- 修改WebSecurityConfig配置文件支持自定义Handler
@Autowired

@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
// 允许直接访问/路径
.authorizeRequests().antMatchers("/").permitAll()
// 使其支持跨域
.requestMatchers(CorsUtils::isPreFlightRequest).permitAll()
// 其他路径需要授权访问
.anyRequest().authenticated()
// 指定登录页面
.and().formLogin().loginPage("/user/login")
// 指定登录失败跳转地址, 使用自定义错误信息
.failureHandler(customAuthenticationFailHander)
// 登录成功后的默认路径
.defaultSuccessUrl("/").permitAll()
// 退出登录后的默认路径
.and().logout().logoutSuccessUrl("/user/login").permitAll();
