java - PropertyPlaceholderConfigurers loading after parameterized DataSource bean -

-

at top of application context declare propertyplaceholderconfigurer

... <context:annotation-config/>  <context:property-placeholder location="classpath:foo.properties"/> ...

later on declare datasource bean parameterized properties properties file

<bean id="somedatasource" class="oracle.jdbc.pool.oracledatasource" destroy-method="close">     <property name="connectioncachingenabled" value="true"/>     <property name="url" value="${database.url}"/>     <property name="user" value="${database.user}"/>     <property name="password" value="${database.password}"/> </bean>

during deployment notice datasource bean created , connection attempted established before propertyplaceholderconfigurer initialized. that's causing datasource parameterizations not populated.

any idea why might happening?

is there specific order of creation beans? beans initialized before others? there way ensure propertyplaceholderconfigurer loaded before other beans?

it turns out 1 of beans defined mapperscannerconfigurer mybatis references sqlsessionfactory.

the mapperscannerconfigurer can initialize prior propertyplaceholderconfigurer if it's initialized deprecated bean properties

to correct behavior, sqlsessionfactory has referenced using different bean property.

see this related post more details

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
