Spring Boot是由Pivotal团队提供的全新框架,其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置,从而使开发人员不再需要定义样板化的配置。通过这种方式,Spring Boot致力于在蓬勃发展的快速应用开发领域(rapid application development)成为领导者。
就是@Controller+@ResponseBody组合,支持RESTful访问方式,返回结果都是json字符串
就是@SpringBootConfiguration+@EnableAutoConfiguration+
@ComponentScan等组合在一下,非常简单,使用也方便
Spring Boot版本1.4才出现的,具有Spring Boot支持的引导程序(例如,加载应用程序、属性,为我们提供Spring Boot的所有精华部分)
关键是自动导入测试需要的类。。。

@Test
public void getHello() throws Exception {
mockMvc.perform(MockMvcRequestBuilders.get("/hello1").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk())

运行Application的main方法,打开浏览器:
http://localhost:8080/hello1
输出Hello World
http://localhost:8080/hello2
输出[“A”,”B”,”C”]
运行HelloWorldControllerTest
