在程序入口加入:
@SpringBootApplication public class SpringbootFirstApplication { public static void main(String[] args) { SpringApplication.run(SpringbootFirstApplication.class, args); } @Bean public CommandLineRunner commandLineRunner(ApplicationContext ctx) { return args -> { System.out.println("Let‘s inspect the beans provided by Spring Boot:"); String[] beanNames = ctx.getBeanDefinitionNames(); Arrays.sort(beanNames); for (String beanName : beanNames) { System.out.println(beanName); } }; } }
程序输出:
Let’s inspect the beans provided by Spring Boot: basicErrorController beanNameHandlerMapping beanNameViewResolver characterEncodingFilter commandLineRunner conventionErrorViewResolver defaultServletHandlerMapping defaultViewResolver dispatcherServlet dispatcherServletRegistration duplicateServerPropertiesDetector embeddedServletContainerCustomizerBeanPostProcessor error errorAttributes errorPageCustomizer errorPageRegistrarBeanPostProcessor …. ….
在程序启动的时候,springboot自动诸如注入了40-50个bean.
通过@RunWith() @SpringBootTest开启注解:
@RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class HelloControllerIT { @LocalServerPort private int port; private URL base; @Autowired private TestRestTemplate template; @Before public void setUp() throws Exception { this.base = new URL("http://localhost:" + port + "/"); } @Test public void getHello() throws Exception { ResponseEntity<String> response = template.getForEntity(base.toString(), String.class); assertThat(response.getBody(), equalTo("Greetings from Spring Boot!")); } }
运行它会先开启sprigboot工程,然后再测试,测试通过
