sprintboot+spring security +jwt 实现登录

直接上代码吧

1.maven依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt</artifactId>
            <version>0.9.0</version>
        </dependency>    

2.security配置类 继承WebSecurityConfigurerAdapter

3.调用失败的节点配置

package cn.likui.study.auth;

import cn.likui.study.entity.CodeType;
import cn.likui.study.entity.ResponseMessage;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;
import org.springframework.stereotype.Component;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Serializable;

/**
* @Description: 认证失败之后调用的接口.验证为未登陆状态会进入此方法，认证错误.
* @Author: ldg
* @Date: 2020/10/14
*/
@Slf4j
@Component
public class JwtAuthenticationEntryPoint implements AuthenticationEntryPoint, Serializable {
    @Override
    public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
                         AuthenticationException e) throws IOException {

        log.info("EntryPoint");
        log.info("认证失败：{}", e.getMessage());
        log.info("请求URI: {}", httpServletRequest.getRequestURI());

        httpServletResponse.setStatus(200);
        httpServletResponse.setCharacterEncoding("UTF-8");
        httpServletResponse.setContentType("application/json; charset=utf-8");

        PrintWriter printWriter = httpServletResponse.getWriter();
        ResponseMessage<?> message = ResponseMessage.error(CodeType.TOKEN_UNAUTHORIZED);
        String body = message.toJson();
        printWriter.write(body);
        printWriter.flush();
    }
}

4.权限不够的处理对象

package cn.likui.study.auth;

import cn.likui.study.entity.CodeType;
import cn.likui.study.entity.ResponseMessage;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.web.access.AccessDeniedHandler;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

/**
* @Description: 权限不够调用的接口.
* @Author: ldg
* @Date: 2020/10/14
*/
@Slf4j
@Component("SysAccessDeniedHandler")
public class SysAccessDeniedHandler implements AccessDeniedHandler {
    @Override
    public void handle(HttpServletRequest httpServletRequest, HttpServletResponse response, AccessDeniedException e) throws IOException, ServletException {
        //登陆状态下，权限不足执行该方法
        log.info("权限不足：" + e.getMessage());
        response.setStatus(200);
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/json; charset=utf-8");
        PrintWriter printWriter = response.getWriter();
        ResponseMessage<?> message = ResponseMessage.error(CodeType.TOKEN_FORBIDDEN.getCode(), e.getMessage());
        String body = message.toJson();
        printWriter.write(body);
        printWriter.flush();
    }
}

5.网关拦截,获取Token

package cn.likui.study.filters;

import cn.likui.study.entity.CodeType;
import cn.likui.study.entity.ResponseMessage;
import cn.likui.study.entity.SysUserDetail;
import cn.likui.study.utils.JwtUtil;
import com.github.pagehelper.util.StringUtil;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.ExpiredJwtException;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
import org.springframework.stereotype.Component;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.RequestMethod;
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.io.PrintWriter;

/**
