Method Details

where

public static Criteria where(String key)

Static factory method to create a Criteria using the provided key

Parameters:

key - the property or field name.

Returns:

new instance of Criteria.

byExample

public static Criteria byExample(Object example)

Static factory method to create a Criteria matching an example object.

Parameters:

example - must not be null.

Returns:

new instance of Criteria.

Since:

1.8

See Also:

• alike(Example)

byExample

public static Criteria byExample(Example<?> example)

Static factory method to create a Criteria matching an example object.
By default the Example uses typed matching restricting it to probe assignable types. For example, when sticking with the default type key (_class), the query has restrictions such as _class : { $in : [com.acme.Person] } .
To avoid the above mentioned type restriction use an UntypedExampleMatcher with Example.of(Object, org.springframework.data.domain.ExampleMatcher).

Parameters:

example - must not be null.

Returns:

new instance of Criteria.

Since:

1.8
