maven+spring+cxf编写web service

1.创建项目

mvn archetype:generate -DarchetypeCatalog=Internal

选择19，创建web项目

2.生成eclipse项目，参见文章
3.修改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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>Archetype Created Web Application</display-name>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 设置Spring容器加载配置文件路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>CXFService</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>CXFService</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>
</web-app>

4.创建webservice接口

package com.sysware.demo.app.service.inf;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import com.sysware.demo.app.model.RetInfo;

@WebService
public interface IGetInfoService
{
    @WebMethod(operationName = "add")
    @WebResult(name = "result")
    public int add(@WebParam(name = "num1") int num1,
            @WebParam(name = "num2") int num2);

    @WebMethod(operationName = "getRetInfo")
    @WebResult(name = "result")
    public RetInfo getRetInfo(@WebParam(name = "name") String name, @WebParam(name = "age") int age);
}

5.创建webservice实现类

package com.sysware.demo.app.service.impl;

import javax.jws.WebService;

import com.sysware.demo.app.model.RetInfo;
import com.sysware.demo.app.service.inf.IGetInfoService;

@WebService(endpointInterface = "com.sysware.demo.app.service.inf.IGetInfoService")
public class GetInfoServiceImpl implements IGetInfoService
{

    @Override
    public int add(int num1, int num2)
    {
        return num1 + num2;
    }

    @Override
    public RetInfo getRetInfo(String name, int age)
    {
        RetInfo retInfo = new RetInfo();
        retInfo.setAge(age);
        retInfo.setName(name);
        return retInfo;
    }

}

6.返回对象

package com.sysware.demo.app.model;

public class RetInfo
{
    private String name;
    private int age;
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }
    public int getAge()
    {
        return age;
    }
    public void setAge(int age)
    {
        this.age = age;
    }
}

7.创建bean文件applicationContext.xml在WEB-INF目录下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.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-xml.xml"/>
    <bean id="getInfoServiceImpl" class="com.sysware.demo.app.service.impl.GetInfoServiceImpl"></bean>
    <jaxws:endpoint id="getInfoService" implementor="#getInfoServiceImpl" address="/getInfoService"></jaxws:endpoint>
</beans>

8.修改pom文件

<span style="white-space:pre">  </span><modelVersion>4.0.0</modelVersion>
<span style="white-space:pre">  </span><groupId>com.sysware.demo</groupId>
<span style="white-space:pre">  </span><artifactId>mvncxfdemo</artifactId>

        </dependency>
        <dependency>

                </configuration>
            </plugin>
        </plugins>
    </build>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

9.运行

mvn clean jetty:run-war

10.或者实现接口修改为

package com.sysware.demo.app.service.impl;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import com.sysware.demo.app.model.RetInfo;

@WebService
public class GetInfoServiceImpl
{

    @WebMethod(operationName = "add")
    @WebResult(name = "result")
    public int add(@WebParam(name = "num1") int num1,
            @WebParam(name = "num2") int num2)
    {
        return num1 + num2;
    }

    @WebMethod(operationName = "getRetInfo")
    @WebResult(name = "result")
    public RetInfo getRetInfo(@WebParam(name = "name") String name, @WebParam(name = "age") int age)
    {
        RetInfo retInfo = new RetInfo();
        retInfo.setAge(age);
        retInfo.setName(name);
        return retInfo;
    }

}

由于客户端用gsoap，如果两个service在同一个目录下，将导致错误，因为两个targetNamespace相同

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://userlist.user.webservice.service.cms.ivideo.sysware.com/" elementFormDefault="unqualified" targetNamespace="http://userlist.user.webservice.service.cms.ivideo.sysware.com/" version="1.0">

为了保证两个service不在一个target里面，建议每个package下只有一个webservice
