webservice（六）基于契约优先的wsdl文件生成webservice服务代码实例

首先是介绍整个流程

契约优先开发流程

1.先编写schema或者wsdl文件

2.根据这个文件生成一个客户端代码

3.编写实现类（在实现类上指定wsdlLocation）

4.发布服务

创建wsdl

1.在类路径META-INF下创建wsdl

2.新建wsdl并且编写文件

2.1编写type

2.2编写message

2.3编写portType指定接口和方法

2.4编写binding指定编码样式

2.5编写service（name要与命名空间名称一样）

3.根据名称生成服务器端代码

进入wsdl文件夹内用wsimport -d D:\sid\workspace_webservice\wsimport -keep mywsdl.wsdl

只留IMyService一个接口，其他的都删除

4.编写一个实现类实现接口

5.在实现类上指定wsdl的位置

指定targetNameSpace与接口的一样(可以不指定，但是需要自己重新添加方法的返回标注等)

@WebService(endpointInterface="org.example.mywsdl.IMyService",

targetNamespace="http://www.example.org/mywsdl/",

wsdlLocation="META-INF/wsdl/mywsdl.wsdl")

6.启动服务

然后在启动时候可以热修改，直接修改wsdl文件

7.执行服务器wsimport，生成客户端代码

wsimport -d D:\sid\workspace_webservice\wsimport -keep -verbose http://localhost:8989/ms?wsdl
8.加入header

wsdl文件中修改：

<!-- 定义头部信息 -->

<xsd:element name="licenseInfo" type="xsd:string"/>

<!-- 定义头信息 -->

<wsdl:message name="licenseInfo">

<wsdl:part name="licenseInfo" element="tns:licenseInfo"/>

</wsdl:message>

<!-- 在方法中加入头信息 -->

<soap:header use="literal" part="licenseInfo" message="tns:licenseInfo"/>

修改IMyService的add方法

public int add(

@WebParam(name = "a", targetNamespace = "")

int a,

@WebParam(name = "b", targetNamespace = "")

int b,

@WebParam(name = "licenseInfo", header=true)

String licenseInfo);

代码如下：

mywsdl.wsdl：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/mywsdl/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="mywsdl" targetNamespace="http://www.example.org/mywsdl/">
<wsdl:types>
<xsd:schema targetNamespace="http://www.example.org/mywsdl/">
<!-- 定义方法 -->
<xsd:element name="add" type="tns:add"/>
<xsd:element name="addResponse" type="tns:addResponse"/>
<xsd:element name="divide" type="tns:divide"/>
<xsd:element name="divideResponse" type="tns:divideResponse"/>
<!-- 定义头部信息 -->
<xsd:element name="licenseInfo" type="xsd:string"/>

<!-- 定义类型 -->
<xsd:complexType name="add">
<xsd:sequence>
<xsd:element name="a" type="xsd:int"/>
<xsd:element name="b" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="addResponse">
<xsd:sequence>
<xsd:element name="addResult" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="divide">
<xsd:sequence>
<xsd:element name="num1" type="xsd:int"/>
<xsd:element name="num2" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="divideResponse">
<xsd:sequence>
<xsd:element name="divideResult" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
</wsdl:types>

<wsdl:message name="add">
<wsdl:part name="add" element="tns:add"/>
</wsdl:message>
<wsdl:message name="addResponse">
<wsdl:part name="addResponse" element="tns:addResponse"/>
</wsdl:message>
<wsdl:message name="divide">
<wsdl:part name="divide" element="tns:divide"/>
</wsdl:message>
<wsdl:message name="divideResponse">
<wsdl:part name="divideResponse" element="tns:divideResponse"/>
</wsdl:message>
<!-- 定义头信息 -->
<wsdl:message name="licenseInfo">
<wsdl:part name="licenseInfo" element="tns:licenseInfo"/>
</wsdl:message>

