SpringBoot：配置文件及自動配置原理

配置文件

SpringBoot使用一個全局的配置文件，配置文件名稱是固定的git

application.properties
- 語法結構： key=value
application.yml
- 語法結構：key：空格 value

配置文件的做用：修改SpringBoot自動配置的默認值，由於SpringBoot在底層都給咱們自動配置好了；
github

YAML

YAML是 "YAML Ain't a Markup Language" （YAML不是一種置標語言）的遞歸縮寫。

在開發的這種語言時，YAML 的意思實際上是："Yet Another Markup Language"（還是一種置標語言）

YAML A Markup Language ：是一個標記語言

YAML isnot Markup Language ：不是一個標記語言

標記語言web

之前的配置文件，大多數都是使用xml來配置；好比一個簡單的端口配置，咱們來對比下yaml和xml面試

yaml配置：redis

server：
    prot: 8080

xml配置：spring

<server>
    <port>8081<port>
</server>

YAML語法

基礎語法：mongodb

k:(空格) v

以此來表示一對鍵值對（空格不能省略）；以空格的縮進來控制層級關係，只要是左邊對齊的一列數據都是同一個層級的。

注意：屬性和值的大小寫都是十分敏感的。例子：

server:
    port: 8081
    path: /hello

值的寫法

字面量：普通的值 [ 數字，布爾值，字符串 ]

k: v

字面量直接寫在後面就能夠，字符串默認不用加上雙引號或者單引號；

「」雙引號，不會轉義字符串裏面的特殊字符，特殊字符會做爲自己想表示的意思；

好比： name: "kuang \n shen" 輸出： kuang 換行 shen

'' 單引號，會轉義特殊字符，特殊字符最終會變成和普通字符同樣輸出

好比： name: ‘kuang \n shen’ 輸出： kuang \n shen

對象、Map（鍵值對）

k: 
    v1:
    v2:

在下一行來寫對象的屬性和值得關係，注意縮進；好比：

student:
    name: qinjiang
    age: 3

行內寫法

student: {name: qinjiang,age: 3}

數組（ List、set ）

用 - 值表示數組中的一個元素,好比：

pets:
 - cat
 - dog
 - pig

行內寫法

pets: [cat,dog,pig]

修改SpringBoot的默認端口號

配置文件中添加，端口號的參數，就能夠切換端口；

server.port=8081

注入配置文件

程序實現

1. 若是要使用properties配置文件可能導入時存在亂碼現象，須要在IDEA中進行調整，咱們這裏直接使用yml文件，將默認的 application.properties後綴修改成yml

2. 導入配置文件處理器

<!--導入配置文件處理器，配置文件進行綁定就會有提示-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

3.編寫yml 配置文件

person:
    name: qinjiang
    age: 3
    happy: false
    birth: 2000/01/01
    maps: {k1: v1,k2: v2}
    lists:
      - code
      - girl
      - music
    dog:
      name: 旺財
      age: 1

4.在SpringBoot的主程序的同級目錄下建包，只有這樣，主程序纔會對這些類生效；咱們建一個pojo的包放入咱們的Person類和Dog類；

package com.kuang.springbootdemo03.pojo;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.Date;
import java.util.List;
import java.util.Map;


/*
@ConfigurationProperties做用：
將配置文件中配置的每個屬性的值，映射到這個組件中；
告訴SpringBoot將本類中的全部屬性和配置文件中相關的配置進行綁定
參數 prefix = 「person」 : 將配置文件中的person下面的全部屬性一一對應

只有這個組件是容器中的組件，才能使用容器提供的@ConfigurationProperties功能
*/
@Component //註冊bean
@ConfigurationProperties(prefix = "person")
public class Person {

    private String name;
    private Integer age;
    private Boolean happy;
    private Date birth;
    private Map<String,Object> maps;
    private List<Object> lists;
    private Dog dog;

    //get,set方法
    //toString方法
    
}

記得寫上 toString（）方法，方便調試輸出結果

package com.kuang.springbootdemo03.pojo;

public class Dog {
    private String name;
    private Integer age;
    
    //get、set方法
    //toString()方法  
}

5.確認無誤後，到測試單元中進行測試，看是否注入成功！

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootDemo03ApplicationTests {

    @Autowired
    Person person = new Person();

