Java，for循环插入数据库时，如中间发生错误，如何撤销之前已产生的所有结果(使用的是springJdbctemplate

package com.redking.jdbc.demo;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class JDBCDemo07 {
public static final String DBDRIVER = "sun.jdbc.odbc.JdbcOdbcDriver" ;
public static final String DBURL = "jdbc:odbc:testDB" ;
public static void main(String[] args) {
Connection conn = null ;
Statement pstmt = null ;
try {
// 向JAVA容器中加载驱动
Class.forName(DBDRIVER) ;
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
conn = DriverManager.getConnection(DBURL) ;
} catch (SQLException e) {
e.printStackTrace();
}
try {
pstmt = conn.createStatement() ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael001',31)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael002',32)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael003',33)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael'http://redking.blog.51cto.com',34)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael005',35)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael006',36)") ;
pstmt.addBatch("INSERT INTO person(name,age) VALUES ('Michael007',37)") ;
} catch (SQLException e) {
e.printStackTrace();
}
//取消自动提交
try {
conn.setAutoCommit(false);
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
//现在执行数据库的更新操作
try {
pstmt.executeBatch() ;
//如果没有错误，则表示可以向下执行
//手工提交
conn.commit();
} catch (SQLException e) {
e.printStackTrace();
//如果出错了，则应该把数据回滚
try {
conn.rollback();
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
try {
pstmt.close() ;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
conn.close() ;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
就发现程序出错，全部没有插进去。
