本文详细介绍了一个使用Spring4和Hibernate5的项目配置过程，包括pom.xml依赖配置、目录结构、Web.xml、applicationContext.xml及log4j配置等关键步骤，并提供了实体类和测试类的示例。

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。

5.spring--datasoucre.xml配置

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_user
public 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
	@Override
	public 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
	@Override
	public 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 {


@Test
public 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session

Transaction 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
