SpringBoot(Ⅰ)——HelloWorld和基本打包部署+Pom依赖概述+@SpringBootApplication注解+自动装配原理+约定大于配置

news2024/11/15 8:05:38

前言

如果SSM学的比较好,那么SpringBoot说白了就两件事:约定大于配置和自动装配

SpringBoot不会提供任何的功能拓展,完全依赖我们手动添加

所以SpringBoot的本质是一个依赖脚手架,可以快速集成配置各种依赖

1.1 SpringBoot相关依赖

创建maven项目,引入spring‐boot‐starter‐parent和spring‐boot‐starter‐web两个依赖

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring‐boot‐starter‐parent</artifactId>
<version>1.5.9.RELEASE</version>
</parent>
<dependencies>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring‐boot‐starter‐web</artifactId>
</dependency>
</dependencies>

这两个是最核心的依赖,其他的都是锦上添花

1.2 创建SpringBoor启动类:项目名+Application.java

/**
* @SpringBootApplication 来标注一个主程序类,说明这是一个Spring Boot应用
* SpringBoot项目从此类的main方法启动
*/
@SpringBootApplication
public class HelloWorldMainApplication {
    public static void main(String[] args) {
    // Spring应用启动起来
    SpringApplication.run(HelloWorldMainApplication.class,args);
    }
}

1.3 编写Controller并访问

@Controller
public class HelloController {
   @ResponseBody
   @RequestMapping("/hello")
   public String hello(){
      return "Hello World!";
   }
}

我这里是改了端口,默认是8080

1.4 部署SpringBoot项目

    <!--这个插件,可以将应用打包成一个可执行的jar包-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

repackage是此插件的5个goal之一,而且是默认的goal。

在mvn package之后,再次打包可执行的jar/war,同时保留mvn package生成的jar/war为.origin;重新打包存在的jar或者war包从而使他们可以在命令行使用jar -jar来执行,使用layout=NONE也可以简单的打包有嵌套依赖的jar(没有主类,所以无法执行);它可以替代常规的构件或者连接到构建生命周期并有独立的分级。

现在我们来试一试

运行package命令

找到target目录下,查看package成功后的jar包

使用windows的命令行启动此jar包(java -jar命令)

注意:启动之前先把IDEA的项目关闭,否则会报错端口已被占用

在这里插入图片描述

java -jar -Xms128m -Xmx256m springBoot01-0.0.1-SNAPSHOT.jar

最小内存占用128MB,最大内存占用256MB

访问9090端口

2.1 spring-boot-starter-parent的pom文件分析

有了这个parent标签之后,<dependencies>中的很多<dependency>都不需要再指定版本,整个pom文件的配置都清爽了很多。

那么,都是哪些依赖不再需要我们手动指定版本了呢?

我们可以看到,spring-boot-starter-parent其实也是依靠其他pom文件的依赖实现自己的依赖功能的

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.6.13</version>
  </parent>

spring-boot-dependencies来真正管理Spring Boot应用里面的所有依赖版本;

spring-boot-dependencies是Spring Boot的版本仲裁中心;

其中依赖继承的数量很多,我们挑选其中几个常用的进行说明

activemq:消息队列的一种,目前有很多更好的上位替代
commons-codec:加解密/签名验签的基础依赖
hibernate:hibernate框架依赖
jackson:json处理依赖
log4j2:日志管理
thymeleaf:模板引擎,用于视图层
org.apache.tomcat:springboot内置的tomcat,版本9.0.68
org.junit:测试的依赖
mysql:mysql数据库连接驱动,版本8.0.31
okhttp3:http请求的基础依赖包
oracle-database:oracle数据库的驱动

2.2 spring-boot-starter-web是什么?

