public ArgumentConvertingMethodInvoker()
方法详细资料
setTypeConverter
public void setTypeConverter(TypeConverter typeConverter)
Set a TypeConverter to use for argument type conversion.Default is a
SimpleTypeConverter. Can be overridden with any TypeConverter implementation, typically a pre-configured SimpleTypeConverter or a BeanWrapperImpl instance.
getTypeConverter
public TypeConverter getTypeConverter()
Return the TypeConverter used for argument type conversion.Can be cast to
PropertyEditorRegistryif direct access to the underlying PropertyEditors is desired (provided that the present TypeConverter actually implements the PropertyEditorRegistry interface).
getDefaultTypeConverter
protected TypeConverter getDefaultTypeConverter()
Obtain the default TypeConverter for this method invoker.Called if no explicit TypeConverter has been specified. The default implementation builds a
SimpleTypeConverter. Can be overridden in subclasses.
registerCustomEditor
public void registerCustomEditor(Class<?> requiredType, PropertyEditor propertyEditor)
Register the given custom property editor for all properties of the given type.Typically used in conjunction with the default
SimpleTypeConverter; will work with any TypeConverter that implements the PropertyEditorRegistry interface as well.- 参数:
requiredType- type of the propertypropertyEditor- editor to register- 另请参阅:
setTypeConverter(org.springframework.beans.TypeConverter),PropertyEditorRegistry.registerCustomEditor(java.lang.Class<?>, java.beans.PropertyEditor)
findMatchingMethod
protected Method findMatchingMethod()
This implementation looks for a method with matching parameter types.- 覆盖:
findMatchingMethod在类中MethodInvoker- 返回:
- a matching method, or
nullif none - 另请参阅:
doFindMatchingMethod(java.lang.Object[])
doFindMatchingMethod
protected Method doFindMatchingMethod(Object[] arguments)
Actually find a method with matching parameter type, i.e. where each argument value is assignable to the corresponding parameter type.- 参数:
arguments- the argument values to match against method parameters- 返回:
- a matching method, or
nullif none
