高级应用:通过反射获得泛型的参数…

import java.lang.reflect.Method;

import java.lang.reflect.ParameterizedType;

import java.lang.reflect.Type;

import java.util.Vector;

public class GenericTest {

public static voidgetGenericParameterType(Vector<String>vector) {

}

public static void main(String[] args) throws Exception{

//通过反射获得泛型参数的实际类型

Method method =GenericTest.class.getMethod("getGenericParameterType",

Vector.class);

Type[] types =method.getGenericParameterTypes();

ParameterizedType type =(ParameterizedType)types[0];

System.out.println(type.getRawType());

System.out.println(type.getActualTypeArguments()[0]);

}
