Spring Security自定义认证成功处理器响应

创建CustomAuthenticationSuccessHandler

package com.mengxuegu.security.authentication;

import com.mengxuegu.base.result.MengxueguResult;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.stereotype.Component;

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

/**
 * 认证成功处理器
 * 1. 决定 响应json还是跳转页面，或者认证成功后进行其他处理
 * @Auther: 梦学谷 www.mengxuegu.com
 */
@Component("customAuthenticationSuccessHandler")
public class CustomAuthenticationSuccessHandler implements AuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request,
        HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        // 认证成功后，响应JSON字符串
        MengxueguResult result = MengxueguResult.ok("认证成功");
        response.setContentType("application/json;charset=UTF-8");
        response.getWriter().write(result.toJsonString());
    }
}

修改配置文件
