spring,Tomcat @HandleTypes注释错误

tomcat

我正在运行一个相对简单的注释驱动的Spring配置的Web应用程序。我正在使用Java 1.6,Tomcat
7,并相信pom.xml中的适当依赖项,即jsp-api:2.2,javax.servlet-
api:3.0.1。尽管我的Web应用程序在运行时似乎没有任何问题,但我仍然不断收到以下错误。我确实在网上找到了对此错误的一个参考,它建议在我的web.xml文件中添加’metadata-
complete =“ true”’,这使@HandleTypes错误消失了,但阻止了我的应用正确构建自身。

任何建议/帮助将不胜感激。谢谢!

您应该确保war文件不包含Servlet API和JSP API jar,否则会遇到棘手的类加载问题。

但是,您仍然需要它们作为编译时依赖项。对于这种情况,Maven允许您使用scope声明这些依赖项provided

因此,确保jsp-api:2.2javax.servlet-api:3.0.1<scope>provided</scope>
