Question

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class App {
    public static void main(String[] args) {
        SpringApplication.run(SampleController.class, args);
    }

@Controller
@EnableAutoConfiguration
public class SampleController {
    @RequestMapping("/help")

在阅读了大量页面和问答后，我在POM中添加了以下内容：

http://maven.apache.org/xsd/maven-4.0.0.xsd“>4.0.0

<groupId>com.niewlabs</groupId>
<artifactId>highlighter</artifactId>
<version>1.0-SNAPSHOT</version>

<packaging>war</packaging>

<properties>
    <java.version>1.8</java.version>
</properties>    
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.1.9.RELEASE</version>
</parent>    
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
</dependencies>

我运行了“MVN包”，得到了WAR文件（大小250MB)，我把它放进了“webapps”文件夹。

本指南详细解释了如何在Tomcat上部署Spring Boot应用程序:
http://docs.Spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

基本上我需要添加以下类：

public class WebInitializer extends SpringBootServletInitializer {   
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }    
}

此外，我还为POM添加了以下属性：

<properties>        
    <start-class>mypackage.App</start-class>
</properties>
