type erasure，就没法得到它的class，比如我想用List.class，就会报错，
但是有些class method只接受这样的input argument:
public void foo(Class class)
如果我想传入一个List的类的话，怎么办？没法用
foo(List.class) |

发帖数: 4809 | 3 多谢，如果是第三方库没有办法改method呢？比如这个：
public static JAXBContext newInstance(Class... classesToBeBound)
我没法传入List.class

发帖数: 46 | 6 There is a solution,
create a generic list wrapper to wrap your String List, whatever List, and
JAXB always unmarshall xml message to the wrapper, and from this wrapper
object, you can get the wrapped List object.
I have used this approach a lot in my projects, it works well.

发帖数: 4809 | 7 Thanks. This is a nice solution. I think it is similar to goodbug's solution
but it uses a generic List in the wrapper class.
