• 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

      下载地址:http://pan.baidu.com/s/1pLkLPGJ

    第二步:在web.xml文件配置

    <filter>
      <filter-name>CORS</filter-name>
      <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
      <init-param>
       <param-name>cors.allowOrigin</param-name>   <!--配置授信的白名单的域名! -->
       <param-value>*</param-value>
      </init-param>
      <init-param>
       <param-name>cors.supportedMethods</param-name>
       <param-value> GET, POST, HEAD, PUT, DELETE </param-value>
      </init-param>
      <init-param>
       <param-name>cors.supportedHeaders</param-name>
       <param-value> Accept, Origin, X-Requested-With, Content-Type, Last-Modified </param-value>
      </init-param>
      <init-param>
       <param-name>cors.exposedHeaders</param-name>
       <param-value>Set-Cookie</param-value>
      </init-param>
      <init-param>
       <param-name>cors.supportsCredentials</param-name>
       <param-value>true</param-value>
      </init-param>
     </filter>
     <filter-mapping>
      <filter-name>CORS</filter-name>
      <url-pattern>/*</url-pattern>
     </filter-mapping>
