Maven整合Spring4和Hibernate5

1.先贴出来pom.xml的配置，该文件里面Log4j，Junit4需要有，Hibernate5和Spring4配置中前三个jar包必须有，其他的jar包根据个人情况删减。

2.目录结构图

3.Web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" 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/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name>xxx</display-name><welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list><!-- 监听器Spring,web容器启动的时候，会自动装配Spring的位于/WEB-INF/下的applicationContext.xml -->     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>      <!-- 定位applicationContext.xml的物理位置，因为可能要修改 -->     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:applicationContext.xml</param-value>     </context-param></web-app>

4.applicationContext.xml配置

<?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:c="http://www.springframework.org/schema/c"    xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"    xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd    http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-4.1.xsd    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">    <!--数据源配置 -->    <!--     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> --><!-- <property name="driverClassName" value="com.mysql.jdbc.Driver"/> --><!--         <property name="url" value="jdbc:mysql://localhost:3306/strategy"/> --><!--         <property name="username" value="root"/> --><!--         <property name="password" value="123456"/> --><!-- </bean> --><bean id="strategyBean" class="com.strategy.beans.Strategy"><property name="name" value="张三"/></bean></beans>

5.spring--datasoucre.xml配置

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd                        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd                       http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"><!-- 设置为close使Spring容器关闭同时数据源能够正常关闭，以免造成连接泄露 --><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="url" value="jdbc:mysql://localhost:3306/strategy" /><property name="username" value="root" /><property name="password" value="123456" /><property name="defaultReadOnly" value="false" /><!-- 设置为只读状态，配置读写分离时，读库可以设置为true在连接池创建后，会初始化并维护一定数量的数据库安连接，当请求过多时，数据库会动态增加连接数， 当请求过少时，连接池会减少连接数至一个最小空闲值 --><property name="initialSize" value="5" /><!-- 在启动连接池初始创建的数据库连接，默认为0 --><property name="maxActive" value="15" /><!-- 设置数据库同一时间的最大活跃连接默认为8，负数表示不闲置 --><property name="maxIdle" value="10" /><!-- 在连接池空闲时的最大连接数，超过的会被释放，默认为8，负数表示不闲置 --><property name="minIdle" value="2" /><!-- 空闲时的最小连接数，低于这个数量会创建新连接，默认为0 --><property name="maxWait" value="10000" /><!-- 连接被用完时等待归还的最大等待时间，单位毫秒，超出时间抛异常，默认为无限等待 --></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource"><ref bean="dataSource" /></property><property name="hibernateProperties"><props><!-- MySQL的方言 --><prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop><prop key="javax.persistence.validation.mode">none</prop><!-- 必要时在数据库新建所有表格 --><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.show_sql">true</prop><prop key="current_session_context_class">thread</prop><!-- <prop key="hibernate.format_sql">true</prop> --></props></property><!-- 配置需要扫描的包路径，在该包下，所有的类注解配置都会被扫描 --><property name="packagesToScan" value="com.strategy.jpa" >    </property></bean></beans>

6.log4j2.xml配置

<?xml version="1.0" encoding="UTF-8"?>  <Configuration status="info">      <Appenders>          <Console name="Console" target="SYSTEM_OUT">              <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />          </Console>      </Appenders>      <Loggers>          <Root level="info">              <AppenderRef ref="Console" />          </Root>      </Loggers>  </Configuration>  

7.log4j.properties配置

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

主要的配置就是上述几个，下面为实体类和测试类：

package com.strategy.jpa;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;@Entity//声明当前类为hibernate映射到数据库中的实体类@Table(name = "t_user")//声明在数据库中自动生成的表名为t_userpublic class User {@Id//声明此列为主键,作为映射对象的标识符@GeneratedValue(strategy = GenerationType.AUTO)private Integer id;private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}//重写hashcode方法提高比较效率@Overridepublic int hashCode() {final int prime = 31;int result = 1;result = prime * result + ((id == null) ? 0 : id.hashCode());result = prime * result + ((name == null) ? 0 : name.hashCode());return result;}//重写equals比较对象相等@Overridepublic boolean equals(Object obj) {if (this == obj)//如果地址引用相同，直接判断为相等return true;if (obj == null)//如果目标对象为null,直接判断不等return false;if (getClass() != obj.getClass())//两者类不一致return false;User other = (User) obj;if (id == null) {if (other.id != null)return false;} else if (!id.equals(other.id))//判断两者id是否都存在且相等return false;if (name == null) {if (other.name != null)return false;} else if (!name.equals(other.name))//判断两者名字是否都存在且相等return false;return true;}}

测试类：

package xxx.com.strategy.test;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.strategy.jpa.User;public class test {@Testpublic void test2(){ApplicationContext ac = new ClassPathXmlApplicationContext("spring-datasource.xml");SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");Session session = sessionFactory.openSession();//从会话工厂获取一个sessionTransaction transaction = session.beginTransaction();//开启一个新的事务User user = new User();user.setName("hello spring");session.save(user);transaction.commit();//提交事务}}

ok，Spring4整合Hibernate5的基本内容就是上述这些，顺便要说一下，项目如果需要用到的js等，最好放到resouces文件夹下。

网上整合的乱七八糟，不是Log4j错误，就是Spring错误，用个新点版本的找都找不到。。。。难受
