Eclipse动态Web项目 - MappingNotFoundException

[英]Eclipse dynamic web project - MappingNotFoundException

I have a Eclipse Dynamic Web Project which host a simple servlet and runs on Tomcat. 我有一个Eclipse动态Web项目,它托管一个简单的servlet并在Tomcat上运行。 I use Hibernate within - I have classes that map to database tables and hbm.xml files for them within my project. 我在内部使用Hibernate - 我的类在我的项目中有映射到数据库表和hbm.xml文件的类。 Everything works fine - I can use Hibernate from Servlet and modify database tables through classes. 一切正常 - 我可以使用Servlet中的Hibernate并通过类修改数据库表。 But now I want to move my "model" (Java classes for SQL tables and mapping files) to a separate Eclipse project so that I can use this "model" from other projects. 但现在我想将我的“模型”(SQL表和映射文件的Java类)移动到一个单独的Eclipse项目中,以便我可以使用其他项目中的“模型”。 After I specify a reference from my Web project to the "model" project, Eclipse can see the references and allows me using classes, but when I deploy and run the project on Tomcat, there are always errors like: 在我从Web项目到“模型”项目指定引用之后,Eclipse可以看到引用并允许我使用类,但是当我在Tomcat上部署和运行项目时,总会出现以下错误:

org.hibernate.MappingNotFoundException: resource: xxx/yyy/zzz/model/MyClassTable.hbm.xml not found org.hibernate.MappingNotFoundException:找不到资源:xxx / yyy / zzz / model / MyClassTable.hbm.xml

I suspect this is because I have to put classes for the model into WEB-INF directory, but I have no other idea how to do it than doing it manually. 我怀疑这是因为我必须将模型的类放入WEB-INF目录,但我不知道怎么做而不是手动操作。 What is the correct way to configure Web Project in that case? 在这种情况下配置Web项目的正确方法是什么?

It needs to be in /WEB-INF/classes , not in /WEB-INF . 它需要在/WEB-INF/classes ,而不是在/WEB-INF

That said, you are supposed to put class source files and any other resources like .hbm.xml files in the project's src folder. 也就是说,您应该将类​​源文件和任何其他资源(如.hbm.xml文件)放在项目的src文件夹中。 Eclispe will then "automagically" put them in the /WEB-INF/classes . 然后Eclispe将“自动”将它们放入/WEB-INF/classes Alternatively, if you want to detach the configuration files from the project, then just put it somewhere outside the project in a fixed path and add this path to the runtime classpath of the server. 或者,如果要从项目中分离配置文件,则只需将其放在项目外的某个固定路径中,并将此路径添加到服务器的运行时类路径中。 In Tomcat you can manage those paths in shared.loader property of /conf/catalina.properties . 在Tomcat中,您可以在管理这些路径shared.loader财产/conf/catalina.properties
