我正在尝试在$ CATALINA_BASE/conf/web.xml文件中实现基本的CORS过滤器.这是我的过滤器:

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

我已经确认我肯定在运行受支持的Tomcat版本:

Server version: Apache Tomcat/7.0.56
Server built:   Sep 26 2014 12:08:24
Server number:  7.0.56.0

这是我的AJAX请求:

function MethodOne() {
$.ajax({
    type: "GET",
    url: "http://localhost:8080/crossDomain",
    crossDomain: true,
    success: function(response) {
        $('#result').html(response);
    }   
});
}

我的请求/响应标头:

Remote Address:[::1]:8080
Request URL:http://localhost:8080/crossDomain
Request Method:GET
Status Code:302 Found
