IDEA Maven 搭建 SSH（Spring + Spring MVC +Hibernate）教程
一、 创建Maven项目工程
- 新建项目，如下选择
- GroupId对应java包的接口
ArtifactID就是项目的唯一的标识符，实际对应项目的名称
3. 配置自己的Maven目录
然后next，Finnsh会生成如下工程项目
4. 创建java和resourse文件夹，并将java设置为Sources Root ，根据项目需要创建controller，service，dao等目录，将resourse设置为Resources Root。方法如下，右击文件夹然后选择。
二、搭建SSM框架
- 配置pom.xml 引入所需的包。 pom.xml内容如下
<?xml version="1.0" encoding="UTF-8"?>

- log4j.properties的配置
### 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 = [springmvc_hibernate][%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/springmvc_hibernate_demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate][%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/springmvc_hibernateerror.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [FundsManagerSys][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
### hibernate ###
log4j.logger.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
log4j.loggerorg.hibernate.type.descriptor.sql.BasicExtractor=TRACE
log4j.logger.org.hibernate.engine.QueryParameters=DEBUG
log4j.logger.org.hibernate.engine.query.HQLQueryPlan=DEBUG
三、配置Hibernate数据源
-
按照如下操作，我用的是mysql，所以选择mysql
-
点击Mysql后输入数据库名，用户名和密码，如果提示没有数据库驱动，点击下载即可。填写好后点击TestConnection测试是否连接成功。连接成功后点击apply后会在右方显示这个库的表及字段名，双击可查看表内数据
3. 点击File -> Project Structure -> Modules
4. 点击+ ，添加Hibernate
5. 点击右侧+ ，添加hibernate.cfg.xml。弹出框
选择Hibernate版本号，这里根据自己实际情况选择
-
此时左侧应该出现Persistence，点击打开
-
点击+ 添加Spring，并进行如下操作
这时Persistence中会出现sessionFaction
亦或者
在hibernate.cfg.xml中添加以下内容，则在Demo中会出现另一个名为hibernate.cfg.xml数据工厂
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:mysql://localhost:3306/managesystem</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.hbm2ddl.auto">update</property> <!--hibernate根据实体自动生成数据库表-->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <!--指定数据库方言-->
<property name="hibernate.show_sql">true</property> <!--在控制台显示执行的数据库操作语句-->
<property name="hibernate.format_sql">true</property> <!--在控制台显示执行的数据哭操作语句（格式）-->
<property name="hibernate.use_sql_comments">true</property>
<!-- DB schema will be updated if needed -->
<!-- <property name="hbm2ddl.auto">update</property> -->
</session-factory>
</hibernate-configuration>
- 右键单击 Demo
选择后弹窗, com.entity 是生成bean的目录，Entity是生成bean的后缀，下面是要生成bean的表。并且选中sessionFactory。点击ok
生成后如下图：（报错是因为表中未设置id主键，添加即可）
编写业务验证成功
