所有已实现的接口:

MethodResolver

public class DataBindingMethodResolver
extends ReflectiveMethodResolver

A MethodResolver variant for data binding purposes, using reflection to access instance methods on a given target object.

This accessor does not resolve static methods and also no technical methods on java.lang.Object or java.lang.Class. For unrestricted resolution, choose ReflectiveMethodResolver instead.

从以下版本开始:

4.3.15

static DataBindingMethodResolver	forInstanceMethodInvocation() Create a new data-binding method resolver for instance method resolution.
protected boolean	isCandidateForInvocation(Method method, Class<?> targetClass) Determine whether the given Method is a candidate for method resolution on an instance of the given target class.

resolve

@Nullable
public MethodExecutor resolve(EvaluationContext context,
                                         Object targetObject,
                                         String name,
                                         List<org.springframework.core.convert.TypeDescriptor> argumentTypes)
                                  throws AccessException

从类复制的说明: ReflectiveMethodResolver

Locate a method on a 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 MethodResolver

覆盖:

resolve 在类中 ReflectiveMethodResolver

参数:

context - the current evaluation context

targetObject - the object upon which the method is being called

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

返回:

a MethodExecutor that can invoke the method, or null if the method cannot be found

抛出:

AccessException

isCandidateForInvocation

protected boolean isCandidateForInvocation(Method method,
                                           Class<?> targetClass)

从类复制的说明: ReflectiveMethodResolver

Determine whether the given Method is a candidate for method resolution on an instance of the given target class.

The default implementation considers any method as a candidate, even for static methods sand non-user-declared methods on the Object base class.

覆盖:

isCandidateForInvocation 在类中 ReflectiveMethodResolver

参数:

method - the Method to evaluate

targetClass - the concrete target class that is being introspected

forInstanceMethodInvocation

public static DataBindingMethodResolver forInstanceMethodInvocation()

Create a new data-binding method resolver for instance method resolution.
