關於服務器跨域問題（使用cors解決）

1.配置cors依賴

pom中加入

<dependency>
<groupId>com.thetransactioncompany</groupId>
<artifactId>cors-filter</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>com.thetransactioncompany</groupId>
<artifactId>java-property-utils</artifactId>
<version>1.9</version>
</dependency>

 

2.配置filter

web.xml中加入如下配置：（必須把filter放到最上面，否則會不起作用）

<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>*</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>

配置完成，重啟，跨域問題就解決了！！
