Hibernate Spring Struts Bean XML

开发本项目的具体步骤请看：Struts2,Spring,Hibernate整合步骤

项目目录：

User.java

package com.zx.test.model;

public class User {

private Long id;

private String name;

private Integer age;

private String password;

// get/set方法

}

User.hbm.xml

<?xml version="1.0" encoding="utf-8"?>

UserDao.java

* 保存user
* @param user
*/
public void saveUser(User user){
// spring自带方法保存
this.getHibernateTemplate().save(user);
}

//update, delete ,findAll 方法同上，省略！

}

UserService.java

package com.zx.test.service;

import com.zx.test.dao.UserDao;
import com.zx.test.model.User;

public class UserService {

private UserDao userDao;

public void setUserDao(UserDao userDao) {

}

public void saveUser(User user){
userDao.saveUser(user);
}

// 在此处添加业务逻辑方法；
}

UserAction.java

package com.zx.test.action;

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}

private UserService userService ;

public void setUserService(UserService userService) {
  this.userService = userService;
}

public String userAdd(){

  this.userService.saveUser(user);

  return SUCCESS;
}

//添加action方法

}

index.jsp:

<form action="<%=request.getContextPath() %>/user/userAdd.action" name="form1" method="post">

       userName: <input type ="text" name="user.name"><br>
       password:<input type="password" name="user.password"><br>

       <input type="submit" value="submit"> <input type="reset" value="reset">
    </form>

userShow.jsp

在第一行添加 struts2 的标签

即：<%@ taglib prefix="s" uri="/struts-tags" %>

<body>

       userName: <s:property value="user.name"/><br>
       password:<s:property value="user.password"/><br>
       age:<s:property value="user.age"/>

</body>

struts.properties 文件可要可无！（可以自己配置）

开发本项目的具体步骤请看：Struts2,Spring,Hibernate整合步骤

配置文件请注意所用 DTD的版本，请去自己参照Struts2,Spring,Hibernate整合步骤完整配置文件
