Spring Security自定义认证失败处理器响应

自定义认证失败处理器

package com.mengxuegu.security.authentication;

import com.mengxuegu.base.result.MengxueguResult;
import org.springframework.http.HttpStatus;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.stereotype.Component;

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

@Component("customAuthenticationFailureHandler")
public class CustomAuthenticationFailureHandler implements AuthenticationFailureHandler {
    @Override
    public void onAuthenticationFailure(HttpServletRequest httpServletRequest,
                                        HttpServletResponse httpServletResponse,
                                        AuthenticationException e) throws IOException, ServletException {
        MengxueguResult result = MengxueguResult.build(
                HttpStatus.UNAUTHORIZED.value(), e.getMessage());
        httpServletResponse.setContentType("application/json;charset=UTF-8");
        httpServletResponse.getWriter().write(result.toJsonString());
    }
