webservice学习 由服务接口代码生成wsdl文件

1、下载axis2-1.6.2，包含biz.zip 和war.zip（建议去apache官网下载）

2、解压axis2-1.6.2-bin.zip包，环境变量添加AXIS2_HOME，注意名字不能写错，同时要检查一下环境变量是否有JAVA_HOME，axis2的工具运行时，会依赖JAVA_HOME。

3、eclipse上新建java工程，定义bean类，service接口，如下演示代码，包含Student和StudentService两个类：

package com.hy.bean;

public class Student {

	private String id;
	private String number;
	private String name;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getNumber() {
		return number;
	}

	public void setNumber(String number) {
		this.number = number;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

 

package com.hy.service;

import com.hy.bean.Student;

public interface StudentService {

	public void saveStudent(Student stu);
}

4、命令行进入该工程的classes根目录（build或是bin目录，看具体的工程设置），键入命令：%AXIS2_HOME%\bin\java2wsdl -cp . -cn com.hy.service.StudentService -of Student.wsdl

5、命令执行成功后，就能在当前的执行目录下看到Student.wsdl文件，如此wsdl文件就生成了，我们看一来生成的wsdl文件：

<?xml version="1.0" encoding="UTF-8"?>

    <wsdl:message name="saveStudentRequest">

                <mime:content type="application/xml" part="parameters"/>
            </wsdl:input>
        </wsdl:operation>
    </wsdl:binding>
    <wsdl:service name="StudentService">
        <wsdl:port name="StudentServiceHttpSoap11Endpoint" binding="ns:StudentServiceSoap11Binding">
            <soap:address location="http://localhost:8080/axis2/services/StudentService"/>
        </wsdl:port>
        <wsdl:port name="StudentServiceHttpSoap12Endpoint" binding="ns:StudentServiceSoap12Binding">
            <soap12:address location="http://localhost:8080/axis2/services/StudentService"/>
        </wsdl:port>
        <wsdl:port name="StudentServiceHttpEndpoint" binding="ns:StudentServiceHttpBinding">
            <http:address location="http://localhost:8080/axis2/services/StudentService"/>
        </wsdl:port>
    </wsdl:service>
</wsdl:definitions>

可能我们对wsdl文件结构还不是很了解，我们可以通过比对wsdl文件内容和服务接口代码来了解一些信息。例如：

            <xs:complexType name="Student">
                <xs:sequence>
                    <xs:element minOccurs="0" name="id" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="name" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="number" nillable="true" type="xs:string"/>
                </xs:sequence>
            </xs:complexType>

从这段xml内容我们可以看到Student, id,name,number字样，这个对应的就是咱们的Student 类。

其实wsdl描述的就是服务接口信息，我们定义的bean类，service接口，都会在这个文件中得到体现。我们可以通过查资料，看案例去更多地了解wsdl的知识。
