完成历程

  • 在开辟项目中到场支撑库,或把支撑库直接丢到tomcat的lib目录下，下载地点：http://cdn.besdlab.cn/cors-li…

  • 修正web.xml，增添以下代码

<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>
