Question

我的Spring Boot（2.2 MI版）应用程序仅具有使用Spring Security通过httpBasic进行身份验证的REST端点。但是，当由于未启用用户等原因导致用户身份验证失败时，我想使用自定义Json进行响应，以便我的React Native应用程序适当地指导用户。但是，自定义AuthenticationFailureHandler似乎只能针对formLogin进行配置。

我只看到类似的例子

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，我需要下面类似的东西（似乎没有东西）

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

请让我知道，前进的最佳方法是什么？

更新：- 按照下面接受的答案，以下是自定义实现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

BasicAuthenticationFilter认证失败时，它将调用AuthenticationEntryPoint。默认值是BasicAuthenticationEntryPoint，您可以考虑编写自定义值或扩展自定义值：

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

并通过以下方式进行配置：

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

Spring boot（2.2 MI）安全性：为HttpBasic
