用过spring Boot的小伙伴都会知道它的自动配置，毕竟spring Boot的两个重要策略就是开箱即用和约定优于配置。可是，开发应用时，程序怎么知道我们需要加载那些框架呢。
正常的springBoot的starter启动入口
@SpringBootApplication注解就是指明当前当前为SpringBoot应用，点进去之后会发现如下
这时就会发现@SpringBootApplication注解相当于这些注解的总和，其中@EnableAutoConfiguration注解就是自动配置的注解，在点进@EnableAutoConfiguration注解就会发现
这里导入了AutoConfigurationImportSelector类的是实例，点进这个类查看其源码就会发现它实现的具体原理，在这个类中，AutoConfigurationImportSelector类实现了DeferredImportSelector, BeanClassLoaderAware, ResourceLoaderAware, BeanFactoryAware, EnvironmentAware, Ordered这个几个接口，和包含了三个静态内部类，分别是 AutoConfigurationEntry ，AutoConfigurationGroup ，ConfigurationClassFilter。AutoConfigurationImportSelector类会先执行getImportGroup()这个方法，这个方法是实现了DeferredImportSelector接口的方法
public Class<? extends Group> getImportGroup() {
//返回的是当前类的AutoConfigurationGroup内部类的实例
return AutoConfigurationImportSelector.AutoConfigurationGroup.class;
}查看静态内部类AutoConfigurationGroup的源码
//该内部类实现了DeferredImportSelector 的 Group
private static class AutoConfigurationGroup implements Group, BeanClassLoaderAware, BeanFactoryAware, ResourceLoaderAware {
private final Map<String, AnnotationMetadata> entries = new LinkedHashMap();
private final List<AutoConfigurationImportSelector.AutoConfigurationEntry> autoConfigurationEntries = new ArrayList();
private ClassLoader beanClassLoader;
private BeanFactory beanFactory;
private ResourceLoader resourceLoader;
private AutoConfigurationMetadata autoConfigurationMetadata;
private AutoConfigurationGroup() {
}
public void setBeanClassLoader(ClassLoader classLoader) {
this.beanClassLoader = classLoader;
}
public void setBeanFactory(BeanFactory beanFactory) {
this.beanFactory = beanFactory;
}
public void setResourceLoader(ResourceLoader resourceLoader) {
this.resourceLoader = resourceLoader;
}
/**
*
**/
public void process(AnnotationMetadata annotationMetadata, DeferredImportSelector deferredImportSelector) {
//该方法为判断第一个参数是否为真，如果为假的时候会报出中断异常，报错内容为后面的信息
Assert.state(deferredImportSelector instanceof AutoConfigurationImportSelector, () -> {
//报错时，会报出以下错误
return String.format("Only %s implementations are supported, got %s", AutoConfigurationImportSelector.class.getSimpleName(), deferredImportSelector.getClass().getName());
});
//调用了getAutoConfigurationEntry这个方法，会获取各个包中/META-INF/spring.factories中的配置，这个位置是引入了SPI机制，进行过滤和排除处理，引入配置类和排除配置类，返回最终需要的配置类
AutoConfigurationImportSelector.AutoConfigurationEntry autoConfigurationEntry = ((AutoConfigurationImportSelector)deferredImportSelector).getAutoConfigurationEntry(annotationMetadata);
//将筛选出的用到的自动配置项放入到autoConfigurationEntries列表中
this.autoConfigurationEntries.add(autoConfigurationEntry);
//得到一个自动配置项的名称组成的迭代器
Iterator var4 = autoConfigurationEntry.getConfigurations().iterator();
while(var4.hasNext()) {
//获取自动配置项的名称
String importClassName = (String)var4.next();
//向其中添加键值对时，先判断是否其已存在，如果已存在将不会进行覆盖
this.entries.putIfAbsent(importClassName, annotationMetadata);
}
}
/**
* 处理单独的配置的导入和到处
**/
public Iterable<Entry> selectImports() {
//判断autoConfigurationEntries列表是否有值
if (this.autoConfigurationEntries.isEmpty()) {
return Collections.emptyList();
} else {
//得到自定义的一些需要配置
Set<String> allExclusions = (Set)this.autoConfigurationEntries.stream().map(AutoConfigurationImportSelector.AutoConfigurationEntry::getExclusions).flatMap(Collection::stream).collect(Collectors.toSet());
//得到系统所有的配置
Set<String> processedConfigurations = (Set)this.autoConfigurationEntries.stream().map(AutoConfigurationImportSelector.AutoConfigurationEntry::getConfigurations).flatMap(Collection::stream).collect(Collectors.toCollection(LinkedHashSet::new));
//从所有配置中去除需要过滤掉的配置
processedConfigurations.removeAll(allExclusions);
//将自定义需要引入的配置返回
return (Iterable)this.sortAutoConfigurations(processedConfigurations, this.getAutoConfigurationMetadata()).stream().map((importClassName) -> {
return new Entry((AnnotationMetadata)this.entries.get(importClassName), importClassName);
}).collect(Collectors.toList());
}
}
private AutoConfigurationMetadata getAutoConfigurationMetadata() {
if (this.autoConfigurationMetadata == null) {
this.autoConfigurationMetadata = AutoConfigurationMetadataLoader.loadMetadata(this.beanClassLoader);
}
return this.autoConfigurationMetadata;
}
private List<String> sortAutoConfigurations(Set<String> configurations, AutoConfigurationMetadata autoConfigurationMetadata) {
return (new AutoConfigurationSorter(this.getMetadataReaderFactory(), autoConfigurationMetadata)).getInPriorityOrder(configurations);
}
private MetadataReaderFactory getMetadataReaderFactory() {
try {
