Spring(21) 在 Spring Boot 中使用 Undertow 作为嵌入式服务器

import io.undertow.Undertow;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.undertow.UndertowServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.context.annotation.Bean;
 
@SpringBootApplication
public class UndertowExampleApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(UndertowExampleApplication.class, args);
    }
 
    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        UndertowServletWebServerFactory factory = new UndertowServletWebServerFactory();
        factory.addBuilderCustomizers(builder -> 
            builder.setServerOption(Undertow.BUFFER_POOL, new ByteBufferPoolBuilder().build())
        );
        return factory;
    }
}

这段代码演示了如何在Spring Boot应用程序中配置Undertow作为嵌入式服务器。通过定义一个webServerFactory的Bean，我们可以自定义Undertow的设置，例如设置缓冲池选项。这是一个简化的例子，实际应用中可以根据需要进行更多的自定义配置。
