三种批量增加的性能分析_MySQL

gaodaima.com

最近在深入学习hibernate,在进行批量操作时,发现hibernate批量操作性能非常低.于是就想找一个性能较高的方法,在对jdbc、jdbcTemplate、hibernate进行测试后,发现jdbc的执行效率是最高的,jdbcTemplate也很相近,hibernate就不考虑了,惨不忍睹啊.下面把代码写出来,希望大家批评指正.

首先domain对象.在这里使用的注解的方式,都是比较新的版本.

User.java

 1 package com.bao.sample.s3h4.domain; 2  3 import javax.persistence.Column; 4 import javax.persistence.Entity; 5 import javax.persistence.GeneratedValue; 6 import javax.persistence.GenerationType; 7 import javax.persistence.Id; 8 import javax.persistence.Table; 9 10 import com.bao.sample.base.domain.BaseDomain;11 12 @Entity13 @Table(name = "t_user")14 public class User extends BaseDomain {15 16     private static final long serialVersionUID = 1L;17     private int id;18     private String username;19     private String password;20 21     /**22      * @Description 注解最好标记在get方法上.注意:采用一致的标记方式,注解是以Id的标记方式为准的,如果标记在get方法上,则忽略property上的注解.23      * @return24      */25     @Id26     @GeneratedValue(strategy = GenerationType.IDENTITY)27     public int getId() {28         return id;29     }30 31     public void setId(int id) {32         this.id = id;33     }34 35     @Column(nullable = false)36     public String getUsername() {37         return username;38     }39 40     public void setUsername(String username) {41         this.username = username;42     }43 44     @Column(nullable <p>本文来源gao!daima.com搞$代!码#网#</p>= false)45     public String getPassword() {46         return password;47     }48 49     public void setPassword(String password) {50         this.password = password;51     }52 53     public User() {54         super();55     }56 57     public User(int id, String username, String password) {58         super();59         this.id = id;60         this.username = username;61         this.password = password;62     }63 64 }
