前言

  之前写过一篇整合ssm+cxf不过是soap webservice，另一种webservice的实现是Restful风格的。

   SOAP Webservice和Restful Webservice的使用，首先需要理解就是SOAP偏向于面向活动，有严格的规范和标准，包括安全，事务等各个方面的内容，同时SOAP强调操作方法和操作对象的分离，有WSDL文件规范和XSD文件分别对其定义。而REST强调面向资源，只要我们要操作的对象可以抽象为资源即可以使用REST架构风格。

开发环境

  Eclipse+jdk1.8+tomcat

所需jar包

  ssm框架的jar包和

                  

示例

web.xml

<!-- 配置cxf的核心控制器 -->        
    <servlet>   
        <servlet-name>CXFServlet</servlet-name>   
        <servlet-class>   
            org.apache.cxf.transport.servlet.CXFServlet    
        </servlet-class>   
        <load-on-startup>2</load-on-startup>   
    </servlet>   
   
   <!-- 所有来自/webservice/*的请求交给cxf处理 -->   
    <servlet-mapping>   
        <servlet-name>CXFServlet</servlet-name>   
        <url-pattern>/webservice/*</url-pattern>      
</servlet-mapping>

spring-dao.xml添加引用

service

@Path("/user")

serviceimpl

访问结果

访问http://localhost:8080/项目名/webservice/user/getUser?_type=json，返回Json

{"baseUser":[{"candyWalletAddress":"0x0686F106aD2194a7b012b18EC390F496042187B4","nickName":"测试","password":"123qwe","phoneNumber":18611112222,"userId":1},{"candyWalletAddress":"0x0686F106aD2194a7b012b18EC390F496042187B4","nickName":"ceshi","password":"ceshi1","phoneNumber":18831688664,"userId":2,"userName":"ceshi"}]}

或者http://localhost:8080/项目名/webservice/user/getUser?_type=xml，返回XML
