那些遇到过的问题

为什么Spring Boot Web应用程序在启动后立即关闭？

Pau*_*ond 18 spring spring-boot

使用STS,如果我"Rest Service"使用最新的Spring Boot 导入Getting Started项目并选择"Run As Spring Boot App",它会启动,然后立即关闭.

查看调试日志,Spring出于某种原因决定该项目不是Web应用程序,但我不知道为什么.

如果我从Spring Boot切换1.1.1.RELEASE到1.0.1.RELEASE,项目按预期工作,并找到默认的Tomcat嵌入式服务器.

我在1.1.1发行说明中找不到任何暗示存在配置更改或其他内容的内容？

更新:重现和记录输出的步骤

我正在运行STS 3.6.0.M1和Spring 4.0.5以及Spring Boot 1.1.1.通过执行以下操作,我可以轻松地重现这一点:

  1. 导入REST服务入门应用程序.
  2. 选择"Run as Spring Boot Project"

  3. 这是输出:

    :: Spring Boot ::        (v1.1.1.RELEASE)

  4. 如果我编辑的POM并更改spring-boot-starter-parent到1.0.1.RELEASE它的靴子如预期.

更新2:添加了--debug命令的输出

我有同样的问题.为了使它工作,我不得不调整pom.xml并注释掉spring-boot-starter-tomcat工件的"提供"范围并更新依赖关系.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!--<scope>provided</scope>-->

现在它按预期启动!感谢其他一些让我走上正轨的答案.

执行包阶段时检查mvn日志,并确保将tomcat-embed-core jar分配到app app中.

我有同样的问题,我的spring-boot应用程序立即关闭,没有任何tomcat启动的痕迹,虽然我有<artifactId>spring-boot-starter-web</artifactId>我的pom.xml中包含的依赖项.这表明spring-boot无法将我的应用程序识别为Web应用程序.

尝试使用mvn clean install实用程序再次清理和打包我的应用程序,以验证tomcat库是否已打包到我的应用程序二进制文件/可部署中.发现以下问题:

我在我的本地仓库上的tomcat库已经损坏(由于某些未知原因),因为它没有被包含在maven包中.从我当地的maven repo中删除了相应的文件夹,让maven新下载.它现在就像一个魅力!
