@SpringBootApplication:申明让spring boot自动给程序进行必要的配置,这个配置等同于:@Configuration ,@EnableAutoConfiguration 和 @ComponentScan 三个配置。 package com.example.myproject; import org.springframework.boot.SpringApplication;
@Componentpublic@interfaceService{@AliasFor(annotation=Component.class)Stringvalue()default"";}// @Repository@Target({ElementType.TYPE})@Retention(RetentionPolicy.RUNTIME)@Documented @Componentpublic@interfaceRepository{@AliasFor(annotation=Component.class)Stringvalue()default"";}// @Component@Target(ElementTyp...
ConfigurationAnnotationConfig类的作用就是充当程序启动的配置类,会在ConfigurationAnnotationConfig类上标注@Configuration注解,说明ConfigurationAnnotationConfig类是Spring启动时的配置类。 源码详见:spring-annotation-chapter-01工程下的io.binghe.spring.annotation.chapter01.configuration.config.ConfigurationAnnotationConfig,如下...
1. Spring @Configuration annotation usage Use@Configurationannotation on top of any class to declare that this class provides one or more@Beanmethods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. @Configuration publicclassA...
Learn Springcourse, focused on the fundamentals of Spring 5 and Spring Boot 2: 1. Overview In this article, we'll explore the@WebAppConfigurationannotation in Spring, why we need it in our integration tests and also how can we configure it so that these tests actually bootstrap aWebApplicati...
只有开启了context:annotation-config/,才能够启用ConfigurationClassPostProcessor和其他相关注解的后置处理器来处理@Configuration标注的类。 那么也就是说,如果不添加的话,可能就会对配置类的解析造成响应的问题。 1.3、添加扫描包逻辑 @Configurationis meta-annotated with@Component, therefore@Configurationclasses are can...
有一个myBean()的方法,返回一个MyBean()的实例,并用@Bean 进行注释,表明这个方法是需要被Spring进行管理的bean。@Bean 如果不指定名称的话,默认使用myBean名称,也就是小写的名称。 通过注解启动 通过启动一个AnnotationConfigApplicationCont...
Step 3) Next step is to configure Spring MVC. I do that in following class.@EnableWebMvc annotation used together with @Configuration enables default Spring MVC configuration, equivalent to . With @ComponentScan annotation we make sure our @Controller will be added to the application context. Th...
若Spring MVC存在,则创建AnnotationConfigServletWebServerApplicationContext;若Spring MVC不存在,而Spring WebFlux存在,则创建AnnotationConfigReactiveWebServerApplicationContext ;否则,创建AnnotationConfigApplicationContext。也就是优先使用Spring MVC。我们可以通过调用setWebApplicationType(WebApplicationType)来覆盖默认的类型。
