后台服务器端接受前端ajax post 跨域请求

首先配置web.xml文件过滤器

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

然后maven引入jar包

<!-- core跨域 -->
<dependency>
<groupId>com.thetransactioncompany</groupId>
<artifactId>cors-filter</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>com.thetransactioncompany</groupId>
<artifactId>java-property-utils</artifactId>
<version>1.9.1</version>
</dependency>
