服务器端：

1、编写wsdl文件

<?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="MyServiceImplService"

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

    <!-- 定义类型 -->

  <wsdl:types>

    <xsd:schema targetNamespace="http://www.example.org/mywsdl/">

        <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"/>

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

        <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>

  <!-- 定义消息 -->

  <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:part>

  </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>

  <!-- 头消息 -->

  <wsdl:message name="licenseInfo">

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

  </wsdl:message>

  <!-- 定义port -->

  <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>

  <!-- 绑定服务 -->

  <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"/>

        <!-- 为add添加隐式的头信息 -->

        <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>

  <!-- 发布服务 -->

  <wsdl:service name="MyServiceImplService"><!-- 这里的名字必须和<wsdl:definitions里的name一致 -->

    <wsdl:port binding="tns:myServiceSOAP" name="MyServiceImplPort">

      <soap:address location="http://localhost:8989/ms"/>

    </wsdl:port>

  </wsdl:service>

</wsdl:definitions>

2、使用wsimport命令生成服务端接口类（IMyService.java）
备注:生成的其他文件都可以删除

在add方法的参数定义上加上

@WebParam(name="licenseInfo")String licenseInfo

3、编写服务接口的实现类MyServiceImpl.java

package org.example.mywsdl;

import javax.jws.WebService;

//这里必须制定wsdlLocation来约定参数等名称等

//endpointInterface可写也可不写，写它主要是用到自动生成的一些注解信息

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

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

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

        name="MyServiceImpl"

        )

public class MyServiceImpl implements IMyService {

    @Override

    public int add(int a, int b, String licenseInfo) {

        return a+b;

    }

    @Override

    public int divide(int num1, int num2) {

        return num1/num2;

    }

}

4、服务启动类

package org.example.mywsdl;

import javax.xml.ws.Endpoint;

public class RunService {

    public static void main(String[] args) {

        //这里的发布地址必须和wsdl中定义的一样

        Endpoint.publish("http://localhost:8989/ms", new MyServiceImpl());

    }

}

访问服务：http://localhost:8989/ms?wsdl

客户端直接用上面的地址生成即可，生成的wsdl文件即是我们编写的那个wsdl文件

    <wsdl:operation name="add">

      <wsdl:input>

        <soap:body use="literal"></soap:body>

        <!-- 为add添加隐式的头信息 -->

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

      </wsdl:input>

      <wsdl:output>

        <soap:body use="literal"></soap:body>

      </wsdl:output>

    </wsdl:operation>

    <wsdl:operation name="divide">

      <wsdl:input>

        <soap:body use="literal"></soap:body>

      </wsdl:input>

      <wsdl:output>

        <soap:body use="literal"></soap:body>

      </wsdl:output>

    </wsdl:operation>

  </wsdl:binding>

  <!-- 发布服务 -->

  <wsdl:service name="MyServiceImplService"><!-- 这里的名字必须和<wsdl:definitions里的name一致 -->

    <wsdl:port binding="tns:myServiceSOAP" name="MyServiceImplPort">

      <soap:address location="http://localhost:8989/ms"></soap:address>

    </wsdl:port>

  </wsdl:service>

</wsdl:definitions>

使用该wsdl生成客户端java代码后的add方法如下：

@WebMethod

    @WebResult(name = "addResult", targetNamespace = "")

    @RequestWrapper(localName = "add", targetNamespace = "http://www.example.org/mywsdl/", className = "com.ws04.Add")

    @ResponseWrapper(localName = "addResponse", targetNamespace = "http://www.example.org/mywsdl/", className = "com.ws04.AddResponse")

    public int add(@WebParam(name = "a", targetNamespace = "") int a,

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

此时方法的参数里没有看到有头信息参数的定义，调用该方法可以使用handler或者soap来编码传递头信息
