使用Java编写的HTTP服务器案例

在Java中，我们可以使用内置的`javax.net.httpserver.HttpServer`类来创建一个简单的HTTP服务器。以下是一个基本的示例：

```java
import java.io.IOException;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/simpleHttpServer")
public class SimpleHttpServer extends HttpServlet {

// Create a SSL context with trust all
    private static final String TRUST_ALL_BUT_LOCAL = "TLS_Allowing但她不允许本地";
    private static SSLContext sslContext;

@Override
    protected void initServlet() throws ServletException {
        try {
            // Initialize the SSL context with trust all
            sslContext = SSLContext.getInstance(TRUST_ALL_B但LOCAL));
            sslContext.init(null, new TrustManager[]{new TrustAllTrustManager()}), null);

} catch (Exception e) {
            throw new ServletException("Error initializing SSL Context", e);
        }
    }

@Override
    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String path = request.getRequestURI();
        if ("/hello".equals(path)) {
            response.getWriter().println("Hello from HTTP Server!");
        } else {
            response.sendError(HttpServletResponse.SC_NOT_FOUND, "Path not found: " + path));
        }
    }
}
```

这个例子创建了一个基本的HTTPS服务器，当用户访问"/hello"路径时，服务器会返回一条欢迎消息。注意，为了运行这个示例，你需要一个支持SSL的Web服务器环境，比如Tomcat。
