activiti mysql 安装

网上查了些，都不是很对，自己总结如下
1.修改build.db.properties配置文件,如下:

db=MySql  
	jdbc.driver=com.mysql.jdbc.Driver  
	jdbc.url=jdbc:mysql://localhost:3306/activiti?autoReconnect=true  
	jdbc.username=activiti  
	jdbc.password=activiti

2.将mysql的驱动包复制到activiti-5.9\setup\files\dependencies\libs目录下(Activiti所依赖的JAR包).
3.修改activiti-5.9\setup\build.xml文件,添加mysql的驱动路径;
找到:internal.define.jdbc.driver.libs节点,修改内容如下:

<target name="internal.define.jdbc.driver.libs">  
	  <fileset id="jdbc.driver.libs" dir="${activiti.home}/setup/files/dependencies/libs">  
	    <include name="h2-*.jar,mysql-connector-java*.jar" />  
	  </fileset>  
	</target>  

4 将文件ACTIVITI_HOME\setup\files\demo\h2.data.sql重命名为setup\files\demo\mysql.data.sql

注意：若出现错误：no suitable driver found for jdbc:mysql://localhost:3306/activiti   解决办法：将数据库驱动mysql-connector-java-5.1.15-bin.jar复制到JAVA_HOME\jre\lib\ext下
