I have three xml files in my spring hibernate app
Spring-Security.xml
<security:authentication-manager>
<security:authentication-provider user-service-ref="customUserDetailsService">
</security:authentication-provider>
</security:authentication-manager>
<!-- Use a Md5 encoder since the user's passwords are stored as Md5 in the database -->
<bean class="org.springframework.security.authentication.encoding.Md5PasswordEncoder" id="passwordEncoder"/>
<!-- A custom service where Spring will retrieve users and their corresponding access levels -->
<bean id="customUserDetailsService" class="com.vaannila.service.CustomUserDetailsService" >
</bean>
hibernate-context.xml
enter code here
<!-- Declare a datasource that has pooling capabilities-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close"
p:driverClass="${app.jdbc.driverClassName}"
p:jdbcUrl="${app.jdbc.url}"
p:user="${app.jdbc.username}"
p:password="${app.jdbc.password}"
p:acquireIncrement="5"
p:idleConnectionTestPeriod="60"
p:maxPoolSize="100"
p:maxStatements="50"
p:minPoolSize="10" />
<!-- Declare a transaction manager-->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory" />
<bean id="registrationDAO" class="com.vaannila.dao.RegistrationDAOimpl" >
<constructor-arg ref="sessionFactory"/>
</bean>
Now in my spring security i want something like
<bean id="customUserDetailsService" class="com.vaannila.service.CustomUserDetailsService" >
<constructor-arg ref="registrationDAO"/>
</bean
but my registrationDAO is in hibernate-config and when i do that in spring Security it says no bean named registration DAO
Spring supports reading application context across external jars. Simply add "classpath:" prefix to the context file name. Spring will look for it in the whole project.
For instance, if you are creating web application, you might declare your business logic application context like this (web.xml)
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml <!-- tell Spring to look for context defined on the classpath -->
</param-value>
</context-param>
That way You'll be able to use as many context, as necessary.

I am implementing spring security in an existing spring mvc project. I had used xml to configure the spring security. I have used this tutorial for implementing spring security
http://www.mkyong.com/spring-security/spring-security-form-login-using-database/
In my project I have a db-source file(MySQL_Datasource.xml) in resources folder just under main (outside of webapp). And the way spring security is implemented in tutorial, the datasource needs to be under webapp folder. I am facing this problem of integration.
Below is the snap of my project structure and on the right side config. code of web.xml, I have commented on the line in image where i have to define my dataSource location.
This is code of spring security where dataSource will be used

