用myEclipse搭建hibernate框架后,有时搞乱了某些东西后,又想重新加载Hibernate包,但此时 add hibernate capabilities 功能菜单竟然是灰色的,不可用,尤其是初学的朋友往往要重建web项目,一切都要重新来过。
其实大可不必这么做。有个简单的方法可以解决这个问题:
切换到java的导航试图,在项目的根目录下又个项目配置文件:".project",打开后如下代码所示。
<?xml version="1.0" encoding="UTF-8"?> <projectDescription> <name>CourseMS</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.WebClasspathBuilder</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.J2EEProjectValidator</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.DeploymentDescriptorValidator</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>org.eclipse.wst.validation.validationbuilder</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>com.genuitec.eclipse.hibernate.HibernateBuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>com.genuitec.eclipse.hibernate.hibernatenature</nature> <nature>com.genuitec.eclipse.j2eedt.core.webnature</nature> <nature>org.eclipse.jdt.core.javanature</nature> <nature>org.eclipse.wst.jsdt.core.jsNature</nature> </natures> </projectDescription>
一般在最下方有:
<buildCommand> <name>com.genuitec.eclipse.hibernate.HibernateBuilder</name> <arguments> </arguments> </buildCommand>
和
<nature>com.genuitec.eclipse.hibernate.hibernatenature</nature>
将这两段删除即可
