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 天的新手，我并不真正理解这些注释的作用 . 我尝试了其中的一些，但无法解决问题 .

Spring Boot: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

Spring Boot Testing: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

我尝试使用控制台（gradle build）构建应用程序，构建成功但运行 war 给了我一个错误： Unable to start embedded Tomcat . 有人可以帮帮我吗？

java spring spring-mvc frameworks spring-boot

    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，有3行被注释掉 . 我注释掉的spring-boot-start-jpa行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')
}

    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：

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

    我花了很多时间搞清楚这一点 . 希望这能帮助那些遇到类似错误的人 .

    在我的情况下，我错过了在 pom.xml 中添加这个

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.5.RELEASE</version>
    </parent>

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

    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 .
