java - Spring @transactional doesn't work -

i'm using java configuration, work fine except @transactional, took me serval days try figure out, have no idea why doesn't work, great appreciate.

in usercontroller.java, try call userservice.testtransactional(user, request);

testtransaction() testing method in userserviceimpl, "long.valueof("throw runtimeexception");" line going throw exception in method, user added anyway, it's supposed roll back, user record persists

usercontroller.java

@controller public class usercontroller {      @resource(name="userservice")     protected userservice userservice;      @requestmapping(value = "/register", method = requestmethod.post)     public string processregister(model model, @modelattribute registerform registerform, httpservletrequest request) throws exception {          userservice.testtransactional(user, request);          return "account/register_success";     } } 

userserviceimpl.java

@service("userservice") public class userserviceimpl implements userservice {      @resource     private userdao userdao;      @transactional     public void testtransaction(user user, httpservletrequest request) throws exception {         long userid = userdao.add(user);         long.valueof("throw runtimeexception");     } } 

below configurations

web.xml

appconfig.java

@configuration  // specifies class configuration @enablewebmvc //enables use spring's annotations in code @componentscan(basepackages = {"com.myapp.account"}) // specifies package scan public class appconfig {     ... 

dataconfig.java

@configuration @enabletransactionmanagement public class dataconfig {      @bean(destroymethod="close")     public combopooleddatasource datasource() throws propertyvetoexception {         ...         return cpds;     }      @bean     public namedparameterjdbctemplate jdbctemplate() throws propertyvetoexception {         return new namedparameterjdbctemplate(datasource());     }      @bean     public datasourcetransactionmanager transactionmanager() throws propertyvetoexception {         datasourcetransactionmanager dstm = new datasourcetransactionmanager(datasource());         return dstm;     }       @bean     public userdao userdao() throws propertyvetoexception {         return new userdao(jdbctemplate());     } 

the problem haven't specified @enabletransactionmanagement on @configuration class component scanning , creating userserviceimpl bean. assuming class in com.myapp.account, configuration class component scans should have @enabletransactionmanagement. change dataconfig or appconfig appropriately.
