java - 404 未在本地主机上找到或禁止

Question

“我从 localhost 访问我的应用程序时遇到问题。我通过 Eclipse 在 WildFly 服务器版本 17 中添加了该项目。

当我打开localhost:8080/vaadin-app/ui时，我收到404 not found。当我打开 localhost:8080/vaadin-app 时，我得到禁止。我哪里做错了？

问题是否与web.xml 文件有关？因为我意识到，web.xml 不存在。因此我手动创建了它 web.xml 。

pom.xml:

Answer 1

将您的 App.java 扩展自:

public class App extends SpringBootServletInitializer {

并在此处添加此方法:

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(App.class);
    }

最后，我建议您设置 war 名称。您可以通过将其添加到您的 pom.xml 中来实现:

<finalName>vaadin-app</finalName>