是spring-boot场景启动器;

帮我们导入了web模块正常运行所依赖的组件;(一些默认的配置)

SpringBoot约定大于配置思想的体现

类似的starter有很多,比如druid的SpringBootStarter,MyBatis的starter

Spring Boot将所有的功能场景都抽取出来,做成一个个的starters(启动器),

只需要在项目里面引入这些starter
相关场景的所有依赖都会导入进来。要用什么功能就导入什么场景的启动器

我们在浏览器访问localhost:9090/hello本质上是一个web请求,所以当然需要我们导入web相关的包,

spring-boot-starter-web已经帮我们配置好了默认的依赖

xxx-starter包含了完成某一个功能模块的所有jar包,无需xml,开箱即用

其中最重要的是spring-boot-starter依赖,我们可以在各种starter中看到它

3.1 @SpringBootApplication注解

@SpringBootApplication标注在某个类上说明这个类是SpringBoot的主配置类,SpringBoot
就通过运行这个类的main方法来启动SpringBoot应用;

    @AliasFor(

    )
    boolean proxyBeanMethods() default true;
}

@Target

@Target({ElementType.TYPE}):表示只能标注在类上

@Retention

@Retention(RetentionPolicy.RUNTIME):表示此注解可以一直保留到JVM内存中
@Documented:运行javadoc命令时会带上@SpringBootApplication注解,不标注则不会带上

@Inherited`

@Inherited:这个注解只能标注在注解上,表示如果一个类用上了@Inherited修饰的注解,那么其子类也会继承这个注解(接口和实现类的父子关系不生效不行)

@SpringBootConfiguration

@SpringBootConfiguration:加载SpringBoot的配置。继承自@Configuration,二者功能也一致,标注当前类是配置类,并会将当前类内声明的一个或多个以@Bean注解标记的方法的实例纳入到spring容器中,并且实例名就是方法名。

@SpringBootConfiguration是springboot的注解,而@Configuration是spring的注解

纳入spring容器的方式是通过动态代理,proxyBeanMethods即是此含义(CGLIB)

更详细的解释:Spring框架中的@Configuration参数proxyBeanMethods

@EnableAutoConfiguration

@EnableAutoConfiguration:SpringBoot有两大核心:依赖大于配置&&自动装配,@EnableAutoConfiguration即为完成自动装配的核心注解(开启自动配置功能)在这里插入图片描述)

当spring boot扫描到@EnableAutoConfiguration注解时则会将spring-boot-autoconfigure.jar/META-INF/spring.factories文件中org.springframework.boot.autoconfigure.EnableAutoConfiguration对应的value里的所有xxxConfiguration类加载到IOC容器中。而xxxAutoConfiguration类一般都会有@ConditionalOnxxx注解,通过这些条件注解来判断是否真正的创建xxxConfiguration对象。spring boot的各种spring-boot-starter-xxx.jar也正是居于此注解来达到自动装配的目的。

在这里插入图片描述

这些标签都是可以ctrl点进去的,每一个都对应一个xxxAutoConfiguration配置类,这些类在这些包中
在这里插入图片描述

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@AutoConfigurationPackage
@Import({AutoConfigurationImportSelector.class})
public @interface EnableAutoConfiguration {
    String ENABLED_OVERRIDE_PROPERTY = "spring.boot.enableautoconfiguration";

    Class<?>[] exclude() default {};

    String[] excludeName() default {};
}
@AutoConfigurationPackage

@AutoConfigurationPackage:自动配置包,导入的组件由AutoConfigurationPackages.Registrar.class决定

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Import({AutoConfigurationPackages.Registrar.class})
public @interface AutoConfigurationPackage {
    String[] basePackages() default {};

    Class<?>[] basePackageClasses() default {};
}

AutoConfigurationPackages是一个抽象类,Registrar是其静态内部类。

AutoConfigurationPackage注解的作用是将添加该注解的类所在的package 作为 自动配置package 进行管理。

将启动类所在的包+子包都注册到自动装配包中
在这里插入图片描述

        public void registerBeanDefinitions(AnnotationMetadata metadata, BeanDefinitionRegistry registry) {
            AutoConfigurationPackages.register(registry, (String[])(new PackageImports(metadata)).getPackageNames().toArray(new String[0]));
        }

