在Spring Boot中创建自己的HTTP服务器可以使用内嵌的Tomcat、Jetty或Undertow等servlet容器来实现。以下是使用Tomcat作为例子:
1.添加Tomcat依赖
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>9.0.38</version>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
<version>9.0.38</version>
</dependency>
```
2.定义Servlet
```java
@WebServlet(name = "helloServlet", urlPatterns = { "/hello" })
public class HelloServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.getWriter().println("Hello, world!");
}
}
```
3.配置Servlet
```java
@Configuration
public class ServletConfig {
@Bean
public ServletRegistrationBean<HelloServlet> helloServletRegistrationBean() {
ServletRegistrationBean<HelloServlet> registrationBean = new ServletRegistrationBean<>(new HelloServlet(), "/hello");
registrationBean.setLoadOnStartup(1);
return registrationBean;
}
}
```
4.启动应用
```java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
5.访问Servlet
在浏览器中访问`http://localhost:8080/hello`即可看到输出"Hello, world!"。
以上就是使用Tomcat在Spring Boot中创建自己的HTTP服务器的步骤。其他servlet容器的使用方法类似,只需要更换对应的依赖和配置即可。
