目前世面上中文的KIE DROOLS Workbench（JBOSS BRMS）的教程几乎没有，有的也只有灵灵碎碎的使用机器来翻译的（翻的不知所云）或者是基于老版本的JBOSS Guvnor即5.x的一些教程，而且这些教程都是”缺胳膊少腿“的，初学者看后不知道它到底在干吗？能干吗？能够解决自己系统中什么问题。

所以笔者自己写了几个例子，把整个最新的英文版的KIE DROOLS 6.3.0.Final的官方教程给串了起来，用于供读者使用并以此来作为入门以及相关SOA理念的推广的第一步。

本教程共分为”三“集。

开始安装

2. 打开eclipse后按照Help->install new software输入以下地址

http://download.jboss.org/drools/release/6.3.0.Final/org.drools.updatesite/

<properties>
      <!--property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/-->
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="update"/>
      <property name="hibernate.show_sql" value="false"/>
      <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup"/>
      <!-- BZ 841786: AS7/EAP 6/Hib 4 uses new (sequence) generators which seem to cause problems -->
      <property name="hibernate.id.new_generator_mappings" value="false"/>
 </properties>

bitronix.tm.serverId=tomcat-btm-node0
bitronix.tm.journal.disk.logPart1Filename=${btm.root}/work/btm1.tlog
bitronix.tm.journal.disk.logPart2Filename=${btm.root}/work/btm2.tlog
bitronix.tm.resource.configuration=${btm.root}/conf/resources.properties

7. 在tomcat的conf目录下增加一个文件名为：btm-config.properties的文件

resource.ds1.className=bitronix.tm.resource.jdbc.lrc.LrcXADataSource
resource.ds1.uniqueName=jdbc/jbpm
resource.ds1.minPoolSize=10
resource.ds1.maxPoolSize=20
resource.ds1.driverProperties.driverClassName=com.mysql.jdbc.Driver
resource.ds1.driverProperties.url=jdbc:mysql://192.168.0.101:3306/drools?useUnicode=true&characterEncoding=UTF-8
resource.ds1.driverProperties.user=kie
resource.ds1.driverProperties.password=aaaaaa
resource.ds1.allowLocalTransactions=true

8. 在tomcat的conf目录下修改context.xml

<Resource name="jdbc/jbpm" auth="Container" type="javax.sql.DataSource" 
			driverClassName="com.mysql.jdbc.Driver" 
    	url="jdbc:mysql://192.168.0.101:3306/drools?useUnicode=true&characterEncoding=UTF-8" 
    	username="kie" 
    	password="aaaaaa" 
    	maxActive="20" 
    	maxIdle="1" 
      maxWait="5000" />

<Valve className="org.kie.integration.tomcat.JACCValve" /> 

<user username="tomcat" password="tomcat" roles="admin,manager,manager-gui"/>

export CATALINA_HOME="/opt/tomcat1"
export CATALINA_OPTS="-Dbtm.root=$CATALINA_HOME     	-Dbitronix.tm.configuration=$CATALINA_HOME/conf/btm-config.properties     	-Djbpm.tsr.jndi.lookup=java:comp/env/TransactionSynchronizationRegistry    	-Djava.security.auth.login.config=$CATALINA_HOME/webapps/kie-drools/WEB-INF/classes/login.config     	-Dorg.jboss.logging.provider=jdk"
export JAVA_OPTS="-d64 -server -showversion -Xms1024m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:CICompilerCount=8 -XX:+UseCompressedOops -XX:-DontCompileHugeMethods -Xss256k -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:MaxTenuringThreshold=31 -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:+UseFastAccessorMethods -Djava.awt.headless=true -XX:+UseCMSInitiatingOccupancyOnly -XX:+UseGCOverheadLimit -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:MaxGCPauseMillis=200 -Dorg.kie.demo=false"  

打开一个IE，输入如下地址：http://192.168.0.101:8080/kie-drools即可看到kie-drools的主界面了

package org.sky.threshholdrulz;

public class PaymentInfo implements java.io.Serializable {

static final long serialVersionUID = 1L;

public PaymentInfo() {
}

private int moneyAmount = 0;
private String decisionPath = "";

public void setMoneyAmount(int amount) {
this.moneyAmount = amount;
}

public int getMoneyAmount() {
return this.moneyAmount;
}

public void setDecisionPath(String path) {
this.decisionPath = path;
}

public String getDecisionPath() {
return this.decisionPath;
}
}

package org.sky.threshholdrulz;

no-loop

rule "approval decision by manager"
    when
        m : PaymentInfo( moneyAmount>5000 );
    then
         modify (m) { setDecisionPath("GM") };
end

rule "approval decision by general manager"
    when
        m : PaymentInfo( moneyAmount<=5000 );
    then
         modify (m) { setDecisionPath("M") };
end
