struts2+hibernate3.3+spring3.0 实现零配置

目前对于这三大框架整合开发有很多人有这不同的看法，我在这提供一个自己比较喜欢的设计方式：

下面以搭建一个用户管理实验做为说明：

第一步：创建数据库（只需要建立数据库名字就可以了）

第二步：在myeclipse中切换到myeclipse database explorer 然后建立数据库连接（datebase driver）如图：我这里取名为：usermanager   完成待用

 

第三步：切换回myeclipse java enterprise界面；建立自己的项目：如我这里叫usermanager

第四步：建立对应的包：分别有action  service  serviceimpl  dao  daoimpl pojo  vo   tools用mvc设计模式    分三层一般建立这几个包就够了。

第五步：建立实体类并写好注解：如我这里就建立了：

package com.cn.nnny.ssh.pojo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

//用户实体
@Entity
@Table(name="users")
public class Users {
 private int  id;// 编号
 private String  name;//姓名
 private int age;//年龄
 private String  sex;//性别    男  女
 private Department department;//部门
 private String  telphone;//电话
 
 
 public Users(){
  
 }

@Id
@GeneratedValue
 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 getSex() {
  return sex;
 }

 public void setSex(String sex) {
  this.sex = sex;
 }

@ManyToOne
 public Department getDepartment() {
  return department;
 }

 public void setDepartment(Department department) {
  this.department = department;
 }

 public String getTelphone() {
  return telphone;
 }

 public void setTelphone(String telphone) {
  this.telphone = telphone;
 }
 
 
  
}

*********************************************************8

package com.cn.nnny.ssh.pojo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

//部门实体
@Entity
public class Department {
    private int depid;//编号
    private String depname;//名称
    private String address;//地址
   
    public Department(){
     
    }
@Id
@GeneratedValue
 public int getDepid() {
  return depid;
 }

 public void setDepid(int depid) {
  this.depid = depid;
 }

 public String getDepname() {
  return depname;
 }

 public void setDepname(String depname) {
  this.depname = depname;
 }

 public String getAddress() {
  return address;
 }

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

}
************************************************

第六步：加入三大框架的jar包:注意使用myeclipse给你添加包：特别是添加hibernate的支持的时候要选中之前创建的usermanager驱动（就是前面创建备用的那个）

有这几个基本够用：

 

第七步：完成spring配置文件的编写（其中不括事物等的控制）如：

****************************************************

第八步：部署项目到应用服务器上（我用tomcat）然后启动这样它就会给你自己创建数据库表以及他们之间的关系了.

****************************************************

 

第九步：方向工程（注意我们这里需要把生成的dao放到pojo这个包下  选择dao是选spring那个   至于为什么试试就知道了）对于不会反向工程的自己查查很简单的附个图：

 

 

对了：有的时候myeclipse不给你选择

那么你需要修改spring配置文件中

class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      
改成：

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

改后下面会报错 删除就可以了  等反向工程做完在改回来就行了

 

然后完成反向工程：

 

最后一步：

回到myeclipse中提取接口：然后把相应的类移到相应的包中就ok

（不要说不会用myeclipse自动提取接口哦！！）

************************************************************

最后附上action、service 、dao层的注解：

哦忘了；在dao实现类中腰加这么一句：

 

 @Autowired
 public void setSessionFactoryOverride(SessionFactory sessionFactory) {
  super.setSessionFactory(sessionFactory);
 }

***********************action中**********************************
