### 1. 构建一个普通的Maven项目 ###

### 2. 按如下修改pom.xml ###

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
    
      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath/>
      </parent>
      <groupId>com.zjw</groupId>
      <artifactId>job</artifactId>
      <version>1.0-SNAPSHOT</version>
      <packaging>war</packaging>
      <dependencies>
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
          
          <exclusions>
            <exclusion>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
          </exclusions>
        </dependency>
        <dependency>
          <groupId>javax.servlet</groupId>
          <artifactId>javax.servlet-api</artifactId>
          <version>3.1.0</version>
          <scope>provided</scope>
        </dependency>
      </dependencies>
    </project>

### 3. 创建启动类 ###

package com.zjw;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /** * @author zjw <cn.zjwblog@gmail.com> 2020/6/28 */
    @SpringBootApplication
    public class Application { 
        public static void main(String[] args) { 
            SpringApplication.run(Application.class, args);
        }
    }

### 4. 创建配置类 ###

package com.zjw;
    
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    
    /** * @author zjw <cn.zjwblog@gmail.com> 2020/6/28 */
    public class SpringBootStartApplication extends SpringBootServletInitializer { 
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { 
            return builder.sources(Application.class);
        }
    }

### 5. 创建一个测试的Controller类 ###

package com.zjw.controller;
    
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    
    /** * @author zjw <cn.zjwblog@gmail.com> 2020/6/28 */
    @RestController
    public class MyController { 
    
      @GetMapping("/hello")
      public String hello(@RequestParam(name = "timeout", required = false) Long timeout) { 
        try { 
          Thread.sleep(timeout);
        } catch (InterruptedException e) { 
          e.printStackTrace();
        }
        return "sleep " + timeout + " ms!";
      }
    }

#### 6. 打包 ####

mvn clean package

### 7. 部署 ###

拷贝target下的war包到tomcat webapps目录下
