上次试用Spring Boot还是两年前: 中文代码示例之Spring Boot 1.3.3演示. 打算用在一个讨论组内小项目上, 于是从官网Building an Application with Spring Boot入门开始.
源码库: program-in-chinese/spring_boot_hello_zh
汉化后的源码如下:
问好控制器:
@RestController
public class 问好控制器 {
@RequestMapping("/")
public String 索引() {
return "Spring Boot问好!";
}
}主入口:
@SpringBootApplication
public class 应用 {
public static void main(String[] 参数) {
SpringApplication.run(应用.class, 参数);
}
@Bean
public CommandLineRunner 命令行运行器(ApplicationContext 上下文) {
return 参数 -> {
System.out.println("检查一下Spring Boot提供的beans:");
String[] bean名 = 上下文.getBeanDefinitionNames();
Arrays.sort(bean名);
for (String 某bean名 : bean名) {
System.out.println(某bean名);
}
};
}
}控制器单元测试:
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class 问好控制器Test {
@Autowired
private MockMvc mvc;
@Test
public void 取问好() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().string(equalTo("Spring Boot问好!")));
}
}集成测试:
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class 问好控制器集成测试 {
@LocalServerPort
private int 端口;
private URL 基础网址;
@Autowired
private TestRestTemplate 模板;
@Before
public void 初始化() throws Exception {
this.基础网址 = new URL("http://localhost:" + 端口 + "/");
}
@Test
public void 取问好() throws Exception {
ResponseEntity<String> 响应 = 模板.getForEntity(基础网址.toString(),
String.class);
assertThat(响应.getBody(), equalTo("Spring Boot问好!"));
}
}本地启动应用:
$ mvn package && java -jar target/spring-boot-hello-0.1.0.jar访问本地端口响应如期:
$ curl localhost:8080
