Apache_CXF和Spring整合实现web_service.doc

CXF和spring整合实现webservice实例此文档旨在讲解Apache CXF和spring整合实现在Tomcat下发布web service的实例，以供学习参考。环境信息如下： JDK1.5.0 apache-tomcat-6.0.26 Spring2.5.6 apache-cxf-2.2.31、新建web项目使用Myeclipse6.5创建一个WEB工程cxfservice其中的WEB-INF/lib目录下的jar包为直接将apache-cxf-2.2.4.zip下载包中的apache-cxf-2.2.4lib目录下的全部的jar，在学习过程中这种办法是最简单的了。当然我们也可以用最少的Jar包来完成本实例的任务，首先要将cxf的依赖包加入，包括如下一些jar包：commons-logging-1.1.1.jar geronimo-activation_1.1_spec-1.0.2.jar (or Suns Activation jar) geronimo-annotation_1.0_spec-1.1.1.jar (JSR 250) geronimo-javamail_1.4_spec-1.6.jar (or Suns JavaMail jar) geronimo-servlet_2.5_spec-1.2.jar (or Suns Servlet jar) geronimo-ws-metadata_2.0_spec-1.1.2.jar (JSR 181) geronimo-jaxws_2.1_spec-1.0.jar (or Suns jaxws-api-2.1.jar) geronimo-stax-api_1.0_spec-1.0.1.jar (or other stax-api jar) jaxb-api-2.1.jar jaxb-impl-2.1.12.jar jetty-6.1.21.jar jetty-util-6.1.21.jar neethi-2.0.4.jar saaj-api-1.3.jar saaj-impl-1.3.2.jar wsdl4j-1.6.2.jar wstx-asl-3.2.8.jar XmlSchema-1.4.5.jar xml-resolver-1.2.jar 再就是Spring的包了，包括如下一些aopalliance-1.0.jar spring-core-2.5.5.jar spring-beans-2.5.5.jar spring-context-2.5.5.jar spring-web-2.5.5.jar 最后就是apache cxf本身的包了cxf-2.2.3.jar （2）配置文件说明applicationContext.xml文件的内容如下： services.xml文件的内容如下： web.xml文件的内容如下：view plaincopy to clipboardprint? cxfservice contextConfigLocation WEB-INF/classes/applicationContext.xml org.springframework.web.context.ContextLoaderListener CXFServlet org.apache.cxf.transport.servlet.CXFServlet CXFServlet /services/* index.html index.htm index.jsp default.html default.htm default.jsp （3）发布的HelloWord服务说明 要发布的HelloWorld服务的接口定义文件erfaces.HelloWorld： package erfaces; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; WebService public interface HelloWorld /* * 一个简单的方法,返回一个字符串 * * param hello * * return */ String say(String hello); /* * 稍微复杂一些的方法,传递一个对象给服务端处理 * * param user * return */ String sayUserName(WebParam(name = user) UserDTO user); /* * 最复杂的方法,返回一个List封装的对象集合 * * return */ public WebResult(partName = o) ListObject findUsers(); 要发布的HelloWorld服务的接口实现类erfaces.HelloWorldImpl：package erfaces; import java.util.ArrayList; import javax.jws.WebService; /* * WebService实现类. * * 使用WebService指向Interface定义类即可. */ WebService(endpointInterface = erfaces.HelloWorld) public class HelloWorldImpl implements HelloWorld public String sayUserName(UserDTO user) return hello + user.getName(); public String say(String hello) return hello + hello; public ListObject findUsers() ArrayList list = new ArrayList(); list.add(instancUser(1, lib); list.add(instancUser(2, mld); list.add(instancUser(3, lq); list.add(instancUser(4, gj); ListObject o = new ListObject(); o.setList(list); return o; private UserDTO instancUser(Integer id, String name) UserDTO user = new UserDTO(); user.setId(id); user.setName(name); return user; findUsers()接口返回的参数对象定义文件erfaces.ListObject：package erfaces; import java.util.ArrayList; import java.util.List; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlType; XmlAccessorType(XmlAccessType.FIELD) XmlType(name = listObject, propOrder = list ) public class ListObject XmlElement(nillable = true) protected List list; /* * Gets the value of the list property. * * * This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be * present inside the JAXB object. This is why there is not a set method for the list property. * * * For example, to add a new item, do as follows: * * * getList().add(newItem); * * * * * Objects of the following type(s) are allowed in the list link Object * * */ public List getList() if (list = null) list = new ArrayList(); return this.list; public void setList(ArrayList list) this.list = list; UserDTO instancUser(Integer id, String name)接口返回的对象定义文件erfaces.UserDTO：package erfaces; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlType; /* * Web Service传输User信息的DTO. * * 分离entity类与web service接口间的耦合，隔绝entity类的修改对接口的影响. 使用JAXB 2.0的annotation标注JAVA-XML映射，尽量使用默认约定. * */ XmlAccessorType(XmlAccessType.FIELD) XmlType(name = User) public class UserDTO protected Integer id; protected String name; public Integer getId() return id; public void setId(Integer value) id = value; public String getName() return name; public void setName(String value) name = value; （
