用程序把shape文件直接寫入oracle數據庫——java

利用oracle提供的一個工具類可以很方便地把shape文件寫入oracle數據庫

主要是 oracle.spatial.util.SampleShapefileToJGeomFeature 類

該類提供了main（）方法，直接傳遞數據庫相關信息即可：

下面是一個我寫的源碼示例：

  1 import java.io.File;
  2 import java.io.FileNotFoundException;
  3 import java.sql.Connection;
  4 import java.sql.Statement;
  5 
  6 import javax.swing.JFileChooser;
  7 import javax.swing.filechooser.FileFilter;
  8 
  9 import oracle.spatial.util.SampleShapefileToJGeomFeature;
 10 
 11 import demo.Connect;
 12 
 13 
 14 public class UploadShapeFileToOracleDB {
 15     public static void main(String[] args) throws Exception {
 16         updata(args);
 17     }
 18     
 19     /**
 20      * Prompt for File if not provided on the command line. Don't forget the
 21      * quotes around your path if there are spaces!

 24      *             打開shp文件對話框 獲取相關參數 用到了兩個重要的

 27     private static File promptShapeFile(String[] args)

 43                             || f.getPath().endsWith("SHP");
 44                 }
 45                 public String getDescription() {
 46                     return "Shapefiles";
 47                 }
 48             });
 49             /*
 50              * 打開對話框

141         stmt.close();
142         connection.close();
143     }
144 }

Connect類為 ：

package demo;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Connect {
    private static String url = "jdbc:oracle:thin:@127.0.0.1:1521:XE";
    private static String username = "system";
    private static String pw = "root";
    private static Connection conn = null;

    public static Connection getConnect() {
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            try {
                conn = DriverManager.getConnection(url, username, pw);
            } catch (SQLException e) {
                e.printStackTrace();
            }
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
        return conn;
    }

    public void testConnect() {
        Connection con = getConnect();
        if (con == null)
            System.out.print("連接失敗");
        else
            System.out.print("連接成功");
    }
}

 

利用geotools也可實現shape文件存入oralce數據庫，但直接利用oracle提供的類來實現shape文件存入oracle數據庫還是很方便的！
