使用方法如下：

Document doc = WebServiceInvoker.invoke(pushConfig.getPushUrl(),
							pushConfig.getWsNameSpace(),
							pushConfig.getWsHeaderNameSpace(),
							pushConfig.getWsHeaderPrefix(),
							pushConfig.getUserName(),
							pushConfig.getUserPassword(),
							new String[]{pushConfig.getParam()},
							new String[]{jsonString},
							pushConfig.getParamPrefix(),
							pushConfig.getWsMethodName(),
							pushConfig.getWsMethodPrefix()
						);

自定义的一个配置实体类：

package com.chinagas.org.beans;
 
import java.util.Date;
 
import org.springframework.format.annotation.DateTimeFormat;
 
//
public class PushConfig{
	//ID（通过序列：SEQ_PUSH_ID生成）
	private Long pushId;
	//推送名称
	private String pushName;
	//系统名称
	private String systemName;
	//推送地址
	private String pushUrl;
	//推送类型（ws，resful）
	private String pushType;
	//ws命名空间
	private String wsNameSpace;
	//ws调用方法名
	private String wsMethodName;
	//用户名

	//
	private Date createTime;
	//

	//
