Tomcat跨域资源共享

1.下载Jar包

cors-filter-1.7.jar

java-property-utils-1.9.jar

下载完成后将Jar拷贝到tomcat下lib目录中

2.修改web.xml配置

在290行处加入以下配置

  <filter>       
    <filter-name>CORS</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
    <init-param>
      <param-name>cors.allowOrigin</param-name>
      <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>

修改配置后保存并重启Tomcat就OK了！
