Tomcat 6 跨域的支持

1.添加2个jar包 这个我是自己保存在云端的 

cors-filter-1.7.jar

java-property-utils-1.9.jar

tomcat7以后自动支持

2.tomcat 下面的web.xml  在最前面添加下面的filter

<filter>
<filter-name>CORS</filter-name>
<filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CORS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

or

<!-- 实现跨域 -->
<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>
