Maven 搭建SpringMVC+Hibernate项目详解

前言

     今天复习一下SpringMVC+Hibernate的搭建,本来想着将Spring-Security权限控制框架也映入其中的,但是发现内容太多了,Spring-Security的就留在下一篇吧,这篇主要搭建SpringMVC4.1.4和Hibernate4.3.8,之前也打了好多SpringMVC的,这部分已经非常的熟悉了,毕竟业开发过一年多SpringMVC的,这次持久层采用Hibernate,数据源采用c3p0,数据库暂采用MySQL,主要是想复习一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下:

     1、设计数据库:设计好表结构,最好符合3NF,采用Hibernate tools将设计好的表自动生成对应的实体entity。 

     1、创建Maven项目,按需映入Maven包依赖。

     2、搭建Spring:配置Spring对控件层Bean的注入。

     3、搭建Hibernate:配置数据源,配置SessionFactory,配置事务,以及二级缓存ehcache的配置。

     4、测试Spring+Hibernate的框架搭建,写单元测试JUnit,测试事务配置等。

     5、映入SpringMVC:配置SpringMVC配置信息。

     6、配置web.xml容器

     7、测试三个框架的整合:Maven编译打包部署服务器,测试。

1、数据库设计

       设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色,一个角色多个用户所拥有;一个角色拥有多个权限,一个权限对应多个角色。所以按照数据库表结构设计,符合3NF的话我们需要5张表进行存在。表的具体信息就不列出了(可以下在源码,里面还有数据库),表关系如下:

      这里面ID才用到是java的UUID(36位)

2、创建Maven项目,编写pom.xml文件

      创建一个Maven的webapp项目,编写pom.xml文件,引入所需的包依赖,我这里就将所需的全部的映入了。

3、引入Spring配置

    编写配置文件,配置文件放在src/main/resources资源目录下(下同)。

   项目所需的配置信息config.properties

 

#application configs

#jdbc c3p0 config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 12345

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下:



 
 
 
 
 



上面spring配置了对应包下组件bean自动注入管理,我们需要将dao,service的实现类交由spring管理,如(@Repository,@Service)。

3.2、引入日志文件配置Log4j

 log4j.properties的配置文件如下:

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n



4、Hibernate配置

      Hibernate的配置主要包括:配置数据源c3p0,配置SessionFactory,配置事务管理器,配置事务管理,其spring-hibernate.xml文件如下:

 




 
 
 
 
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 
 
 
 
 
 ${hibernate.dialect}
 ${hibernate.show_sql}
 ${hibernate.format_sql}
 ${hibernate.hbm2ddl.auto}

 
 ${hibernate.cache.use_second_level_cache}
 ${hibernate.cache.use_query_cache}
 ${hibernate.cache.region.factory_class}
 ${hibernate.cache.provider_configuration_file_resource_path}
 
 
 
 
 
 

 
 
 
 

 
 
 
 
 
 
 

 
 
 
 

 
 

 
 

 
 
 
 
 
 
 



 上面配置了二级缓存,ehcache,相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置,下面是二级缓存的配置。

4.1、ehcache.xml的配置      



 
 
 
 
 

 

  





   上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

5、生成业务entity实体

      设计好数据表后,Hibernate的实体有工具Hibernate tools自动生成,Eclipse需要安装Hibernate tools插件(我在线安装过几次都不成功,推荐使用links离线安装,附录将介绍),所以不需要手工的书写,下面就贴一个用户信息的实体,AcctUser.java

 

package org.andy.work.entity;

// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0

import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

/**
 * AcctUser generated by hbm2java
 */
@Entity
@Table(name = "acct_user", catalog = "work")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class AcctUser implements java.io.Serializable {

 /**
 * 
 */
 private static final long serialVersionUID = 6980093847795726310L;
 private String id;
 private String nickName;
 private String telephone;
 private Date registerTime;
 private Set acctRoles = new HashSet(0);

 public AcctUser() {

 }

 public AcctUser(String id, String nickName) {
 this.id = id;
 this.nickName = nickName;
 }

 public AcctUser(String id, String nickName, String telephone,
 Date registerTime, Set acctRoles) {
 this.id = id;
 this.nickName = nickName;
 this.telephone = telephone;
 this.registerTime = registerTime;
 this.acctRoles = acctRoles;
 }

