Debugging "Injection of autowired dependencies failed" Error in Spring+Hibernate - java

I have just started with Spring Framework and trying to develop and run a simple a app using Spring + Hibernate + Maven for dependency management.
I have a ContactController in which a property of type ContactService is Autowired. But when i packaged it into war and deployed on tomcat it throws a org.springframework.beans.factory.BeanCreationException with following messages :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'sessionFactory' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]:
Invocation of init method failed; nested exception is org.hibernate.MappingException:
An AnnotationConfiguration instance is required to use <mapping
class="org.kodeplay.contact.form.Contact"/>
So I commented out that property from the ContactController Class along with all its references and re deployed it. But still it shows the same error.
This is the only controller in the entire application and an object implementing the ContactService interface is not being used any where else.
Whats going on here ? Am I missing something ?
Edit : Adding the code for spring-servlet.xml

I suspect this be a clash between AnnotationSessionFactoryBean and hibernate.cfg.xml. If you're using the former, you shouldn't need the latter. If you use both, you're going to have to duplicate some settings, and the cfg file might be eclipsing the Spring config.
Whatever you have in hibernate.cfg.xml you should be able to move into the bean definition for the AnnotationSessionFactoryBean, and that should resolve your error.

I guess you try to configure Hibernate with org.springframework.orm.hibernate3.LocalSessionFactoryBean. However, you use annotations in Hibernate mapping, therefore you need to use org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean instead.

Any help would be great! thanks
Your component scan needs to be as below,
<context:component-scan base-package="com.domain.nameOfapp" />
This will scan all the classes under this package including any sub-packages.
Also using #ManagedProperty, are you trying to autowire the spring service bean? I believe you should be using #Autowired.

Access property values inside Spring config file

I have a simple properties file at WEB-INF/local.db.properties:
db.driverClassName=org.postgresql.Driver
db.url=jdbc:postgresql://localhost:5432/db_name
db.username=postgres
db.password=password
I am trying to access these properties inside of my Spring configuration file (towards the end):

<property name="password" value="${db.password}" />
</bean>
</beans>
The error is Could not load JDBC driver class [${db.driverClassName}]. The error is pretty clear to me - it is not trying to look up the property it is just using the raw string.
How do I fix this?
This is a Maven 3, Spring 4, Postgresql project.
You're not loading the properties file in Spring configuration. Add this line:
<context:property-placeholder location="classpath:/WEB-INF/local.db.properties"/>
or
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="/WEB-INF/local.db.properties"/>
</bean>
If you have several properties file, change the above configuration for:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<!-- locations, not location, check the S at the end -->
<property name="locations">
<list>
<value>
/WEB-INF/local.db.properties
</value>
<value>
<!-- Path of another properties file -->
</value>
</list>
</property>
</bean>
More info: PropertySourcesPlaceholderConfigurer
If you are using Eclipse, try right click on project -> Properties -> Java Build Path -> Source, then Add Folder or Link Source to your property files.

Issue
As of now in hibernate.cfg.xml, I have mentioned hibernate.connection.autocommit = true and in daoimpl while saving entity I need to call flush after .save .
If I remove hibernate.connection.autocommit = true and .flush from daoimpl class, I observed that .save method in daoimpl is not working, means my data is not inserting and even I cannot see insert query executed by hibernate on console.
hibernate.connection.autocommit = true should not be there in hibernate cfg xml as if I doing operation on multiple table in same transaction and if some error occurred then rollback will not happen.
I want that .save in daoimpl should work even I don't write hibernate.connection.autocommit = true in hibernate cfg xml and .flush.
I am using #Transactional annotation for transaction.
You haven't added any TransactionManager to your configuration:
Remove the following properties:
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.autocommit">true</property>
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">20</property>
<property name="hibernate.c3p0.timeout">300</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.idle_test_period">3000</property>
Add a connection pooling DataSource (DBCP2 is a much better alternative than C3P0)
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" oracle.jdbc.driver.OracleDriver"/>
<property name="url" value="your-oracle-driver-url"/>
<property name="username" value="your-username"/>
<property name="password" value="your-password"/>
</bean>
Now add the Sessionfactory Spring proxy:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
Add the TransactionManager bean
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>
Update
If you have the transaction manager set in a separate spring application context (e.g. root-context.xml), then move these lines from your web context to where the back-end context:
<tx:annotation-driven transaction-manager="transactionManager"/>
<context:component-scan base-package="com.abc.service" />
<context:component-scan base-package="com.abc.dao" />
And only allow the web context to scan its own beans:
<context:component-scan base-package="com.abc.web" />
It's not good to mix the web and the back-end contexts responsibilities.
My problem solved, I just wrote the annotation #Transactional in the
#Repository
#Transactional
public class AbstractHibernateDao<T extends Serializable> {
private Class<T> clazz;
#Autowired
private SessionFactory sessionFactory;
And that solved that I couldnt Delete or Save without using Flush.

