springmvc+spring4.1.6+hibernate4.3.8整合注解-优快云博客

今天来整合了一下spring，hibernate。

其实在前面S2sh框架整合的学习下，整合这个感觉还是比较轻松的，首先导入的jar包一下少了很多，因为springmvc本来就是spring框架的一部分，只需要将spring-webmvc跟spring-web(这个包之前好像也要加入进去)这些jar包导入进来，其他部分就是spring的一些其他的jar包跟hibernate的一些jar包，这些包的导入在这里就不描述了，可以在csdn上下载整个测试项目进行查看：http://download.youkuaiyun.com/detail/mjcreator/9526168

另外，在这里还是要说一下，在这个项目中commons-pool跟commons-dbcp这两个包还是不可以少的。

好了，jar包的导入在这里不继续记录了。

接下来帖上原代码以供以后参看吧。

web.xml文件的配置：

applicationContext.xml文件：

jdbc.properties文件的配置：

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://localhost\:3306/item?useUnicode\=true&characterEncoding\=utf-8&autoReconnect\=true
jdbc.username=root
jdbc.password=123456

好了，到这里配置文件差不多了。

User类：

package cn.bdx.model;

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

@Entity
@Table(name="t_user")
public class User {

	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	private int id;
	private String name;
	private int 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;
	}
	
	
}

UserController类的代码：

package cn.bdx.controller;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import cn.bdx.model.User;
import cn.bdx.service.intf.UserService;


@Controller
@RequestMapping("/user")
public class UserController {

	@Resource
	private UserService userService;
	
	@RequestMapping("/add")
	public ModelAndView add(User user,ModelMap model) {
		this.userService.add(user);
		System.out.println("add user complete");
		return new ModelAndView("index",model);
	}

	@RequestMapping("/query")
	public ModelAndView query(ModelMap model) {
		this.userService.query();
		System.out.println("query user compelte");
		return new ModelAndView("index",model);
	}
	
	
	public UserService getUserService() {
		return userService;
	}

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

UserService接口的代码：

package cn.bdx.service.intf;

import java.util.List;

import cn.bdx.model.User;

public interface UserService {
	
	public void add(User user);
	
	public List<User> query();

}

UserServiceImpl类的代码：

package cn.bdx.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import cn.bdx.dao.intf.UserDao;
import cn.bdx.model.User;
import cn.bdx.service.intf.UserService;

@Service("userService")
public class UserServiceImpl implements UserService{
	@Resource
	private UserDao userDao;
	
	@Override
	public void add(User user) {
		this.userDao.add(user);
	}
	@Override
	public List<User> query() {
		return this.userDao.query();
	}
	public UserDao getUserDao() {
		return userDao;
	}
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	
	

}

UserDao接口的代码：

package cn.bdx.dao.intf;

import java.util.List;

import cn.bdx.model.User;

public interface UserDao {

	public void add(User user);
	
	public List<User> query();
}

UserDaoImpl类的代码：

package cn.bdx.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import cn.bdx.dao.intf.UserDao;
import cn.bdx.model.User;

@Repository("userDao")
public class UserDaoImpl implements UserDao{
	
	@Resource
	private HibernateTemplate hibernateTemplate;
	
	
	@Override
	@Transactional(readOnly=false)
	public void add(User user) {
		this.hibernateTemplate.save(user);
	}

	@Override
	public List<User> query() {
		List<User> userList = (List<User>)this.hibernateTemplate.find("from User");
		System.out.println(userList);
		return userList;
	}
	
	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}


	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}
	
	

}

好了到这里基本上的内容完毕了，接下来只需要部署并启动tomcat，访问http://localhost:8080/spring-hibernate-test/user/query或者http://localhost:8080/spring-hibernate-test/user/add进行测试即可。成功的话会跳转到index.jsp页面上去，并且在控制台有输出内容。

其实做这个项目我就是想看看一个事情，那就是我将springmvc-servlet.xml这个配置文件不要看看能不能行，事实证明是可以的，只是将需要修改几个地方。首先一个修改的地方就是web.xml文件中关于设置springmvc的servlet处：

如果需要springmvc-servlet.xml这个文件，配置的方式如下：注意"param-value"的值。

<servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:*-servlet.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>

如果不需要这个文件，则需要指定一个其他的xml配置文件来完成springmvc的视图解析器bean的配置，我这里指定的是applicationContext.xml文件，这个web.xml文件关于springmvc的配置如下：注意其中的"param-value"的值。其实看这两个"param-value"的值不难看出，只是将对应xml文件的名称换了而已。

<servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:applicationContext.xml</param-value>
  	</init-param>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>

然后就是springmvc视图解析器bean的注入代码：

 <!-- springmvc的配置 -->
		<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="/" />
			<property name="suffix" value=".jsp" />
		</bean>
