配置Tomcat跨域设置

添加跨域jar包

• cor-filter-2.4.jar

这个可以去maven仓库下载相关jar包

将jar包放到tomcat的lib目录下，C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib

修改web.xml文件

文件在conf目录下，C:\Program Files\Apache Software Foundation\Tomcat 9.0\conf

添加如下配置代码

<!-- 提供跨域支持 -->
    <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>

    <filter-mapping>    
        <filter-name>CORS</filter-name>
