使用Java写一个简易web服务器来替代nginx功能。

main:

    public static void main(String[] args) {
        ServerConfigLoader serverConfigLoader = Factory.serverConfigLoader();
        ServerConfig serverConfig = serverConfigLoader.getServerConfig();
        HttpServer httpServer = SimpleFileServer.createFileServer(new InetSocketAddress(Integer.parseInt(serverConfig.serverPort())),
                Path.of(serverConfig.contextLocation()), SimpleFileServer.OutputLevel.VERBOSE);
        httpServer.start();
    }

config:

public class ServerConfigLoader {

    private ServerConfig serverConfig;

    public ServerConfigLoader() {
        String configFileName = "server.properties";
        try (InputStream input = ServerConfigLoader.class.getClassLoader().getResourceAsStream(configFileName)) {
            Properties prop = new Properties();
            prop.load(input);
            this.serverConfig = new ServerConfig(prop.getProperty("server.port"), prop.getProperty("context.location"));
        } catch (IOException ex) {
            System.out.println("Start web server failed: " + ex.getLocalizedMessage());
            ex.printStackTrace();
        }
    }

    public ServerConfig getServerConfig() {
        return serverConfig;
    }
}


public record ServerConfig(String serverPort, String contextLocation) {
}

public class Factory {

    public static ServerConfigLoader serverConfigLoader() {
        return new ServerConfigLoader();
    }

}

到此,极简web server就写完了。
配置文件:
server.properties

server.port=8080
context.location=D:\\your-dictionary