 @Id
 @Column(name = "id", unique = true, nullable = false, length = 36)
 public String getId() {
 return this.id;
 }

 public void setId(String id) {
 this.id = id;
 }

 @Column(name = "nick_name", nullable = false)
 public String getNickName() {
 return this.nickName;
 }

 public void setNickName(String nickName) {
 this.nickName = nickName;
 }

 @Column(name = "telephone")
 public String getTelephone() {
 return this.telephone;
 }

 public void setTelephone(String telephone) {
 this.telephone = telephone;
 }

 @Temporal(TemporalType.TIMESTAMP)
 @Column(name = "register_time", length = 19)
 public Date getRegisterTime() {
 return this.registerTime;
 }

 public void setRegisterTime(Date registerTime) {
 this.registerTime = registerTime;
 }

 @JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})
 @ManyToMany(fetch = FetchType.LAZY)
 @Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
 @JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })
 public Set getAcctRoles() {
 return this.acctRoles;
 }

 public void setAcctRoles(Set acctRoles) {
 this.acctRoles = acctRoles;
 }

}

上面有几个需要注意的:

     上面大多数都是Hibernate tools自动生成的,但是有几个需要手动添加:

              1、如果这个实体使用二级缓存的话,需要添加@cache注解;

              2、如果该实体里面还有集合元素(set, map,list),如果实体要采用二级缓存,那么这些集合元素必须也添加@cache注解。

              3、@JsonIgnoreProperties注解是为了防止SpringMVC在json返回时产生循环输出使用,如果不配置的话就会出现json死循环(还有多对多,一对多的属性时)。

             4、@JsonIgnore这个是在转换成json是忽略该属性,而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})则是忽略acctRoles里面的acctUsers和acctAuthorites属性。

6、创建Dao层

6.1Dao接口

              Dao层和Service层我们肯定采用的是面相接口编程的思想,所以,我们先定义一个通用的Dao接口,GenericDao.java

 

package org.andy.work.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 创建时间:2015-2-6 下午2:26:42
 * 
 * @author andy
 * @version 2.2
 * 
 * Dao通用接口
 */

interface GenericDao {
 
 T load(PK id);
 
 T get(PK id);
 
 List findAll();
 
 void persist(T entity);
 
 PK save(T entity);
 
 void saveOrUpdate(T entity);
 
 void delete(PK id);
 
 void flush();
}

            在定义具体的UserDao.java接口        

package org.andy.work.dao;

import org.andy.work.entity.AcctUser;

/**
 * 创建时间:2015-2-6 下午2:43:50
 * 
 * @author andy
 * @version 2.2
 * 
 * 用户Dao接口
 */

public interface UserDao extends GenericDao {

}

6.2、Dao层实现类

    我们需要将Dao层的实现类注入为bean,所以需要添加@Repository注解,UserDaoImpl如下:

package org.andy.work.dao.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

/**
 * 创建时间:2015-2-6 下午2:45:14
 * 
 * @author andy
 * @version 2.2
 */
@Repository("userDao")
public class UserDaoImpl implements UserDao {

 @Autowired
 private SessionFactory sessionFactory;

 private Session getCurrentSession() {
 return this.sessionFactory.getCurrentSession();
 }

 @Override
 public AcctUser load(String id) {
 return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);
 }
 
 @Override
 public AcctUser get(String id) {
 return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);
 }

 @SuppressWarnings("unchecked")
 @Override
 public List findAll() {
 List acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();
 return acctUsers;
 }

 @Override
 public void persist(AcctUser entity) {
 this.getCurrentSession().persist(entity);

 }

 @Override
 public String save(AcctUser entity) {
 return (String) this.getCurrentSession().save(entity);
 }

 @Override
 public void saveOrUpdate(AcctUser entity) {
 this.getCurrentSession().saveOrUpdate(entity);
 }

 @Override
 public void delete(String id) {
 AcctUser entity = this.load(id);
 this.getCurrentSession().delete(entity);
 }

 @Override
 public void flush() {
 this.getCurrentSession().flush();

 }

}

7、创建Service层

  7.1、Service层接口

package org.andy.work.service;

import java.util.List;

import org.andy.work.entity.AcctUser;

/**
 * 创建时间:2015-2-6 下午3:18:57
 * 
 * @author andy
 * @version 2.2
 * userService接口
 */

public interface UserService {
 AcctUser load(String id);

 AcctUser get(String id);

 List findAll();

 void persist(AcctUser entity);

 String save(AcctUser entity);

 void saveOrUpdate(AcctUser entity);

 void delete(String id);

 void flush();
}

  7.2、service层实现类

   UserServiceImpl就需要注入上面定义的Dao层bean。

package org.andy.work.service.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 创建时间:2015-2-6 下午3:24:16
 * 
 * @author andy
 * @version 2.2 UserService 的实现
 */
@Service("userService")
public class UserServiceImpl implements UserService {

 @Autowired
 private UserDao userDao;

