我正在将Spring与Drools集成在一起，但是全局变量存在问题。当我将代码作为Java应用程序运行时，没有问题，但是，如果我将代码作为Spring应用程序运行，我得到了全局预期的com.package.sameobj非法类，发现com.package.sameobj错误
作为Java应用程序运行，一切正常：
package com.softarts.app;
import java.util.Collection;
import java.util.Iterator;
import java.util.List;
import java.util.ListIterator;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import com.softarts.app.logic.Embargo;
import com.softarts.app.logic.Entidad;
import com.softarts.app.services.SystemExpertConfiguration;
import com.softarts.app.services.SystemExpertService;
public class main {
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext context = new AnnotationConfigApplicationContext(SystemExpertConfiguration.class);
SystemExpertService systemExpertService= (SystemExpertService) context.getBean(SystemExpertService.class);
String s=systemExpertService.calculateEmbargo();
System.out.println(s);
}
}
以Spring Application身份运行时，出现此错误
java.lang.RuntimeException: Illegal class for global. Expected [com.softarts.app.systemexpert.datos.DataAmount], found [com.softarts.app.systemexpert.datos.DataAmount].
