SSH spring+springmvc+hibernate+maven 整合详解

1、SSH框架介绍

1.1、Spring

Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。

1.2、SpringMVC

Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。

1.3、Hibernate

作为SSH三大框架之一的Hibernate，是用来把程序的Dao层和数据库打交道用的，它封装了JDBC的步骤，是我们对数据库的操作更加简单，更加快捷。利用Hibernate框架我们就可以不再编写重复的JDBC代码，不再反复的测试我们的SQL语句写的如何

2、项目环境

本项目的开发基于maven3.4.0，jetty6.1.26，mysql，eclipse，JDK7等

3、SSH整合步骤（超详细）  
首先新建一个maven项目，选择maven-archetype-webapp,一直下一步就好了  
本项目功能：模拟新增人员、编辑人员信息、删除人员信息  
项目目录如下：

3.1 配置pom.xml

        <tx:annotation-driven transaction-manager="transactionManager" />
    
    </beans>

3.4 配置springmvc.xml

4.业务代码编写

model层：Person.java

package com.iflytek.ssh.entity;
    
    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.Table;
    
    import org.hibernate.annotations.GenericGenerator;
    
    @Entity
    @Table(name="person")
    public class Person { 
    
        @Id
        @GenericGenerator(name="generator",strategy="uuid")
        @GeneratedValue(generator="generator")
        @Column(name = "id",nullable=false,length=32)
        private String id;
    
        @Column(name="name",length=100)
        private String name;
    
        @Column(name = "idCard",length=20)
        private String idCard;
    
        @Column(name="phone",length=20)
        private String phone;
    
        @Column(name="address",length=100)
        private String address;
    
    
        public String getId() {
            return id;
        }
        public void setId(String id) {
            this.id = id;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getIdCard() {
            return idCard;
        }
        public void setIdCard(String idCard) {
            this.idCard = idCard;
        }
        public String getPhone() {
            return phone;
        }
        public void setPhone(String phone) {
            this.phone = phone;
        }
        public String getAddress() {
            return address;
        }
        public void setAddress(String address) {
            this.address = address;
        }
    
    
    }

Dao层：编写CRUD操作PersonDao.java

package com.iflytek.ssh.dao;
    
    import java.util.List;
    
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Repository;
    
    import com.iflytek.ssh.entity.Person;
    
    /** * 数据层 * @author yanzhang9 * */
    @Repository
    public class PersonDao { 
    
        @Autowired
        private SessionFactory sessionFactory;
    
        private Session getSession(){
            return sessionFactory.getCurrentSession();
        }
    
        /** * 保存 */
        public void savePerson(Person person){
            this.getSession().save(person);
        }
    
        /** * 查看人员信息 * @return */
        @SuppressWarnings("unchecked")
        public List<Person> getPersons(){
            return this.getSession().createQuery("from Person ").list();
    // return this.getSession().createCriteria(Person.class).list();
        }
    
        /** * 删除 * @param id */
        public void deletePersonById(String id){
    // this.getSession().delete("id", id);
