+# 模块化引用示例
+
+## 介绍
+
+本示例为模块化引用示例。
+
+## 效果图预览
+
+  <img src="./entry/src/main/resources/base/media/moduleSample.png" width="300">
+
+  **场景说明**
+    1. 懒加载机制默认实现：引入但未使用的类不会被加载。
+    2. export出来的类，其余未export的情况不会加载。
+    3. har包引入后，未使用的情况下不加载。
+
+## 实现思路
+### 场景1：懒加载机制默认实现：引入但未使用的类不会被加载。
+
+- 在mod1.ets文件内写入类Mod1以及一条打印日志的顶层语句，Mod1类内包含一个静态代码块，静态代码块内为打印日志语句。
+- 在Index.ets文件内导入Mod1.ets文件，不点击按钮"import"时，Mod1为引入但未使用的类，此时不会打印"executeModule mod1"以及"executeModule import 顶层语句"日志。
+- 点击按钮时，使用Mod1类，此时才会打印"executeModule mod1"日志。"executeModule import 顶层语句"日志为顶层语句不会被打印。
+
+```typescript
+// mod1.ets
+export class Mod1 {
+  static name: string = 'mod';
+  static {
+    hilog.info(0x0000, 'testTag', "executeModule mod1");
+  }
+}
+hilog.info(0x0000, 'testTag', "executeModule import 顶层语句");
+```
+```typescript
+// Index.ets
+import { Mod1 } from './mod/mod1';
+@Component
+struct MyStateSample {
+  build() {
+    ...
+    Button("import")
+      .width('60%')
+      .onClick((e: ClickEvent) => {
+        let mod1 = new Mod1();
+      })
+    ...
+  }
+}
+```
+### 场景2：export出来的类，其余未export的情况不会加载。
+#### 2.1 顶层语句不会被加载
+
+- 在mod2.ets文件内包含一个导出类Mod2以及一条打印日志的顶层语句，Mod2类内包含一个静态代码块，静态代码块内为打印日志语句。
+- 在Index.ets文件内导入Mod2.ets文件，点击"export1"按钮时，Mod2.ets文件内未导出的顶层语句不会被加载，不会打印日志"executeModule export 顶层语句"。
+
+```typescript
+// mod2.ets
+export class Mod2 {
+  static name: string = '';
+  static {
+    hilog.info(0x0000, 'testTag', "executeModule mod2");
+  }
+}
+hilog.info(0x0000, 'testTag', "executeModule export 顶层语句");
+```
+```typescript
+// Index.ets
+import { Mod2 } from './mod/mod2';
+@Component
+struct MyStateSample {
+  build() {
+    ...
+    Button("export1")
+      .width('60%')
+      .onClick((e: ClickEvent) => {
+        let mod2 = new Mod2();
+      })
+    ...
+  }
+}
+```
+#### 2.2 其余未导出的类不会被加载
+
+- mod3文件内导出内容有：五个类，类名分别为A,B,C,D,E，A类内有一个静态成员变量count，值为1，A类的静态代码块只有hilog语句，顶层代码将A.count设置为100。 B,C,D,E内的静态成员变量count默认值为0，B,C,D,E内的静态代码块将每个类的count的值设置为++A.count。
+- 在Index文件内导入两个类A和E，arkts1.0 export时所有类都会export，因此A.count经过四次增加，以及一次顶层语句的赋值，E.count的值为105。其余export的类不加载，E.count的值应该为2，仅导入两个类A和E。
+
+```typescript
+// mod3.ets
+import hilog from '@ohos.hilog'
+export class A {
+  static count = 1;
+  static {
+    hilog.info(0x0000, 'testTag', "executeModule execute A");
+  }
+}
+A.count = 101;
+export class B {
+  static count = 0;
+  static {
+    B.count = ++A.count;
+    hilog.info(0x0000, 'testTag', "executeModule execute B");
+  }
+}
+
+export class C {
+  static count = 0;
+  static {
+    C.count = ++A.count;
+    hilog.info(0x0000, 'testTag', "executeModule execute C");
+  }
+}
+export class D {
+  static count = 0;
+  static {
+    D.count = ++A.count;
+    hilog.info(0x0000, 'testTag', "executeModule execute D");
+  }
+}
+export class E {
+  static count = 0;
+  static {
+    E.count = ++A.count;
+    hilog.info(0x0000, 'testTag', "executeModule execute E");
+  }
+}
+```
+```typescript
+// Index.ets
+import { A, E } from './mod/mod3';
+@Component
+struct MyStateSample {
+  build() {
+    ...
+    Button("export2")
+      .width('60%')
+      .onClick((e: ClickEvent) => {
+        let modA = new A();
+        let modE = new E();
+        let promptAction: PromptAction = this.uiContext!.getPromptAction();
+        promptAction.showToast({
+          message: '共加载了 E.count: ' + E.count + '个类',
+          duration: 20000
+        });
+      })
+    ...
