+## 编写Spring应用
+
+### `@SpringBootApplication` 注解
+
+1. **`@EnableAutoConfiguration`**：
+   - 这个注解让 Spring Boot 根据项目中的依赖，自动配置 Spring 应用程序。Spring Boot 提供了大量的自动配置支持，帮助我们省去手动配置许多常见的功能。
+   - 例如，如果你的项目中加入了 `spring-boot-starter-web` 依赖，Spring Boot 会自动配置一个嵌入式的 Tomcat 服务器和一些常见的 Web 功能。
+2. **`@ComponentScan`**：
+   - 这个注解启用 Spring 的组件扫描机制。它会扫描当前类所在的包及其子包，自动发现并注册 `@Component`、`@Service`、`@Repository`、`@Controller` 等注解标注的类。
+   - 通过 `@ComponentScan`，你不需要手动指定要扫描的包，Spring Boot 会自动扫描当前包及其子包下的所有组件。
+3. **`@Configuration`**：
+   - 这个注解表示该类是一个 Spring 配置类，类似于 XML 配置文件，用于定义 Spring 应用的 Bean 配置。
+   - 该类可以包含 `@Bean` 注解的方法，返回要管理的 Bean。
+
+### `@SpringBootTest` 注解
+
+`@SpringBootTest` 注解是用于测试 Spring Boot 应用的一个重要注解，它提供了一种方便的方式来启动 Spring Boot 应用上下文，并对整个 Spring Boot 应用进行集成测试。这个注解本身也包含了多个注解，它使得我们能够在测试类中创建一个完整的 Spring 容器来进行集成测试。
+
+具体来说，`@SpringBootTest` 是一个组合注解，它整合了以下几个主要的注解：
+
+1. **`@ContextConfiguration`**：
+   - `@ContextConfiguration` 注解用于加载 Spring 配置文件或者配置类，在测试时会初始化 Spring 容器。`@SpringBootTest` 默认会加载 Spring Boot 应用的主配置类（即包含 `@SpringBootApplication` 注解的类），作为 Spring 容器的上下文。
+   - 它的作用是让测试类能够加载到 Spring 配置并创建一个完整的应用上下文。
+2. **`@TestExecutionListeners`**：
+   - 该注解指定了测试执行时的监听器。在 Spring 测试框架中，`@TestExecutionListeners` 会提供某些扩展功能，如事务管理、环境配置等，但它的实际作用在大多数测试中不太明显，通常由 Spring Boot 自动配置。
+3. **`@DirtiesContext`**：
+   - 这个注解会告诉 Spring 在测试执行之后清除（或重置）应用上下文，通常用于测试中的应用上下文需要被清理或重置，以避免测试间的相互影响。`@SpringBootTest` 会根据需要处理上下文的清理工作。
+4. **`@BootstrapWith`**：
+   - 这个注解是用于引导测试的，它会指定 `SpringBootTestContextBootstrapper` 来启动 Spring Boot 测试上下文。这是一个 Spring Boot 测试框架中的内部机制，用于初始化应用上下文并准备测试。

+## Spring 表单验证
+
+在 Spring MVC 中，表单验证是通过一系列的注解来完成的。
+
+### **`@NotNull`**
+
+- **作用**：确保字段值不为空。
+
+- **用法**：用于字段、方法参数或返回值上，表示该字段不能为空。如果字段为空，将验证失败并返回相应的错误信息。
+
+- 示例
+
+  ```java
+  @NotNull(message = "用户名不能为空")
+  private String username;
+  ```
+
+### **`@NotEmpty`**
+
+- **作用**：确保字段不为空，并且不为一个空字符串。
+
+- **用法**：用于字符串、集合等类型，验证字段不仅不能为空，而且不能为空字符串。
+
+- 示例
+
+  ```java
+  @NotEmpty(message = "密码不能为空")
+  private String password;
+  ```
+
+### **`@NotBlank`**
+
+- **作用**：确保字段不为空，并且不为一个空白字符串（即非空白字符）。
+
+- **用法**：类似于 `@NotEmpty`，但除了不为空，还要求去除空白字符后不能为零长度。
+
+- 示例
+
+  ```java
+  @NotBlank(message = "电子邮件不能为空")
+  private String email;
+  ```
+
+### **`@Size(min, max)`**
+
+- **作用**：验证字段的大小，适用于字符串、集合、数组等类型。
+
+- **用法**：可以设置最小值和最大值来限制字段的长度或集合的大小。
+
+- 示例
+
+  ```java
