简单的invoke例子

public class TestMain {
	public static void main(String[] args) throws Exception {
		//泛型边界
		Class<? extends TwoArgs> clazz = new TwoArgs().getClass();
		Method [] methods= clazz.getDeclaredMethods();
		String methodName = methods[0].getName();
		//被调用方法的参数类型
		Method method = clazz.getMethod(methodName, new Class[] {String.class , String.class});
		System.out.println(method.invoke(new TwoArgs(), "1","111"));
		
	}
}

被调用的方法:

public class TwoArgs {
	public String twoArgsMethod(String str1, String str2){
		return (str1 == str2)? "OK!" : ("Str2 is : " + str2);
	}
}

如果是普通的JavaBean，获得方法参数还可以:

Method setMethod = mClassType.getMethod(setMethodName, new Class [] {fields[i].getType()});
