property (key) can not found setter method

The error message "property (key) cannot find setter method" typically occurs when you're trying to set a value for a property (key), but there is no corresponding setter method defined for that property.

To resolve this issue, you need to make sure that you have defined a setter method for the property (key) in your code. The setter method should have the same name as the property, but with the prefix "set" followed by the property name in camel case.

For example, if your property is named "key", the setter method should be defined as:

public void setKey(String key) {
    this.key = key;
}

Make sure to adjust the data type and access modifier according to your specific needs. Once you have correctly defined the setter method, you should be able to set the value for the property without encountering the error.
