Test class private Members with Java Reflection (new)

http://my.oschina.net/wangyumin/blog/387627
The last reflection method calls the private member, and the method is recently encapsulated two times.

Reflectutil.java

    Partial code slightly/** * Invoking method Plus * * @param object Java Object * @param methodName methods Name * @param args Entry Object * @return Execution Result Object */public static object Invokemethodplus (Object object, String METHODN        Ame, Object ... args) {object result = NULL;            if (null! = args) {int length = Args.length;            class[] types = new Class[length];            Object[] values = new Object[length];                for (int i = 0; i < length; i++) {Types[i] = Args[i].getclass ();                Values[i] = args[i];                Original type fix field[] fields = Types[i].getfields ();  for (Field field:fields) {if ("TYPE". Equalsignorecase (Field.getname ())) {Try                        {Types[i] = (Class) field.get (null);                        } catch (Illegalaccessexception e) {logutil.error (e);   }                 }}} result = InvokeMethod (object, MethodName, types, values);    } return result; }

Comparison of new and old methods:

// 老方法:Object invokeMethod(Object object, String methodName, Class[] parameterTypes, Object[] args)

// 新方法(类型与入参不必分离由方法内部适配):Object invokeMethodPlus(Object object, String methodName, Object... args)

Reflectutiltest.java

    //部份代码略    @Test    public void testInvokeMethodPlusForInt() throws Exception {        int age = 18;        Person person = new Person();        String howOldAreYou = (String) ReflectUtil.invokeMethodPlus(person, "howOldAreYou", age);        Assert.assertEquals(Person.howOldAreYou + age, howOldAreYou);    }    @Test    public void testInvokeMethodPlusForString() throws Exception {        String name = "xuanyin";        Person person = new Person();        ReflectUtil.invokeMethodPlus(person, "setName", name);        String whatIsYourName = (String) ReflectUtil.invokeMethodPlus(person, "whatIsYourName");        Assert.assertEquals(Person.whatIsYourName + name, whatIsYourName);    }
