隨著Web Service技術(shù)的發(fā)展，越來越多的應(yīng)用程序和開發(fā)項(xiàng)目中都廣泛使用到了Web Service技術(shù)，因此，在項(xiàng)目中開放Web Service接口是應(yīng)用Web Service技術(shù)必不可少的一步。本文我們就來看看在Java Web項(xiàng)目中開放Web Service接口實(shí)例。

下面是在Java Web項(xiàng)目中開放Web Service接口實(shí)例和過程：

1.引入需要的jar包

2.創(chuàng)建一個(gè)接口類IAddNumbers.java

[c-sharp] view plaincopy

package com.yjpeng.webservice;

public interface IAddNumbers {

public int addNumbers(int a, int b);

}

[c-sharp] view plaincopy

package com.yjpeng.webservice;

public interface IAddNumbers {

public int addNumbers(int a, int b);

}

3.創(chuàng)建一個(gè)AddNumberImpl.java實(shí)現(xiàn)IAddnumbers.java接口類

[c-sharp] view plaincopy

package com.yjpeng.webservice;

import javax.jws.WebService;

import com.sun.xml.ws.transport.http.servlet.WSServlet;

@WebService(targetNamespace="http://webservice.yjpeng.com", serviceName="AddNumberImplService",

portName="AddNumberImpl")

public class AddNumberImpl implements IAddNumbers {

public int addNumbers(int a, int b) {

return a + b;

}

}

[c-sharp] view plaincopy

package com.yjpeng.webservice;

import javax.jws.WebService;

import com.sun.xml.ws.transport.http.servlet.WSServlet;

@WebService(targetNamespace="http://webservice.yjpeng.com", serviceName="AddNumberImplService",

portName="AddNumberImpl")

public class AddNumberImpl implements IAddNumbers {

public int addNumbers(int a, int b) {

return a + b;

}

}

4.在WEN-INF目錄下創(chuàng)建一個(gè)sun-jaxws.xml文件

[c-sharp] view plaincopy

<endpoints version="2.0" <="" p="">

xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime">

<endpoint name="AddNumberImpl" <="" p="">

implementation="com.yjpeng.webservice.AddNumberImpl"

url-pattern="/addNumberImpl"/>

[c-sharp] view plaincopy

<endpoints version="2.0" <="" p="">

xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime">

<endpoint name="AddNumberImpl" <="" p="">

implementation="com.yjpeng.webservice.AddNumberImpl"

url-pattern="/addNumberImpl"/>

5.在web.xml文件中增加

[c-sharp] view plaincopy

AddNumberService

com.sun.xml.ws.transport.http.servlet.WSServlet

1

AddNumberService

/addNumberImpl

com.sun.xml.ws.transport.http.servlet.WSServletContextListener

[c-sharp] view plaincopy

AddNumberService

com.sun.xml.ws.transport.http.servlet.WSServlet

1

AddNumberService

/addNumberImpl

com.sun.xml.ws.transport.http.servlet.WSServletContextListener

6. 部署web項(xiàng)目啟動相應(yīng)的部署服務(wù)器。然后訪問http://localhost:8080/TestJaxWebService/addNumberImpl?wsdl 這樣每次啟動web服務(wù)器就開放了一個(gè)web service的接口。
