\[activiti6\]几个报错解决

# 运行test webservice #

org.activiti.engine.ActivitiException: no default process engine available
    	at org.activiti.engine.impl.test.PluggableActivitiTestCase.initializeProcessEngine

先不使用PluggableActivitiTestCase，还是直接用srpingboot的test（原来放在test里不行，放src）。

# Item reference is invalid: not found #

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine': 
    FactoryBean threw exception on object creation; nested exception is org.activiti.engine.ActivitiException: Errors while parsing:
    [Validation set: 'activiti-executable-process' | Problem: 'activiti-message-invalid-item-ref'] : 
    Item reference is invalid: not found - [Extra info : ] ( line: 72, column: 54)

看官网有tns:，直接增加看看：不行。

> Caused by: org.xml.sax.SAXParseException; lineNumber: 50; columnNumber: 57; UndeclaredPrefix: 无法将 'tns:createMpcItem' 解析为限定名: 未声明前缀 'tns'。

*  移动前面定义。也不行。因为xml不区分这个。
 *  看源代码！`MessageValidator.java`
 *  意思是bpmn文件里，找不到itemRef的定义。
 *  itemRef="[http://www.activiti.org/test:createMpcItem"也不行。][http_www.activiti.org_test_createMpcItem]
 *  试试xmlns:tns="[http://www.activiti.org/test][http_www.activiti.org_test]"
 *  可以了！

# Could not find importer for type [http://schemas.xmlsoap.org/wsdl/][http_schemas.xmlsoap.org_wsdl] #

org.activiti.engine.ActivitiException: Could not find importer for type http://schemas.xmlsoap.org/wsdl/
    	at org.activiti.engine.impl.bpmn.behavior.WebServiceActivityBehavior.fillImporterInfo

*  看源代码fillImporterInfo。
 *  必须写[http://schemas.xmlsoap.org/wsdl/，把异常隐藏了，晕。][http_schemas.xmlsoap.org_wsdl 1]
 *  CxfWSDLImporter.java是cxf的，难道没引入jar的缘故？？？
 *  wsdlImporterClass = Class.forName("org.activiti.engine.impl.webservice.CxfWSDLImporter", true, Thread.currentThread().getContextClassLoader());
 *  知道了，是的。
 *  activiti-cxf，maven库里是unknown，要指定版本！
 *  解决了！！！我的天，搞了一下午。