+  @Size(min = 6, max = 20, message = "密码长度必须在6到20之间")
+  private String password;
+  ```
+
+### **`@Email`**
+
+- **作用**：验证字段是否符合有效的电子邮件格式。
+
+- **用法**：用于验证字符串字段是否为有效的电子邮件地址格式。
+
+- 示例
+
+  ```java
+  @Email(message = "请输入有效的电子邮件地址")
+  private String email;
+  ```
+
+### **`@Pattern(regexp)`**
+
+- **作用**：根据正则表达式验证字段值。
+
+- **用法**：可以根据自定义的正则表达式来验证字段的内容。
+
+- 示例
+
+  ```java
+  @Pattern(regexp = "^\\d{10}$", message = "请输入有效的手机号码")
+  private String phoneNumber;
+  ```
+
+### **`@Min(value)` 和 `@Max(value)`**
+
+- **作用**：确保数字类型字段的值在指定范围内。
+
+- **用法**：`@Min` 用于验证值是否大于等于指定的最小值，`@Max` 用于验证值是否小于等于指定的最大值。
+
+- 示例
+
+  ```java
+  @Min(value = 18, message = "年龄不能小于18岁")
+  @Max(value = 100, message = "年龄不能大于100岁")
+  private int age;
+  ```
+
+### **`@DecimalMin(value)` 和 `@DecimalMax(value)`**
+
+- **作用**：用于验证浮动值是否在指定范围内，类似于 `@Min` 和 `@Max`，但适用于 `BigDecimal` 或 `Double` 类型的数值。
+
+- **用法**：`@DecimalMin` 验证值是否大于等于指定的最小值，`@DecimalMax` 验证值是否小于等于指定的最大值。
+
+- 示例
+
+  ```java
+  @DecimalMin(value = "0.0", inclusive = true, message = "价格不能小于0")
+  private BigDecimal price;
+  ```
+
+### **`@Future`**
+
+- **作用**：验证日期字段的值是否为将来日期。
+
+- **用法**：用于 `java.util.Date`、`java.time.LocalDate` 或 `java.time.LocalDateTime` 等日期类型的字段。
+
+- 示例
+
+  ```java
+  @Future(message = "日期必须是未来的时间")
+  private LocalDate eventDate;
+  ```
+
+### **`@Past`**
+
+- **作用**：验证日期字段的值是否为过去的日期。
+
+- **用法**：类似于 `@Future`，但是验证日期必须是过去的时间。
+
+- 示例
+
+  ```java
+  @Past(message = "出生日期必须是过去的时间")
+  private LocalDate birthDate;
+  ```
+
+### **`@AssertTrue`**
+
+- **作用**：验证字段值是否为 `true`。
+
+- **用法**：适用于布尔类型字段，如果值不是 `true`，则验证失败。
+
+- 示例
+
+  ```java
+  @AssertTrue(message = "必须接受条款和条件")
+  private boolean acceptedTerms;
+  ```
+
+### **`@AssertFalse`**
+
+- **作用**：验证字段值是否为 `false`。
+
+- **用法**：适用于布尔类型字段，如果值不是 `false`，则验证失败。
+
+- 示例
+
+  ```java
+  @AssertFalse(message = "不能接受条款")
+  private boolean declinedTerms;
+  ```
+
+###  **`@Valid` 和 `@Validated`**
+
+- **作用**：触发嵌套对象的验证。
+
+- **用法**：当你有嵌套对象（如表单中的对象属性是另一个对象），使用 `@Valid` 或 `@Validated` 注解来递归验证该对象。
+
+- 示例
+
+  ```java
+  @Valid
+  private Address address;
+  ```
+
+### **`@Digits(integer, fraction)`**
+
+- **作用**：验证数字字段的有效性，确保字段值是一个有效的数字，并且整数部分和小数部分的位数符合指定要求。
+
+- **用法**：`integer` 参数用于指定数字的整数部分的最大位数，`fraction` 参数用于指定小数部分的最大位数。
+
+- 示例
+
+  ```java
+  @Digits(integer = 5, fraction = 2, message = "金额应为最大5位整数和2位小数")
+  private BigDecimal amount;
