java中调用oracle存储过程_java中调用oracle存储过程

2024-11-07 来源:个人技术集锦

1.   由于每个存储过程的参数不同,可以编写以一个类提出所有操作。

package com.lvhe.core.db;

import java.sql.CallableStatement;

import java.sql.Date;

import java.sql.SQLException;

import java.sql.Time;

import java.sql.Timestamp;

import java.util.ArrayList;

import java.util.List;

import com.lvhe.core.util.DateUtil;

public class PrecedureParam {

private List params = new ArrayList();

private List inout = new ArrayList();

public void push(Object obj, int index, boolean isIn) {

params.add(index, obj);

inout.add(index, isIn);

}

public int size() {

return params.size();

}

public String getContent() {

String cnt = "";

for(int i=0; i

if(i>0) {

cnt = cnt + ",";

}

cnt = cnt + "?";

}

return cnt;

}

public boolean isIn(int index) {

return inout.get(index);

}

public Object getParam(int index) {

return params.get(index);

}

public void setParams(CallableStatement call) throws SQLException {

for(int i=0; i

setParam(call, this.getParam(i), i+1, this.isIn(i));

}

}

public void execute(CallableStatement call) throws SQLException {

setParams(call);

call.execute();

getResult(call);

}

public void getResult(CallableStatement call) throws SQLException {

for(int i=0; i

if(!this.isIn(i)) {

Object obj = this.getParam(i);

if(obj instanceof String) {

params.set(i, call.getString(i+1));

}else if(obj instanceof Integer) {

params.set(i, call.getInt(i+1));

}else if(obj instanceof Date) {

params.set(i,  call.getDate(i+1));

}else {

params.set(i, call.getString(i+1));

}

}

}

}

public void setParam(CallableStatement call, Object obj, int index, boolean isIn) throws SQLException {

if(isIn) {

if(obj instanceof String) {

call.setString(index, (String)obj);

}else if(obj instanceof Integer) {

Integer v = (Integer)obj;

call.setInt(index, v.intValue());

}else if(obj instanceof Timestamp) {

call.setTimestamp(index, (Timestamp)obj);

}else if(obj instanceof java.util.Date) {

java.sql.Date sqlDate = DateUtil.toSQL((java.util.Date)obj);

call.setDate(index, sqlDate);

}else if(obj instanceof Date) {

call.setDate(index, (Date) obj);

}else if(obj instanceof Long) {

call.setLong(index,  (Long)obj);

}else {

call.setString(index, (String)obj);

}

}else {

if(obj instanceof String) {

call.registerOutParameter(index, java.sql.Types.VARCHAR);

}else if(obj instanceof Integer) {

call.registerOutParameter(index, java.sql.Types.INTEGER);

}else if(obj instanceof Timestamp) {

call.registerOutParameter(index, java.sql.Types.TIMESTAMP);

}else if(obj instanceof Date) {

call.registerOutParameter(index, java.sql.Types.DATE);

}else if(obj instanceof Long) {

call.registerOutParameter(index, java.sql.Types.NUMERIC);

}else {

call.registerOutParameter(index, java.sql.Types.VARCHAR);

}

}

}

public List getParams() {

return params;

}

public void setParams(List params) {

this.params = params;

}

}

2.  调用存储过程:

public void callPrecedure(String methodName, PrecedureParam param) {

Session session = getSession();

CallableStatement call = null;

Connection conn = session.connection();

try {

String preStr = "{Call "+methodName+"("+param.getContent()+")}";

call = conn.prepareCall(preStr);

param.execute(call);

param.getResult(call);

/*int i = call.getInt(13);

System.out.println(i);*/

} catch (SQLException e) {

e.printStackTrace();

} finally {

try {

call.close();

} catch (SQLException e) {

e.printStackTrace();

}

}

}

3. 使用方法:其中true表示输入,false表示输出。0为整数,“”为字符串。如果直接调用存储过程序号是从1开始的,此处从0开始。

//call precedure

PrecedureParam preceParam = new PrecedureParam();

preceParam.push(GUID, 0, true);

preceParam.push(jsonObj.get("Optor"), 1, true);

preceParam.push(DateUtil.toTimestamp(jsonObj.getString("localTime")), 2, true);

preceParam.push( 0, 3, false);

preceParam.push( "", 4, false);

preceParam.push( "", 5, false);

preceParam.push( "", 6, false);

preceParam.push( "", 7, false);

preceParam.push( "", 8, false);

preceParam.push( "", 9, false);

preceParam.push( "", 10, false);

preceParam.push( "", 11, false);

preceParam.push( 0, 12, false);

gridService.callPrecedure("spfee_placeBackupFileMerge", preceParam);

int status = (int) preceParam.getParam(12);

直接调用示例:

public HashMap spfee_placeBackupLogin(String placeCode, String softNameCode,

String softVersion,  Timestamp placeSystemTime, String DBType,

String DBBackupPwd,String placeIp) {

Session session = getSession();

CallableStatement call = null;

Connection conn = session.connection(); HashMap value = null; try { call = conn.prepareCall("{Call spfee_placeBackupLogin(?,?,?,?,?,?,?,?,?,?)}"); call.setString(1, placeCode);  call.setString(2, softNameCode ); call.setString(3,  softVersion); call.setTimestamp(4, placeSystemTime);  call.setString(5, placeIp ); call.setString(6, DBType ); call.setString(7, DBBackupPwd ); call.registerOutParameter(8, java.sql.Types.NUMERIC); call.registerOutParameter(9, java.sql.Types.CHAR); call.registerOutParameter(10, java.sql.Types.VARCHAR); call.execute(); int result = call.getInt(8); String secretKey = call.getString(9) ; String gatewayUrl = call.getString(10); System.out.println(result); value = new HashMap<>(); value.put("result", result); value.put("secretKey", secretKey); value.put("gatewayUrl", gatewayUrl); } catch (SQLException e) { e.printStackTrace(); } finally { try { call.close(); } catch (SQLException e) { e.printStackTrace(); } } return value; }