    @Test
    public void contextLoads() {
        System.out.println(person);
    }

}

運行結果

嘮叨兩句

咱們上面採用的方法都是最簡單的方式，開發中最經常使用的；

那咱們來嘮嘮其餘的實現方式，道理都是相同得；寫仍是那樣寫；

配置文件除了yml還有咱們以前經常使用的properties ，咱們沒有講， properties配置文件在寫中文的時候，會有亂碼，咱們須要去IDEA中設置編碼格式爲UTF-8；

settings-->FileEncodings 中配置；

還有，咱們的類和配置文件直接關聯着，咱們使用的是@configurationProperties的方式，還有一種方式是使用@value

@Component //註冊bean
public class Person {
    //直接使用@value
    @Value("${person.name}") //從配置文件中取值
    private String name;
    @Value("#{11*2}")  //#{SPEL} Spring表達式
    private Integer age;
    @Value("true")  // 字面量
    private Boolean happy;
    
    。。。。。。  
}

結果

這個使用起來並不友好！咱們須要爲每一個屬性單獨註解賦值，比較麻煩；咱們來看個功能對比圖

cp只須要寫一次便可， value則須要每一個字段都添加
鬆散綁定：這個什麼意思呢? 好比個人yml中寫的last-name，這個和lastName是同樣的， - 後面跟着的字母默認是大寫的。這就是鬆散綁定
JSR303數據校驗，這個就是咱們能夠在字段是增長一層過濾器驗證，能夠保證數據的合法性
複雜類型封裝，yml中能夠封裝對象，使用@value就不支持

結論：

配置yml和配置properties均可以獲取到值，強烈推薦 yml
若是咱們在某個業務中，只須要獲取配置文件中的某個值，可使用一下 @value
若是說，咱們專門編寫了一個JavaBean來和配置文件進行映射，就直接使用@configurationProperties，不要猶豫！

JSR303數據校驗

spring-boot中能夠用@validated來校驗數據，若是數據異常則會統一拋出異常，方便異常中心統一處理。咱們這裏來寫個註解讓咱們的name只能支持Email格式

@Component //註冊bean
@ConfigurationProperties(prefix = "person")
@Validated  //數據校驗
public class Person {

    //@Value("${person.name}")
    @Email //name必須是郵箱格式
    private String name;
}

運行結果

使用數據校驗，能夠保證數據的正確性；

加載指定配置文件

1. @PropertySource ：加載指定的配置文件；使用@configurationProperties默認從全局配置文件中獲取值；

咱們去在resources目錄下新建一個person.properties文件

name=kuangshen

而後在咱們的代碼中指定加載person.properties文件

@PropertySource(value = "classpath:person.properties")
@Component //註冊bean
public class Person {

    @Value("${name}")
    private String name;

    ......  
}

測試結果：

配置文件佔位符

隨機數

${random.value}、${random.int}、${random.long}、${random.int(10)}等等

佔位符引用其餘屬性的值，若是不存在能夠設置默認值

person:
    name: qinjiang${random.uuid}
    age: ${random.int}
    happy: false
    birth: 2000/01/01
    maps: {k1: v1,k2: v2}
    lists:
      - code
      - girl
      - music
    dog:
      name: ${person.hello:hello}_旺財
      age: 1

多環境切換

profile是Spring對不一樣環境提供不一樣配置功能的支持，能夠經過激活不一樣的環境版本，實現快速切換環境；

方式一：多配置文件

咱們在主配置文件編寫的時候，文件名能夠是 application-{profile}.properties/yml ，用來指定多個環境版本；

例如：application-test.properties 表明測試環境配置 application-dev.properties 表明開發環境配置

可是Springboot並不會直接啓動這些配置文件，它默認使用application.properties主配置文件；

咱們須要經過一個配置來選擇須要激活的環境；

#好比在配置文件中指定使用dev環境，咱們能夠經過設置不一樣的端口號進行測試；
#咱們啓動SpringBoot，就能夠看到已經切換到dev下的配置了；
spring.profiles.active=dev

方式二：yml的多文檔塊

和properties配置文件中同樣，可是使用yml去實現不須要建立多個配置文件，更加方便了

server:
  port: 8081
#選擇要激活那個環境塊
spring:
  profiles:
    active: prod

---
server:
  port: 8083
#配置環境的名稱
spring:
  profiles: dev


---

server:
  port: 8084
spring:
  profiles: prod  #配置環境的名稱

注意：若是yml和properties同時都配置了端口，而且沒有激活其餘環境，默認會使用properties配置文件的！

配置文件加載位置

springboot 啓動會掃描如下位置的application.properties或者application.yml文件做爲Spring boot的默認配置文件

