基于JAX-WS编写了RESTful的web服务端点。
http请求和响应的报文体都是xml数据,服务端分别对应了用JAXB注解的请求和响应类。
只实现了服务端的代码示例
客户端使用了Postman
http请求报文体的xml数据:
<?xml version="1.0" encoding="UTF-8"?>
<request>
<reqtype>01</reqtype>
<secret>test</secret>
<body>0858032316</body>
</request>
http响应报文体的xml数据:
<?xml version='1.0' encoding='UTF-8'?>
<response>
<body>15</body>
<flag>1</flag>
</response>
maven工程的pom.xml文件中增加如下依赖:
