jav怎样实现对soapUI mockService功能的模拟,需要代码

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了jav怎样实现对soapUI mockService功能的模拟,需要代码相关的知识，希望对你有一定的参考价值。
参考技术A SoapUI在发送请求时，是直接以组装好的soap报文进行发送，而LR是使用web_service_call方法，从方法传入相应的参数，再由LR组装为soap报文后，再发往接口进行调用，因此LR在组装报文时，会有相应时间的耗费。LR脚本中创建的事务，就包含了这段组装报文的时间，因此响应时间会比SoapUI的响应时间更大。LR与SoapUI的差别应该还有更多，在此我尚未研究的更深入。

closeCamera（相当于onPause）和restartCamera（onResume）方法就不贴代码了。
Demo还有个问题，就是在低分辨率上面扫描区域出现了变形，我已经修改了，改天把代码打包发出来！可以加我QQ通知我！
先把代码贴出来：
