info("checking username:{}", username);

if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {

UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);

if (jwtTokenUtil.validateToken(authToken, userDetails)) {

UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());

authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));

log.info("authenticated user:{}", username);

SecurityContextHolder.getContext().setAuthentication(authentication);

}

}

}

chain.doFilter(request, response);

}

}

自定义handler

这里主要介绍两个hanler，一个权限不足，一个验证失败的

权限不足 实现 AccessDeniedHandler

package top.ryzeyang.demo.common.handler;

import com.fasterxml.jackson.databind.ObjectMapper;

import org.springframework.security.access.AccessDeniedException;

import org.springframework.security.web.access.AccessDeniedHandler;

import org.springframework.stereotype.Component;

import top.ryzeyang.demo.common.api.CommonResult;

import top.ryzeyang.demo.common.api.ResultEnum;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.io.PrintWriter;

@Component

public class MyAccessDeineHandler implements AccessDeniedHandler {

@Override

public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AccessDeniedException e) throws IOException, ServletException {

httpServletResponse.setContentType("application/json;charset=utf-8");

PrintWriter writer = httpServletResponse.getWriter();

writer.write(new ObjectMapper().writeValueAsString(new CommonResult<>(ResultEnum.ACCESS_ERROR, e.getMessage())));

writer.flush();

writer.close();

}

}

认证失败 实现 AuthenticationEntryPoint

如账号密码错误等验证不通过时

package top.ryzeyang.demo.common.handler;

import com.fasterxml.jackson.databind.ObjectMapper;

import org.springframework.security.core.AuthenticationException;

import org.springframework.security.web.AuthenticationEntryPoint;

import org.springframework.stereotype.Component;

import top.ryzeyang.demo.common.api.CommonResult;

import top.ryzeyang.demo.common.api.ResultEnum;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.io.PrintWriter;

@Component

public class MyAuthenticationEntryPoint implements AuthenticationEntryPoint {

@Override

public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {

httpServletResponse.setContentType("application/json;charset=utf-8");

PrintWriter writer = httpServletResponse.getWriter();

// 认证失败

writer.write(new ObjectMapper().writeValueAsString(new CommonResult<>(ResultEnum.AUTHENTICATION_ERROR, e.getMessage())));

writer.flush();

writer.close();

}

}

JWT工具类

这里直接用的macro大佬 mall商城里的例子

稍微改了一点，因为 JDK11 用的 jjwt 版本不一样 ，语法也有些不同

pom 文件中引入 jjwt

io.jsonwebtoken

jjwt-api

0.11.2

io.jsonwebtoken

jjwt-impl

0.11.2

runtime

io.jsonwebtoken

jjwt-jackson

0.11.2

这里的 secret 可以用该方法生成

@Test

void generateKey() {

/**

* String secretString = Encoders.BASE64.encode(key.getEncoded()); # 本文使用 BASE64 编码
