The type org.springframework.context.support.AbstractApplicationContext cannot be resolved

在 myeclipse中，使用 jdk6和7，并使用 spring-framework-5.0.2.RELEASE 时，编写代码：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MainApp {
   public static void main(String[] args) {
       ApplicationContext ac = new ClassPathXmlApplicationContext("Beans.xml");
      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
      obj.getMessage();
       
       
   }
}

总会报错：

The type org.springframework.context.support.AbstractApplicationContext cannot be resolved. It is indirectly referenced from
required .class files

以及

Type mismatch: cannot convert from ClassPathXmlApplicationContext to ApplicationContext

 

原因， spring-framework-5.0.2.RELEASE  需要使用 jdk8。