優先級1：項目路徑下的config文件夾配置文件
優先級2：項目路徑下配置文件
優先級3：資源路徑下的config文件夾配置文件
優先級4：資源路徑下配置文件

優先級由高到底，高優先級的配置會覆蓋低優先級的配置；

SpringBoot會從這四個位置所有加載主配置文件；互補配置；

咱們在最低級的配置文件中設置一個項目訪問路徑的配置來測試互補問題；

#配置項目的訪問路徑
server.servlet.context-path=/kuang

【擴展】指定位置加載配置文件

咱們還能夠經過spring.config.location來改變默認的配置文件位置

項目打包好之後，咱們可使用命令行參數的形式，啓動項目的時候來指定配置文件的新位置；

這種狀況，通常是後期運維作的多，相同配置，外部指定的配置文件優先級最高

java -jar spring-boot-config.jar --spring.config.location=F:/application.properties

外部加載配置文件的方式十分多，咱們選擇最經常使用的便可，在開發的資源文件中進行配置！

官方外部配置文件說明參考文檔

自動配置原理

配置文件到底能寫什麼？怎麼寫？

SpringBoot官方文檔

分析自動配置原理

1. SpringBoot啓動的時候加載主配置類，開啓了自動配置功能 @EnableAutoConfiguration

2. @EnableAutoConfiguration 做用：

利用EnableAutoConfigurationImportSelector給容器中導入一些組件，導入了哪些組件呢？
能夠查看這個類selectImports()方法的內容，他返回了一個 autoConfigurationEntry , 來自 this.getAutoConfigurationEntry(autoConfigurationMetadata, annotationMetadata); 這個方法。咱們繼續跟蹤；
這個方法中有一個值： List<String> configurations = this.getCandidateConfigurations(annotationMetadata, attributes); 叫作獲取候選的配置，咱們點擊去繼續跟蹤；

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;
}

這裏裏面有一個 SpringFactoriesLoader.loadFactoryNames() ，咱們繼續進去看 , 它又調用了 loadSpringFactories 方法；繼續跟蹤。發現它去得到了一個資源文件："META-INF/spring.factories"

```
Enumeration<URL> urls = classLoader != null ? classLoader.getResources("META-INF/spring.factories") : ClassLoader.getSystemResources("META-INF/spring.factories");
```
繼續閱讀源碼，它將讀取到的資源封裝在url中，而後遍歷url ，將這些url文件封裝在Properties文件中；最後返回封裝好的結果；他的那個ClassLoader參數，咱們追蹤回去，看到他就是 EnableAutoConfiguration ；
說明了這個邏輯就是從properties中獲取到EnableAutoConfiguration.class類（類名）對應的值，而後把他們添加在容器中
總結一句話就是：將類路徑下 META-INF/spring.factories 裏面配置的全部EnableAutoConfiguration的值加入到了容器中；咱們從源碼中拿過來

每個這樣的 xxxAutoConfiguration類都是容器中的一個組件，最後都加入到容器中；用他們來作自動配置；

3. 每個自動配置類能夠進行自動配置功能；

4. 咱們以HttpEncodingAutoConfiguration（Http編碼自動配置）爲例解釋自動配置原理；

@Configuration //表示這是一個配置類，之前編寫的配置文件同樣，也能夠給容器中添加組件
//啓動指定類的ConfigurationProperties功能；
//進入這個HttpProperties查看，將配置文件中對應的值和HttpProperties綁定起來；
//並把HttpProperties加入到ioc容器中
@EnableConfigurationProperties({HttpProperties.class}) 

//Spring底層@Conditional註解
//根據不一樣的條件判斷，若是知足指定的條件，整個配置類裏面的配置就會生效；
//這裏的意思就是判斷當前應用是不是web應用，若是是，當前配置類生效
@ConditionalOnWebApplication(
    type = Type.SERVLET
)

//判斷當前項目有沒有這個類CharacterEncodingFilter；SpringMVC中進行亂碼解決的過濾器；
@ConditionalOnClass({CharacterEncodingFilter.class})

