java - Tomcat 9 上的 Spring Boot 无法映射 Controller (404)

Question

我使用 Java 11 在 tomcat9 上打包为 ROOT.war 的 Spring boot 应用程序似乎已成功加载，但无法映射 Controller 。我可以通过直接访问 .jsp 来查看每个页面，但我的 Controller 映射的 URL 没有 .jsp。如果我访问映射的 URL，我会得到标准的 404 页面。

此应用程序在本地运行，但在我的远程虚拟机上表达此行为。

我以前没有见过这个，并且在我的日志中找不到任何相关内容。我有另一个应用程序，其设置完全相同，运行良好。我错过了什么和/或下一步我应该尝试什么？

这是我的上下文文件:

<?xml version="1.0" encoding="UTF-8"?>
<Context antiResourceLocking="true" path=""/>

使用标准 Spring 应用程序设置:

@SpringBootApplication
public class Application extends SpringBootServletInitializer{

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

以及基本的请求映射和 ModelAndView 响应:

@RestController
public class PageController extends BasePageController {
    private static final Logger LOGGER = LoggerFactory.getLogger(PageController.class);

    @Autowired       private Configuration configuration;

    @Autowired
    private OrderManager orderManager;

    @RequestMapping(value = "/", method=RequestMethod.GET)
    public ModelAndView indexSlash(HttpServletRequest arg0, HttpServletResponse arg1) {

这在本地运行良好，对于具有相同设置的另一个应用程序也运行良好，这让我认为这是一些小版本问题。我使用的是 tomcat 9.0.34 和 Java 11.0.7。我的应用程序日志中没有任何内容。这是启动后我的 catalina.out 文件:

Answer 1

@RequestMapping 丢失。

@RestController
@RequestMapping("/page")
public class PageController extends BasePageController { }
