春季靴子战争文件不能在Tomcat上工作

Question

他，

这一直困扰着我一段时间，所以我做了一个MWE。我创建了一个Spring-Boot应用程序，将其转换为war文件。建立与maven。我可以在本地机器上运行它，没问题，但是在我的主机的机器上每次都会崩溃。堆栈跟踪：

将boot-file只是

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.context.web.SpringBootServletInitializer; 

@SpringBootApplication 
public class Boot extends SpringBootServletInitializer { 
    public static void main(final String[] args) { 
     SpringApplication.run(Boot.class, args); 
    } 

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

并完成的pom.xml：http://pastebin.com/bKZt9tWy

奇怪的是：没有application.properties在任何地方机。所以...非常感谢每一个答案，甚至只是指针。

Answer 1

问题是您的用户对文件夹./config/application.properties没有读取权限。

默认情况下，Spring引导尝试从某些位置加载属性，而./config/application.properties是其中一个位置。请参阅the docs

简单的修复方法是将读取授予用户。另一种方法是覆盖文档中指定的默认位置。
