public ConstructorExecutor resolve(EvaluationContext context,
                                              String typeName,
                                              List<org.springframework.core.convert.TypeDescriptor> argumentTypes)
                                       throws AccessException

Locate a constructor on the type. There are three kinds of match that might occur:

1. An exact match where the types of the arguments match the types of the constructor
2. An in-exact match where the types we are looking for are subtypes of those defined on the constructor
3. A match where we are able to convert the arguments into those expected by the constructor, according to the registered type converter.

指定者:

resolve 在接口中 ConstructorResolver

参数:

context - the current evaluation context

typeName - the type upon which to look for the constructor

argumentTypes - the arguments that the constructor must be able to handle

返回:

a ConstructorExecutor that can invoke the constructor, or null if non found

抛出:

AccessException
