[English Version](README.en.md)

## EST SPI 反射模块

est-spi-reflection 是 EST SPI 框架的反射模块，提供了反射工具、类扫描器和方法调用器。

### 核心功能

#### ReflectionUtils - 反射工具类
提供各种反射操作的工具类，包括实例化、方法调用、字段访问等。

#### ClassScanner - 类扫描器
扫描指定包下的所有类，支持文件系统和JAR包。

#### MethodInvoker - 方法调用器
带缓存功能的方法调用器，支持实例方法和静态方法调用。

### 快速开始

#### 使用ReflectionUtils实例化对是?

```java
import ltd.idcu.est.spi.reflection.ReflectionUtils;

public class Example {
    public static void main(String[] args) {
        MyClass instance = ReflectionUtils.newInstance(MyClass.class);
        System.out.println("Instance created: " + instance);
        
        MyClass instanceWithArgs = ReflectionUtils.newInstance(MyClass.class, "param1", 123);
        System.out.println("Instance with args created: " + instanceWithArgs);
    }
}
```

#### 使用ReflectionUtils调用方法

```java
import ltd.idcu.est.spi.reflection.ReflectionUtils;

public class Example {
    public static void main(String[] args) {
        MyClass instance = new MyClass();
        
        Object result = ReflectionUtils.invokeMethod(instance, "publicMethod");
        System.out.println("Result: " + result);
        
        Object resultWithParams = ReflectionUtils.invokeMethod(instance, "methodWithParams", "hello", 456);
        System.out.println("Result with params: " + resultWithParams);
    }
}
```

#### 使用ReflectionUtils访问字段

```java
import ltd.idcu.est.spi.reflection.ReflectionUtils;

public class Example {
    public static void main(String[] args) {
        MyClass instance = new MyClass();
        
        Object value = ReflectionUtils.getFieldValue(instance, "privateField");
        System.out.println("Field value: " + value);
        
        ReflectionUtils.setFieldValue(instance, "privateField", "newValue");
        Object newValue = ReflectionUtils.getFieldValue(instance, "privateField");
        System.out.println("New field value: " + newValue);
    }
}
```

#### 使用ClassScanner扫描是?

```java
import ltd.idcu.est.spi.reflection.ClassScanner;

import java.util.List;

public class Example {
    public static void main(String[] args) {
        List<Class<?>> allClasses = ClassScanner.scan("com.example.package");
        System.out.println("Found classes: " + allClasses.size());
        
        List<Class<? extends MyInterface>> implementations = 
            ClassScanner.scan("com.example.package", MyInterface.class);
        System.out.println("Found implementations: " + implementations.size());
    }
}
```

#### 使用MethodInvoker调用方法

```java
import ltd.idcu.est.spi.reflection.MethodInvoker;

public class Example {
    public static void main(String[] args) {
        MyClass instance = new MyClass();
        
        Object result = MethodInvoker.invoke(instance, "publicMethod");
        System.out.println("Result: " + result);
        
        Object staticResult = MethodInvoker.invokeStatic(MyClass.class, "staticMethod");
        System.out.println("Static result: " + staticResult);
        
        System.out.println("Cache size: " + MethodInvoker.getCacheSize());
        MethodInvoker.clearCache();
    }
}
```
