技术标签:
【中文标题】无法启动 Spring Boot 应用程序【英文标题】：Unable to start spring boot application 【发布时间】：2015-05-10 04:37:43 【问题描述】：我无法使用 @SpringBootApplication 启动我的应用程序。
@SpringBootApplication
public class AppInitializer extends SpringBootServletInitializer
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
return application.sources(AppInitializer.class);
public static void main(String[] args)
ConfigurableApplicationContext ctx = new AppInitializer().configure(new SpringApplicationBuilder(AppInitializer.class)).run(args);
System.out.println("count="+ctx.getBeanDefinitionCount());
pom.xml 使用：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jersey</artifactId>
<exclusions>
<exclusion>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet-core</artifactId>
</exclusion>
</exclusions>
</dependency>
当我运行应用程序时，出现以下错误：

【问题讨论】：
这是你的整个 pom.xml 吗？请发布所有依赖项。 servlet api jar 中似乎存在版本冲突。 添加了依赖树供您参考。有 jersey-container-servlet-core 和 jersey-container-servlet jars。 【参考方案1】：发现问题：依赖jersey-container-servlet-core只适用于低于Servlet 3.0规范的servlet容器。由于您使用实现 Servlet 3.0 的 Tomcat 7，因此您必须使用 jersey-container-servlet。在此处查看泽西岛文档：https://jersey.java.net/documentation/latest/modules-and-dependencies.html#servlet-app-general
如果您将应用程序作为独立应用程序运行（即不将其部署到 Tomcat 中），则必须确保依赖项 spring-boot-starter-tomcat 在“编译”范围内。目前依赖的范围是“provided”，这意味着在运行应用程序时，依赖不在类路径上。
如果你想在 Tomcat 和独立应用程序中运行你的应用程序，你必须使用 Maven 配置文件并构建两个 WAR，一个带有 spring-boot-starter-tomcat，一个带有 spring-boot-starter- tomcat 作为编译器。
【讨论】：
我在 pom 中为 jersey-container-servlet-core 添加了排除项。它现在抛出不同的错误： java.util.concurrent.ExecutionException: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;在 java.util.concurrent.FutureTask.report(FutureTask.java:122) 主要原因还是一样的，还是API版本冲突。你使用 IDE 吗？如果是这样，您能否搜索类 ServletContext，并查看该类出现了多少次，以及在哪些 JAR 中？ Tomcat jar 中应该只出现一次。 我正在使用 GGTS IDE，它没有显示任何 ServletContext :-( . 好的，那我没有更多的想法了 :( 我尝试了不同的 IDE 来检查是否出现。 ServletContext 仅来自 tomcat-embed-core-7.0.57.jar。以上是关于无法启动 Spring Boot 应用程序的主要内容，如果未能解决你的问题，请参考以下文章
