自定义SpringApplication

SpringApplication

SpringApplication 是Spring Boot 驱动Spring 应用上下文的引导类

@SpringBootConfiguration
@EnableAutoConfiguration
@ omponentScan(
    excludeFilters = {@Filter(
    type = FilterType.CUSTOM,
    classes = {TypeExcludeFilter.class}
), @Filter(
    type = FilterType.CUSTOM,
    classes = {AutoConfigurationExcludeFilter.class}
)}
)
public @interface SpringBootApplication {

@componentScan:它是在Spring Framework 3.1 引入的

@EnableAutoConfiguration ：激活自动装配 @Enalbe -> @Enable 开头的

• @EnableWebMvc
• @EnableTransactionManagement
• ``

@SpringBootConfiguration :等价于 @Configuration ->Configuation Class 注解

@Component 的“派生性”

Spring注解编程模型链接

• @Component
  • @Service
    • 
  • @Repository
    • 
  • @Controller
    • 
  • @Configuration
    • 

Spring 模式注解： Stereotype Annotations

Spring 注解驱动的示例

注解驱动上下文 AnnotationConfigApplicationContext ,Spring Framework 3.0开始引入的

@SpringBootApplication 标注当前一些功能
等价于

SpringApplication Spring Boot 应用的引导

SpringApplicationBuilder

 new SpringApplicationBuilder(MicroservicesProjectApplication.class)
                //单元测试是PORT=RANDOM
                .properties("server.port=0") //随机向os要可用端口
                .run(args);

调整示例为非web程序
