采用jdbc批处理 提高jdbc效率 .

1.将jdbc操作改成批处理  addBatch(); //添加批处理

 

2.使用PreparedStatement

 

 

代码：

eg:

 

 

Connection conn = DBUtils.getInstance().getConnetion();

conn.setAutoCommit(false );

PreparedStatement pstmt = null;

try

pstmt = conn.preparedStatement("insert into test1(a,b) vlaues (?,?)");

pstmt.clearBatch();

for(int i = 0; i<100000;i++){

     pstmt.setInt(1,i);

     pstmt.setString(2,"value"+i);

     pstmt.addBatch();

    if(i % 10000){

            pstmt.executbeBatch();

    }



}





pstmt.executeBatch();



conn.commit();

} catch(Exception e) {

      conn.rollback();

}  finally {

     conn.setAutocommit(true);

}
