java - 线程 main 中的异常 - maven 依赖

Question

public class BatchLauncherSpring {

    public static void main(String[] args) {

        ApplicationContext context = new ClassPathXmlApplicationContext(
                "application-context.xml");

        //////
    }
}

当我运行 main 方法时，出现 ClassNotFoundException。 Spring 依赖项是通过 Maven 添加的，这些依赖项在编译时解析。有很多类似的问题，但当代码打包为 jar 并在 eclipse 外部执行时，每个人似乎都遇到了问题。当我在 eclipse 本身中运行它时，我实际上遇到了这个问题。

这是pom文件

堆栈跟踪

java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Exception in thread "main"

这里有什么问题吗？谢谢!

你需要 spring-context 依赖快乐编码
