在没有 web.xml 的情况下将 Spring 应用程序部署到 Tomcat

Question

我已经成功测试了带有嵌入式 TOMCAT 的 war 文件，它工作正常。现在我想将它部署到 TOMCAT，但我不断收到 404 错误。

我在浏览器上导航到的URL是 http://localhost:9999/springrest/demo/users/all

我的TOMCAT使用端口9999

我的JRE_HOME版本是1.8.0_261

我的pom.xml有1.8

TOMCAT 经理显示该应用程序为运行

我的控制器代码如下

  @RestController
  @RequestMapping(path="/demo") 
  public class UserController {

  @Autowired 
  private UserRepository userRepository;

  @GetMapping(path="/users/all")
  public @ResponseBody Iterable<User> getAllUsers() {
  // This returns a JSON or XML with the users
  return userRepository.findAll();
  }

}

我的pom.xml

Answer 1

你是否通过实现SpringBootServletInitializer接口初始化了Tomcat需要的Servlet上下文？

@SpringBootApplication
public class SpringBootTomcatApplication extends SpringBootServletInitializer {
}

详情请参考这个link:Deploy a Spring Boot WAR into a Tomcat Server

Answer 2

将我的 Apache Tomcat 版本 更改为 Apache Tomcat 8.5.58 并且效果很好. Springboot 横幅甚至在运行ning catalina.bat 运行
