5.Servlet跨域

Servlet跨域

1.添加依赖

• 添加处理跨域的依赖

<dependency>
     <groupId>com.thetransactioncompany</groupId>
     <artifactId>cors-filter</artifactId>
     <version>2.9.1</version>
</dependency>

2.编辑配置

• 在web.xml中添加过滤器

<!--配置跨域过滤器--> 
<filter>
    <filter-name>corsFilter</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>corsFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
