无法在jbpm java中创建RuntimeManager

Question

我正在尝试使用PerProcessInstanceRuntimeManager创建RuntimeManager

ReleaseId releaseId = new ReleaseIdImpl("com.myorg.app.bpm", "myproject", "1.0");
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.domain");
RuntimeEnvironmentBuilder builder = RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder(releaseId).entityManagerFactory(emf).userGroupCallback(new CustomUserCallBack());
RuntimeManager runtimeManager = RuntimeManagerFactory.Factory.get().newPerProcessInstanceRuntimeManager(builder.get(), "com.sample:example:1.0");

我得到的错误是：

java.lang.IllegalArgumentException：找不到命名查询：org.jbpm.runtime.manager.impl.mapper.JPAMapper.findKSessionToInit（JPAMapper.java：org.hibernate.ejb.AbstractEntityManagerImpl.createNamedQuery（AbstractEntityManagerImpl.java:636）处的FindKSessionToInit： 205），位于org.jbpm.runtime.manager.impl.PerProcessInstanceRuntimeManager.init（PerProcessInstanceRuntimeManager.java:322），位于org.jbpm.runtime.manager.impl.RuntimeManagerFactoryImpl.newPerProcessInstanceRuntimeManager（RuntimeManagerFactoryImpl.java:97）

请提出一些解决方案

您是否有机会使用自己的persistence.xml？ 此查询在ContextMappingInfo类中定义： https : //github.com/droolsjbpm/jbpm/blob/master/jbpm-runtime-manager/src/main/java/org/jbpm/runtime/manager/impl/jpa/ContextMappingInfo .java＃L48

此类应在您的persistence.xml中： https : //github.com/droolsjbpm/jbpm/blob/master/jbpm-installer/db/jbpm-persistence-JPA2.xml#L55
