Class DataBindingMethodResolver

java.lang.Object
org.springframework.expression.spel.support.ReflectiveMethodResolver
org.springframework.expression.spel.support.DataBindingMethodResolver
All Implemented Interfaces:
MethodResolver

public final 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.

Since:
4.3.15

      @Nullable public MethodExecutor resolve(EvaluationContext context, Object targetObject, String name, List<TypeDescriptor> argumentTypes) throws AccessException
      Description copied from class: 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
      Specified by:
      resolve in interface MethodResolver
      Overrides:
      resolve in class ReflectiveMethodResolver
      Parameters:
      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
      Returns:
      a MethodExecutor that can invoke the method, or null if the method cannot be found
      Throws:
      AccessException
    • isCandidateForInvocation

      protected boolean isCandidateForInvocation(Method method, Class<?> targetClass)
      Description copied from class: 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 and non-user-declared methods on the Object base class.

      Overrides:
      isCandidateForInvocation in class ReflectiveMethodResolver
      Parameters:
      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.
