1 package com.goku.demo; 2 3 import org.springframework.boot.SpringApplication; 4 import org.springframework.boot.autoconfigure.SpringBootApplication; 5 import org.springframework.boot.web.servlet.ServletComponentScan; 6 7 /** 8 * Created by nbfujx on 2017/11/20. 9 */ 10 // Spring Boot 应用的标识 11 @SpringBootApplication 12 @ServletComponentScan 13 public class DemoApplication { 14 15 public static void main(String[] args) { 16 // 程序启动入口 17 // 启动嵌入式的 Tomcat 并初始化 Spring 环境及其各 Spring 组件 18 SpringApplication.run(DemoApplication.class,args); 19 } 20 }
4.ExampleController控制器编写

1 package com.goku.demo.controller; 2 3 import org.springframework.web.bind.annotation.PathVariable; 4 import org.springframework.web.bind.annotation.RequestMapping; 5 import org.springframework.web.bind.annotation.RestController; 6 7 /** 8 * Created by nbfujx on 2017-11-20. 9 */ 10 @RestController 11 public class ExampleController { 12 13 @RequestMapping("/") 14 public String helloWorld() 15 { 16 return "helloWorld"; 17 } 18 19 @RequestMapping("/{str}") 20 public String helloWorld(@PathVariable String str) 21 { 22 return "hello"+ str; 23 } 24 }
5.使用MockMvc对Controller进行测试
添加相关单元测试
