tomcat服务器跨域设置

应用于java的web项目首先需要导入两个包cors-filter 2.4 , java-property-utils 1.9.1<dependency>      <groupId>com.thetransactioncompany</groupId>      <artifactId>cors-filter</artifactId>      <version>2.4</version>  </dependency>  <dependency>      <groupId>com.thetransactioncompany</groupId>      <artifactId>java-property-utils</artifactId>      <version>1.9.1</version>  </dependency> 之后在web.xml中配置filter<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</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>服务器可以跨域
