在Spring Boot应用程序中,Servlet可以通过添加`@ServletComponentScan`注解来自动注册。首先,需要在应用程序的类路径下创建一个类并使用`@WebServlet`注解来标记该类,如下所示:
```java
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@WebServlet(name = "myServlet", urlPatterns = "/hello")
public class MyServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
resp.getWriter().write("Hello, World!");
}
}
```
然后,在主应用程序类上添加`@ServletComponentScan`注解:
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
@SpringBootApplication
@ServletComponentScan
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
现在,您的Servlet将在应用程序启动时自动注册,并可通过`/hello`路径访问。
