Java Spring Boot返回404

Question

Spring应用程序在从Eclipse运行时通常在嵌入式Tomcat服务器上运行，但当我将它部署到外部tomcat服务器(在Windows上)时，我得到了HTTP 404状态。

我清理了包，复制了目标文件夹war文件，在本地tomcat服务器上的tomcat webapp文件夹中，我重新启动tomcat，但是.

当我在带有端点http://localhost:8080/export/test/的postman中运行get方法时，没有找到404

Tomcat版本9

Java 11

TOMCAT管理器：

​

​

@SpringBootApplication
public class ExportApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ExportApplication.class);
    }
}

       @GetMapping("/test")

       public String currentUserName() {
              return "Hello";
       }

}

Answer 1

404意味着您所访问的url不是available.When --我们将代码部署在外部应用程序服务器上，它是从通常以项目名称开始的根上下文中提供的。您可以在日志中签入它所服务的上下文，然后附加它的.It将工作的其他端点。

Answer 2

可以在构建文件中使用finalName属性(pom.xml用于maven)

<finalName>export</finalName>
