在测试使用工作台创建的示例规则时，我遇到了以下问题。
附模型、规则和eclipse测试场景。
问题：getCity 总是返回 null
在工作台中创建的等效模型代码。
该规则检查客户 ID 是否小于 100。如果客户 ID 小于 100，则城市设置为伦敦。
package com.sample;
public class CustomerDetails implements java.io.Serializable
{
static final long serialVersionUID = 1L;
private int customerID;
private java.lang.String city;
public CustomerDetails()
{
}
public java.lang.String getCity()
{
return this.city;
}
public void setCity(java.lang.String city)
{
this.city = city;
}
public int getCustomerID()
{
return this.customerID;
}
public void setCustomerID(int customerID)
{
this.customerID = customerID;
}
public CustomerDetails(int customerID, java.lang.String city)
{
this.customerID = customerID;
this.city = city;
}
}
eclipse中用于测试的代码
package com.sample;
import java.io.File;
import java.math.BigInteger;
import java.util.Scanner;
import org.drools.compiler.kproject.ReleaseIdImpl;
import org.kie.api.KieServices;
import org.kie.api.builder.KieScanner;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession;
import org.kie.api.runtime.StatelessKieSession;
public class Testing {
public static void main(String[] args)
{
String url = "http://localhost:8080/kie-drools-wb-distribution-wars-6.2.0.Final-jboss-as7/maven2/TestProject/demo/TestProject/1.0/TestProject-1.0.jar";
ReleaseIdImpl releaseId = new ReleaseIdImpl("demo", "TestProject", "LATEST");
KieServices kieServices = KieServices.Factory.get();
kieServices.getResources().newUrlResource(url);
KieContainer kieContainer = kieServices.newKieContainer(releaseId);
KieScanner kieScanner = kieServices.newKieScanner(kieContainer);
kieScanner.scanNow();
Scanner scanner = new Scanner(System.in);
System.out.println("kieContainer.getKieBaseNames() "+kieContainer.getKieBaseNames());
KieSession newKieSession =kieContainer.newKieSession("session1");
// StatelessKieSession kSession = kieContainer.newStatelessKieSession();
CustomerDetails testdetails=new CustomerDetails();
//BigInteger lcustomerID = BigInteger.valueOf(20);
testdetails.setCustomerID(10);
newKieSession.insert(testdetails);
newKieSession.fireAllRules();
//kSession.execute(testdetails);
System.out.println("testdetails.getCustomerID()= " +testdetails.getCustomerID());
System.out.println("City= " +testdetails.getCity());
// while (true) {
//runRule(kieContainer);
// System.out.println("Press enter in order to run the test again....");
// scanner.nextLine();
//}
}
}
