Hibernate的CRUD

对于Hibernate的增删改查，我们还是用一个案例来说明

下面是整个项目的目录结构：

 

一、com.mypro.domain包

封装person域模型

package com.mypro.domain;

public class Person {

    private int id;
    private String name;
    private int age;
    private String gender;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + ", age=" + age
                + ", gender=" + gender + "]";
    }
    public Person(int id, String name, int age, String gender) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
        this.gender = gender;
    }
    public Person() {
        super();
    }
    
}

 

定义QueryResult用来返回分页查询结果集以及表总所有记录数据的封装

package com.mypro.domain;

import java.util.List;

public class QueryResult {

    //返回数据库中某表总的记录数
    private long count;
    //返回结果集
    private List list;
    public long getCount() {
        return count;
    }
    public void setCount(long count) {
        this.count = count;
    }
    public List getList() {
        return list;
    }
    public void setList(List list) {
        this.list = list;
    }
    public QueryResult(long count, List list) {
        super();
        this.count = count;
        this.list = list;
    }
    public QueryResult() {
        super();
    }
    
}
