方法详细资料

setTypeConverter

public void setTypeConverter(@Nullable
                             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.

SimpleTypeConverter, BeanWrapperImpl

getTypeConverter

@Nullable
public TypeConverter getTypeConverter()

Return the TypeConverter used for argument type conversion.

Can be cast to PropertyEditorRegistry if 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 property

propertyEditor - editor to register

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 org.springframework.util.MethodInvoker

另请参阅:

doFindMatchingMethod(java.lang.Object[])

doFindMatchingMethod

@Nullable
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 null if none
