How to get property names of a pojo class without public no-arg constructor?

I want to get an array(or list) of a POJO's property names . I tried commons-beanutil's BeanUtils.describe(obj) , but it needs an object instance. But what if I only have that class , without a public no-arg constructor . I cannot use clazz.newInstance() to generate an object.

How should I solve it ? Is there any libraries that can dig into a class and pass property names ?

(I know I can use reflection to manually parse the class structure , but I am looking for a handy library)

Thanks.

Solution

  • I've never used it (or anything in java.beans, for that matter), but java.beans.Introspector.getBeanInfo(Class) may be what you're looking for.