通过元数据AnnotationMetadata获取被 @Import 注解的类的注解信息,即注解元数据,进而获取包名,将包名的string数组注册到自动导入包中

这个注解不是很重要,只是定义了一些自动装配的包规则,AutoConfigurationImportSelector才是完成自动装配的重点

AutoConfigurationImportSelector

@Import,给容器中导入一个组件;
将所有需要导入的组件以全类名的方式返回;这些组件就会被添加到容器中;会给容器中导入非常多的自动配置类(xxxAutoConfiguration);就是给容器中导入这个场景需要的所有组件,并配置好这些组件;

将spring-boot-autoconfigure.jar/META-INF/spring.factories文件中org.springframework.boot.autoconfigure.EnableAutoConfiguration对应的value里的所有xxxConfiguration类加载到IOC容器中。而xxxAutoConfiguration类一般都会有@ConditionalOnxxx注解,通过这些条件注解来判断是否真正的创建xxxConfiguration对象。

自动装配原理

自动装配主要是装配两部分的bean组件:本项目内的+依赖jar包内的

依赖jar包又可以分为spring-boot-autoconfigure包+其他

@AutoConfigurationPackage注解将添加该注解的类所在的package 作为自动配置package 进行管理,保存自动配置类的全限定包名以供之后的使用,比如给JPA entity扫描器用来扫描开发人员通过注解@Entity定义的entity类

SpringBoot启动类自动标注了该注解,所以当SpringBoot应用启动时默认会将启动类所在的package作为自动配置的package,提供给后续扫描bean组件的注解:@Controller,@Mapper,@Service等使用

所以@AutoConfigurationPackage负责自动装配本项目内的bean组件,@Import(AutoConfigurationImportSelector.class)负责自动装配pom依赖项目的bean组件

  1. SpringBoot启动的时候加载主配置类,开启了自动配置功能 @EnableAutoConfiguration
  2. @EnableAutoConfiguration注解利用EnableAutoConfigurationImportSelector给容器中导入一些组件。查看selectImports()方法的内容;
// 获取候选的配置
List configurations = getCandidateConfigurations(annotationMetadata, attributes);

SpringFactoriesLoader.loadFactoryNames()
扫描所有jar包类路径下 META‐INF/spring.factories
把扫描到的这些文件的内容包装成properties对象

  1. 从properties中获取到EnableAutoConfiguration.class类(类名)对应的值,然后把他们添加在容器中

  2. 对每一个自动配置类进行自动配置功能

根据当前不同的条件判断,决定这个配置类是否生效;

一旦这个配置类生效,这个配置类就会给容器中添加各种组件

这些组件的属性是从对应的properties类中获取的,这些类里面的每一个属性又是和配置文件绑定的;

约定大于配置

如果有些值你没有配置的话,那程序会取一个默认值,换句话说,能取默认值的配置,就不需要配置了,这个默认值就是约定。

约定可以减少很多配置

约定优于配置(convention over configuration),也称作按约定编程,是一种软件设计范式,旨在减少软件开发人员需做决定的数量,获得简单的好处,而又不失灵活性。

在SpringBoot中,约定大于配置可以从以下几方面来理解:

  1. SpringBoot会加载大量的自动配置类,这些配置类会根据@ConditionalXXX注解默认加载到bean容器中(自动装配+默认配置)

想要修改,可以从resources下的application.yaml中修改配置

在spring boot中提供了一套默认配置,不需要手动去写xml配置文件,不写xml项目也能跑起来。

只有默认配置不能满足我们的需求时,才会去修改配置(自定义yaml文件)

  1. maven的默认目录结构也体现了约定大于配置的思想

     /src/main/java目录用来存放java源文件
     src/main/resources目录用来存放资源文件,如application.yml文件,mybatis的*mapper.xml文件
     /src/test/java目录用来存放java测试文件
     /src/test/resources目录用来存放测试资源文件
     /target目录为项目的输出位置
