Question

我正在为Spring的学校项目构建BlogPost。我可以到达我的index.jsp但是当我映射到其他控制器时，我得到了404.当我在@OnStartUp方法的WebApplicationInitializer中设置断点时，它永远不会到达。有谁知道我在这里失踪了什么？谢谢！

这是我的代码：

WebapplicationInitializer：

public class Initializer implements WebApplicationInitializer{
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        WebApplicationContext dispatcherContext = getContext();
        servletContext.addListener(new ContextLoaderListener(dispatcherContext));
        ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }

    private WebApplicationContext getContext(){
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.setConfigLocation("be.kdg.BlogPostSpringMVC.configuration");
        return context;
    }
}

的pom.xml：

Answer 1

将context.setConfigLocation("be.kdg.BlogPostSpringMVC.configuration")更改为context.scan("be.kdg.BlogPostSpringMVC.configuration")。

setConfigLocation（）用于指定spring配置文件的位置。

Answer 2

您的 pom.xml 文件缺少dependency:spring-context-support，这为我解决了问题

未达到WebApplicationInitializer
