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:
[java]
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);