How do I configure dynamic weaving using EclipseLink & Spring?

How do I configure dynamic weaving using EclipseLink & Spring? Right now I'm trying to get this working with a Junit test, but I'll later have to have it work with Tomcat (my department has been standardized on it for something like 10 years).
I'm running into two main problems:
1. Spring wants a load time weaver:
Exception:

I can fix this by configuring the Spring Instrumentation:
JVM parameter:
-javaagent:/path/to/org.springframework.instrument-3.1.0.M2.jar
2. Eclipselink is not satisfied with the Spring Instrumentation:

I tried to fix this by using the EclipseLink weaver:

But then I get the same exception from problem #1.

For weaving with Spring I believe you need something like,
<bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
<property name="defaultDataSource" ref="dataSource" />
<property name="dataSources">
<map>
<entry>
<key>
<value>jdbc/__default</value>
</key>
<ref bean="dataSource" />
</entry>
<entry>
<key>
<value>jdbc/jta</value>
</key>
<ref bean="dataSource" />
</entry>
</map>
</property>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
</property>
</bean>
There is some information here,
http://wiki.eclipse.org/EclipseLink/Examples/JPA/JPASpring
Ensure you are not accessing your classes before accessing the Spring context.
Another solution is to use static weaving.
Now, I am also using EclipseLink 2.2 and Spring 3.1 as below. My configuration is a little different with yours.
There is no loadTimeWeaver configuration in your eclipseLinkEntityManagerFactory. I think, it will be ok if you use as below.
Please, try as below with your Oracle DB information..

copy org.springframework.instrument-3.1.0.M2.jar into tomcat/lib directory and try it again.
Considering the instrumentation for unit tests, one can add it as VM argument to the maven-surefire-plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>-javaagent:lib/test/spring-instrument-4.0.2.RELEASE.jar</argLine>
</configuration>
</plugin>
assuming spring-instrument jar was placed at corresponding location.
(For that, the following dependency could be added temporarily to the project pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-instrument</artifactId>
<scope>test</scope>
</dependency>
and then after the build, the corresponding artifact copied from local .m2 directory to project's lib/test directory.)

loading .properties in spring-context.xml and persistence.xml

is there a way to reference a .properties file in a spring-context.xml and a JPA persistence.xml?
I think I've seen somewhere an example of this in spring context files, though I can't remember where that was. Maybe someone knows this?
About the persistence.xml I am actually unsure if this works at all.
My aim is to change some properties between development and distribution configuration.
The idea I have currently is to replace all properties manually in the files via ant from a template config. Though there should be a better way to do this. :)
Rather than using your build to create a prod or dev version of your persistence.xml, just move all property settings
to your spring content.
My persistence.xml is
<?xml version="1.0" encoding="UTF-8"?>
<persistence
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="JPAService" transaction-type="RESOURCE_LOCAL">
</persistence-unit>
</persistence>
In my spring content, i then use the PropertyPlaceholderConfigurer to read dev/prod property values and set these into the
entityManagerFactory bean
<?xml version="1.0" encoding="UTF-8"?>

You can reference external property files from a Spring bean definition file using a PropertyPlaceholderConfigurer. I don't think that will work for a JPA persistence.xml, although Spring's JPA support allows you to incorporate most, if not all, the content of persistence.xml into the beans file itself, in which case it would work fine.
