JAVA开发2--java开发调用webservice抽取数据

开发类调用webservice并插入数据库：

新建个PACKAGE：com.noahark.dao

包括两个类：DBUtil（连接数据库）和ImportData（调用webservice）。

 

开发过程如下：

1.新建PACKAGE：

finish。

2.新建并开发DBUtil类：

注：由于此处会用到ojdbc6.jar，提前导入ojdbc6.jar，

从网上下载jar包，导入path：

导入成功：

开发代码：

package com.noahark.dao;

 

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;

import java.sql.ResultSet;

import java.sql.Statement;

 

publicclass DBUtil

{

  publicstatic Connectionconn;

  publicstatic PreparedStatementps;

  publicstatic ResultSetrs;

  publicstatic Statementst;

  privatestatic Stringurl ="jdbc:oracle:thin:@ip:1521:sid";

 

  privatestatic Stringuser ="username";

 

  privatestatic Stringpassword ="password";

 

  public Connection getConnection()

  {

    try

    {

      Class.forName("oracle.jdbc.driver.OracleDriver");

      conn = DriverManager.getConnection(url,user,password);

    }

    catch (Exception e) {

      e.printStackTrace();

    }

    returnconn;

  }

}

3.新建并开发ImportData类：

新建类同上（略）。

需要导入dom4j-1.6.1.jar包。导入过程略。

开发代码如下：

package com.noahark.dao;

 

import gn.budget.service.*;

import org.dom4j.Document;

import org.dom4j.DocumentException;

import org.dom4j.DocumentHelper;

import org.dom4j.Element;

 

import java.sql.Connection;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import java.util.List;

 

public class ImportData {

         privatestatic Connection conn;

         privatestatic Statement st;

         privatestatic ResultSet rs;

          

         publicstatic void main(String[] args) throws IOException_Exception,DocumentException, SQLException{

                   //客户提供ServiceBudget

                   ServiceBudgetBudget = new ServiceBudgetService().getServiceBudgetPort();

                  

                   Stringyear = "2016";

                   Stringmonth = "08";

                 

                   //客户提供getBudgetMonthOccurrence方法

                   Stringresult = Budget.getBudgetMonthOccurrence(year, month);

                  

                   System.out.println("输出webservice结果之前...!");

                  

                   System.out.println(result);

                   Documentdocument =DocumentHelper.parseText(result);

 

                   Elementroot = document.getRootElement();

                   ListchildElements = root.elements();             

 

             DBUtil jdbc = new DBUtil();

             conn = jdbc.getConnection();           

                   for(Element child : childElements) {

                               String sql2 = "insert intoOA_TEST(ACCOUNT,ENTITY,YEARS,PERIOD,PRODUCT,CYCLE,SCENARIO,VERSION,PROJECT,CUSTOM1,CUSTOM2,CUSTOM3,DATA,CREATED)values("+"'"+child.elementText("ysdycode")+"'"+","+"'"+child.elementText("kmcode")+"'"+","+"'"+child.elementText("year")+"'"+","+"'"+child.elementText("month")+"'"+",'PRODUCT'"+",'CYCLE'"+",'SCENARIO'"+",'VERSION'"+",'PROJECT'"+",'CUSTOM1'"+",'CUSTOM2'"+",'CUSTOM3',"+child.elementText("je")+",sysdate"+")"+"";

                               //String sql2 = "insert into OA_TESTvalues ('a','a','a','a','a','a','a','a','a','a','a','a','a','a','a',0,sysdate)";

                               DBUtil jdbc2 = new DBUtil();

                               Connection conn2 = jdbc.getConnection();

                               Statement st2 = conn2.createStatement();

                               st2.executeQuery(sql2);

                               st2.close();

                               conn2.close();

                              }

                   System.out.println("Success!");

         }

}