//判斷配置文件中是否存在某個配置：spring.http.encoding.enabled；
//若是不存在，判斷也是成立的
//即便咱們配置文件中不配置pring.http.encoding.enabled=true，也是默認生效的；
@ConditionalOnProperty(
    prefix = "spring.http.encoding",
    value = {"enabled"},
    matchIfMissing = true
)

public class HttpEncodingAutoConfiguration {

    //他已經和SpringBoot的配置文件映射了
    private final Encoding properties;

    //只有一個有參構造器的狀況下，參數的值就會從容器中拿
    public HttpEncodingAutoConfiguration(HttpProperties properties) {
        this.properties = properties.getEncoding();
    }

    //給容器中添加一個組件，這個組件的某些值須要從properties中獲取
    @Bean
    @ConditionalOnMissingBean //判斷容器沒有這個組件？
    public CharacterEncodingFilter characterEncodingFilter() {
        CharacterEncodingFilter filter = new OrderedCharacterEncodingFilter();
        filter.setEncoding(this.properties.getCharset().name());
        filter.setForceRequestEncoding(this.properties.shouldForce(org.springframework.boot.autoconfigure.http.HttpProperties.Encoding.Type.REQUEST));
        filter.setForceResponseEncoding(this.properties.shouldForce(org.springframework.boot.autoconfigure.http.HttpProperties.Encoding.Type.RESPONSE));
        return filter;
    }
    。。。。。。
}

一句話總結：根據當前不一樣的條件判斷，決定這個配置類是否生效！

一但這個配置類生效；這個配置類就會給容器中添加各類組件；這些組件的屬性是從對應的properties類中獲取的，這些類裏面的每個屬性又是和配置文件綁定的；

5. 全部在配置文件中能配置的屬性都是在xxxxProperties類中封裝者‘；配置文件能配置什麼就能夠參照某個功能對應的這個屬性類

@ConfigurationProperties(
    prefix = "spring.http"
) //從配置文件中獲取指定的值和bean的屬性進行綁定
public class HttpProperties {
    private boolean logRequestDetails;
    private final HttpProperties.Encoding encoding = new HttpProperties.Encoding();

    public HttpProperties() {
    }

    public boolean isLogRequestDetails() {
        return this.logRequestDetails;
    }

    public void setLogRequestDetails(boolean logRequestDetails) {
        this.logRequestDetails = logRequestDetails;
    }

    public HttpProperties.Encoding getEncoding() {
        return this.encoding;
    }

    public static class Encoding {
        public static final Charset DEFAULT_CHARSET;
        private Charset charset;
        private Boolean force;
        private Boolean forceRequest;
        private Boolean forceResponse;
        private Map<Locale, Charset> mapping;
        
        、、、、、、
    }
}

咱們去配置文件裏面試試前綴，看提示！

這就是自動裝配的原理！

精髓：

1）、SpringBoot啓動會加載大量的自動配置類

2）、咱們看咱們須要的功能有沒有在SpringBoot默認寫好的自動配置類當中；

3）、咱們再來看這個自動配置類中到底配置了哪些組件；（只要咱們要用的組件存在在其中，咱們就不須要再手動配置了）

4）、給容器中自動配置類添加組件的時候，會從properties類中獲取某些屬性。咱們只須要在配置文件中指定這些屬性的值便可；

xxxxAutoConfigurartion：自動配置類；給容器中添加組件

xxxxProperties:封裝配置文件中相關屬性；

@Conditional

瞭解完自動裝配的原理後，咱們來關注一個細節問題，自動配置類必須在必定的條件下才能生效；

@Conditional派生註解（Spring註解版原生的@Conditional做用）

做用：必須是@Conditional指定的條件成立，纔給容器中添加組件，配置配裏面的全部內容才生效；

那麼多的自動配置類，必須在必定的條件下才能生效；也就是說，咱們加載了這麼多的配置類，但不是全部的都生效了。

咱們怎麼知道哪些自動配置類生效；咱們能夠經過啓用 debug=true屬性；來讓控制檯打印自動配置報告，這樣咱們就能夠很方便的知道哪些自動配置類生效；

#開啓springboot的調試類
debug=true

Positive matches:（自動配置類啓用的：正匹配）

Negative matches:（沒有啓動，沒有匹配成功的自動配置類：負匹配）

Unconditional classes: （沒有條件的類）

輸出的日誌咱們能夠在這裏看下：
