1.将java-property-utils-1.9.1.jar 和 cors-filter-2.6.jar放到tomcat的lib目录下

http://search.maven.org/remotecontent?filepath=com/thetransactioncompany/java-property-utils/1.9.1/java-property-utils-1.9.1.jar

http://search.maven.org/remotecontent?filepath=com/thetransactioncompany/cors-filter/2.6/cors-filter-2.6.jar

2.修改tomcat的web.xml，追加以下信息：

<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>
