Spring启动 – 由于缺少EmbeddedServletContainerFactory bean，无法启动EmbeddedWebApplicationContext

春季启动

我试图在intelliJ中运行我的spring Boot应用程序但是遇到错误：

我使用Gradle.This是我的build.gradle文件：

 buildscript { ext { springBootVersion = '1.3.1.RELEASE' } repositories { mavenCentral() } dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") } } apply plugin: 'java' apply plugin: 'eclipse' apply plugin: 'idea' apply plugin: 'spring-boot' apply plugin: 'war' war { baseName = 'Example-Application' version = '0.0.1-SNAPSHOT' } sourceCompatibility = 1.8 targetCompatibility = 1.8 repositories { mavenCentral() } dependencies { compile('org.springframework.boot:spring-boot-starter-data-jpa') compile('org.springframework.boot:spring-boot-starter-security') compile('org.springframework.boot:spring-boot-starter-web') compile('org.apache.tomcat.embed:tomcat-embed-jasper:8.0.30') compile('javax.servlet:servlet-api:2.5') compile('javax.servlet:jstl:1.2') runtime('mysql:mysql-connector-java') providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat' testCompile('org.springframework.boot:spring-boot-starter-test') } eclipse { classpath { containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER') containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8' } } task wrapper(type: Wrapper) { gradleVersion = '2.9' } 

这是配置类：

 package com.example.he.config; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; @Configuration public class MvcConfig extends WebMvcConfigurerAdapter { @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/city").setViewName("city"); registry.addViewController("/").setViewName("city"); registry.addViewController("/userAdd").setViewName("user"); registry.addViewController("/created").setViewName("created"); registry.addViewController("/createblog").setViewName("blog"); registry.addViewController("/login").setViewName("login"); registry.addViewController("/home").setViewName("home"); } } 

这是我的Application类：

 package com.example.he; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.context.web.SpringBootServletInitializer; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.scheduling.annotation.EnableScheduling; @SpringBootApplication public class ExampleApplication extends SpringBootServletInitializer{ public static void main(String[] args) throws Exception { SpringApplication.run(ExampleApplication.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(ExampleApplication.class); } } 

而且我也试过这些注释。

 @ComponentScan @EnableAutoConfiguration @Configuration 

我是spring的新手，我并不真正理解这些注释的作用。我尝试了其中一些，但无法解决问题。

Spring Boot：由于缺少EmbeddedServletContainerFactory bean，无法启动EmbeddedWebApplicationContext

Spring Boot Testing：由于缺少EmbeddedServletContainerFactory bean，无法启动EmbeddedWebApplicationContext

我尝试使用控制台（gradle build）构建应用程序，构建成功但运行war会给我一个错误： 无法启动嵌入式Tomcat 。 有人可以帮帮我吗？

Answer 1

我能够启动并运行您的应用程序。 我为使其运行而做的唯一更改是在build.gradle文件中注释掉几个依赖项。

在下面的依赖项块中，注释掉了3行。 我注释掉的spring-boot-start-jpa只是因为我没有配置的dataSource。

但是，如果您只注释掉servlet-api和jstl依赖项，那么您的应用应该没有问题，它确实适用于我。

 dependencies { //compile('org.springframework.boot:spring-boot-starter-data-jpa') compile('org.springframework.boot:spring-boot-starter-security') compile('org.springframework.boot:spring-boot-starter-web') compile('org.apache.tomcat.embed:tomcat-embed-jasper:8.0.30') //compile('javax.servlet:servlet-api:2.5') //compile('javax.servlet:jstl:1.2') runtime('mysql:mysql-connector-java') providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat' testCompile('org.springframework.boot:spring-boot-starter-test') } 

Answer 2

我也有这个错误，它只发生在Intellij。 最后我通过评论这个来得到它：

  org.springframework.boot spring-boot-starter-tomcat provided  

我花了很多时间搞清楚这一点。 希望这可以帮助那些遇到类似错误的人。

Answer 3

在我的情况下，我错过了在pom.xml中添加它

  org.springframework.boot spring-boot-starter-parent 1.2.5.RELEASE  

Answer 4

在主启动应用程序类上添加注释对我有用。 @EnableAutoConfiguration公共类ExampleApplication {…..

Answer 5

清理C:\Users\Lenovo\.m2\repository ，然后重新导入所有maven依赖项，对我有用。 我还删除了我的pom.xml中的所有重写依赖项。
