SSM跨域配置

1.后台跨域要引用两个jar包（cors-filter-1.7.jar、java-property-utils-1.9.jar）

2.在web.xml中配置跨域过滤器

<!-- 跨域过滤器 -->     <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>

此时便可跨域访问项目。
