本文主要介绍利用maven搭建spring4+hibernate4开发环境。

首先我们创建一个maven项目，具体步骤就不详细介绍了，看看我们pom.xml文件

  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

pom文件中主要配置一些需要依赖的包，maven会帮我们管理这些包

解下来看看web.xml

具体我就不做过多的解释了，解下来是hibernate-config.xml的

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

  28.     </bean>
  29.  
  30.     <!-- Hibernate session factory -->
  31.     <bean id="sessionFactory"
  32.         class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

  34.             <ref bean="dataSource" />
  35.         </property>

  65.     <aop:config expose-proxy="true">
  66.         <!-- 只对业务逻辑层实施事务 -->

  69.         <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" />
  70.     </aop:config>
  71. </beans>

注意我们使用了申明式事务，hibernate4必须配置事务才能使用。

接下来看看spring的配置文件

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
  4.     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
  5.     xmlns:mvc="http://www.springframework.org/schema/mvc"
  6.     xsi:schemaLocation="
  7.         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
  8.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
  9.         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd

  11.         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
  12.  
  13.     <import resource="classpath*:hibernate-config.xml" />
  14.     <!-- 注解扫描包 -->
  15.     <context:component-scan base-package="com.lifesense" />
  16.  
  17.     <context:annotation-config />
  18.  
  19.     <!-- 开启AOP注解扫描 -->
  20.     <aop:aspectj-autoproxy proxy-target-class="true" />
  21.  
  22.     <!-- 启动JSON格式的配置 -->
  23.     <bean
  24.         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
  25.         <property name="messageConverters">
  26.             <list>
  27.                 <bean
  28.                     class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
  29.             </list>
  30.         </property>
  31.     </bean>
  32.  
  33.     <!-- 定义视图解析器 -->
  34.     <bean id="viewResolver"
  35.         class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  36.         <property name="prefix" value="/WEB-INF/view/"></property>
  37.         <property name="suffix" value=".jsp"></property>
  38.     </bean>
  39.  
  40.     <!-- 支持文件上传 -->
  41.     <bean id="multipartResolver"
  42.         class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  43.         <property name="defaultEncoding" value="utf-8" />
  44.         <property name="maxUploadSize" value="1048576000" />
  45.         <property name="maxInMemorySize" value="40960" />
  46.     </bean>
  47.  
  48. </beans>

环境配置基本完毕我们测试一下，写了一个user类

  1. package com.lifesense.entity;
  2.  
  3. import javax.persistence.Entity;
  4. import javax.persistence.GeneratedValue;
  5. import javax.persistence.Id;
  6. import javax.persistence.Table;
  7. /**
  8.  * 用户实体类
  9.  * @author Administrator
  10.  *
  11.  */
  12. @Entity
  13. @Table
  14. public class User {
  15.     //主键id
  16.     @Id
  17.     @GeneratedValue
  18.     private Integer id;
  19.  
  20.     private String name;
  21.  
  22.     private Integer age;
  23.  
  24.     public Integer getId() {
  25.         return id;
  26.     }
  27.  
  28.     public void setId(Integer id) {
  29.         this.id = id;
  30.     }
  31.  
  32.     public String getName() {
  33.         return name;
  34.     }
  35.  
  36.     public void setName(String name) {
  37.         this.name = name;
  38.     }
  39.  
  40.     public Integer getAge() {
  41.         return age;
  42.     }
  43.  
  44.     public void setAge(Integer age) {
  45.         this.age = age;
  46.     }
  47.  
  48. }

接下来是一个dao

  1. package com.lifesense.dao.impl;
  2.  
  3. import org.springframework.stereotype.Repository;
  4.  
  5. import com.lifesense.dao.UserDao;
  6. import com.lifesense.entity.User;
  7.  
  8. @Repository
  9. public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao{
  10.  
  11. }

service

  1. package com.lifesense.service.impl;
  2.  
  3. import javax.annotation.Resource;
  4.  
  5. import org.springframework.stereotype.Service;
  6.  
  7. import com.lifesense.dao.UserDao;
  8. import com.lifesense.entity.User;
  9. import com.lifesense.service.UserService;
  10.  
  11. @Service
  12. public class UserServiceImpl implements UserService{
  13.  
  14.     @Resource
  15.     private UserDao userDao;
  16.  
  17.     /**
  18.      * 获取用户
  19.      * @param id 用户id
  20.      * @return
  21.      */
  22.     public User getUser(Integer id){
  23.         return userDao.get(User.class, id);
  24.     }
  25.  
  26.     /**
  27.      * 增加一个用户
  28.      * @param user 用户实体
  29.      */
  30.     public void saveUser(User user){
  31.         userDao.save(user);
  32.     }
  33.  
  34. }

controller

  1. package com.lifesense.controller;
  2.  
  3. import javax.annotation.Resource;
  4.  
  5. import org.springframework.stereotype.Controller;
  6. import org.springframework.web.bind.annotation.RequestBody;
  7. import org.springframework.web.bind.annotation.RequestMapping;
  8. import org.springframework.web.bind.annotation.RequestMethod;
