初学activiti，在参考编写流程定义文件后，部署到activiti后，根据流程名称查询流程信息，始终报错：
org.activiti.engine.ActivitiObjectNotFoundException: no processes deployed with key 'helloword' at org.activiti.engine.impl.persistence.deploy.DeploymentManager.findDeployedLatestProcessDefinitionByKey(DeploymentManager.java:125) at org.activiti.engine.impl.cmd.StartProcessInstanceCmd.execute(StartProcessInstanceCmd.java:79) at org.activiti.engine.impl.cmd.StartProcessInstanceCmd.execute(StartProcessInstanceCmd.java:37) at org.activiti.engine.impl.interceptor.CommandInvoker.execute(CommandInvoker.java:24) at org.activiti.engine.impl.interceptor.CommandContextInterceptor.execute(CommandContextInterceptor.java:57) at org.activiti.engine.impl.interceptor.LogInterceptor.execute(LogInterceptor.java:37) at org.activiti.engine.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:40) at org.activiti.engine.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:35) at org.activiti.engine.impl.RuntimeServiceImpl.startProcessInstanceByKey(RuntimeServiceImpl.java:69) at com.feng.test02.Test02Main.start(Test02Main.java:58) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)
代码如下：
单元测试类：
@Before
public void before(){
//创建流程引擎
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:com/feng/test02/activiti-config.xml");
ProcessEngineConfiguration config = ctx.getBean( ProcessEngineConfiguration.class);
config.setProcessEngineName("测试流程引擎");
engine = config.buildProcessEngine();
}
@Test
public void build() throws Exception{
//部署流程定义文件
RepositoryService repositoryService = engine.getRepositoryService();
Deployment deployment = repositoryService.createDeployment().addClasspathResource("com/feng/test02/helloword.bpmn.xml").name("helloword").deploy();
//验证已部署流程定义
System.out.println("流程部署ID:"+ deployment.getId());
System.out.println("流程部署Name:"+deployment.getName());
}
/**
* 启动流程实例
*/
@Test
public void start(){
// 启动并获取流程实例
ProcessInstance processInstance= engine.getRuntimeService() // 运行时流程实例Service
.startProcessInstanceByKey("helloword"); // 流程定义表的KEY字段值
System.out.println("流程实例ID:"+processInstance.getId());
System.out.println("流程定义ID:"+processInstance.getProcessDefinitionId());
}
流程定义xml如下：

将流程定义文件名称的bmpn改为 bmpn20即可。
