tomcat如何跨域访问

1、首先打开访问，确认报错是因为跨域原因。如下图所示，Access-Control-Allow-Origin。

3、将上面的两个包放入 tomcat中的lib文件夹中。

5、添加如下代码到web.xml文件中web-app下。<filter> <filter-name>CORS&造婷用痃lt;/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>