 @Override
 public AcctUser load(String id) {
 return userDao.load(id);
 }

 @Override
 public AcctUser get(String id) {
 return userDao.get(id);
 }

 @Override
 public List findAll() {
 return userDao.findAll();
 }

 @Override
 public void persist(AcctUser entity) {
 userDao.persist(entity);
 }

 @Override
 public String save(AcctUser entity) {
 return userDao.save(entity);
 }

 @Override
 public void saveOrUpdate(AcctUser entity) {
 userDao.saveOrUpdate(entity);
 }

 @Override
 public void delete(String id) {
 userDao.delete(id);
 }

 @Override
 public void flush() {
 userDao.flush();
 }

}

8、测试Spring和Hibernate的整合

    我们可以在src/test/java编写测试类,测试上面的配置,如果测试成功已经基本大功告成。

 

package org.andy.work.service;

import java.util.Date;
import java.util.List;
import java.util.UUID;

import org.andy.work.entity.AcctUser;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**
 * 创建时间:2015-2-6 下午3:31:07
 * 
 * @author andy
 * @version 2.2
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
 "classpath:spring-hibernate.xml" })
public class TestUserService {

 private static final Logger LOGGER = Logger
 .getLogger(TestUserService.class);

 @Autowired
 private UserService userService;

 @Test
 public void save() {
 AcctUser acctUser = new AcctUser();
 acctUser.setId(UUID.randomUUID().toString());
 acctUser.setNickName("andy");
 acctUser.setRegisterTime(new Date());
 acctUser.setTelephone("13022221111");
 String id = userService.save(acctUser);
 LOGGER.info(JSON.toJSONString(id));
 }

}

9、引入SpringMVC

     添加spring-mvc.xml文件

 




 
 

 
 
 
 
 
 
 
 text/html;charset=UTF-8
 application/json;charset=UTF-8
 
 

 
 
 

 
 
 
 
 
 



   上面配置了包扫描Controller,[email protected]��,和视图层的配置。

10、配置web.xml容器

      web容器是web项目的大脑,所以web容器,首先需要引入spring,让spring管理各个框架,并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

web.xml文件如下:

 




 springmvc_demo

 
 contextConfigLocation
 classpath:spring.xml,classpath:spring-hibernate.xml
 

 
 encodingFilter
 org.springframework.web.filter.CharacterEncodingFilter
 
 encoding
 utf-8
 
 
 forceEncoding
 true
 
 
 
 encodingFilter
 /*
 

 
 
 openSessionInViewFilter
 org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
 
 singleSession
 true
 
 

 
 
 org.springframework.web.context.ContextLoaderListener
 

 
 
 org.springframework.web.util.IntrospectorCleanupListener
 

 
 spring mvc servlet
 rest
 org.springframework.web.servlet.DispatcherServlet
 
 contextConfigLocation
 
 classpath:spring-mvc.xml
 
 1
 

 
 rest
 *.htmls
 

 
 openSessionInViewFilter
 *.htmls
 

 
 
 30
 

 
 /index.jsp
 


11、创建控制层Controller

     控制层UserController

package org.andy.work.controller;

import java.util.List;

import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/** 
 * 创建时间:2015-2-7 上午11:49:00 
 * @author andy 
 * @version 2.2 
 * 描述: 用户Controller
 */
@Controller
@RequestMapping("/user")
public class UserController {

 private static final Logger LOGGER = Logger.getLogger(UserController.class);
 
 @Autowired
 private UserService userService;
 
 @RequestMapping("/showInfo/{userId}")
 public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
 LOGGER.info("查询用户:" + userId);
 AcctUser userInfo = userService.load(userId);
 modelMap.addAttribute("userInfo", userInfo);
 return "/user/showInfo";
 }
 
 @RequestMapping("/showInfos")
 public @ResponseBody List showUserInfos(){
 LOGGER.info("查询用户全部用户");
 List userInfos = userService.findAll();
 return userInfos;
 }
}

12、创建视图层

   在src/main/webapp/WEB-INF/views下 创建user/showInfo.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%
 String path = request.getContextPath();
 String basePath = request.getScheme() + "://"
 + request.getServerName() + ":" + request.getServerPort()
 + path + "/";
%>






userInfo


 用户信息 昵称: ${userInfo.nickName} 用户id:${userInfo.id} 用户电话:${userInfo.telephone } 注册时间:
 
 角色:[
 
  ${role.name } 权限[
  
  ${authority.name } 
   ]
  
 ]

 
ajax显示全部用户信息:

13、部署服务器测试

          使用Maven打包部署:clean compile  package

          部署到tomcat,测试
          主要测试上面的  http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

                                  和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls  (json数据返回)
          上面视图层就包含了这两条url请求的测试:
