+
+#### 框架初始化步骤-源代码
+
+> SpringBoog启动类：org.springframework.boot.SpringApplication
+
+```java
+	@SuppressWarnings({ "unchecked", "rawtypes" })
+	public SpringApplication(ResourceLoader resourceLoader, Class<?>... primarySources) {
+    // 配置资源加载器
+		this.resourceLoader = resourceLoader;
+		Assert.notNull(primarySources, "PrimarySources must not be null");
+    
+    // 配置primarySources
+		this.primarySources = new LinkedHashSet<>(Arrays.asList(primarySources));
+    
+    // 应用环境检测
+		this.webApplicationType = WebApplicationType.deduceFromClasspath();
+    
+    // 配置系统初始化器
+		setInitializers((Collection) getSpringFactoriesInstances(ApplicationContextInitializer.class));
+    
+    // 配置应用监听器
+		setListeners((Collection) getSpringFactoriesInstances(ApplicationListener.class));
+    
+    // 配置main方法所在的类
+		this.mainApplicationClass = deduceMainApplicationClass();
+	}
+```
