Spring、SpringMVC、Hibernate详细整合实例，包含所有步骤

Eclipse完整工程如下　　　　　　　　　　　　　　　　　　　　　　　　　　Jar包如下


　　　　　　


其中，整个工程主要可以分为四个部分（个人见解，怎么容易理解怎么来）

第一部分：配置文件

1、applicationContentx.xml：配置Spring容器相关内容.

1.1 hibernate.cfg.xml：

1.2 jdbc.properties：

2、Springmvc.xml：配置Springmvc相关内容

3、web.xml：配置整个工程相关内容

第二部分：（映射数据库）

1、实体类Entities

2、*.hbm.xml

第三部分：MVC：

1、控制层Controller（C）

2、业务逻辑层Service、Dao（M）

3、视图层index.jsp（V）

第四部分：JAR包

1、Spring3.X

2、Hibernate3.X

3、连接SqlServer2008数据库：sqljdbc4.jar（其他数据库使用对应的jar包即可）

4、数据库连接池：c3p0

5、commons-logging的jar包

具体代码如下：

第一部分：配置文件

1、applicationContentx.xml

</beans>

1.1 hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

<!-- 映射数据库对应实体类：注解生效方式生效方式 -->
<!-- <mapping class="Entity.Student"/> -->

</session-factory>

</hibernate-configuration>

1.2 jdbc.properties（根据个人的数据库，更改对应的参数，我的数据库名字是test）

driverClass = com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbcUrl = jdbc:sqlserver://localhost:1433;database=test
user = sa
password = xxxxx

2、Springmvc.xml

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

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 注解扫描包，注意换成自己的路径 -->
<context:component-scan base-package="com.zit">

</beans>

3、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

</filter-class>
</filter>

<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

第二部分：（映射数据库）,我的数据库名字是test，里面有张Student表，有id（自增、主键），age，name三个字段

1、实体类Entities：Student.java

package com.zit.entities;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

public class Student {

private int id;

private String name;

private int age;

public Student(){}

public Student(int id,String name,int age){
this.id=id;
this.name=name;
this.age=age;
}

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;
}
}

2、Student.hbm.xml：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.zit.entities.Student" table="Student">
<meta attribute="class-description">
This class contains the employee detail.
</meta>
<id name="id" type="int" column="id">
<generator class="native"/>
</id>
<property name="name" column="name" type="string"/>
<property name="age" column="age" type="int"/>
</class>
</hibernate-mapping>

第三部分：MVC：

1、控制层Controller（C）：StudentController.java

package com.zit.controller;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.zit.entities.Student;
import com.zit.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {

@Autowired
private StudentService studentService;

@RequestMapping("/getAllStudent")
public String getAllStudent(HttpServletRequest request){
String ss = request.getParameter("userName");
List<Student> students  = studentService.getAllStudent();
for(Student s : students){
System.out.println(s.getId());
System.out.println(s.getName());
System.out.println(s.getAge());
}
return "index";//返回index.jsp页面

}

}

2、业务逻辑层Service、Dao（M）

2.1.1 StudentService.java

package com.zit.service;

import java.util.List;

import com.zit.entities.Student;

public interface StudentService {

public List<Student> getAllStudent();

}

2.1.2 StudentServiceImpl.java

package com.zit.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.zit.dao.StudentDao;
import com.zit.entities.Student;
import com.zit.service.StudentService;

@Service
public class StudentServiceImpl implements StudentService{

@Autowired
private StudentDao studentDao;

@Override
public List<Student> getAllStudent() {
return studentDao.getAllStudent();
}

}

2.2.1 StudentDao.java

package com.zit.dao;

import java.util.List;

import com.zit.entities.Student;

public interface StudentDao {

public List<Student> getAllStudent();

}

2.2.1 StudentDaoImpl.java

package com.zit.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.zit.dao.StudentDao;
import com.zit.entities.Student;

@Repository
public class StudentDaoImpl implements StudentDao{

@Resource(name = "sessionFactory")
private SessionFactory sessionFactory;

@Override
@Transactional
public List<Student> getAllStudent() {
String hql = "from Student";
//getCurrentSession()比openSession()安全，注意web.xml中的配置，不然会报错
Session session = sessionFactory.getCurrentSession();
Query query = session.createQuery(hql);

return query.list();
}

}

3、视图层index.jsp（V）：index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>

<script type="text/javascript">
function addUser(){
var form = document.forms[0];
form.action = "/SSH/student/getAllStudent";
form.method="post";
form.submit();
}
</script>

</head>
<body>
<h1>添加用户</h1>
<form action="" name="userForm">
姓名：<input type="text" name="userName">
年龄：<input type="text" name="age">
<input type="button" value="添加" onclick="addUser()">
</form>

</body>
</html>

以上配置文件是完整、可行的，建议不要擅自删除，

因为本人搭建期间遇到过几个报错，就是因为擅自删除配置文件，比如:

No Hibernate Session bound to thread, and configuration does not allow creat

等等，在此不一 一列举。

到此，搭建好一个能访问数据库的SSH工程，启动Tomcat，可运行查看效果。

这里的jsp页面只是用来打断点验证能否正常访问数据库的，没有实际意义……
