Question

package springdemo4;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class HelloSpringApp {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        Coach theCoach = context.getBean("myCoach",Coach.class);
        System.out.println(theCoach.getDailyFortune());
        System.out.println(theCoach.getDailyWorkout());
        context.close();

    }

}

我运行它，然后它说:

Error occurred during initialization of boot layer java.lang.module.FindException: Unable to derive module descriptor for C:\Users\ngoch\eclipse-workspace\springdemo4\libs\spring-context-indexer-5.1.9.RELEASE-sources.jar Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class org.springframework.context.index.processor.CandidateComponentsIndexer not in module

请帮忙

我在 Eclipse IDE 上遇到了同样的问题。我错误地在Modulepath下添加了spring jar文件。它应该在 Classpath 下(Properties > Java Build Path > Classpath > addJARs)。
