junit启动报错--初始化error

 java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=initialize], {ExactMatcher:fDisplayName=initialize(com.test.ProcessCoreServiceImpl)], {LeadingIdentifierMatcher:fClassName=com.test.ProcessCoreServiceImpl,fLeadingIdentifier=initialize]] from org.junit.internal.requests.ClassRequest@4e22b7dc

在例子中导入了junit变量。别的类里面的test标签启动好好的，包名也没有倒错。这真是诡异！！！
