我正试图在tomcat8上部署一个spring boot rest控制器。当我直接从eclipse运行它时，它工作得很好。但是当部署到Tomcat8时，我得到一个404错误。
我遵守了这些指示(https://www.baeldung.com/spring-boot-war-tomcat-deploy)到处搜索，但似乎什么都没用。
这是我的控制器：

import java.util.Collection;
import java.util.stream.Collectors;
import java.util.stream.IntStream;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TomcatController {

    @GetMapping("/hello")
    public Collection<String> sayHello() {
        return IntStream.range(0, 10)
          .mapToObj(i -> "Hello number " + i)
          .collect(Collectors.toList());
    }

}

这是我的申请表：

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

@SpringBootApplication
public class SsoApplication extends SpringBootServletInitializer {

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

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

下面是我的pom.xml：

任何帮助都将不胜感激。总而言之，当我用localhost:8080/hello“，它起作用了。当我部署到tomcat 8并使用localhost:8080/sso/hello“，我得到一个404。
