apache CXF＋SpringでWebサービス作成時にWSDLを分離しない方法

よくあることだと思うけど、最近仕事でWebサービスのスタブが必要だったのでapache CXF＋SpringでスタブWebサービスを作成してた。
それぞれのクラスや設定ファイルはこんな感じ。

◆サービスインタフェースクラス

package org.ws.sample.stub.service;

import javax.jws.WebService;

@WebService
public interface StubService {
	public String stubMethod(String data);
}

◆サービスクラス

package org.ws.sample.stub.service.impl;

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

import org.ws.sample.stub.service.StubService;

@WebService(
		serviceName = "StubService", 
		endpointInterface = "org.ws.sample.stub.service.StubService", 
		portName = "StubServicePort")
@SOAPBinding(
		style=Style.DOCUMENT,
		use=Use.LITERAL,
		parameterStyle=ParameterStyle.BARE
		)
public class StubServiceImpl implements StubService {
	public String stubMethod(String data) {
		return data;
	}
}

ちなみにMavenには「maven-jetty-plugin」を導入して

mvn jetty:run

でこのWebサービスが起動するようにしている。

そしてここで少し問題が発生。
この設定ではサービス定義（WSDL）はこんな感じになる。

<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="StubService" targetNamespace="http://impl.service.stub.sample.ws.org/" xmlns:ns1="http://service.stub.sample.ws.org/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.stub.sample.ws.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:import location="http://localhost:8888/webapp/ws/StubService?wsdl=StubService.wsdl" namespace="http://service.stub.sample.ws.org/">
    </wsdl:import>
  <wsdl:binding name="StubServiceSoapBinding" type="ns1:StubService">
　：

なにが問題かというと、

<wsdl:import location="http://localhost:8888/webapp ・・・

の部分。
デフォルトの設定ではcomplexTypeとかportTypeとかが別WSDLへ分離されて定義されてしまうようだ。

これ自体は動作上何の問題もないんだが、システム検証の関係上、１つのWSDL統合したかった。
どうにか出来ないものかと考えていたところ
http://www.mail-archive.com/cxf-user@incubator.apache.org/msg04545.html
を発見、

If all the namespaces are the same, CXF should generate a WSDL that
doesn't use any wsdl imports. 

For the most part, add @WebService(targetNamespace = ".....")
annotations to both the SEI interface and the implementation making sure
the 
targetNamespace is the same for both.   That should allow both the 
logical stuff (interface/portType) and the physical
(impl/service/binding) to be in the same namespace and thus the same
wsdl.

との記述があった。
つまり、Webサービスインタフェースとその実装クラスに同じ「targetNamespace="....."」を指定すれば同じWSDLに定義が吐かれるだろうとのこと。

これを見習って、

◆サービスインタフェースクラス

package org.ws.sample.stub.service;

import javax.jws.WebService;

@WebService(
		serviceName = "StubService", 
		targetNamespace="http://impl.service.stub.sample.ws.org/")
public interface StubService {
	public String stubMethod(String data);
}

◆サービスクラス

package org.ws.sample.stub.service.impl;

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

import org.ws.sample.stub.service.StubService;

@WebService(
		serviceName = "StubService", 
		portName = "StubServicePort",
		targetNamespace="http://impl.service.stub.sample.ws.org/")
@SOAPBinding(
		style=Style.DOCUMENT,
		use=Use.LITERAL,
		parameterStyle=ParameterStyle.BARE
		)
public class StubServiceImpl implements StubService {
	public String stubMethod(String data) {
		return data;
	}
}

と修正した。

するとWSDLは

<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="StubService" targetNamespace="http://impl.service.stub.sample.ws.org/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.stub.sample.ws.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:types>
<xs:schema elementFormDefault="unqualified" targetNamespace="http://impl.service.stub.sample.ws.org/" version="1.0" xmlns:tns="http://impl.service.stub.sample.ws.org/" xmlns:xs="http://www.w3.org/2001/XMLSchema">
　：

のように無事１つに統合された。
