CXF学习笔记---让通过参数传递数据

整整折腾了3天终于通过CXF进行参数传递了。CXF的文档和sample都是存在问题的。这么一些简单的常用内容，硬是找不着。opensource的弊病。
目地：
通过webservice传递值以及错误信息。true：取result值，false：取errorNum和errorMsg

【Server】
1、Interface

@WebService
public interface DatasetExcute {
//	List<TableDataInfo> excuteSql(String sql);
	String excuteSqlWithReturnXml(String sql);
//	Document excuteSqlWithReturnDoc(String sql);
	public boolean excuteSqlWithReturnDocAndMsg(
			@WebParam(name = "excuteSql",  header = true,mode = WebParam.Mode.IN)
			String sql, @WebParam(name = "excuteResult", targetNamespace = "",mode = WebParam.Mode.OUT)
			javax.xml.ws.Holder<java.lang.String> result, @WebParam(name = "errorNumber", targetNamespace = "", mode = WebParam.Mode.OUT)
			javax.xml.ws.Holder<java.lang.String> errorNumber, @WebParam(name = "errorMsg", targetNamespace = "", mode = WebParam.Mode.OUT)
			javax.xml.ws.Holder<java.lang.String> errorMsg);
}

2.impletement文件

@WebService(endpointInterface = "com.tnt.mms.webservice.DatasetExcute")
public class DatasetExcuteImpl implements DatasetExcute {
	private NativeDAO nativeDAO;

	public void setNativeDAO(NativeDAO nativeDAO) {
		this.nativeDAO = nativeDAO;
	}

	//
	// public List<TableDataInfo> excuteSql(String sql) {
	//		  
	//
	// List<TableDataInfo> ret=nativeDAO.bulkOperationWithReturnAndFields(sql);
	// return ret;
	//
	// }

	public String excuteSqlWithReturnXml(String sql) {
		String xmlRet = nativeDAO.bulkOperationWithReturnXml(sql);
		return xmlRet;
	}

	public Document excuteSqlWithReturnDoc(String sql) {
		Document xmlRet = nativeDAO.bulkOperationWithReturnDoc(sql);
		return xmlRet;
	}

	public boolean excuteSqlWithReturnDocAndMsg(String sql,
			javax.xml.ws.Holder<java.lang.String> result,
			javax.xml.ws.Holder<java.lang.String> errorNumber,
			javax.xml.ws.Holder<java.lang.String> errorMsg) {
		boolean blnReturn = false;
		try {
			result.value = nativeDAO.bulkOperationWithReturnXml(sql);

			blnReturn = true;

		} catch (Exception e) {
			errorNumber.value = "ES0001";
			errorMsg.value = "Database Error!";
		}
		return blnReturn;
	}

}

3、描述文件

	<jaxws:endpoint id="DatasetExcute"
		implementorClass="com.tnt.mms.webservice.DatasetExcuteImpl"
		implementor="#DatasetExcuteImpl" address="/DatasetExcute">
		<!-- 用参数传递，就不要用aegis
		<jaxws:serviceFactory>
			<ref bean="jaxws-and-aegis-service-factory" />
		</jaxws:serviceFactory>-->
	</jaxws:endpoint>

【client test】

public final class Client_DbExcute {

	private Client_DbExcute() {
	}

	public static void main(String args[]) throws Exception {
		// START SNIPPET: client
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
				new String[] { "com/tnt/mms/webservice/client/client-DbExcute.xml" });
		try {
			DatasetExcute client = (DatasetExcute) context.getBean("client");
			// List<TableDataInfo> list=null;
			// list = client.excuteSql("select* from vendor");
			// String list = client.excuteSqlWithReturnXml("select* from vendor
			// where vendorID like '111%'");
			// Document list = client
			// .excuteSqlWithReturnDoc("select* from vendor where vendorID like
			// '111%'");.
			StringBuffer sql = new StringBuffer();
			sql
					.append("if object_id('tempdb..#UOM150232076') is not null begin");
			sql.append(" drop table 	#UOM150232076    ");
			sql.append(" end");

			sql.append("  begin tran");

			sql.append(" select distinct itemid, pack, EngUOM as UOM,");
			sql
					.append("coalesce(ManualWeight,0) as ManualWeight, coalesce(GST,0) as GST,");
			sql
					.append("        ' ' as flag, getdate() as chgtime, '754410' as chgby");
			sql.append(" into #UOM150232076");
			sql.append("  from [tntdb150].RIS_test.dbo.Pos");
			sql.append("  where itemid = '663247'");
			sql.append(" order by pack");

			sql.append(" if @@ROWCOUNT=0");
			sql
					.append("  insert into #UOM150232076 (  itemid , pack          ,  UOM,");
			sql.append("ManualWeight, GST, flag,   chgtime,      chgby)");
			sql.append("           values('663247', 1000 * 0 + 1.0, 'ea',");
			sql.append("0,   0,  ' ', getdate(), '754410')");

			sql.append(" select * from #UOM150232076");

			sql.append(" if @@error <> 0");
			sql.append("    rollback tran");
			sql.append(" else");
			sql.append("   commit tran");

//			Document list = client
//					.excuteSqlWithReturnDoc("select* from vendor where vendorID='10118'");
		
	        
//			Document list = client
//			.excuteSqlWithReturnDoc(sql.toString());
//			list.getFirstChild().getTextContent();
//			XmlUtil.save(list, "c:/test.xml");
			
//			String list1= "";
//			String  errorNumber="", errorMsg = "";
			Holder<String> list1=new Holder<String>();
			Holder<String> errorNumber=new Holder<String>();
			Holder<String> errorMsg=new Holder<String>();
		
		boolean ret=client.excuteSqlWithReturnDocAndMsg("select * from vendor where vendorID like '111%'", list1, errorNumber, errorMsg);
		if(ret)
		{
			System.out.println("result: "
					+ list1+":"+list1.value);
			XmlUtil.writeXml(list1.value, "c:/ls.xml");
		}
		else
		{
			System.out.println("Error: "
					+ errorNumber.value+":"+errorMsg.value);
		}
			
			System.exit(0);
			// END SNIPPET: client
		} catch (Exception e) {
			e.printStackTrace();
			System.out.println("error: " + e.getMessage());
		}

	}
}

【总结】
1.当用到参数传递值时千万不要用acegi，不知道bug否，xfire的时候就发现有这个问题现在也未解决。
2.后续要认真研究aegis，没准能找到问题。
