SpringSecurity自定义AuthenticationSuccessHandler不起作用无效被忽略，设置successHandler无效，successhandler不执行

登录时，自定义登录成功的handler不会执行，已经在security中配置了处理器，代码如下

handler

@Component
public class SecurityAuthSuccessHandler implements AuthenticationSuccessHandler {

    /**
     * 验证成功后执行
     * @param request 请求对象
     * @param response 响应对象
     * @param authentication security验证成功后的封装对象，包括用户的信息
     * @throws IOException
     * @throws ServletException
     */
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        // 登录的用户验证成功后执行
        response.setContentType("text/json;charset=utf-8");
        System.out.println("success handler...");
        Result result = new Result();
        result.setCode(0);
        result.setStatus(200);
        result.setMsg("登录成功");
        // 使用jsckson
        ObjectMapper mapper = new ObjectMapper();
        ServletOutputStream outputStream = response.getOutputStream();
        mapper.writeValue(outputStream, result);

        outputStream.flush();
        outputStream.close();

    }
}

security配置

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        return http
                .authorizeHttpRequests(auth->{

                    // 设置url权限，注意所有权限的配置顺序
                    auth.requestMatchers("/home").permitAll();
                    auth.anyRequest().authenticated();
                })
                .formLogin(conf->{
                    // 自定义表单登录页
                    // https://docs.spring.io/spring-security/reference/servlet/authentication/passwords/form.html
                    conf.loginPage("/login");
                    // 表单登录请求
                    conf.loginProcessingUrl("/login");
                    // 登录成功处理器，取消defaultSuccessUrl默认登录成功页可以看到效果，如登录失败处理器类似
                    // 使用handler类
                    conf.successHandler(successHandler);
                    conf.failureHandler(failureHandler);
                    // 默认登录成功页，使用了handler，就不要使用默认登录页，否则handler不起作用
                    // conf.defaultSuccessUrl("/home");
                    // 登录相关请求不需要认证
                    conf.permitAll();
                })
                .logout(conf->{
                    // 登出请求
                    conf.logoutUrl("/logout");
                    conf.logoutSuccessUrl("/login");
                    conf.permitAll();
                })
                // 使用自定义过滤器，并且
                .addFilterBefore(new VerificationFilter(), UsernamePasswordAuthenticationFilter.class)
                // 使用自定义的userDetails认证过程，
                // .userDetailsService(null)
                .csrf(AbstractHttpConfigurer::disable)// 关闭跨站请求伪造保护功能
                .build();
    }
}

原因是使用了自定义的handler，就不要设置跳转默认成功页了

	// 注释掉
	// conf.defaultSuccessUrl("/home");

参考java - Spring boot AuthenticationSuccessHandler ignore - Stack Overflow

Your is overriden by default handler in your security config.CustomSuccessHandler

Just delete following line: from class.defaultSuccessUrl("/")SecurityConfiguration
