今天和你们分享使用 web方式发布 webService 服务端、客户端java

1.首先建立一个web工程（增长Maven依赖）web

2.增长Maven依赖包，以下：spring

<!-- spring core -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>2.5.5</version>
        </dependency>
        <!-- spring beans -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>2.5.5</version>
        </dependency>
        <!-- spring context -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>2.5.5</version>
        </dependency>
        <!-- spring web -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>2.5.5</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.1</version>
        </dependency>
        <dependency>
            <groupId>javax.xml</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.1</version>
            <type>pom</type>
        </dependency>
        <dependency>
            <groupId>javax.xml</groupId>
            <artifactId>jaxb-impl</artifactId>
            <version>2.1</version>
        </dependency>
        <dependency>
            <groupId>xfire</groupId>
            <artifactId>saaj-api</artifactId>
            <version>1.3</version>
        </dependency>
        <dependency>
            <groupId>xfire</groupId>
            <artifactId>saaj-impl</artifactId>
            <version>1.3</version>
        </dependency>
        <dependency>
            <groupId>wsdl4j</groupId>
            <artifactId>wsdl4j</artifactId>
            <version>1.6.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http-jetty</artifactId>
            <version>2.2.3</version>
        </dependency>

3. 编写HelloWorld 接口类代码以下：apache

package net.cc.service;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
 * @author test
 * @create 2013-11-26下午10:21:13
 */
@WebService
public interface HelloWorld {
    String sayHello(@WebParam(name = "userName") String userName);
}

说明：api

@webService 说明这是一个webServicetomcat

@webParam 说明参数名称frontend

4. 编写实现类以下：ide

package net.cc.service;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
 * @author test
 * @create 2013-11-26下午10:22:53
 */
@WebService(serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {
    @Override
    public String sayHello(@WebParam(name = "userName") String userName) {
        // TODO Auto-generated method stub
        System.out.println("客户端提交信息： " + userName);
        return "say Hello " + userName;
    }
}

说明：spa

@webService（serviceName ＝ “HelloWorld”）让Apache cxf知道是哪一个接口来建立的WSDL.net

5. 编写spring xml文件以下：

<?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.xsd
        http://cxf.apache.org/jaxws
        http://cxf.apache.org/schemas/jaxws.xsd">
    <jaxws:endpoint id="ProjectManager" implementor="net.cc.service.HelloWorldImpl"
        address="http://192.168.1.105:7890/HelloWorld" />
</beans>

说明：

implementor 表示实现类路径

address 表示须要发布的wsdl地址

6.编写 myListener 类以下：

package net.cc.servlet;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
 * @author test
 * @create 2013-11-26下午10:41:53
 */
public class myListener implements ServletContextListener {
    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        // TODO Auto-generated method stub
    }
    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        // TODO Auto-generated method stub
        System.out.println("启动Tomcat...");
        ClassPathXmlApplicationContext act = new ClassPathXmlApplicationContext(
                "/net/cc/service/spring-beans.xml");
    }
}

说明：

实现 ServletContextListener 目的是为了在Tomcat启动时自动加载

使用 ClassPathXmlApplicationContext 去加载刚才写的 spring-beans.xml 文件

7. 在当前项目中web.xml文件增长以下代码：

<listener>
    <listener-class>net.cc.servlet.myListener</listener-class>
</listener>

说明：

实现 ServletContextListener 接口的类路径
