Question

正如标题所说，当我将我的春季启动战争从eclipse部署到tomcat时它部署得很好，但每当我尝试访问它时，我都会收到404错误。我尝试了多件事无济于事。我怀疑它与上下文有关，但无法找到一个好的解决方案。该项目在localhost上使用嵌入式tomcat工作正常。关于如何解决这个问题的任何建议？

Application.java

package com.beta;

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.context.web.SpringBootServletInitializer; 
import org.springframework.context.annotation.Import; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

@SpringBootApplication 
@EnableJpaRepositories 
@Import(RepositoryRestMvcConfiguration.class) 
public class Application extends SpringBootServletInitializer {

@Override   
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(Application.class);    
}       

public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        } }

我查看过的tomcat日志不是正确的日志，这里是我收到错误的正确日志。不确定为什么时机成熟。

Answer 1

感谢所有帮助。我终于弄明白了这个问题。我的服务器上的tomcat使用java 6，而spring启动应用程序使用的是java 8.我在我的ubuntu服务器上导航到etc / default / tomcat7，并将JAVA_HOME = / usr / lib / jvm / section更改为java 8而不是6

你最近在你的lib中还有一些tomcat jar你是否已经将包装从jar（嵌入式tomcat）更改为war？你有没有试过

mvn clean package

重新创建一个干净的战争文件？

spring boot war部署到tomcat会出现404错误
