Tomcat上的Spring应用程序- context路径/web-customer-rest-demo下的应用程序无法

Question

又是《雄猫》。我试图在Tomcat上运行一个Spring项目，构建阶段很好，但我一直得到这个部署错误。配置文件的内容如下:MySpringMvcDispatcherServletInitializer.java

package com.luv2code.springdemo.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
// TODO Auto-generated method stub
return null;
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { DemoAppConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}

"看起来你的帖子主要是代码;请补充更多的细节。我想知道这是谁编的?

Answer 1

缺失的类org.springframework.core.metrics.ApplicationStartup属于spring-core，在5.3版本中出现。

从你的pom.xml来看，你有版本5.3.9的spring-context，它依赖于同一版本的spring-core。但是，Maven必须选择5.0.6.RELEASE版本，这是您的其他Spring依赖项的依赖项。
