Ajax中的Access

您必须使用CORS。

为了那个原因：

1. 您必须使用cors-filter jar
2. 然后，您必须在web.xml中使用过滤器：

        <filter>    <filter-name>CORS</filter-name>    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>    <init-param>        <param-name>cors.allowGenericHttpRequests</param-name>        <param-value>true</param-value>    </init-param>    <init-param>        <param-name>cors.allowOrigin</param-name>        <param-value>*</param-value>    </init-param>    <init-param>        <param-name>cors.allowSubdomains</param-name>        <param-value>true</param-value>    </init-param>    <init-param>        <param-name>cors.supportedMethods</param-name>        <param-value>GET, HEAD, POST, OPTIONS</param-value>    </init-param>    <init-param>        <param-name>cors.supportedHeaders</param-name>        <param-value>Content-Type, X-Requested-With</param-value>    </init-param>    <init-param>        <param-name>cors.exposedHeaders</param-name>        <param-value>X-Test-1, X-Test-2</param-value>    </init-param>    <init-param>        <param-name>cors.supportsCredentials</param-name>        <param-value>true</param-value>    </init-param>    <init-param>        <param-name>cors.maxAge</param-name>        <param-value>-1</param-value>    </init-param>    </filter>    <filter-mapping>    <filter-name>CORS</filter-name>     <url-pattern>/EmployeeResource</url-pattern>    </filter-mapping>
