    前言

    本文章主要从spring security安全认证登录内部调用流程来流程分析登录过程。

    一、登录时序图

    SpringBoot security安全认证登录的实现方法

    时序原图

    二、配置与代码

    {
        return new BCryptPasswordEncoder();
    }
    /**
     * 身份认证接口
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception
    {
    //设置DaoAuthenticationProvider类PasswordEncoder passwordEncoder
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());
    }
}

    spring security配置类配置token认证过滤器（JwtAuthenticationTokenFilter）、

    认证失败处理类（AuthenticationEntryPointImpl）、退出处理类（LogoutSuccessHandlerImpl）

    1-JwtAuthenticationTokenFilter：

    package com.ems.mgr.framework.security.filter;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
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.web.filter.OncePerRequestFilter;
import com.ems.mgr.common.core.domain.model.LoginUser;
import com.ems.mgr.common.utils.SecurityUtils;
import com.ems.mgr.common.utils.StringUtils;
import com.ems.mgr.framework.web.service.TokenService;
/**
 * token过滤器 验证token有效性
 */
@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter
{
    @Autowired
    private TokenService tokenService;
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
            throws ServletException, IOException
    {
        LoginUser loginUser = tokenService.getLoginUser(request);
        if (StringUtils.isNotNull(loginUser) && StringUtils.isNull(SecurityUtils.getAuthentication()))
        {
            tokenService.verifyToken(loginUser);
            UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(loginUser, null, loginUser.getAuthorities());
            authenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
            SecurityContextHolder.getContext().setAuthentication(authenticationToken);
        }
        chain.doFilter(request, response);
    }
}

    2-AuthenticationEntryPointImpl:认证失败处理类 返回未授权

    package com编程客栈.ems.mgr.framework.security.handle;
import java.io.IOException;
import java.io.Serializable;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.ems.mgr.common.core.domain.AJAXResult;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;
import org.springframework.stereotype.Component;
import com.alibaba.fastjson.JSON;python
import com.ems.mgr.common.constant.HttpStatus;
import com.ems.mgr.common.utils.ServletUtils;
import com.ems.mgr.common.utils.StringUtils;
/**
 * 认证失败处理类 返回未授权
 * 
 * 
 */
@Component
public class AuthenticationEntryPointImpl implements AuthenticationEntryPoint, Serializable
{
    private static final long serialVersionUID = -8970718410437077606L;
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException e)
            throws IOException
    {
        int code = HttpStatus.UNAUTHORIZED;
        String msg = StringUtils.format("请求访问：{}，认证失败，无法访问系统资源", request.getRequestURI());
        ServletUtils.renderString(response, JSON.toJSONString(AjaxResult.error(code, msg)));
    }
}

    3-LogoutSuccessHandlerImpl:自定义退出处理类

    package com.ems.mgr.framework.security.handle;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.ems.mgr.common.constant.Constants;
import com.ems.mgr.common.core.domain.AjaxResult;
import com.ems.mgr.framework.manager.factory.AsyncFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;
import com.alibaba.fastjson.JSON;
import com.ems.mgr.common.constant.HttpStatus;
import com.ems.mgr.common.core.domain.model.LoginUser;
import com.ems.mgr.common.utils.ServletUtils;
import com.ems.mgr.common.utils.StringUtils;
import com.ems.mgr.framework.manager.AsyncManager;
import com.ems.mgr.framework.web.service.TokenService;
/**
 * 自定义退出处理类 返回成功
 */
@Configuration
public class LogoutSuccessHandlerImpl implementspython LogoutSuccessHandler
{
    @Autowired
    private TokenService tokenService;
    /**
     * 退出处理
     * 
     * @return
     */
    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
            throws IOException, ServletException
    {
        LoginUser loginUser = tokenService.getLoginUser(request);
        if (StringUtils.isNotNull(loginUser))
        {
            String userName = loginUser.getUsername();
            // 删除用户缓存记录
            tokenService.delLoginUser(loginUser.getToken());
            // 记录用户退出日志
            www.devze.comAsyncManager.me().execute(AsyncFactory.recordLogininfor(userName, Constants.LOGOUT, "退出成功"));
        }
        ServletUtils.renderString(response, JSON.toJSONString(AjaxResult.error(HttpStatus.SUCCESS, "退出成功")));
    }
}
