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

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"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    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="${jdbc.maxActive}" />
        <property name="maxIdle" value="${jdbc.maxIdle}" />
        <property name="maxWait" value="${jdbc.maxWait}" />
        <property name="removeAbandoned" value="${jdbc.removeAbandoned}" />
        <property name="removeAbandonedTimeout" value="${jdbc.removeAbandonedTimeout}" />
        <property name="logAbandoned" value="${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
