springboot与spring比较区别

一、从一道面试题说起

springboot核心能力：

1、内嵌 Servlet 容器，可以直接打成jar包，通过 java -jar xx.jar 运行项目。

2、提供 starter pom 系列，简化maven的依赖加载，减少依赖冲突的发生。

3、

@EnableAutoConfiguration

@Import({AutoConfigurationImportSelector.class})

protected List<String> getCandidateConfigurations(AnnotationMetadata metadata, AnnotationAttributes attributes) {
        List<String> configurations = SpringFactoriesLoader.loadFactoryNames(this.getSpringFactoriesLoaderFactoryClass(), this.getBeanClassLoader());
        Assert.notEmpty(configurations, "No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.");
        return configurations;
    }
