jBPM5.4-04:使用MySql数据库

1.下载MySql驱动放在安装目录/db/drivers/下。这里将名字修改为mysql.jar。

在MySql数据库中创建task和jbpm数据库。

2.修改db/jbpm-persistence-JPA2.xml和task-persistence-JPA2.xml,修改方式类似

将
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
或
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
修改为
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />

附：

Hibernate SQL Dialects (hibernate.dialect)

RDBMS Dialect

DB2	`org.hibernate.dialect.DB2Dialect`
DB2 AS/400	`org.hibernate.dialect.DB2400Dialect`
DB2 OS390	`org.hibernate.dialect.DB2390Dialect`
PostgreSQL	`org.hibernate.dialect.PostgreSQLDialect`
MySQL	`org.hibernate.dialect.MySQLDialect` org.hibernate.dialect.MySQL5Dialect
MySQL with InnoDB	`org.hibernate.dialect.MySQLInnoDBDialect`
MySQL with MyISAM	`org.hibernate.dialect.MySQLMyISAMDialect`
Oracle (any version)	`org.hibernate.dialect.OracleDialect`
Oracle 9i	`org.hibernate.dialect.Oracle9iDialect`
Oracle 10g	`org.hibernate.dialect.Oracle10gDialect`
Sybase	`org.hibernate.dialect.SybaseDialect`
Sybase Anywhere	`org.hibernate.dialect.SybaseAnywhereDialect`
Microsoft SQL Server	`org.hibernate.dialect.SQLServerDialect`
SAP DB	`org.hibernate.dialect.SAPDBDialect`
Informix	`org.hibernate.dialect.InformixDialect`
HypersonicSQL	`org.hibernate.dialect.HSQLDialect`
Ingres	`org.hibernate.dialect.IngresDialect`
Progress	`org.hibernate.dialect.ProgressDialect`
Mckoi SQL	`org.hibernate.dialect.MckoiDialect`
Interbase	`org.hibernate.dialect.InterbaseDialect`
Pointbase	`org.hibernate.dialect.PointbaseDialect`
FrontBase	`org.hibernate.dialect.FrontbaseDialect`
Firebird	`org.hibernate.dialect.FirebirdDialect`

3.修改task-service/resources/META-INF/persistence.xml

将
<properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
      <property name="hibernate.connection.driver_class" value="org.h2.Driver"/>
      <property name="hibernate.connection.url" value="jdbc:h2:tcp://localhost/runtime/task" />
      <property name="hibernate.connection.username" value="sa"/>
      <property name="hibernate.connection.password" value=""/>
      <property name="hibernate.connection.autocommit" value="false" />
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="create" />
      <property name="hibernate.show_sql" value="false" />
    </properties>
修改为
<properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/task" />
      <property name="hibernate.connection.username" value="用户名"/>
      <property name="hibernate.connection.password" value="密码"/>
      <property name="hibernate.connection.autocommit" value="false" />
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="create" />
      <property name="hibernate.show_sql" value="false" />
    </properties>

