findAllBy*
目的 Purpose
Dynamic method that uses the properties of the domain class to create query method expressions that return all matching instances of the domain class
使用例 Examples
Given this domain class:
class Book { String title Date releaseDate String author Boolean paperback }
The following are all possible:
def results = Book.findAllByTitle("The Shining", [max: 10, sort: "title", order: "desc", offset: 100])results = Book.findAllByTitleAndAuthor("The Sum of All Fears", "Tom Clancy")
results = Book.findAllByReleaseDateBetween(firstDate, new Date())
results = Book.findAllByReleaseDateGreaterThanEquals(firstDate)
results = Book.findAllByTitleLike("%Hobbit%")
results = Book.findAllByTitleIlike("%Hobbit%") // ignore case
results = Book.findAllByTitleNotEqual("Harry Potter")
results = Book.findAllByReleaseDateIsNull()
results = Book.findAllByReleaseDateIsNotNull()
results = Book.findAllPaperbackByAuthor("Douglas Adams")
results = Book.findAllNotPaperbackByAuthor("Douglas Adams")
results = Book.findAllByAuthorInList(["Douglas Adams", "Hunter S. Thompson"])
詳細 Description
GORM supports the notion of Dynamic Finders. The findAllBy*
method finds all the results for the given method expression.

Pagination and sorting parameters can be used as the last argument to a dynamic method:
def results = Book.findAllByTitle("The Shining", [max: 10, sort: "title", order: "desc", offset: 100])
The following operator names can be used within the respective dynamic methods:
LessThan
LessThanEquals
GreaterThan
GreaterThanEquals
Between
Like
Ilike
(i.e. ignorecase like)IsNotNull
IsNull
Not
NotEqual
And
Or
InList
These operator names can be considered keywords, and you will run into problems when querying domain classes that have one of these names as property names. For more information on dynamic finders refer to the user guide.