return (MetadataReaderFactory)this.beanFactory.getBean("org.springframework.boot.autoconfigure.internalCachingMetadataReaderFactory", MetadataReaderFactory.class);
} catch (NoSuchBeanDefinitionException var2) {
return new CachingMetadataReaderFactory(this.resourceLoader);
}
}
}在上面这段代码中，为了加载配置项调用了一个重要方法 getAutoConfigurationEntry，这个方法
protected AutoConfigurationImportSelector.AutoConfigurationEntry getAutoConfigurationEntry(AnnotationMetadata annotationMetadata) {
if (!this.isEnabled(annotationMetadata)) {
return EMPTY_ENTRY;
} else {
//获取注解元数据的属性
AnnotationAttributes attributes = this.getAttributes(annotationMetadata);
//获取自动配置的类，在这个位置调用了getCandidateConfigurations方法，此方法为了处理加载配置
List<String> configurations = this.getCandidateConfigurations(annotationMetadata, attributes);
//去除list列表中重复项，这里采用的LinkedHashSet列表的特性来处理重复的
configurations = this.removeDuplicates(configurations);
//获取单独配置的加载项，这个位置调用了getExclusions方法进行处理的
Set<String> exclusions = this.getExclusions(annotationMetadata, attributes);
//检查是否存在要排除配置项
this.checkExcludedClasses(configurations, exclusions);
//去除要删除的配置项
configurations.removeAll(exclusions);
//调用ConfigurationClassFilter静态内部类的filter过滤器，将用不到的配置项去掉
configurations = this.getConfigurationClassFilter().filter(configurations);
//触发自动化配置的导入事件
this.fireAutoConfigurationImportEvents(configurations, exclusions);
return new AutoConfigurationImportSelector.AutoConfigurationEntry(configurations, exclusions);
}
}上面的类中调用了 getCandidateConfigurations方法，该方法实现了SPI机制，此方法的源码为：
protected List<String> getCandidateConfigurations(AnnotationMetadata metadata, AnnotationAttributes attributes) {
//调用了SpringFactoriesLoader类中的loadFactoryNames方法，用于加载所有的配置项
List<String> configurations = SpringFactoriesLoader.loadFactoryNames(this.getSpringFactoriesLoaderFactoryClass(), this.getBeanClassLoader());
//如果配置项为控，则会进行后面第二个参数的错误
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;
}查看SpringFactoriesLoader类中的loadFactoryNames方法源码
public static List<String> loadFactoryNames(Class<?> factoryType, @Nullable ClassLoader classLoader) {
ClassLoader classLoaderToUse = classLoader;
//如果传递的类加载器为空，则使用SpringFactoriesLoader类加载器
if (classLoader == null) {
classLoaderToUse = SpringFactoriesLoader.class.getClassLoader();
}
//此时的factoryTypeName的值为org.springframework.boot.autoconfigure.EnableAutoConfiguration
String factoryTypeName = factoryType.getName();
//loadSpringFactories方法是获取指定接口的实现类对象。getOrDefault是Map类下的方法，意思是根据键对应的值不为空，则返回该值，为空返回默认值
return (List)loadSpringFactories(classLoaderToUse).getOrDefault(factoryTypeName, Collections.emptyList());
}由上面一段代码可知，主要是由loadSpringFactories方法处理的，查看loadSpringFactories方法代码
private static Map<String, List<String>> loadSpringFactories(ClassLoader classLoader) {
Map<String, List<String>> result = (Map)cache.get(classLoader);
if (result != null) {
return result;
} else {
HashMap result = new HashMap();
try {
//扫描所有包路径下的META-INF/spring.factories文件
Enumeration urls = classLoader.getResources("META-INF/spring.factories");
while(urls.hasMoreElements()) {
//拿出其中一个包路径下的META-INF/spring.factories文件
URL url = (URL)urls.nextElement();
//根据META-INF/spring.factories文件问价路径获得资源
UrlResource resource = new UrlResource(url);
//将响应资源包装成Properties对象
Properties properties = PropertiesLoaderUtils.loadProperties(resource);
//将对象内容进行迭代
Iterator var6 = properties.entrySet().iterator();
while(var6.hasNext()) {
Entry<?, ?> entry = (Entry)var6.next();
//获取Properties对象中的key值
String factoryTypeName = ((String)entry.getKey()).trim();
//获取Properties对象中的value值，使用逗号为分隔符转化数组，数组内的每个元素都是配置类的完全限制名
String[] factoryImplementationNames = StringUtils.commaDelimitedListToStringArray((String)entry.getValue());
String[] var10 = factoryImplementationNames;
int var11 = factoryImplementationNames.length;
//将数组转化为集合
for(int var12 = 0; var12 < var11; ++var12) {
String factoryImplementationName = var10[var12];
((List)result.computeIfAbsent(factoryTypeName, (key) -> {
return new ArrayList();
})).add(factoryImplementationName.trim());
}
}
}
//将Properties对象中的key值和配置类组成的list集合存入到resultMap中
result.replaceAll((factoryType, implementations) -> {
return (List)implementations.stream().distinct().collect(Collectors.collectingAndThen(Collectors.toList(), Collections::unmodifiableList));
});
cache.put(classLoader, result);
return result;
} catch (IOException var14) {
throw new IllegalArgumentException("Unable to load factories from location [META-INF/spring.factories]", var14);
}
}
}上面的源码中多次提到spring.factories文件，选择一个包下的spring.factories文件内容展示。当一个键有多个值时，就用逗号（，）分隔，利用反斜杠（\）进行换行
