Hello Hibernate 实例(一) 基础实例，hellohibernate,HelloHiberna

HelloHibernate 实例是个最简单的Hibernate入门实例,对代码没其它要求,遵循一个就行,让人能一看就懂.1.Mysql里有一个Customer表,字段为id,name,age,job.2.Customer实例化类

Customer.java

package com.hibernate;public class Customer { private int id; private String name; private String age; private String job; public String getAge() {        return age;    } public void setAge(String age) {        this.age = age;    } 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 String getJob() {        return job;    } public void setJob(String job) {        this.job = job;    } }
