spring不断获得java。lang.ClassNotFoundException:com。太阳面孔。配置。配置侦听器

Question

我正在努力解决以下例外情况：

我正在使用maven并在下面添加依赖项来解决这个问题，但并没有得到结果，仍然面临同样的问题

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.1</version>
</dependency>

<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>jstl-api</artifactId>
    <version>1.2</version>
    <scope>compile</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

我已经添加了maven依赖项。对于Spring和Hibernate，我添加了所有必需的依赖项

Answer 1

如果错误是说找不到该类，那么实际上是说JVM无法加载该类，因为JVM无法在类路径中找到该类

然后您需要使用maven再次构建您的项目，以便创建。JVM的类文件

或者在此之前，尝试再次将项目依赖项从远程maven存储库拉入本地maven存储库，然后执行maven构建项目以填充。类文件

希望这有帮助

Answer 2

我认为问题不在于你的依赖性。我也是春天的新手，但我认为这可能会帮助你：

@Configuration
public class SpringWebAppInitializer implements WebApplicationInitializer{

     @Override
     public void onStartup(ServletContext sc) throws ServletException {
         AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
         context.register(ApplicationContextConfig.class);

         ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", new DispatcherServlet(context));
         dispatcher.setLoadOnStartup(1);
         dispatcher.addMapping("/");
     }
}
