JAvaの反射使用

シーン:javaの反射使用、比較的良いフレームワークを開発する際に必要な道1.java反射

public class ReflectUtils {

	/**      */
	public static Object doReflectWork(final String ClassName,final String methodName, final Object[] obj) {
		try {
			Class cls = Class.forName(ClassName);
			Method method = null;
			for (Method method1 : cls.getMethods()) {
				if (method1.getName().equals(methodName)) {
					method = method1;
				}
			}
			if (method != null) {
				int modifers = method.getModifiers();
				/**             ,         */
				if (Modifier.isStatic(modifers)) {
					method.invoke(cls, obj);
					/**             */
				} else {
					method.invoke(cls.newInstance(), obj);
				}
				return "    ";
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}
}

2.テスト例

public class TestReflect {
	
	public static void  doworkCity(String obj1,String obj2){
 	System.out.println("    1: " + obj1.toString() );
 	System.out.println("    2: " + obj2.toString() );
	}	
	public void  doworkProvince(String obj){
		System.out.println("    : " + obj.toString());
	}
	//com.zbz.test.TestReflect
	public static void main(String [] args){	
		Object[] objStatic = new Object[]{"      !","    2"};
		System.out.println("    ......");
		System.out.println("      :");
		ReflectUtils.doReflectWork("com.zbz.test.TestReflect", "doworkCity", objStatic);
		System.out.println("       :");
		Object[] obj2 = new Object[]{"       !"};
		ReflectUtils.doReflectWork("com.zbz.test.TestReflect", "doworkProvince", obj2);
		System.out.println("    ......");
	}
}

以上、TKS.