+  ```
+
+  - 这个例子验证金额字段的最大值为 `99999.99`（即最多5位整数和2位小数）。
+
+###  **`@CreditCardNumber`**
+
+- **作用**：验证信用卡号的有效性，确保其符合信用卡的常见格式，通常包括 Luhn 算法的验证。
+
+- **用法**：该注解用于验证信用卡号的格式是否有效。
+
+- 示例
+
+  ```java
+  @CreditCardNumber(message = "请输入有效的信用卡号")
+  private String creditCardNumber;
+  ```
+
+  - 该注解会根据常见的信用卡规则（如 VISA、MasterCard 等）验证输入的信用卡号是否合法。
+
+### **`@Range(min, max)`**（不是 Spring 内置的，但通常来自 Hibernate Validator）
+
+- **作用**：验证字段值是否在指定的范围内。常用于 `Integer`、`Long`、`Double` 等数值类型的字段。
+
+- **用法**：指定字段的有效范围，当值不在范围内时会验证失败。
+
+- 示例
+
+  ```java
+  @Range(min = 1, max = 100, message = "数字必须在1到100之间")
+  private int quantity;
+  ```
+
+  - 该注解会验证 `quantity` 字段的值是否在 `1` 到 `100` 之间。
+
+### **`@URL`**
+
+- **作用**：验证字段是否为有效的 URL 格式。
+
+- **用法**：用于字符串类型的字段，验证其是否符合有效的 URL 格式。
+
+- 示例
+
+  ```java
+  @URL(message = "请输入有效的网址")
+  private String website;
+  ```
+
+### **`@Valid` 与 `@Validated`**
+
+- **作用**：用于嵌套对象的验证，确保嵌套对象的字段也进行验证。
+
+- **用法**：这两个注解会触发嵌套对象的验证，通常用于嵌套的复杂表单数据结构。
+
+- 示例
+
+  ```java
+  @Valid
+  private Address address;
+  ```
+
+  - 如果 `Address` 类中有字段使用了验证注解，`@Valid` 会递归地验证 `Address` 对象的所有字段。
+
+### **`@FutureOrPresent`**
+
+- **作用**：验证日期或时间字段的值是否是当前日期（包括今天）或未来的日期。
+
+- **用法**：该注解用于日期和时间字段，确保其为今天或将来的日期。
+
+- 示例
+
+  ：
+
+  ```java
+  @FutureOrPresent(message = "事件日期必须是今天或将来")
+  private LocalDate eventDate;
+  ```
+
+### **`@PastOrPresent`**
+
+- **作用**：验证日期或时间字段的值是否是当前日期（包括今天）或过去的日期。
+
+- **用法**：与 `@FutureOrPresent` 相反，确保字段是过去或今天的日期。
+
+- 示
+
+  ```java
+  @PastOrPresent(message = "出生日期必须是过去的时间或今天")
+  private LocalDate birthDate;
+  ```
+
+### **`@Null`**
+
+- **作用**：验证字段是否为 `null`。如果字段不为空，则验证失败。
+
+- **用法**：该注解可以用于字段或方法参数上，确保字段值必须为 `null`。
+
+- 示例
+
+  ```java
+  @Null(message = "该字段必须为null")
+  private String nickname;
+  ```
+
+### **`@ScriptAssert(lang, script)`**
+
+- **作用**：通过自定义脚本验证字段值。
+
+- **用法**：允许使用自定义脚本（如 JavaScript）来执行复杂的验证逻辑。需要指定脚本语言和脚本内容。
+
+- 示例
+
+  ```java
+  @ScriptAssert(lang = "javascript", script = "_this.password == _this.confirmPassword", message = "密码和确认密码必须一致")
+  private String password;
+  private String confirmPassword;
+  ```
+
+  - 这个注解可以用于检查两个字段值是否一致。
+
+### **`@UniqueElements`**（Hibernate Validator 扩展）
+
+- **作用**：确保集合中的元素是唯一的，常用于 List 或 Set 类型字段。
+
+- **用法**：适用于集合类型字段，确保集合中的元素不重复。
+
+- 示例
+
+  ```java
+  @UniqueElements(message = "列表中的元素必须唯一")
+  private List<String> tags;
+  ```
