了解Spring

Spring-boot的优点：

1.Spring框架的“约定优先于配置（COC）”理念以及最佳实践。 2.针对日常企业应用研发各种场景的Spring-boot-starter自动配置依赖模块，且“开箱即用”（约定spring-boot-starter- 作为命名前缀，都位于org.springframenwork.boot包或者命名空间下）。

Spring-boot-starter包括的依赖项目以下

<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-autoconfigure</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </dependency> <dependency> <groupId>javax.annotation</groupId> <artifactId>javax.annotation-api</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </dependency> <dependency> <groupId>org.yaml</groupId> <artifactId>snakeyaml</artifactId> <scope>runtime</scope> </dependency> </dependencies>
