JBPM4.4的搭建与配置

1：下载插件安装包。进行eclipse插件的安装。如下所示

?

2：安装完成之后，会看到如图所示，表示安装成功

如此则表示安装完成

?

3：配置项目

将上述的文件添加到项目中。

?

4：修改jbpm.hibernate.cfg.xml

?

?

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>

		<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
		<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="hibernate.connection.url">jdbc:mysql:///jbpm4_mysql?characterEncoding=UTF-8</property>
		<property name="hibernate.connection.username">root</property>
		<property name="hibernate.connection.password">123456</property>
		<!-- 第一次运行项目的时候，用create-drop，这样可以自动在数据库中创建表 -->
		<!-- <property name="hibernate.hbm2ddl.auto">create-drop</property> -->
		<property name="hibernate.hbm2ddl.auto">update</property>
		<!-- <property name="hibernate.format_sql">true</property> -->

		<mapping resource="jbpm.repository.hbm.xml" />
		<mapping resource="jbpm.execution.hbm.xml" />
		<mapping resource="jbpm.history.hbm.xml" />
		<mapping resource="jbpm.task.hbm.xml" />
		<mapping resource="jbpm.identity.hbm.xml" />

	</session-factory>
</hibernate-configuration>

??注释：

?

<property name="hibernate.hbm2ddl.auto"></property>

?

这个属性标签中有四个参数可以写，这四个参数是对数据库中插入的进行不同的操作，分别为：

（1）create-drop

（2）create

（3）update

（4）validate

下面分别来介绍他们的作用以及对数据库中的影响

(1)<property name="hibernate.hbm2ddl.auto"> create-drop </property>

create-drop:表示在hebarinate初始化时创建表格,程序运行结束的时候会删除相应的表格，在实际项目中不用

?

(2)<property name="hibernate.hbm2ddl.auto">create</property>

在hibernate初始化时会创建表格，在运行结束之后不删除表格，而是在下一次运行的时候如果有旧的删掉，没有旧的，重新建表格

?

(3)<property name="hibernate.hbm2ddl.auto">update</property>

只是根据映射文件去和数据库中的表对应起来，如果不一致，就更新表的结构

?

(4)<property name="hibernate.hbm2ddl.auto">validate</property>

校验映射文件和数据库中的表是不是能对应起来，不能对应报错，实际中常用

?

5：MAVEN配置
