public class ReflectivePropertyOperator
extends Object
implements PropertyOperator

Implementation of PropertyOperator based on Java reflection.
Supports reading and writing JavaBean properties via Field or getter/setter methods.

supports:

This property operator can be used to handle the following scenarios:

• The property actually exists, and there is a corresponding getter or setter method: the getter/setter method is preferred to complete the reading and writing of the property value;
• The property actually exists, but there is no corresponding getter or setter method: directly use Field to complete the reading and writing of the property value;
• The property does not actually exist, but there are getter or setter methods that conform to the specification: use the getter/setter method to complete the reading and writing of the property value;

throws exception:

If the specified property cannot find a Field or getter/setter method that supports read and write, the operation will be aborted and null (if there is a return value) will be returned.
We can set throwIfNoAnyMatched to true to throw an exception in this case.

type conversion:

Setting ConverterManager, the class supports a certain degree of automatic conversion of parameter types when writing property values.
