在spring启动时REST API的身份验证失败时从Java类发送自定义JSON

我已经粘贴了上面代码的一部分。我还扩展了三个类，并将它们注入bean AuthenticationEntryPoint、SimpleRulAuthenticationFailureHandler、SimpleRulAuthenticationSuccessHandler，认为我可以扩展它们，并尝试在身份验证失败时获取自定义错误消息。我在restapi中得到了标准的springauth失败，它工作得很好，但是我想定义我自己的类，甚至在资源端点发挥作用之前，我想在auth层将其作为响应发送。就像我自己的自定义类和我自己的数据成员一样。目前，我得到了默认错误的情况下，错误的身份验证

{“timestamp”：1469955305299，“status”：401，“error”：“Unauthorized”，“message”：“Bad credentials”，“path”：“/secure/hello”}

这就是我用错误的pwd执行rest调用的方式

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    private RESTAuthenticationEntryPoint authenticationEntryPoint;
    @Autowired
    private RESTAuthenticationFailureHandler authenticationFailureHandler;
    @Autowired
    private RESTAuthenticationSuccessHandler authenticationSuccessHandler;

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers("/hello").permitAll()
                .antMatchers("/secure/hello").authenticated()
                .and()
                .httpBasic()
                .realmName("KS TEST")
                .and()
                .csrf()
                .disable();

        http.exceptionHandling().authenticationEntryPoint(authenticationEntryPoint);
        http.formLogin().successHandler(authenticationSuccessHandler);
        http.formLogin().failureHandler(authenticationFailureHandler);
        http.logout().logoutSuccessUrl("/");

    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

如果我给了正确的pwd，事情会按预期进行。然而，在一个错误的例子中，假设我想要一个可以填充的类，并在auth层成为json响应。有人能告诉我需要做什么吗

//REST API execution example
curl  -v -u mickey:cheesee http://localhost:8080/secure/hello
