Transaction does not work Closing non transactional sqlsession

in proxy mode (which was the default), only external method calls coming in through the proxy is intercepted. This means is self-invocation, in effect, a method within the target object calling another method of the target object, Would not leads to a actual transaction at runtime even if the invoked method was marked with @Transactional .

Spring Document Address:

http://docs.spring.io/spring/docs/4.2.0.RC1/spring-framework-reference/htmlsingle/#transaction-declarative-annotations

Description: In proxy mode, only external method calls are intercepted and transactions are opened. Class internal calls cannot implement transaction control.

Error Example:

 Public class Tx {        publicvoid  A () {        B ();    }         = propagation.required)    publicvoid  B () {            }}

Correct example:

 Public class Tx {        = propagation.required)    publicvoid  A () {        B ();    }              Public void B () {            }}
