1，编程式事务管理（jdbc的事务是绑定在connection上的）
Connection conn = null
try
{
Class.forName("com.mysql.jdbc.Driver")
conn = DriverManager.getConnection("jdbc:oracle:thin:@host:1521:SID","username","password")
conn.setAutoCommit(false) //取消自动提交
PreparedStatement ps = conn.prepareCall("update something")
ResultSet rs = ps.executeQuery()
conn.commit() //手动提交
}
catch (Exception e)
{
conn.rollback()
e.printStackTrace()
}
finally
{
conn.close()
}
2，声明式事务
先在工程的application.xml配置文件中添加如下代码，开启事务
<!-- 声明式事务控制配置 -->
<tx:annotation-driven transaction-manager="txManager"/>
<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="datasource" ref="bassDataSource"></property>
</bean>
然后在你需要开启事务的接口前面添加注解
@Transactional(rollbackFor = IOException.class)
public void add(String name) throws IOException
{
System.out.println("可以再类里和方法里面添加事务注解0~0")
throw new IOException()
}
直接调用接口方法就好
分布式事务处理（mysql貌似在5.X之后才支持） 的话，
1.可以直接使用spring+atomikos框架进行管理
参考：
就不贴测试代码了，自己看着配置吧
2，使用JTA（Java Transaction API）进行分布式事务管理（测试代码如下）
import java.sql.Connection
import java.sql.PreparedStatement
import java.sql.SQLException
import javax.naming.InitialContext
import javax.sql.DataSource
import javax.transaction.SystemException
import javax.transaction.UserTransaction
import com.mysql.jdbc.jdbc2.optional.MysqlDataSource
//分布式事务处理
public class transferAccount
{
@SuppressWarnings("null")
public void testTransferAccount()
{
UserTransaction userts = null
Connection connA = null
PreparedStatement psA = null
InitialContext context = null
Connection connB = null
PreparedStatement psB = null
try
{
//获得事务管理对象
userts = (UserTransaction) context.lookup("java:comp/UserTransaction")
//获取两个数据库
connA = getDataSourceA().getConnection()
connB = getDataSourceB().getConnection()
//开启事务
userts.begin()
//sql语句
psA = connA.prepareStatement("我加1")
psB = connB.prepareStatement("我减1")
//执行sql
psA.executeUpdate()
psB.executeUpdate()
//事务提交
userts.commit()
} catch (Exception e)
{
try
{
userts.rollback()
} catch (IllegalStateException | SecurityException
| SystemException e1)
{
e1.printStackTrace()
}
e.printStackTrace()
}
finally
{
try
{
psA.close()
psB.close()
connA.close()
connB.close()
} catch (SQLException e)
{
e.printStackTrace()
}
}
}
public DataSource getDataSourceA()
{
MysqlDataSource dataSource = new MysqlDataSource()
dataSource.setDatabaseName("mysql")
dataSource.setServerName("server")
dataSource.setPortNumber(1433)
dataSource.setUser("test")
dataSource.setPassword("test")
return dataSource
}
public DataSource getDataSourceB()
{
MysqlDataSource dataSource = new MysqlDataSource()
dataSource.setDatabaseName("mysql")
dataSource.setServerName("server")
dataSource.setPortNumber(1435)
dataSource.setUser("test1")
dataSource.setPassword("test1")
return dataSource
}
}
Statement换成preparedStatement，就有相应的set方法了。
或者既然addBatch里面传入的是String类型，那我们自己构造，
stmt.addBatch(“insert into users values ("+"values1"+","+"values2"+")")
或者既然是users类，我们可以根据users中属性是否为初始值来自动生成inset语句，下面是我以前写的代码，仅供参考
注释：
1、下面的User.NAME等就是user中name属性在表中的列名
2、方法ConvertStr就是把插入的列的value加上单引号。
private static String ConvertStr(Object object) {
return "'" + object.toString() + "'"
}
3、其他
public static final String strIns = "insert into users("
public static final String strVal = ") values("
public static final String strEnd = ")"
4、调用
stmt.addBatch(User.InsetStr(user))//这样就不用考虑传参了
代码如下：
public static String InsetStr(User user) {String StrCol = ""
String Values = ""
if (user.getName() != null &&!user.getName().equals("")) {
if (!StrCol.equals("")) {
StrCol = StrCol + "," + User.NAME

StrCol = StrCol + User.NAME
Values = Values + ConvertStr(user.getName())
