将 Spring-project 部署到 Glassfish (NoClassDefFoundError)

Question

我还是 Java EE 7 / Spring 的新手，正在尝试解决以下问题。我使用 Glassfish 4.1 和 JDK 1.8。

我使用项目方面 "Dynamic Web Module"、"Java"、"JavaScript", "JavaServer Faces" 如下:

index.xhtml

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

<h:form>
    <h:commandButton value="Submit Query" action="#{bean.login()}"></h:commandButton>
</h:form>
</html>

Bean.java

package springWeb;

import javax.enterprise.context.RequestScoped;
import javax.inject.Named;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;


@RequestScoped
@Named
public class Bean {

    //@Autowired
    private UserService userService;

    public String login(){
        AnnotationConfigApplicationContext context = 
                new AnnotationConfigApplicationContext(springConfiguration.class);
//      userService = (UserService)context.getBean("UserService");
//      userService.service();
        return "go.jsf";
    }
}

UserServiceImpl

package springWeb;


import org.springframework.stereotype.Component;

//@Component
public class UserServiceImpl implements UserService {

    @Override
    public void service() {
        System.out.println ("Service running...");
    }

}

按下命令按钮时，我收到以下错误消息：

javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/springframework/context/annotation/AnnotationConfigApplicationContext

root cause javax.faces.el.EvaluationException: java.lang.NoClassDefFoundError: org/springframework/context/annotation/AnnotationConfigApplicationContext

root cause java.lang.NoClassDefFoundError: org/springframework/context/annotation/AnnotationConfigApplicationContext

root cause java.lang.ClassNotFoundException: org.springframework.context.annotation.AnnotationConfigApplicationContext

这是什么原因，如何解决？（为了清楚起见，我已经注释掉了依赖注入。）

非常感谢您的帮助！

终于可以自己解决问题了。原因是我的代码所依赖的并且在编译时存在的 class 个文件在运行时没有找到。因此，我不得不复制七个缺失的库（例如 spring-context-4.2.0.RELEASE.jar、spring-expression-4.2.0.RELEASE.jar、spring- core-4.2.0.RELEASE.jar、spring-context-support-4.2.0.RELEASE.jar 等）到以下 Glassfish 库文件夹

C:\glassfish-4.1\glassfish4\glassfish\domains\domainXXXX\lib

您可以在网上轻松找到缺少的库，例如在 Maven 存储库中：http://repo1.maven.org/maven2/

帮助我理解这一点的相关帖子是： Why am I getting a NoClassDefFoundError in Java? 和 Maven vs. Eclipse Project Facets for Java EE 6