+  }
+}
+```
+
+#### 2.3 通过耗时验证其余未导出的类没有被加载
+- mod4.ets文件包含一个导出类ExportSmallClassTest，如果这个类被加载会运行静态模块，在静态模块内将此时的时间记录到静态成员变量exportTime中。
+- 在exportTestPage1.ets文件内，将mod4.ets中导出的类ExportSmallClassTest导入，导入后用现在的时间减去ExportSmallClassTest类中的exportTime就是导入耗时，将耗时写到Text组件，显示到界面上。
+- mod5.ets文件里面包括两个类，ExportSmallClass和ExportBigClass，ExportSmallClass和在mod4中的ExportSmallClassTest类的内容完全一致，静态成员变量isExportOtherClass默认值为false，ExportBigClass是一个有15000多个成员变量的超大类，在这个类的静态代码块中将ExportSmallClass.isExportOtherClass置为true。如果加载了这个超大类，ExportSmallClass的静态成员变量isExportOtherClass的值将置为true。
+- 在exportTestPage2.ets页面导入mod5中的ExportSmallClass类，将耗时记录下来，显示在界面上。并判断ExportSmallClass.isExportOtherClass是否为true，如果为true则代表超大类也导出了，此时显示文本“不需要的类也加载了”。
+```typescript
+// mod4.ets
+import hilog from '@ohos.hilog'
+
+export class ExportSmallClassTest {
+  static exportTime: double = 0;
+  static isExportOtherClass = false;
+  static {
+    ExportSmallClassTest.exportTime = Date.now();
+    hilog.info(0x0000, 'testTag', "executeModule mod4 smallclass");
+  }
+  static na = 'zhangsan';
+}
+```
+```typescript
+// exportTestPage1.ets
+import { ExportSmallClassTest } from './mod/mod4';
+let exportTime: double = ExportSmallClassTest.exportTime;
+let dur = Date.now() - exportTime;
+@Entry
+@Component
+struct page1 {
+  @State message: string = "预期结果";
+  build() {
+    Column() {
+      Text('page1')
+        .fontSize(30)
+      Text('耗时' + dur + 'ms')
+        .fontSize(20)
+      Button("back")
+        .onClick((e: ClickEvent) => {
+          this.getUIContext().getRouter().back();
+        })
+    }
+    .width('100%')
+    .height('100%')
+  }
+}
+```
+```typescript
+// mod5.ets
+import hilog from '@ohos.hilog'
+export class ExportSmallClass {
+  static exportTime: double = 0;
+  static isExportOtherClass = false;
+  static {
+    ExportSmallClass.exportTime = Date.now();
+    hilog.info(0x0000, 'testTag', "executeModule mod5 smallclass");
+  }
+  static na = 'zhangsan';
+}
+  export class ExportBigClass {
+  static exportTime: double = 0;
+  static {
+    ExportBigClass.exportTime = Date.now();
+    ExportSmallClass.isExportOtherClass = true;
+    hilog.info(0x0000, 'testTag', "executeModule mod5 bigclass");
+  }
+  static attribute_0 = 0;
+  static attribute_1 = 1;
+  static attribute_2 = 2;
+  static attribute_3 = 3;
+  ...
+  static attribute_15000 = 15000;
+}
+```
+```typescript
+// exportTestPage2.ets
+import { ExportSmallClass } from './mod/mod5';
+let exportTime: double = ExportSmallClass.exportTime;
+let dur = Date.now() - exportTime;
+@Entry
+@Component
+struct page2 {
+  build() {
+    Column() {
+      Text('page2')
+        .fontSize(30)
+      Text('耗时' + dur + 'ms')
+        .fontSize(20)
+      if(ExportSmallClass.isExportOtherClass) {
+        Text('不需要的类也加载了')
+      }
+      Button("back")
+        .onClick((e: ClickEvent) => {
+          this.getUIContext().getRouter().back();
+        })
+    }
+    .width('100%')
+      .height('100%')
+  }
+}
+```
+### 场景3：har包引入后，未使用的情况下不加载。
+
+- 在项目中新建har包，命名为ImportHar。
+- 在har包内MainPage.ets页面。
+- 点击按钮时，使用Mod1类，此时才会打印"executeModule mod1"日志。"executeModule import 顶层语句"日志为顶层语句不会被打印。
+
+```typescript
+// ImportHar/src/main/ets/components/MainPage.ets
+import hilog from '@ohos.hilog'
+export class Har {
+  static {
+    hilog.info(0x0000, 'testTag', "executeModule mod 导入har包");
+  }
+}
+  ```
+```typescript
+// Index.ets
+import { Har } from 'importhar';
+@Component
+struct MyStateSample {
+  build() {
+    ...
+    Button("import har")
+      .width('60%')
+      .onClick((e: ClickEvent) => {
+        let har = new Har();
+      })
+    ...
+  }
+}
+```
