我试图在 intelliJ 中运行我的 spring Boot 应用程序但出现错误：

我正在使用 Gradle。这是我的 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");

  }

}

这是我的应用程序类：

 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);
  }

}

而且我也尝试了这些注释。

 @ComponentScan
@EnableAutoConfiguration
@Configuration

我是 spring 的新手，我真的不明白这些注释的作用。我尝试遵循其中的一些但无法解决问题。

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

Spring Boot 测试：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 给我一个错误： Unable to start embedded Tomcat 。有人可以帮我吗？

我能够启动并运行您的应用程序。我为让它运行所做的唯一更改是在 build.gradle 文件中注释掉几个依赖项。

在下面的依赖块中，注释掉了 3 行。我注释掉的 spring-boot-start-jpa 行只是因为我没有配置的数据源。

但是，如果您只注释掉 servlet-api 和 jstl 依赖项，您的应用程序应该可以正常启动，这对我来说确实如此。

 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 上。最后我通过评论这个来让它工作：

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

我确实花了很多时间来弄清楚这一点。希望这对遇到类似错误的人有所帮助。
