Spring4＋hibernate＋SpringMvc整合

最新 05-10

## 1.創建maven項目，編寫pom文件，把整合框架的相關jar包全都引入

## 2.把一些必要的配置文件正過來

2.1整合需要的配置文件：

1.jdbc.properties

2.log4j.properties

3.Springmvc的配置文件

4.hibernate的配置文件

（不使用jpa的註解 hibernate的映射文件。）

5.web.xml配置文件

## 3.Spring和hibernate和SpringMvc開始進行整合

hibernate是dao層的框架

SpringMvc是web層框架

Spring是一個容器管理，用來管理和集成其他層的框架的。

###3.1.Spring整合web層

SpringMVC的配置文件讓dispatcherServlet去載入：

SpringMVC的配置文件：spring-mvc.xml

```xml

?xml version=1.0 encoding=UTF-8?

beansxmlns=http://www.springframework.org/schema/beans

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

/bean

/beans

```

web.xml配置

```xml

servlet

servlet-classorg.springframework.web.servlet.DispatcherServlet/servlet-class

init-param

!-- contextConfigLocation固定 --

param-namecontextConfigLocation/param-name

!-- 1./* 攔截所有請求 css img js jsp html action 2.*.action/*.do *.action 可以攔截以.action結尾的請求

3./ 攔截css js image action請求不攔截jsp(推薦) --

filter-class

org.springframework.web.filter.HiddenHttpMethodFilter

/filter-class

/filter

filter-mapping

filter-nameHiddenHttpMethodFilter/filter-name

url-pattern/*/url-pattern

/filter-mapping

```

Spring的配置文件讓org.springframework.web.context.ContextLoaderListener該監聽器去載入

```xml

listener

!-- 默認是去WEB-INF下找 applicationContext.xml配置文件--

listener-classorg.springframework.web.context.ContextLoaderListener/listener-class

/listener

context-param

param-namecontextConfigLocation/param-name

param-valueclasspath:applicationContext-*.xml/param-value

/context-param

```

###3.2.Spring整合dao層

（hibernate.cfg.xml配置文件不要了。裡面的東西要全部寫到Spring配置文件中去）

applicationContext-dao.xml

配置數據源，整合hibernate

```xml

?xml version=1.0 encoding=UTF-8?

beansxmlns=http://www.springframework.org/schema/beans

```

## 4.編寫 dao,service,Controller進行測試

## 4.1.Controller層

package com.qf.controller;

```java

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.qf.model.User;

import com.qf.service.UserService;

@Controller

@RequestMapping(/user)

public class UserController {

@Autowired

private UserService userService;

@RequestMapping(/save)

public String add(User user) {

//調用Service保存

boolean flag = userService.save(user);

if(flag){

return success;

}

return error;

}

```

## 4.2.Servicer層

package com.qf.service;

import com.qf.model.User;

public interface UserService {

boolean save(User user);

}

package com.qf.service.impl;

import javax.management.RuntimeErrorException;

```java

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import org.springframework.transaction.interceptor.TransactionAspectSupport;

import com.qf.dao.UserDao;

import com.qf.model.User;

import com.qf.service.UserService;

@Service

public class UserServiceImplimplements UserService{

@Autowired

private UserDao userDao;

@SuppressWarnings(finally)

@Override

public boolean save(User user) {

// TODO Auto-generated method stub

boolean flag=true;

try {

userDao.add(user);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

flag=false;

System.out.println(===============================exception);

//TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();//回滾事務

throw new RuntimeException();

}

return flag;

}

```

## 4.3.Dao層

package com.qf.dao;

import com.qf.model.User;

public interface UserDao {

voidadd(User user);

}

package com.qf.dao.impl;

```java

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

import com.qf.dao.UserDao;

import com.qf.model.User;

@Repository

public class UserDaoImplimplements UserDao{

@Autowired

private SessionFactory sessionFactory;

```

```java

@Override

public void add(User user) {

// TODO Auto-generated method stub

Session session = sessionFactory.getCurrentSession();

session.save(user);

}

```
