Spring boot（2.2 MI）安全性：为HttpBasic配置自定义AuthenticationFailureHandler

Question

我的Spring Boot（版本2.2 MI）应用程序只使用spring安全性使用httpBasic进行身份验证的REST端点。但是，当用户身份验证因用户未启用等而失败时，我想回复自定义Json，以便我的React Native应用程序适当地引导用户。但是，自定义AuthenticationFailureHandler似乎只能为formLogin配置。

我只看到例子

http.
   formLogin().
       failureHandler(customAuthenticationFailureHandler());

public class CustomAuthenticationFailureHandler
   implements AuthenticationFailureHandler {
       @Override
       public void onAuthenticationFailure(
           HttpServletRequest request,
           HttpServletResponse response,
           AuthenticationException exception)
           throws IOException, ServletException {
       }
}
@Bean
public AuthenticationFailureHandler customAuthenticationFailureHandler() {
    return new CustomAuthenticationFailureHandler();
}

但是，我需要下面的东西（似乎没有）

http.
   httpBasic().
       failureHandler(customAuthenticationFailureHandler());

请告诉我，最好的方法是什么？

更新： - 根据下面接受的答案，下面是自定义实现CustomBasicAuthenticationEntryPoint

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class CustomBasicAuthenticationEntryPoint extends BasicAuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
                         AuthenticationException authException) throws IOException, ServletException {
        response.addHeader("WWW-Authenticate", "Basic realm=\"" + this.getRealmName() + "\"");
        //response.sendError( HttpStatus.UNAUTHORIZED.value(), "Test msg response");
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");
        response.getWriter().write("{ \"val\":\"Venkatesh\"}");
    }
}

@Bean
    public AuthenticationEntryPoint customBasicAuthenticationEntryPoint() {
        CustomBasicAuthenticationEntryPoint obj = new CustomBasicAuthenticationEntryPoint();
        obj.setRealmName("YourAppName");
        return obj;
    }

protected void configure(HttpSecurity http) throws Exception{
        http.httpBasic().
                authenticationEntryPoint(customBasicAuthenticationEntryPoint());
}

Answer 1

当BasicAuthenticationFilter无法验证时，它将调用AuthenticationEntryPoint。默认的是BasicAuthenticationEntryPoint，您可以考虑编写自定义或扩展它：

@Bean
public AuthenticationEntryPoint customBasicAuthenticationEntryPoint() {
    return new CustomBasicAuthenticationEntryPoint();
}

并通过以下方式配置：

   http.httpBasic().authenticationEntryPoint(customBasicAuthenticationEntryPoint())
