我们可以使用 "spring-boot-starter-parent" 编写简单的启动应用程序吗?

Can we write simple boot application with using "spring-boot-starter-parent"

我已经开始研究 Spring-boot。我试图检查 "spring-boot-starter-parent" 是否必须作为父级包含在我们的 pom 中,xml 与否。

我尝试使用 "Spring-boot-starter-web" 作为父 pom,但它仍然给出一些有关过滤资源的错误,这可能是由于无法找出 application.properties。

在 pom 文件中必须有父项吗?

谢谢

是的,你可以,但你需要自己管理事情。 像 * 默认情况下为应用程序属性打开过滤, * 为用户项目应用更合理的默认值(测试配置等) * Spring 引导插件等

这是1.5.6的父pom文件

您可以看到它设置 spring-core、应用程序属性和其他常见的必需插件,这在任何 spring 应用程序中基本上都是必需的,

如果您不想要此默认内容,则无需添加入门级父级。 (这完全取决于您的应用程序,如果您不需要它们就离开它,但如果您需要它们,您不想自己管理所有东西,stater parent pom 是最好的朋友)

您将 spring-boot-starter-parent 作为父级,将 spring-boot-starter-web 作为依赖项;

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>

    <dependency>
        <groupId>org.springframework.boot</groupId>
