使用JDBC插入多數據測試的3種實現方法

閒來無事，就想測試一下我的mysql插入數據的效率到底如何。
現在不清楚我的測試方法到位否，所以與大家分享一下，看看大家的意見。

測試的思路：
多次向表中插入1000條數據，看看每次使用了多少毫秒。現在我打算使用JDBC的方式去插入。

外話：
思路很簡單，不過我這裏使用了Spring JUnit,因爲我上癮了，非常地方便。想看看大家
是不是也這樣子使用。所以我在後文中附貼出我一些關於JUnit Spring的配置代碼，
想更多人來拋磚。
開始先看看錶結構，非常簡單的一個表，id是自動增長，ct裏就是我會隨加入內容的字段：

create table test (id int,ct chart);

 

 

Java代碼

import mumu.junit.Base.BaseTest; public class MangInsertTest extends BaseTest { private static Logger log = Logger.getLogger(MangInsertTest.class); private static final int INSERT_COUNT = 5000; private static final int TEST_COUNT = 10; @Autowired private UnitTestDAO unitDao; @Test public void test() throws Exception{ Connection conn = null; try{ conn = unitDao.getConnection(); conn.setAutoCommit(false);//將事務改成手工提交 String inSql = "insert into mang(ct)value(?)"; for(int i = 0; i < TEST_COUNT; ++i){ long s = System.currentTimeMillis(); long d = 0; PreparedStatement inPs = conn.prepareStatement(inSql); for(int k = 0; k < INSERT_COUNT; ++k){ inPs.setString(1, "prefix string " + System.currentTimeMillis()); inPs.addBatch();//放入批處理 } inPs.executeBatch(); conn.commit();//記得要提交喔 inPs.close(); d = System.currentTimeMillis() - s; log.info("used time:" + d); } conn.setAutoCommit(true);//將conn改成自動提交 }catch(Exception excep){ throw excep; }finally{ if(conn != null){ try { conn.close(); } catch (SQLException e) { // TODO Auto-generated catch block throw e; } } } } }

第一個我給出了所有代碼，這裏使用的jdbc批處理還有手工提交事務。
測試結果爲： 

Java代碼

INFO (MangInsertTest.java:42) - used time:822 INFO (MangInsertTest.java:42) - used time:522 INFO (MangInsertTest.java:42) - used time:540 INFO (MangInsertTest.java:42) - used time:531 INFO (MangInsertTest.java:42) - used time:500 INFO (MangInsertTest.java:42) - used time:541 INFO (MangInsertTest.java:42) - used time:500 INFO (MangInsertTest.java:42) - used time:521 INFO (MangInsertTest.java:42) - used time:490 INFO (MangInsertTest.java:42) - used time:721  

 

 

測試代碼2：

Java代碼

conn = unitDao.getConnection(); conn.setAutoCommit(false);//依然使用手動提交 String inSql = "insert into mang(ct)value(?)"; for(int i = 0; i < TEST_COUNT; ++i){ long s = System.currentTimeMillis(); long d = 0; PreparedStatement inPs = conn.prepareStatement(inSql); for(int k = 0; k < INSERT_COUNT; ++k){ inPs.setString(1, "prefix string " + System.currentTimeMillis()); inPs.executeUpdate(); } conn.commit(); inPs.close(); d = System.currentTimeMillis() - s; log.info("used time:" + d);

 

只給出與測試不同的地方，其他地方基本相同。
這裏只是將batch方式換成直接executeUpdate.
輸出結果 如下：

Java代碼

INFO (MangInsertTest2.java:41) - used time:692 INFO (MangInsertTest2.java:41) - used time:590 INFO (MangInsertTest2.java:41) - used time:531 INFO (MangInsertTest2.java:41) - used time:560 INFO (MangInsertTest2.java:41) - used time:681 INFO (MangInsertTest2.java:41) - used time:500 INFO (MangInsertTest2.java:41) - used time:511 INFO (MangInsertTest2.java:41) - used time:510 INFO (MangInsertTest2.java:41) - used time:683 INFO (MangInsertTest2.java:41) - used time:510

 

使用Spring框架作爲數據源：

Java代碼

package mumu.compass.unittest; import java.sql.Connection; import java.sql.SQLException; import org.springframework.jdbc.core.JdbcTemplate; public class UnitTestDAO { private JdbcTemplate jdbcTemplate; public Connection getConnection() throws SQLException{ return jdbcTemplate.getDataSource().getConnection(); } public JdbcTemplate getJdbcTemplate() { return jdbcTemplate; } public void setJdbcTemplate(JdbcTemplate jdbcTemplate) { this.jdbcTemplate = jdbcTemplate; } }

Java代碼

 package mumu.junit.Base; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.TestExecutionListeners; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.support.DependencyInjectionTestExecutionListener; import org.springframework.test.context.transaction.TransactionalTestExecutionListener; import org.springframework.transaction.annotation.Transactional; @RunWith(SpringJUnit4ClassRunner.class) @TestExecutionListeners({ DependencyInjectionTestExecutionListener.class}) @Transactional @ContextConfiguration(locations={"classpath*:/testContext.xml"}) public class BaseTest{ }

 

testContext.xml文件:
