SpringSecurity +oauth2自定义异常（三）

特别注意：以下内容如果有疑问，可先学习：SpringSecurity +oauth2获取当前登录用户（二）

1 对token无效或不传递的处理，原始报错如下：

{
    "error": "unauthorized",
    "error_description": "Full authentication is required to access this resource"
}

对此，显然不满足开发需求，整改如下；

新建AuthExceptionEntryPoint.java类，实现AuthenticationEntryPoint类，代码如下：

package com.yty.system.oauth.config.exception;

import com.alibaba.fastjson.JSONObject;
import com.baomidou.mybatisplus.extension.api.R;
import org.springframework.http.HttpStatus;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.oauth2.common.exceptions.InvalidTokenException;
import org.springframework.security.web.AuthenticationEntryPoint;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.Objects;

/**
 * 无效 token 异常类重写
 */

@Component
public class AuthExceptionEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {
        Map map = new HashMap();
        Throwable cause = authException.getCause();

        response.setStatus(HttpStatus.OK.value());
        response.setHeader("Content-Type", "application/json;charset=UTF-8");
        try {
            if (Objects.isNull(cause)) {
                R
