java - 无法使用路径映射 Controller

Question

我有这个简单的 java Spring Boot 项目，没有任何 bean 或持久性。我创建了多个包以按功能分隔类。

我读到 Controller 必须在初始包 NameApplication.java 中。但是，我在端口 8080 上启动项目并放置下一个 url localhost:8080/hello/grettings show me Whitelabel Error Page 但我放置 localhost:8080 并加载 index.html

为什么不起作用？

@Controller
@RequestMapping("/hello")
public class BasicController {

    @GetMapping(path = {"/grettings", "/helloworld"})
    public String grettings() {
        return "index";
    }
}

包结构

Answer 1

CursoSpringApplication 是应用程序的起点。启动时，它会搜索@Controller、@Service、@Repository 和@Component 等组件。通常建议您将主应用程序类放在其他类之上的根包中。所以这个CursoSpringApplication类应该放在最外层的包中。将 com.globalomnium.axis.maps 更改为 com.globalomnium.axis

示例结构

com
 +- example
     +- myapplication
         +- Application.java
         |
         +- customer
         |   +- Customer.java
         |   +- CustomerController.java
         |   +- CustomerService.java
         |   +- CustomerRepository.java
         |
         +- order
             +- Order.java
             +- OrderController.java
             +- OrderService.java
             +- OrderRepository.java
