Db.propeties
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/indsu
username=root
password=root
dialect=org.hibernate.dialect.MySQLDialect
Properties form db.properties should be used not by Hibernate (with mergeProperties()), but it should be placed by Spring in place of this
<property name="hibernate.connection.driver_class">${driverClassName}</property>
A simply workaround just remove db.properties and hardcore properties form it in place of ${driverClassName} and others. And you don't need to use mergeProperties() anyway.
For an example
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

This seems like a strange issue to me. Even though it looks like the jdbcTemplate configured properly, jdbcTemplate.queryForObject fails with
o.a.tomcat.jdbc.pool.ConnectionPool : Unable to create initial connections of pool.
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ''#'localhost' to database
Right before queryForObject is called, I'm printing jdbcTemplate.getDataSource().toString(), which does show the username properly (like so:
...; url=jdbc:mysql://localhost/mydb; username=test; validationQuery=SELECT 1; ... ).
Code:
public class JdbcLookupDao implements UserDao, OrderDao {
private final JdbcTemplate jdbcTemplate;
public JdbcLookupDao(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
#Override
public User findUser(String phone) {
System.out.println(jdbcTemplate.getDataSource().toString());
return jdbcTemplate.queryForObject( //this line throws the exception
"SELECT * FROM users WHERE phonenumber = ?",
new Object[]{phone},
new UserMapper()
);
}
....
}
Spring config file:
...
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">

I hope someone can help me debug.
Thanks!
The problem was with permissions set in MySQL. The username used in the code didn't have access to the db.
I suppose the error message Access denied for ''#'localhost' is misleading -- it would've made sense if the actual username was shown instead of ''.
It looks like a DB access permission issue. you need to give the DB access permission for user in MYSQL Admin.
Your spring config has a missplaced double qoute
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${spring.datasource.driver-class-name}" />
<property name="url" value="${spring.datasource.url}"/>"
<property name="username" value="${spring.datasource.username}"/>
<property name="password" value="${spring.datasource.password}"/>
<property name="validationQuery" value="${spring.datasource.validation-query}"/>
</bean>
At the end of the 'url' property there is a extraneous ", remove that, and then spring will correctly pick up the username and inject it into the dataSource.
i.e.
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${spring.datasource.driver-class-name}" />
<property name="url" value="${spring.datasource.url}"/>
<property name="username" value="${spring.datasource.username}"/>
<property name="password" value="${spring.datasource.password}"/>
<property name="validationQuery" value="${spring.datasource.validation-query}"/>
</bean>
Check the Database defined in the properties exists on the MySql or check the url in properties file. This error comes when :-
Connection con = DriverManager.getConnection(url);
because at this point of time the connection to the database is getting created using the url which has username, password and database or schema(Oracle). So you need to check the url properly. Either some issue with the url or with the Database name if it exists on MySql server. It might be that you have changed your username on the Database and still using old username while connecting from the code.

Refer : #EnableTransactionManagement annotation with 2 transaction managers
#Transactional(value={METHOD,TYPE}) documentation for value states that
A qualifier value for the specified transaction.
May be used to determine the target transaction manager, matching the
qualifier value (or the bean name) of a specific
PlatformTransactionManager bean definition.
You need to add qualifier to point out which transaction manager to use.
Just change #Transactional() to #Transactional("transactionManager") or #Transactional("transactionManager1") whichever transaction Manager you want to use.

The problem was that the MySQL remote server binds to localhost by default. After commenting it and restart the server it worked.
I created basic wicket-spring-hibernate application. I think, that spring is integrated into wicket correctly.
When I start my application hibernate creates table from my model class, but when I try to open session from sessionFactory I get nullpointer exception.
I am using wicket version 6.5.0, spring version 3.2.1.RELEASE, hibernate version 4.1.9.Final
My home page:
public class HomePage extends WebPage {
private static final long serialVersionUID = 1332168213993623852L;
#Resource
RezervaceDao rezervaceDao;
public HomePage() {
add(new FormPanel("formPanel"));
Rezervace rezervace = new Rezervace("test1", "test2", "test3", "test4");
rezervaceDao.insert(rezervace);
}
}
my Dao class:
public class RezervaceDaoImpl implements RezervaceDao{
#Autowired
private SessionFactory sessionFactory;
#Override
#Transactional
public void insert(Rezervace rezervace) {
sessionFactory.getCurrentSession();
//sessionFactory.getCurrentSession().saveOrUpdate(rezervace);
}
}

