在春靴中，我不能排除嵌入式雄猫

Question

我已经排除了嵌入的依赖项，但它总是以tomcat而不是underflow开头。我在这个问题上疯了。希望有人能帮我，非常感谢。我试过很多方法，但都不起作用。这是IDEA的原因吗？任何答案都是有用的。

Answer 1

谢谢大家。我添加了以下代码。它是有效的。

@Bean
public  UndertowServletWebServerFactory
undertowServletWebServerFactory() {
UndertowServletWebServerFactory factory = new 
UndertowServletWebServerFactory();
factory.addBuilderCustomizers(builder -> 
builder.setServerOption(UndertowOptions.ENABLE_HTTP2, true)                 .setServerOption(UndertowOptions.HTTP2_SETTINGS_ENABLE_PUSH,true));
return factory;
}
