java - 为什么没有找到休息终点？

Question

我有带有 spring-boot-starter-web 和 jpa 的 spring-boot 应用程序。本地运行正常。

然后，我构建 war 文件并尝试将其部署到 websphere 上。

我的项目有以下结构:

当在 websphere 上部署我的应用程序后，我加载像 ip:port/test 这样的根目录 - 显示来自 index.html 的起始页面。

但是，当尝试打开我的应用程序的其余部分时 - 显示 404 错误。对于来自客户端的发送请求，我尝试使用 postman 。

SpringBoot类是:

@ComponentScan({"data"})
@EntityScan(basePackages = {"data.model"})
@EnableJpaRepositories(basePackages = {"data.persistence"})
@EnableAutoConfiguration
@SpringBootApplication
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {

    }
}

如果没有 onstartup 方法，尝试启动时服务器上的 war 会失败。

Answer 1

这个简单的示例在 Liberty 上运行正常，如果您想将应用程序打包为 war 文件，请通过尝试运行它来验证您的设置是否正确，然后使用您需要的功能进行扩展。

@SpringBootApplication
@RestController
public class SpringBootLibertyApplication extends SpringBootServletInitializer {

    //@Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootLibertyApplication.class);
    }

    @RequestMapping("/hello")
    public String hello() {
        return "Hello from Spring Boot running on Liberty!";
    }

}

更新

下面是我使用的pom.xml。这不是最简单的，因为此外，您还配置了 Liberty 插件，它根据您的 server.xml 文件创建一个服务器，并将最终服务器打包为 jar 文件。我这样做是为了我自己的测试，所以你可以在 pom 中注释掉它。我没有任何 web.xml。

正如其他人已经评论的那样，您设置中的主要问题是您的 Application 类不在包的根目录，这会混淆所有 Spring 自动配置功能。因此，将您的 springboot.config.Application 移动到 data.Application。

pom.xml
