Spring Learning -9-spring and hibernate integration

Spring and Hibernate integration

Steps

1) Introduction of JAR Package

Connection pool/Database driver package

Hibernate-related JAR packages

Spring core packages and AOP packages

Spring-orm

Spring-tx

2) configuration

Hibernate.cfg.xml

Bean.xml

3) Build

Package com.cx.entity;/** * Created by Cxspace on 16-8-11. */public class Dept {    private int id;    private String name;    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;    }}
