eclipse本地使用jdbc調用oracle存儲過程

其實單就這個問題網上有很多博客,但是有個問題就是我們傳入的如果是array數組的數據的時候,最終oracle會接收不到數據,但是基本上所有博客都未曾提及,在這裏說明一下,需要maven引用一下orai18n這個包,詳細maven如下:

<!-- https://mvnrepository.com/artifact/cn.easyproject/orai18n -->
<dependency>
    <groupId>cn.easyproject</groupId>
    <artifactId>orai18n</artifactId>
    <version>12.1.0.2.0</version>
</dependency>

其次,調用存儲過程如果需要傳入數組參數的時候,需要創建type:

CREATE OR REPLACE TYPE ARRAY AS TABLE OF VARCHAR2

ARRAY 是數組的聲明

VARCHAR2是數組具體內容的聲明

下面貼上測試代碼,引用了網上的工具類,一起貼上:

package com.com.com.com;

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

public class JDBCUtils {

	private static String driver ="";
	private static String url = "";
	private static String user = "";
	private static String password = "";
	
	//1.註冊數據庫驅動。通過靜態代碼塊來編寫
	static{
	    try {
	        //反射
	        Class.forName(driver);
	    } catch (ClassNotFoundException e) {
	        throw new ExceptionInInitializerError(e);
	    }
	}

	//2.獲取數據庫連接
	public static Connection getConnection(){
	    try {
	        return DriverManager.getConnection(url,user,password);
	    } catch (SQLException e) {
	        e.printStackTrace();
	    }
	    return  null;
	}

	//3.獲取數據庫連接對象
	public static Statement getStatement() {
	    Statement st = null;
	    try {
	      st = getConnection().createStatement();
	    } catch (SQLException e) {
	      e.printStackTrace();
	    }
	    return st;
	}

	//6.關閉資源
	public static void release(Connection conn, Statement st, ResultSet rs){
	    //關閉數據庫連接資源
	    if(rs != null){
	        try {
	            rs.close();
	        } catch (SQLException e) {
	            e.printStackTrace();
	        }
	    }

	    //關閉數據庫連接對象資源
	    if(st != null){
	        try {
	            st.close();
	        } catch (SQLException e) {
	            e.printStackTrace();
	        }
	    }

	    //關閉查詢結果資源
	    if(conn != null){
	        try {
	            conn.close();
	        } catch (SQLException e) {
	            e.printStackTrace();
	        }
	    }
	}
}

package com.com.com.com;

import java.sql.CallableStatement;

import oracle.jdbc.OracleConnection;
import oracle.jdbc.OracleTypes;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;

public class TestProcedure {

	public static void main(String[] args) {
		OracleConnection  con = null;
		String execuSql = "{call H2.CPROC_GET_SALEINFO(?,?,?,?,?)}";
		CallableStatement call = null;
		String[] a = new String[]{"1"};
		String[] b = new String[]{"2"};
		try {
			con = (OracleConnection) JDBCUtils.getConnection();
			call = con.prepareCall(execuSql);
			ArrayDescriptor desc1 = ArrayDescriptor.createDescriptor("H2.VARCHAR2_ARRAY", con);
			ARRAY vArray = new ARRAY(desc1, con, a);
			ARRAY vArray2 = new ARRAY(desc1, con, b);
			call.setArray(1, vArray);
			call.setArray(2, vArray2);
			call.setString(3, "2");
			call.setString(4, "1");
			call.registerOutParameter(5, OracleTypes.VARCHAR);
			call.execute();
			System.out.println(call.getMoreResults());
			System.out.println(call.getString(5));
		} catch (Exception e) {
			e.printStackTrace();
		}finally {
			JDBCUtils.release(con,call,null);
		}
	}
}

我主要被oracle接收參數卡了大半天,寫出這個博客也是想大家能夠少走彎路!
