package com.transferdata; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.Date; import java.util.List; import com.mysql.jdbc.Connection; import com.mysql.jdbc.PreparedStatement; import com.entity.Customer; public class InsertNewSchame { private Connection newConn; public InsertNewSchame(Connection newConn){ this.newConn = newConn; } /* * 用throws Exception,而不用try/catch,目的是将异常全部抛到外层 */ public boolean insertCustomer(Customer customer, String id) throws Exception{ // account_id\mobile_app_info\zhima_score\device_token String sqlInsert = "INSERT INTO adm_sys_customer(email,idcard_no,login_name,mobile_no,password,real_name) " + "VALUES (?,?,?,?,?,?)"; PreparedStatement pstmt; pstmt = (PreparedStatement) newConn.prepareStatement(sqlInsert); pstmt.setString(1, customer.getEmail()); pstmt.setString(2, customer.getIdcardNo()); pstmt.setString(3, customer.getLoginName()); pstmt.setString(4, customer.getMobileNo()); pstmt.setString(5, customer.getPassword()); pstmt.setString(6, customer.getRealName()); pstmt.executeUpdate(); pstmt.close(); return true; } }
5、测试
外层捕获异常后执行回滚操作
package com.zkbc.transferdata; import java.sql.SQLException; import java.util.List; import com.mysql.jdbc.Connection; import com..entity.Customer; public class Testtest { /* * 外层捕获异常后执行回滚操作 */ public static void main(String args[]) { ConnectionUtils ConnectionUtils = new ConnectionUtils(); Connection oldConn = ConnectionUtils.getOldConn(); Connection newConn = ConnectionUtils.getNewConn(); GetOldData oldData = new GetOldData(oldConn); InsertNewSchame newData = new InsertNewSchame(newConn); try{ oldConn.setAutoCommit(false); newConn.setAutoCommit(false); String cuId = "0"; List<Customer> customerList = oldData.getCustomerList(); for(Customer customer:customerList) { cuId = (Integer.parseInt(cuId) + 1) + ""; //customer表和credit表 newData.insertCustomer(customer, cuId); } oldConn.commit(); newConn.commit(); }catch(Exception e) { e.printStackTrace(); try { oldConn.rollback(); newConn.rollback(); } catch (SQLException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } }finally { try { oldConn.setAutoCommit(true); newConn.setAutoCommit(true); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } ConnectionUtils.closeConnection(oldConn); ConnectionUtils.closeConnection(newConn); } } }
