spring4+hibernate4+maven环境搭建

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

<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

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

<listener>

<param-name>contextConfigLocation</param-name>
<param-value>classpath:context-servlet.xml</param-value>
</context-param>

<!-- 配置前端分发器 -->

<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:context-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>

<!-- 设置编码格式 -->

</init-param>
</filter>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

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

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd"> 
<!-- 读取配置文件 -->
<context:property-placeholder location="classpath:jdbc.properties" />

<!-- 配置数据库连接池 dbcp -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="${jdbc.maxActive}" />

<property name="logAbandoned" value="${jdbc.logAbandoned}" />
<property name="validationQuery" value="${jdbc.validationQuery}" />
<property name="testOnBorrow" value="${jdbc.testOnBorrow}" />
</bean>

<!-- Hibernate session factory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="packagesToScan" value="com.lifesense.entity" />
</bean>

<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 配置事务，hibernate必须配置事务 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="modify*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="get*" read-only="true" />
<tx:method name="find*" read-only="true" />
<tx:method name="*" read-only="false" />
</tx:attributes>

</tx:advice>

<aop:config expose-proxy="true">
<!-- 只对业务逻辑层实施事务 -->
<aop:pointcut id="txPointcut"
expression="execution(* com.lifesense.service..*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" />
</aop:config>
</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

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

<import resource="classpath*:hibernate-config.xml" />
<!-- 注解扫描包 -->
<context:component-scan base-package="com.lifesense" />

<context:annotation-config />

<!-- 开启AOP注解扫描 -->
<aop:aspectj-autoproxy proxy-target-class="true" />

<!-- 启动JSON格式的配置 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<bean
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
</list>
</property>
</bean>

<!-- 定义视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

<!-- 支持文件上传 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8" />
<property name="maxUploadSize" value="1048576000" />
<property name="maxInMemorySize" value="40960" />
</bean>

</beans>

环境配置基本完毕我们测试一下，写了一个user类

package com.lifesense.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* 用户实体类
* @author Administrator
*
*/
@Entity
@Table
public class User {
//主键id
@Id
@GeneratedValue
private Integer id;

private String name;

private Integer age;

public Integer getId() {
return id;
}

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

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}

}

接下来是一个dao

package com.lifesense.dao.impl;

import org.springframework.stereotype.Repository;

import com.lifesense.dao.UserDao;
import com.lifesense.entity.User;

@Repository
public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao{

}

service

package com.lifesense.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.lifesense.dao.UserDao;
import com.lifesense.entity.User;
import com.lifesense.service.UserService;

@Service
public class UserServiceImpl implements UserService{

@Resource
private UserDao userDao;

/**
* 获取用户
* @param id 用户id
* @return
*/
public User getUser(Integer id){
return userDao.get(User.class, id);
}

/**
* 增加一个用户
* @param user 用户实体
*/
public void saveUser(User user){
userDao.save(user);
}

}

controller

package com.lifesense.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import com.lifesense.entity.User;
import com.lifesense.service.UserService;
/**
* 用户控制器
* @author Administrator
*
*/
@Controller
@RequestMapping("/user")
public class UserController {

@Resource
private UserService userService;

/**
* 获取用户
* @ResponseBody表示异步请求
* @return
*/
@RequestMapping(value="/get_user",method=RequestMethod.GET)
@ResponseBody
public User getUser(@RequestParam("id") Integer id){
return  userService.getUser(id);
}

/**
* 添加一个用户，这里使用json格式传递参数
* @param user
* @return
*/
@RequestMapping(value="/save_user",method=RequestMethod.POST)
@ResponseBody
public String saveUser(@RequestBody User user){
userService.saveUser(user);
return "success";
}

}

好了我们通过postman测试一下，OK
