cxf 开发webservice 的两种实现方式

网上有许多开发webservice 的博客，不知道咋的我就是看不懂，所以在本人的努力下写这篇博客，希望对需要的人有用，还有许多人弄个破helloworld 程序收人金币本人黑恼火，所以发表这篇播客，cxf-servlet等配置在高版本的cxf中不需要引入，cxf有很多jar 包我也不知道干什么用的，所以这些jar 包是我根据别人的成果尝试后一步步试出来的，还有许多鬼儿子的弄个破jar 包在网上买，所以我打算用maven来搭建项目，学习的路是艰难的，现在网上许多博客好像和你打游击一样，谁也有是新手的时候，摸不着东西时候学习是痛苦的，我最恨的是妈的收保护费弄个破文档质量不知道咋样在网上卖，无耻！，虽然我没有多少C币。

首先需要了解一一下这两个基本的知识

JAX-WS：全称是JavaTM API forXML-Based Web Services
JAX-RS :全称是 JavaTM API forRESTful Web Services

搭建环境使用maven 导入jar包和配置web.xml

</project>

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <servlet>
  	<servlet-name>cxfServlet</servlet-name>
  	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  	<servlet-name>cxfServlet</servlet-name>
  	<url-pattern>/ws/*</url-pattern>
  </servlet-mapping>
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

配置spring 的核心配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
	http://cxf.apache.org/jaxws 
	http://cxf.apache.org/schemas/jaxws.xsd">
	<bean id="studentServiceImpl" class="com.huawei.it.service.StudentServiceImpl"></bean>
	<jaxws:endpoint id="studentService" implementor="#studentServiceImpl" address="/studentService" />
</beans>

1.创建接口就是在接口上面添加个@WebService

2.发布服务

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
	http://cxf.apache.org/jaxws 
	http://cxf.apache.org/schemas/jaxws.xsd">
	<bean id="studentServiceImpl" class="com.huawei.it.service.StudentServiceImpl"></bean>
	<jaxws:endpoint id="studentService" implementor="#studentServiceImpl" address="/studentService" />
</beans>

3.生成客户端代码，在path 中加入cxf bin目录的路径，-d 后面的是客户端生成的地址，后面wsdl文件的地址

wsdl2java -d ./test -client http://localhost:8082/ws/studentService?wsdl

4.进行调用，有个client的java文件，直接runAs 直接搞定

CXF开发Restful 服务

1.创建接口

public interface StudentService{
	@GET
	@Path(value = "/selectStudent")
	@Produces(MediaType.APPLICATION_JSON)
	List<StudentVO> selectStudent();
	
	@GET
	@Path(value ="/selectStudentBysNo")
	@Produces(MediaType.APPLICATION_JSON)	
	@Consumes({"application/json","application/xml"})
	StudentVO selectStudentVOBysNo(@QueryParam("sNo") String sNo);
	
	@GET
	@Path(value ="/selectStudentBysNo2/{sNo}")
	@Produces(MediaType.APPLICATION_JSON)	
	@Consumes({"application/json","application/xml"})
	StudentVO selectStudentVOBysNo2(@PathParam("sNo") String sNo);
}

2.发布服务

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:cxf="http://cxf.apache.org/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:security="http://www.springframework.org/schema/security"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
    http://www.springframework.org/schema/security 
    http://www.springframework.org/schema/security/spring-security.xsd">
    <jaxrs:server id="studentService" address="/studentService">
        <jaxrs:serviceBeans>
            <bean class="com.huawei.it.service.StudentServiceImpl" />
        </jaxrs:serviceBeans>
           <!-- 支持的协议 -->
        <jaxrs:extensionMappings> 
            <entry key="json" value="application/json" /> 
            <entry key="xml"  value="application/xml" /> 
        </jaxrs:extensionMappings> 
        <!-- 编码格式 -->
        <jaxrs:languageMappings>
               <entry key="en" value="en-gb"/>
        </jaxrs:languageMappings>
        <jaxrs:providers><!--特别注意2.5版本的是JSONProvider  而3.0版本后好像找不到这个类
        	<bean class="org.apache.cxf.jaxrs.provider.json.JsonMapObjectProvider"></bean>
        </jaxrs:providers>
    </jaxrs:server>

3.调用restful服务，rest服务是可以直接在浏览器中直接调用，但是请注意使用@PathParam和@QueryParam时候如果查询没有结果状态码是204，在调用时候不会出现第一种那样的wsdl ，这两个实现采用了不同的标准。