4.修改db/mysql_module.xml中jar的名称为mysql.jar,与db/drivers中的jar名称对应。

<resources>
     <resource-root path="mysql.jar"/>
</resources>

5.使用的是Jboss7，修改安装目录下的standalone.xml

将
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
            <datasources>
                <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
                    <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
                    <driver>h2</driver>
                    <security>
                        <user-name>sa</user-name>
                        <password>sa</password>
                    </security>
                </datasource>
                <datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="H2DS" enabled="true" use-java-context="true" use-ccm="true">
                    <connection-url>jdbc:h2:~/jbpm</connection-url>
                    <driver>h2</driver>
                    <pool>
                        <min-pool-size>1</min-pool-size>
                        <max-pool-size>4</max-pool-size>
                        <prefill>false</prefill>
                        <use-strict-min>false</use-strict-min>
                        <flush-strategy>FailingConnectionOnly</flush-strategy>
                    </pool>
                    <security>
                        <user-name>sa</user-name>
                    </security>
                    <validation>
                        <check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
                        <validate-on-match>false</validate-on-match>
                        <background-validation>false</background-validation>
                    </validation>
                </datasource>
                <drivers>
                    <driver name="h2" module="com.h2database.h2">
                        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>
        </subsystem>
修改为
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
            <datasources>
                <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
                    <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
                    <driver>h2</driver>
                    <security>
                        <user-name>sa</user-name>
                        <password>sa</password>
                    </security>
                </datasource>
                <datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="H2DS" enabled="true" use-java-context="true" use-ccm="true">
                    <connection-url>jdbc:mysql://localhost:3306/jbpm</connection-url>
                    <driver>mysql</driver>
                    <pool>
                        <min-pool-size>1</min-pool-size>
                        <max-pool-size>4</max-pool-size>
                        <prefill>false</prefill>
                        <use-strict-min>false</use-strict-min>
                        <flush-strategy>FailingConnectionOnly</flush-strategy>
                    </pool>
                    <security>
                        <user-name>用户名</user-name>
			<password>密码</password>
                    </security>
                    <validation>
                        <check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
                        <validate-on-match>false</validate-on-match>
                        <background-validation>false</background-validation>
                    </validation>
                </datasource>
                <drivers>
                    <driver name="mysql" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>
        </subsystem>

6.修改安装目录下的build.properties，将数据库的配置从H2，改为MySql

# default is H2
#db.name=h2
#db.driver.jar.name=${db.name}.jar
#db.driver.download.url=http://repo1.maven.org/maven2/com/h2database/h2/${H2.version}/h2-${H2.version}.jar
#other options are mysql
  db.name=mysql
  db.driver.module.prefix=com/mysql
  db.driver.jar.name=${db.name}.jar
  db.driver.download.url=https://repository.jboss.org/nexus/service/local/repositories/central/content/mysql/mysql-connector-java/5.1.18/mysql-connector-java-5.1.18.jar

7.修改/lib/jbpm-human-task-war-5.4.0.Final-EE6.war/WEB-INF/classes/META-INF/persistence.xml文件中的 hibernate.dialect

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>

8.修改/lib/jbpm-gwt-console-server-5.4.0.Final-EE6.war/ WEB-INF/classes/META-INF/persistence.xml 文件中的 hibernate.dialect和 hibernate.hbm2ddl.auto。

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />

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

9.修改build.xml

在
 <java classname="org.jbpm.DemoTaskService" fork="true">  
      <classpath>
        <pathelement path="${install.home}/task-service/target"/>
        <path refid="classpath.human.task" />
      </classpath>
    </java>

中加
<sysproperty key="jbpm.user.group.mapping" value="file:///F:/PDF/jbpm/jbpm-installer/jboss-as-7.1.1.Final/standalone/configuration/roles.properties"/> 
变为
 <java classname="org.jbpm.DemoTaskService" fork="true">  
	  <sysproperty key="jbpm.user.group.mapping" value="file:///F:/PDF/jbpm/jbpm-installer/jboss-as-7.1.1.Final/standalone/configuration/roles.properties"/> 
      <classpath>
        <pathelement path="${install.home}/task-service/target"/>
        <path refid="classpath.human.task" />
      </classpath>
    </java>

根据你的实际目录修改

10.在CMD中到你的安装目录下，运行

ant install.demo
或
ant install.demo.noeclipse

11.运行

ant start.human.task

创建task数据库表 ,创建完成后按Ctrl+C，再按退出创建。

12.运行

ant start.jboss

启动，会创建jbpm数据库表。

启动成功后再运行

ant stop.jboss

成功关闭后修改安装目录下\jboss-as-7.1.1.Final\standalone\deployments\jbpm-gwt-console-server.war\ WEB-INF/classes/META-INF/persistence.xml 文件中的 hibernate.hbm2ddl.auto。

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