2、SpringBoot项目结构说明
3、入门案例关键配置说明 前面我们学习了SpringBoot快速入门案例本节我们通过POM文件和项目结构分析两部分内容了解下关于SpringBoot的一些配置说明以便全面了解SpringBoot项目结构组成及依赖技术栈。 1、pom.xml文件配置说明
?xml version1.0 encodingUTF-8?

2) gitignore文件 使用版本控制工具git的时候设置一些忽略提交的内容。这样可以避免很多无效文件提交到远程仓库。如class文件、.idea文件内容等。
3static|templates文件夹 涉及到页面或模板技术都会存放该目录下比如html页面、JS脚本、CSS样式以及Thymeleaf等。
4application.properties(默认生成) | application.yml手动添加 SpringBoot的配置文件很多集成的配置都可以在该文件中进行配置。例如服务端口号、应用名称、数据库(Redis、ES、MySQL)连接信息、MyBatis配置、Rabbit MQ等。
5SpringbootApplication.java 该类是SpringBoot程序执行的入口执行该程序中的main方法SpringBoot就启动了。 3、入门案例关键配置说明
1Spring Boot的父级依赖spring-boot-starter-parent配置之后当前的项目就是Spring Boot项目。
parentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.7.7/versionrelativePath/ !-- lookup parent from repository --
/parent
2spring-boot-starter-parent是一个Springboot的父级依赖开发SpringBoot程序都需要继承该父级项目它用来提供相关的Maven默认依赖使用它之后常用的jar包依赖可以省去version配置。
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId!--省略版本号--
/dependency
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-test/artifactIdscopetest/scope!--省略版本号--
/dependency
3Spring Boot提供了哪些默认jar包的依赖可查看该父级依赖的pom文件。大约有200多个依赖包从中我们可以了解SpringBoot融合了哪些技术栈便于我们全面了解SpringBoot这门技术。

4如果在项目中不想使用某个默认依赖版本可通过修改pom.xml文件的单独依赖配置覆盖即可比如需要用Spring版本3.x 覆盖2.x。

5SpringBootApplication注解属于Spring Boot项目的最核心注解主要作用开启Spring自动配置。如果在启动类上去掉该注解那么就不会启动SpringBoot程序。
package com.xintu.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;RestController
SpringBootApplication
public class SpringbootApplication {//...
}6main方法是一个标准的Java程序的main方法主要作用是作为项目启动运行的入口。
package com.xintu.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;RestController
SpringBootApplication
public class SpringbootApplication {public static void main(String[] args) {SpringApplication.run(SpringbootApplication.class, args);}//...
}7RestController 依然是我们之前的Spring MVC这个注解类内部包含了Controller 和 ResponseBody注解简化了原来Spring的配置方式。
package com.xintu.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;RestController
SpringBootApplication
public class SpringbootApplication {public static void main(String[] args) {SpringApplication.run(SpringbootApplication.class, args);}GetMapping(/hello)public String hello(RequestParam(value name, defaultValue World) String name) {return String.format(欢迎 %s 来到a href\http://www.35xintu.com\35新途/a, name);}}我们看下RestController源码
package org.springframework.web.bind.annotation;import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.springframework.core.annotation.AliasFor;
import org.springframework.stereotype.Controller;Target({ElementType.TYPE})
Retention(RetentionPolicy.RUNTIME)
Documented
Controller //原Spring配置
ResponseBody //原Spring配置
public interface RestController {AliasFor(annotation Controller.class)String value() default ;
}其内部引入了Controller 和 ResponseBody这两个注解。
下一篇将详细介绍关于SpringBoot核心配置便于我们进一步深入了解Springboot可管理的配置化能力。
