在使用 Spring Security 做权限管理的时候，授权登录成功后，一般是跳转到首页。但是我们想再授权成功一瞬间做一些额外的操作，比如记录日志，添加 Session 等。

具体做法如下

创建 SecurityConfig 类，继承 WebSecurityConfigurerAdapter

重写 protected void configure(HttpSecurity http) 方法

在里面添加如下代码

.successHandler(new AuthenticationSuccessHandler() {
@Override
public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
if (principal != null && principal instanceof UserDetails) {
UserDetails user = (UserDetails) principal;
//1、添加 Session
httpServletRequest.getSession().setAttribute("userDetail", user);
//2、写入日志
logger.info("【用户已登录】" + user.getUsername());
//3、写入数据库login_record表
LoginRecord loginRecord = new LoginRecord();
loginRecord.setLoginIp(IPUtil.getIpAddr(httpServletRequest));
loginRecord.setLoginTime(System.currentTimeMillis());
loginRecord.setUser((User) user);
loginRecordRepository.save(loginRecord);
//4、页面跳转到首页
httpServletResponse.sendRedirect(ctx);//即 /forum
}
}
})

第 7 行-第 19 行是自定义操作

完整代码如下
