I have a spring batch application that uses Azure SQL server as a backend, I am using Hibernate to update the database.
Below is my Hibernate configuration
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager" lazy-init="true">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="hibernateProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="properties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2012Dialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">false</prop>
<!-- <prop key="hibernate.hbm2ddl.auto">update</prop> -->
</props>
</property>
</bean>
<bean class="org.springframework.batch.core.scope.StepScope" />
<!-- DATA SOURCE -->
<bean id="demoDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value="jdbc:sqlserver://demo.database.windows.net:1433;database=sqldb;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;" />
<property name="username" value="user1" />
<property name="password" value="p#ssword1" />
</bean>
I want know all the list of queries and its average execution time, how do I achieve this?
You can check p6spy. This tool wraps your datasource and logs all queries along with their execution time.

I have a Java Batch Program which is triggered from a BPEL process used for inserting set of Record into DB.
Size of record might vary but at an average around 20,000 to 40,000.
My custom java batch picks up the data from an excel uploaded from a third party app into server location.
For performing the DML operation I have gone with Hibernate/Spring JDBC framework.
Refer to my spring configuration file as below::
<context:component-scan base-package="mybasepackage" />

I am already using c3p0 for ConnectionPooling and also visited the following links:

But still I am getting following exception::

I'm working with Hibernate. How can I configure my applicationContext.xml to have an H2 in-memory databaseorg.hibernate.dialect.H2Dialect dont work

You are not connecting to an in-memory database. Your JDBC URL is for network connection to localhost:
jdbc:h2:tcp://localhost/~/test
To use the in-memory H2 the URL must look like this, containing mem:
jdbc:h2:mem:testdb
In the manual, see the section on In-Memory Database
Use embedded db datasource (with dbcp connection pool) instead of drivermanager datasource.
<jdbc:embedded-database id="dataSource" type="H2">
<jdbc:script location="classpath:db/sql/create-db.sql" />
<jdbc:script location="classpath:db/sql/insert-data.sql" />

I am using a configuration in my spring-hibernate application. The configuration is given below. My Question is, what the purposes & duties of, DataSource, sessionFactory, Transaction Manager and JPA Template here. And why one bean id is used in another one.
<!-- DataSource -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}"/>

<!-- Transaction Manager-->

I remix Spring Data and Hibernate in my Application to access MS-SQL Data.
In My All Service class,I set #Transactional(readOnly=true) in front of the class name.Recently,I observe some DB Table Locks occurrence.
Otherwise,I set#Transactional(readOnly=true,isolation = Isolation.READ_UNCOMMITTED) to avoid DB Table lock,but it throws
org.springframework.transaction.InvalidIsolationLevelException: Standard JPA does not support custom isolation levels - use a special JpaDialect for your JPA implementation.
How can I modify the XML to use isolation = Isolation.READ_UNCOMMITTED for dirty read?

I have Spring MVC application divided on layers. One of them is Service and here's one of the methods
#Transactional
public boolean deleteProject(long id){
Project project = projectDAO.read(id);
taskDAO.deleteAllByProject(project);
projectDAO.delete(project);
return true;
}
It deletes tasks, but project remains in the db (with no error or exception). I didnt use #Transactional in repository classes.
Here's my Spring config
<?xml version="1.0" encoding="UTF-8"?>
<bean id="validator"
class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
<bean id="myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="url" value="jdbc:postgresql://localhost:5432/automate" />
<property name="username" value="postgres" />
<property name="password" value="" />
</bean>
<bean id="mySessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<property name="packagesToScan" value="ru.jeak.keep" />
<property name="hibernateProperties">

<bean id="projectHibernateDAO" class="ru.jeak.keep.repository.hibernate.ProjectHibernateDAO" />
<bean id="taskHibernateDAO" class="ru.jeak.keep.repository.hibernate.TaskHibernateDAO" />
UPDATE
I added persistence #Transactional to DAO class and it works now. But Im still confused why Spring did not do the rollback of deleting tasks after failure of deleting project
