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

然后next，填写group、artifact ，然后next,

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"

            </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";
    }
}
