在tomcat中部署geowebcache，存在跨域的时候，下载cors-filter-1.7.jar，java-property-utils-1.9.jar这两个jar包放入tomcat中，打开“apache-tomcat-9.0.73\webapps\geowebcache\WEB-INF”，然后找到 WEB-INF 下面的 web.xml 在filter标签末尾添加以下配置

<filter>         
    <filter-name>CORS</filter-name>  
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>  
    <init-param>

    </init-param>  
    <init-param>
