在使用 vue 做前端開發(fā)時托酸，碰到 vue 請求接口出現(xiàn)跨域問題赁炎。
解決的方法，就在后臺添加一個跨域請求的過濾器爬虱，來添加跨域支持
package com.reapal.openapi.web.config;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
