Set properties with method names as keys and transaction attribute descriptors as values.
The various transaction attribute descriptors are parsed via an instance of the TransactionAttributeEditor class.
Note Method names are always applied to the target class, no matter if defined in an interface or the class itself.
Internally, a NameMatchTransactionAttributeSource will be created from the given properties.
An example string (method name and transaction attributes) might be:
key = "myMethod", value = "PROPAGATION_REQUIRED,readOnly".
