SSM-跨域問題配置

我用的是阿里雲倉庫地址：
其他的可能各有版本不同，自行查證！
在pox.xml文件引用

<!-- 跨域過濾器相關 -->
<dependency>
    <groupId>com.thetransactioncompany</groupId>
    <artifactId>java-property-utils</artifactId>
    <version>1.9.1</version>
</dependency>
<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.6.2</version>
</dependency>
<dependency>
    <groupId>com.thetransactioncompany</groupId>
    <artifactId>cors-filter</artifactId>
    <version>2.5</version>
</dependency>
<!-- 跨域過濾器相關 -->

然後在web.xml文件添加配置

 <filter>  
       <description>跨域過濾器</description>  
       <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>

到此應該是可以解決了！
