春天，Tomcat @HandleTypes注释错误 [英] Spring, Tomcat @HandleTypes annotation error

问题描述

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消息.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.

I'm running a relatively simple annotation driven Spring configured web app. I'm using Java 1.6, Tomcat 7 and have I believe the appropriate dependencies in my pom.xml, i.e. jsp-api:2.2, javax.servlet-api:3.0.1. I continually get the error below although my webapp doesn't appear to have any problem while running. I did find one reference to this error online and it suggested adding 'metadata-complete="true"' to my web.xml file which made the @HandleTypes error go away but prevented my app from constructing itself properly.

任何建议/帮助将不胜感激. 谢谢！

Any suggestions/help would be greatly appreciated. Thanks!

推荐答案

您应确保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.

You should make sure that your war file doesn't contain Servlet API and JSP API jars, otherwise you'll get tricky classloading problems.

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

However, you still need them as compile-time dependencies. For this case Maven allows you to declare these dependencies with scope provided.

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