我是drools中的新手,我正在尝试在Drools kie服务器6.4.0上执行一个简单的CEP规则.Final在Tomcat7上运行,但是当我尝试启动kie容器时出现以下错误。
[localhost-startStop-1] DEBUG KieModule Lookup. ReleaseId com.realtech:stdout:1.0-SNAPSHOT was not in cache, checking classpath
[localhost-startStop-1] DEBUG KieModule Lookup. ReleaseId com.realtech:stdout:1.0-SNAPSHOT was not in cache, checking maven repository
[localhost-startStop-1] ERROR Unable to build KieBaseModel:kbase1
Unable to Analyse Expression speed == 200:
[Error: unable to resolve method using strict-mode: com.realtech.flight.FlightStatus.speed()]
[Near : {... speed == 200 ....}]
^
[Line: 15, Column: 4] : [Rule name='flight print']
我的代码就像:
FlightStatus.drl
package com.realtech.flight;
//import com.realtech.flight.FlightStatus;
declare FlightStatus
@role(event)
end
rule "flight print"
no-loop true
when
$flight : FlightStatus( speed == 200 ) // over window:time(1m)
then
System.out.println("test");
end
FlightStatus.java
package com.realtech.flight;
/**
* This class was automatically generated by the data modeler tool.
*/
public class FlightStatus implements java.io.Serializable
{
static final long serialVersionUID = 1L;
public java.lang.Float speed;
public FlightStatus()
{
}
public java.lang.Float getSpeed()
{
return this.speed;
}
public void setSpeed(java.lang.Float speed)
{
this.speed = speed;
}
public FlightStatus(java.lang.Float speed)
{
this.speed = speed;
}
}
kie-workbench中的知识库设置: enter image description here
然后在kie-server中启动containter时出现异常。
但是当我删除声明时它会成功:
declare FlightStatus
@role(event)
end
或删除speed == 200
。
