SneakyThrows 是 Java 8 中的一个注解,用于在方法中抛出受检查异常而不需要在方法声明中声明该异常。它的作用是避免因为方法抛出异常而导致代码中出现过多的 try-catch 语句,从而使代码更加简洁易懂。使用 SneakyThrows 注解需要引入 lombok 库。需要注意的是,虽然使用 SneakyThrows 注解可以省略掉方法声明中的异常抛出,但是方法抛出的异常依然会被抛出,所以在调用该方法时需要仍然需要进行异常处理。

@SneakyThrows
@SneakyThrows是Lombok提供的一个注解,用于简化处理异常的代码。使用这个注解后,在编译时会自动将注解替换为try-catch块,从而消除了手动处理异常的模板代码。 通过使用@SneakyThrows注解,我们可以在方法中抛出异常,而无需显式地在方法签名中声明异常,从而使代码更加简洁。当使用@SneakyThrows注解时,编译器会自动生成实际的异常处理代码,确保异常被捕获并正确处理。因此,@SneakyThrows注解能够提高代码的可读性和可维护性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

lombook SneakyThrows
Lombok's `@SneakyThrows` annotation is used to suppress checked exceptions without explicitly declaring them in the method signature. It allows you to throw checked exceptions without adding them to the method signature or handling them with a try-catch block.
By adding `@SneakyThrows` to a method, Lombok automatically wraps any checked exception thrown within that method and rethrows it as a runtime exception. This simplifies the code and avoids the need for unnecessary try-catch blocks.
Here's an example of how to use `@SneakyThrows`:
```java
import lombok.SneakyThrows;
public class Example {
@SneakyThrows
public void doSomething() {
// code that throws a checked exception
}
}
```
In this example, if the code inside the `doSomething` method throws a checked exception, it will be wrapped in a `RuntimeException` and propagated without requiring the method to declare or handle the exception explicitly.
