# 工程搭建 #

本文工程搭建使用的工具：

> JDK1.8  
> Maven  
> idea

打开idea，新建一个project，然后右键工程，新建一个module,选择Spring Initializr  
![这里写图片描述][SouthEast]

然后next，填写group、artifact ，然后next,

![这里写图片描述][SouthEast 1]

选择web,next完成工程创建。  
工程目录如下：

- src     -main         -java             -package                 -SpringbootApplication         -resouces             - statics             - templates             - application.yml     -test - pom

pom文件如下：

<?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>
    
        <groupId>com.springcloud</groupId>
        <artifactId>springboot</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <packaging>jar</packaging>
    
        <name>springboot</name>
        <description>Demo project for Spring Boot</description>
    
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.5.9.RELEASE</version>
            <relativePath/> 
        </parent>
    
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
            <java.version>1.8</java.version>
        </properties>
    
        <dependencies>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
    
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    
    </project>

修改程序入口类如下：

/** * @author wang_ */
    @SpringBootApplication
    public class SpringbootApplication extends SpringBootServletInitializer { 
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(SpringbootApplication.class);
        }
    
        public static void main(String[] args) {
            SpringApplication.run(SpringbootApplication.class, args);
        }
    }

修改配置文件如下：

# Server settings (ServerProperties)
    #端口
    server.port=8082
    server.address=127.0.0.1
    #server.sessionTimeout=30
    #访问路径名称
    server.contextPath=/boot

新建一个test.controller包，新建一个web类：

/** * @Package:com.springboot.test.controller * @ClassName:test * @Description:测试web * @Author Shuyu.Wang * @Date 2017-12-07 10:05 **/
    @RestController
    public class TestController { 
        @RequestMapping(value = "/hello",method = RequestMethod.GET)
        public String hello(){
            return  "hello Spring boot";
        }
    }

运行程序，看到控制台：

说明程序启动成功了。

然后浏览器访问：[http://127.0.0.1:8082/boot/hello][http_127.0.0.1_8082_boot_hello]  
返回：

> hello Spring boot  
> 第一个spring boot工程完成
