Question

我有一个弹簧控制器，它给出了404错误。

请找到以下控制器代码：

@RestController
@RequestMapping("/todo")
public class ToDoController {

private ToDoService toDoService;

private Logger logger = LoggerFactory.getLogger(ToDoController.class);

@Inject
public ToDoController(@Named("toDoService") ToDoService toDoService) {
    this.toDoService = toDoService;
}

@RequestMapping(value = "/{id}", method = RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
public ToDo getToDo(@PathVariable("id") int id) {
    logger.debug("Provider has received request to get person with id: " + id);
    return toDoService.getToDo(id);
}

@RequestMapping(value = "/add", method = RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
public void addToDo(@RequestBody ToDo toDo) {
    toDoService.addToDo(toDo);
}
}

web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我有我的弹簧配置XML（root-context.xml），如下所示。我为应用程序配置了H2内存数据库

我从UI调用ToDoController，但这给出了404错误。我已经验证了服务器控制台并确认应用程序已正确部署。

我真的很困惑。请帮我解决这个问题
