Any help will be appreciated!!!
Use
<property name="destination" ref="SMMessageQueue"/>
instead of destinationName.
Spring can resolve a destination from its name but since you have the destination, you should inject that directly.

The stack trace is telling you enough. I have the same problems and solved it by renaming "datasource" to "dataSource". That thing is case sensitive so be careful. Hope that helps.

The Excpetion is:
Context initialization failed: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springSessionJdbcOperations' defined in class path resource [org/springframework/session/jdbc/config/annotation/web/http/JdbcHttpSessionConfiguration.class]: Unsatisfied dependency expressed through method 'springSessionJdbcOperations' parameter 0: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: datas1,datas2; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: datas1,jndi2.
I can not have two datasources configured, The first datasource is to the entityManagar and second datasource is to call stored procedure.
The JdbcSessionConfiguration expects a bean of type 'DataSource' with name 'dataSource'.
If this cannot be found, spring tries to use a bean of type 'DataSource', ignoring the name. Because there are two beans of this type, the exception is thrown.
Solution :
Rename the DataSource bean, that you want to use with the EntityManager from
'datas1' to 'dataSource'.
Spring should than be able to create JdbcSessionConfiguration and you can use the 'datas2' for whatever you need.
I use springmvc to build my project. But I have a problem:

Did you read exception fully? It is very detailed:

Change this line:

to this:

I am getting this exception when initializing BasicDataSource. I want to pass Custom connection property to the dataSource.
My config is:

Does the parameter type of the setter match the return type of the getter?

I used this post from spring forum to resolve the issue.
Adding this bean solved my issue.

but when i comment out #Repository annotation on EmployeeDaoImpl or if I comment out PersistenceExceptionTranslationPostProcessor bean declaration, then the applicationContext loads properly.
<!-- <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> -->
or
//#Repository
public class EmployeeDaoImpl implements EmployeeDao{
...........
}
I would like to know why this is happening. Could anyone please explain me this.
Type of HibWorker.employeeDaoImpl is EmployeeDaoImpl, therefore exception translation proxy of type HibernateDao can't be assigned to it.
Generally it's a bad practise to restrict implementation of dependencies this way, you should use interface (EmployeeDao) when declaring dependencies instead. If you follow that way, you also don't need proxy-target-class = "true" on <tx:annotation-driven>.
Alternative solution is to enable target class proxying for PersistenceExceptionTranslationPostProcessor.
