**3. 实现一个SimpleUrlAuthenticationFailureHandler类**

package com.xunwu.security;
    
    import org.springframework.security.core.AuthenticationException;
    import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
    
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    /**
     * 登录验证失败处理器
     * Created by 瓦力.
     */
    public class LoginAuthFailHandler extends SimpleUrlAuthenticationFailureHandler {
        private final LoginUrlEntryPoint urlEntryPoint;
    
        public LoginAuthFailHandler(LoginUrlEntryPoint urlEntryPoint) {
            this.urlEntryPoint = urlEntryPoint;
        }
    
        @Override
        public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
                                            AuthenticationException exception) throws IOException, ServletException {
            String targetUrl =
                    this.urlEntryPoint.determineUrlToUseForThisRequest(request, response, exception);
    
            targetUrl += "?" + exception.getMessage();
            super.setDefaultFailureUrl(targetUrl);
            super.onAuthenticationFailure(request, response, exception);
        }
    }
