关于tomcate跨域配置的配置问题和表头加入新属性的过滤

1 、在项目中常常遇到本地访问服务器上的链接数据访问不到，并出现如下问题：

这是因为tomcate 的配置中过滤了请求方式，

解决方案：

1、在tomcate中引入两个jar包：java-property-utils-1.9.1.jar；cors-filter-1.7.1.jar。 http://pan.baidu.com/s/1jHZYkpK    ，将两个包放在配置的tomcate下的lib中。

2、修改tomcate下的conf/web.xml，添加内容如下：

 1       <filter>
 2         <filter-name>CORS</filter-name>
 3         <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
 4         <init-param>
 5             <param-name>cors.allowOrigin</param-name>
 6             <param-value>*</param-value>
 7         </init-param>
 8         <init-param>
 9             <param-name>cors.supportedMethods</param-name>
10             <param-value>GET,POST,HEAD,PUT,DELETE</param-value>
11         </init-param>
12         <init-param>
13             <param-name>cors.supportedHeaders</param-name>
14             <param-value>Accept,Origin,X-Requested-With,Content-Type,Last-Modified</param-value>
15         </init-param>
16         <init-param>
17             <param-name>cors.exposedHeaders</param-name>
18             <param-value>Set-Cookie</param-value>
19         </init-param>
20         <init-param>
21             <param-name>cors.supportsCredentials</param-name>
22             <param-value>true</param-value>
23         </init-param>
24     </filter>
25     <filter-mapping>
26         <filter-name>CORS</filter-name>
27         <url-pattern>/*</url-pattern>
28     </filter-mapping>

3、若前台在header中添加了参数，则tomcate默认会过滤掉从而不走后台，例如在header中加入了参数NAME和PASS则在tomcate下的conf/web.xml中添加

解决方案：

    
      <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,NAME,PASS</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>