<wsdl:portType name="IMyService">
<wsdl:operation name="add">
<wsdl:input message="tns:add"/>
<wsdl:output message="tns:addResponse"/>
</wsdl:operation>
<wsdl:operation name="divide">
<wsdl:input message="tns:divide"/>
<wsdl:output message="tns:divideResponse"/>
</wsdl:operation>
</wsdl:portType>

<wsdl:binding name="myServiceSOAP" type="tns:IMyService">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="add">
<wsdl:input>
<soap:body use="literal"/>
<!-- 加入头信息 -->
<soap:header use="literal" part="licenseInfo" message="tns:licenseInfo"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="divide">
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>

<wsdl:service name="MyServiceImplService">
<wsdl:port binding="tns:myServiceSOAP" name="MyServiceImplPort">
<soap:address location="http://localhost:8989/ms"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

只留IMyservice类，并进行修改：

package org.example.mywsdl;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;

/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2.4-b01
* Generated source version: 2.2
*
*/
@WebService(name = "IMyService",
targetNamespace = "http://www.example.org/mywsdl/")
public interface IMyService {

/**
*
* @param b
* @param a
* @return
*     returns int
*/
@WebMethod
@WebResult(name = "addResult", targetNamespace = "")
@RequestWrapper(localName = "add", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.Add")
@ResponseWrapper(localName = "addResponse", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.AddResponse")
public int add(
@WebParam(name = "a", targetNamespace = "")
int a,
@WebParam(name = "b", targetNamespace = "")
int b,
@WebParam(name = "licenseInfo", header=true)
String licenseInfo);

/**
*
* @param num2
* @param num1
* @return
*     returns int
*/
@WebMethod
@WebResult(name = "divideResult", targetNamespace = "")
@RequestWrapper(localName = "divide", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.Divide")
@ResponseWrapper(localName = "divideResponse", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.DivideResponse")
public int divide(
@WebParam(name = "num1", targetNamespace = "")
int num1,
@WebParam(name = "num2", targetNamespace = "")
int num2);

}

创建实现类之后发布服务

package org.example.mywsdl;

import javax.xml.ws.Endpoint;

public class MyServer {

public static void main(String[] args) {
//地址是在wsdl中编写的
Endpoint.publish("http://localhost:8989/ms", new MyServiceImpl());
}
}

根据服务器端生成客户端代码后：

wsimport -d D:\sid\workspace_webservice\wsimport -keep -verbose http://localhost:8989/ms?wsdl
加入测试类：

package org.example.test;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;

public class Test {

public static void main(String[] args) {
String ns = "http://www.example.org/mywsdl/";
try {
QName name = new QName(ns,"MyServiceImplService");
URL url = new URL("http://localhost:8989/ms?wsdl");
//			MyServiceImplService mis = new MyServiceImplService(url,name);
//			IMyService ms = mis.getMyServiceImplPort();
//			System.out.println(ms.divide(19, 2));
//使用soap来传递消息
Service service = Service.create(url,name);
QName pname = new QName(ns,"MyServiceImplPort");
Dispatch<SOAPMessage> dispatch  = service.createDispatch(pname, SOAPMessage.class, Service.Mode.MESSAGE);
SOAPMessage msg = MessageFactory.newInstance().createMessage();
SOAPEnvelope enve = msg.getSOAPPart().getEnvelope();
SOAPHeader header = enve.getHeader();
SOAPBody body = enve.getBody();
if (header==null) {
header = enve.addHeader();
}
QName hname = new QName(ns,"licenseInfo","ns");
header.addHeaderElement(hname).setValue("sssssssss");
QName bname = new QName(ns,"add","ns");
SOAPBodyElement ele = body.addBodyElement(bname);
ele.addChildElement("a").setValue("12");
ele.addChildElement("b").setValue("12");

msg.writeTo(System.out);
System.out.println("\n invoking。。。。。。。。");

SOAPMessage rep = dispatch.invoke(msg);
rep.writeTo(System.out);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (SOAPException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

}
