grails配置tomcat-->server.xml Context>path>docBase

在grails-->scripts创建一个_Events.groovy，注销系统自动生成的代码加入以下代码

import org.apache.catalina.loader.WebappLoadereventConfigureTomcat = {tomcat ->    def imagesContextRoot = '/examphoto'    File appDir = new File('d:/examphoto');    context = tomcat.addWebapp(imagesContextRoot, appDir.getAbsolutePath());    context.reloadable = true    WebappLoader loader = new WebappLoader(tomcat.class.classLoader)    context.loader = loader}
