springboot中新增一个过滤器如下：
package com.rtpksps.kss.config;import org.springframework.stereotype.Component;import javax.servlet.*;import javax.servlet.http.HttpServletResponse;import java.io.IOException;/** * @author Administrator * @title: OriginFilter * @projectName rtpksps-kss * @description: TODO * @date 2019/9/29 0029下午 15:52 */@Componentpublic class OriginFilter implements Filter { @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletResponse response = (HttpServletResponse) servletResponse; response.setHeader("Access-Control-Allow-Origin", "*"); response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE,PUT"); response.setHeader("Access-Control-Max-Age", "3600"); response.setHeader("Access-Control-Allow-Headers", "x-requested-with"); filterChain.doFilter(servletRequest, servletResponse); } @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void destroy() { }}
在接口中指定需要的方法类型
angular页面发送http请求：
reqData(){ // 向后台请求数据 var url = "http://192.168.100.100:8888/cmsRole/show";//视频教程中的测试用请求地址 var _that = this; this.http.get(url).subscribe(function(data){//请求成功的回调函数 console.log(data); },function(err){// 请求失败的回调函数 console.log(err); }) }
