在 Tomcat 服务器上部署 Spring Boot War 文件时出错答案

【问题标题】：Error while deploying Spring boot war file on Tomcat server在 Tomcat 服务器上部署 Spring Boot War 文件时出错
【发布时间】：2018-02-22 23:29:48
【问题描述】：

我有一个 Spring Boot 应用程序，我正在尝试将它部署在 Tomcat 服务器上。当我在 Eclipse 中本地运行应用程序时，它成功部署。但是当我尝试在 Linux Tomcat 服务器上部署时。它失败。我不确定配置有什么问题。我试图将war文件放在tomcat webapps文件夹下并运行startup.bat文件。但它继续运行日志跟踪。请建议我应该尝试什么。

【问题讨论】：

查看 Tomcat 中的日志文件并尝试找出抛出的异常（如果有）。
当我通过 Eclipse 嵌入式 Tomcat 运行时，我的应用程序运行良好。但是在eclipse之外它没有部署在Tomcat上。 eclipse和Tomcat生成的日志是一样的。
您是否检查了兼容性矩阵。你用的是什么版本的tomcat？
Apache Tomcat/8.5.27
你是通过tomcat服务器的manger gui部署war吗？

标签： spring tomcat spring-boot tomcat8.5

【解决方案1】：

为了能够在您已经做的基础上创建一个可部署的战争文件；

1) 你的 main (Application 类) 应该扩展 SpringBootServletInitializer 并覆盖 configure 方法，如下所示：

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

2) 在您的 pom 文件中，您应该向 tomcat 添加提供的依赖项，以防止嵌入式容器干扰外部容器：

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

添加这些后，它应该可以正常工作。

【讨论】：

添加您提到的上述详细信息后。当我在本地启动 tomcat 时，我至少看到了 Spring boot 横幅，但我仍然无法通过 Tomcat Web 应用程序管理器部署 war 文件。它给了我404错误。请提出建议。
你使用的是什么版本的Tomcat？
Apache Tomcat/8.5.27
我也在上面贴了日志。我无法弄清楚这个问题。有没有您推荐尝试的示例项目？我尝试了一些示例，但效果不佳。
