java后台接口SSM框架解决跨域问题

这几天和前端对接接口，前端的错误信息是：

 

　注释：
　　Failed to load http://192.168.3.3:8080/Light_Push/webFrames.action?page=1&searchProject=1&page=1&searchProject=1: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 　　　　　　       'http://localhost:8080' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

前端用了vue，axios（http客户端）
后端ssm框架，spring版本是3.2.13

发现可以从后台spring跨域着手解决

解决跨域方法：

第一步：导入jar包

　　cors-filter-1.7.jar、java-property-utils-1.9.jar

第二步：在web.xml文件配置

  CORS
  com.thetransactioncompany.cors.CORSFilter
  
   cors.allowOrigin  
   *
  
  
   cors.supportedMethods
    GET, POST, HEAD, PUT, DELETE
  
  
   cors.supportedHeaders
    Accept, Origin, X-Requested-With, Content-Type, Last-Modified
  
  
   cors.exposedHeaders
   Set-Cookie
  
  
   cors.supportsCredentials
   true
  
 
 
  CORS
