我如何将Spring Boot WAR部署到Tomcat？

javatomcatspring-bootwar
3

在发布之前，我花了不少时间处理这个问题……

我有一个正常运行的 Spring Boot 应用程序，可以作为 JAR 运行，但当我尝试将其转换为 WAR 时无法部署。

我尝试查找相关规则，以确定是嵌入式 Tomcat 还是外部 Tomcat。

WAR 文件似乎没问题，带有 WEB-INF/lib 和 WEB-INF/lib-provided 目录，没有明显错放的 JAR 包。

我的 Application 类扩展了 SpringBootServletInitializer。在调试时，此类将应用程序上下文类设置为 AnnotationConfigEmbeddedWebApplicationContext.class... 这样做是否正确？

在尝试将其部署为 WAR 文件时，是否应该看到加载 Embedded 类？

我使用的是：

1）Spring Framework 4.1.2.RELEASE 2）Spring Boot 1.1.9.RELEASE 3）Spring Security 3.2.5.RELEASE 4）Tomcat 7.0.57

该应用程序同时使用 WebMvc 和 WebSockets……

谢谢

我的父 POM 中包含：

这是将其作为WAR包在Tomcat 7.0.57中部署，并使用-Ddebug参数。

很抱歉会有这么多日志记录；-(

确保您没有web.xml，如果有，请删除它或确保其版本为3.0而不是更低版本。发布一些配置和您的pom文件。在我看来，您正在覆盖默认的Spring Boot依赖项，而不是使用推荐的starters。如果我没记错的话，Spring boot 1.1.x使用的是Spring 4.0。 - M. Deinum
starter-web依赖项不应标记为提供。只有starter-tomcat需要它。 - Andy Wilkinson
我已经从starter-web依赖项中删除了“provided”范围。结果是相同的。 - CobraFlow

好的，我已经找到问题所在...配置文件！

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application
            .showBanner(true)
            .parent(Global.class)
            .child(applicationClass)
            .profiles("container")
            ;
}

应该是...

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application
            .showBanner(true)
            .parent(Global.class)
            .sources(applicationClass)
            .profiles("container")
            ;
}

我使用了child()而不是sources()...

你能将父项目设置为spring-boot-starter-parent吗？
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.1.9.RELEASE</version>
</parent>

此外，您应该将spring-boot-starter-tomcat设置为提供的。

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

如果您链接整个POM或有效的POM，可能会有所帮助。
我无法将父Pom设置为引导父Pom，因为我已经使用了内部层次结构，并且该构件的作用域已设置为如上所述的“提供”。我的WAR文件看起来是正确的。关于引导选择嵌入式还是外部的规则是什么？ - CobraFlow
主要的决策点基于是否存在ServletContext。如果不存在，Boot将启动一个嵌入式容器。 - Andy Wilkinson
我已经更新了问题并附上了日志输出。奇怪的是，它认为应该启动嵌入式Tomcat，而实际上是由Tomcat加载的WAR文件。在这种情况下，我会认为不应该看到任何类名中带有“Embed”一词的类... - CobraFlow
调试代码时，我发现没有servletContext，因此创建了一个嵌入式Servlet容器。Catalina servletContext可用于SpringBootServletInitializer.onStartup()，但似乎要么丢失，要么未传递... - CobraFlow
