我用的是spring MVC加maven的，废话不多说，来看代码

pom.xml中加入这些

<dependency>
       <groupId>com.thetransactioncompany</groupId>
       <artifactId>Java-property-utils</artifactId>
       <version>1.9</version>
       </dependency>
       <dependency>
       <groupId>com.google.code.gson</groupId>
       <artifactId>gson</artifactId>
       <version>2.6.2</version>
       </dependency>
       
       <dependency>
       <groupId>com.thetransactioncompany</groupId>
       <artifactId>cors-filter</artifactId>
       <version>1.3.2</version>
       </dependency>

web.xml中加入

<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>