Could you please try to help me?
Edit:
This is my WicketApplication.java
public class WicketApplication extends WebApplication
{
/**
* #see org.apache.wicket.Application#getHomePage()
*/
#Override
public Class<? extends WebPage> getHomePage()
{
return HomePage.class;
}
/**
* #see org.apache.wicket.Application#init()
*/
#Override
public void init()
{
super.init();
//getComponentInstantiationListeners().add(new SpringComponentInjector(this));
this.getComponentInstantiationListeners().add( new SpringComponentInjector( this) );
}
}
#Resource RezervaceDao rezervaceDao;
should be
#SpringBean RezervaceDao rezervaceDao;
Please excuse the possible improper formatting of this post as I have never posted here before. I have a Spring MVC web service running that calls into several DAO's that use JPA/hibernate to interact with a SQL Server database. The connection to the database seems to get closed after the web service has been running for a while.
An example of one of the DAO classes is the following:
#Repository
public class OceanClientDaoImpl {
// Create entity manager objects that will talk to the database
private EntityManagerFactory entityManagerFactory;
/**
* Load all clients in the database. Return as ClientLight objects.
*
* #return List of ClientLight objects.
*/
public List<Client> loadClients()
{
EntityManager entityManager = entityManagerFactory.createEntityManager();
entityManager.getTransaction().begin();
List<?> clients =
entityManager.createNativeQuery("select id, clientname, industry, logo, slug from client",
Client.class).getResultList();
entityManager.getTransaction().commit();
entityManager.close();
return Client.getCheckedList(clients);
}
}
The entityManagerFactory is injected via spring in the following way:
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value="url" />
<property name="username" value="user" />
<property name="password" value="pw" />
</bean>
<bean
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
id="entityManagerFactory">
<property name="dataSource" ref="dataSource" />
</bean>
<context:component-scan base-package="com.theocean.dao">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Repository" />
</context:component-scan>
<bean class="org.springframework.orm.jpa.JpaTransactionManager"
id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="oceanClientDaoImpl" class="com.theocean.dao.OceanClientDaoImpl">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
This all works fine when I first bring up the application. The application server is Tomcat. But, after the application is running for a while, requests to the server start receiving this error:
> SEVERE: Servlet.service() for servlet [spring] in context with path [/OceanWebService] threw exception [Request processing failed; nested exception is javax.persistence.PersistenceException: org.hibernate.TransactionException: JDBC begin failed: ] with root cause

So, the connection is being closed. Obviously something is wrong with the implementation whether it be the injection method or the method for handling errors, etc. So, the question is - What is the proper way to do this? How can I avoid the connection closed error? Thanks much in advance.
I think what could be happening is that some of the DAO's are leaving database transactions open when an error occurs.
The example DAO above is doing programmatic management of the database transaction, but does not handle the rollback scenario. This is an example of a DAO implementation that would do so:
MyService {
private EntityManagerFactory emf;
public void myMethod() {
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
MyDaoA myDaoA = new MyDaoA(em);
MyDaoB myDaoB = new MyDaoB(em);
try {
tx.begin();
myDaoA.doSomething();
myDaoB.doSomething();
tx.commit();
} catch(Exception e) {
tx.rollback();
}
}
}
All DAOs that do programmatic transaction management should use this pattern, otherwise sooner or later a transaction will not be rolled back and this could cause problems.
A much more frequent and less error prone way of implementing DAOs is to inject directly only an entity manager:
MyService {
#PersistenceContext
private EntityManager em;
#Autowired
private MyDaoA myDaoA;
#Autowired
private MyDaoB myDaoB;
#Transactional
public void myMethod() {
myDaoA.doSomething();
myDaoB.doSomething();
}
}
Injecting the EntityManagerFactory and doing manual transaction management should be reserved for exceptional cases, and the use of #Transactional be used by default.
I would say problem is with Connection pooling , so you can use c3p0 connection pooling library for fixing your problem, but you should be very carefull with connection pool properties.
Actually lot of ways you can do, I am giving you same code for reference. It might help.
Step 1: persistence.xml
<!-- c3p0 properties -->
<!-- Determines how many connections at a time c3p0 will try to acquire when the pool is exhausted -->
<property name="hibernate.c3p0.acquire_increment" value="1"/>
<!-- If this is a number greater than 0,
c3p0 will test all idle, pooled but unchecked-out connections, every this number of seconds -->
<property name="hibernate.c3p0.idle_test_period" value="60"/>
<property name="hibernate.c3p0.max_size" value="20"/>
<property name="hibernate.c3p0.max_statements" value="50"/>
<property name="hibernate.c3p0.min_size" value="5"/>
<property name="hibernate.connection.provider_class" value="org.hibernate.connection.C3P0ConnectionProvider" />
Step 2: And then we create c3p0.properties under src/main/resources/META-INF with following properties
c3p0.testConnectionOnCheckout=true
c3p0.preferredTestQuery=SELECT 1;
Step 3: You need to configure data source
<bean id="myJdbcDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<!-- Connection properties -->
<property name="driverClass" value="$DS{database.class}" />
<property name="jdbcUrl" value="$DS{database.url}" />
<property name="user" value="$DS{database.username}" />
<property name="password" value="$DS{database.password}" />
<bean/>
