[1]CXF3.1整合Spring开发webservice——helloworld篇

Spring版本3.2.10

CXF版本3.1.1

项目采用MAVEN组织依赖jar

我这里是有parent的pom，为了简洁明了，我直接把所有的依赖都列一起了，所以都没version，反正上面已经写了版本

关于jar需要注意的是：spring使用的是xmlschema，而cxf使用的是xmlschema-core，因此最好显式地写在pom里面，否则会抛异常：java.lang.NoSuchMethodError:org.apache.ws.commons.schema.XmlSchemaCollection.read

另外，在最开始的配置过程中，遇到了unsupportedmajor.minorversion51.0的异常，也是之前没有遇到过的，后来查了一下发现一般都是因为jdk版本的问题，最后在apachecxf的官网上找到了答案：

ThecurrentplanisthatCXF3.1willnolongersupportJava6andwillrequireJava7ornewer.UsersarestronglyencouragedtostartmovingtoJava7.

好嘛，习惯1.6了……统统升级到1.7吧

保存pom，maven开始工作，duangduang开始向中央仓库拉各种文件，这个时间可以开始创建java类

//接口
@WebService
public interface IHelloWorldService {
    public void hello(String name);
}

//实现类
@WebService(endpointInterface="com.myproject.soa.cxf.IHelloWorldService")//endpointInterface是为了在实现多个接口情况下指明webservice的接口
@Component//这个是spring的注解
public class HelloWorldService implements IHelloWorldService {

    @Override
    public void hello(String name) {
        System.out.println("hello "+name);  
    }
}

接下来再配置spring

applicationContext-core.xml

<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.2.xsd  
           http://www.springframework.org/schema/context  
           http://www.springframework.org/schema/context/spring-context-3.2.xsd  
           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.2.xsd  
           http://www.springframework.org/schema/tx   
           http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
          ">

    <context:annotation-config />
    <context:component-scan base-package="com.myproject" />
</beans>

applicationContext-webservice.xml

<?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-3.2.xsd  
           http://cxf.apache.org/jaxws
           http://cxf.apache.org/schemas/jaxws.xsd
          ">

    <import resource="classpath:META-INF/cxf/cxf.xml" />
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
    <!--<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/> cxf 3以上的版本这条配置都去掉了-->

    <jaxws:endpoint id="helloworld" implementor="#helloWorldService" 
        address="/helloworld" />
</beans>

• implementor="#helloWorldService"的写法是使用spring托管的bean的名字,当然也可以写类名，不过太多字懒得敲，毕竟都和spring搞基了，就用spring的方式
• address是最后访问的路径

最后是web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext-*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 配置CXF框架的核心Servlet -->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

</web-app>

完成！

运行mvntomcat7:run

信息: Setting the server's publish address to be /helloword
六月 25, 2015 4:49:18 下午 org.apache.coyote.AbstractProtocol start
信息: Starting ProtocolHandler ["http-bio-8080"]

这时就可以访问http://localhost:8080/ws/helloworld?wsdl，正常的话可以看到一串xml，说明服务端已经完成
