Eclipse neon +Hibernate5+maven创建小例子

来源：互联网发布：robotmaster软件下载编辑：程序博客网时间：2024/05/22 01:46

Eclipse+Maven搭建一个Hibernate5的小例子

一、新建一个maven项目

二、将第一个勾选上

三、创建好的项目结构

四、因为Eclipse neon新建maven项目默认的是支持servelt2.5，所以为了支持3.0的API进行如下设置，然后点击下面的链接

五、修改webapp目录

六、修改文件的maven class目录，并删除test的class

七、完成前面的步骤，项目目录结构（此处省略各个文件的创建）

源代码：

Students.java

package com.vae.entity;

import java.util.Date;

public class Students {

private int sid;
private String sname;
private String gender;
private Date birthday;
private String address;

public Students(){

}

public Students(int sid, String sname, String gender, Date birthday, String address) {
//super();
this.sid = sid;
this.sname = sname;
this.gender = gender;
this.birthday = birthday;
this.address = address;
}

public int getSid() {
return sid;
}

public void setSid(int sid) {
this.sid = sid;
}

public String getSname() {
return sname;
}

public void setSname(String sname) {
this.sname = sname;
}

public String getGender() {
return gender;
}

public void setGender(String gender) {
this.gender = gender;
}

public Date getBirthday() {
return birthday;
}

public void setBirthday(Date birthday) {
this.birthday = birthday;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}

@Override
public String toString() {
return "Students [sid=" + sid + ", sname=" + sname + ", gender=" + gender + ", birthday=" + birthday
+ ", address=" + address + "]";
}

}