I am doing this first time. I need help so that I can get this done.
UPDATE:
MYSQL_DataSource.xml code:
<bean id="dataSource" class= "org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>db.properties</value>
</property>
</bean>
and below is the db.properties values:
jdbc.url = jdbc:mysql://localhost/bhaiyag_prod_grocery
jdbc.username = newuser
jdbc.password = kmsg
If your project is correctly configured, src/main/resources folder will be packaged during project build under WEB-INF/classes.
So, if maven configuration or deployment-assembly section in project/properties is Ok, the path that you should use in your web.xml is like this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/groceryapp-servlet.xml
/WEB-INF/spring-security.xml
/WEB-INF/classes/MySQL_DataSource.xml
</param-value>
</context-param>
It should work this way.
Once it works, have a look at this question and answers spring-scheduler-is-executing-twice and this one too web-application-context-root-application-context-and-transaction-manager-setup. In many of the Mkyong's tutorials the application context is loading twice, and I'm pretty sure it would happen the same with your project once it starts working.
As your groceryapp-servlet.xml is already loaded by Spring MVC's dispatcher servlet, you could try just removing it from contextConfigLocation setting, just this way:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring-security.xml
/WEB-INF/classes/MySQL_DataSource.xml
</param-value>
</context-param>
Properties loading problem:
To load correctly the db.properties, try this config in DB config xml:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:/db.properties</value>
</property>
</bean>
You can also specify context location relatively to current classpath. Make sure the resources folder is on your classpath and if it is. Then you can load the configuration file in your resources folder like,
<context-param>
<param-value>classpath:MySQL_DataSource.xml</param-value>
</context-param>
I have a spring-hibernate feature built as a separate jar (Collection.jar) for use by multiple webapps. This collection.jar has a spring-config.xml where beans are defined. When this jar is included in a webapp (spring-application1), the classes defined in collection.jar are not getting auto-wired.
spring-config.xml from Collection.jar
<context:annotation-config/>
<context:component-scan base-package="com.antk.pkg" />
<import resource="spring-datasource.xml" />
<bean id="delegator" class="com.antk.pkg.Delegator">
<property name="dbUtils" ref="dbUtils" />
</bean>
<bean id="dbUtils" class="com.antk.pkg.util.DBUtils">
<property name="dao" ref="collectorDao" />
</bean>
<bean id="collector" class="com.antk.pkg.Collector">
<property name="collectorService" ref="collectorServiceImpl" />
</bean>
<bean id="collectorServiceImpl" class="com.antk.pkg.service.CollectorService">
<property name="collectorDao" ref="collectorDaoImpl" />
<property name="delegator" ref="delegator" />
</bean>
...
and in spring-application1, I am including the above as :
<bean id="com.antk.pkg.collector.spring"
class="org.springframework.context.support.ClassPathXmlApplicationContext" abstract="false"
scope="prototype" lazy-init="default" autowire="default">
<constructor-arg>
<list>
<value>spring-config.xml</value>
</list>
</constructor-arg>
</bean>
But when I call collector, collectorservice is being set as null all the time. Its not getting autowired. Any thoughts.
Assuming your spring-config.xml to be present in your classpath.
Put below in your web.xml -
1) Specify which spring config files to load
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring-config.xml</param-value>
</context-param>
2) Define the ContextLoaderListener :-
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Also there is a problem while loading spring-config.xml files from jar.
" Resource implementation supports resolution as java.io.File if the class path resource resides in the file system, but not for classpath resources which reside in a jar and have not been expanded (by the servlet engine, or whatever the environment is) to the filesystem." http://docs.spring.io/spring/docs/current/spring-framework-reference/html/resources.html
Avoid relying on classpath resource loader while loading config.xml files from jar.
Well, very likely there isn't any mystery but I am just not smart enough to figure out what my problem is. However usually it is the mystery after all!
Sorry for the introduction, my problem is that the prototype scope doesn't seem to work for me. I have created a REST service with a Spring Integration flow (there is a http inbound gateway in the front of the flow). The scopes of most of the beans are prototype. I tested the flow by calling it ten times with threads. Also I logged the bean references (just print the 'this' in the object being called) and I saw the same reference ten times!
e.g. org.protneut.server.common.utils.XmlToMapConverter#755d7bc2
To my knowledge it means that no new instance is being created for the XmlToMapConverter but using the same instance ten times. Am I right?
Very likely I configured the Spring incorrectly but I just cannot find out what I missed.

So I defined the scope of XmlToMapConverter is prototype but still I can't have new object at a new request. The situation is the same for convertRestToWorkflowBean which is the first service call in the flow (service-activator).
Could you please explain to me where the problem is?
Thanks, V.
I don't see xmlToMapConverter usage, but I see this:
<int:service-activator
input-channel="fromConvertToActivator-channel"
output-channel="toCallChain-channel"
id="convertRestToWorkflowBean-serviceActivator"
ref="convertRestToWorkflowBean" method="convert">
where you use this:
<bean id="convertRestToWorkflowBean" class="org.protneut.server.rest.ConvertRestMessageToWorkflowBean" scope="prototype"/>
The issue you are facing is called scope impendance. That's because <int:service-activator> populates several singleton beans, hence the reference to your prototype becomes as singleton, too.
One way to overcome that to use SpEL from there:
<int:service-activator
input-channel="fromConvertToActivator-channel"
output-channel="toCallChain-channel"
id="convertRestToWorkflowBean-serviceActivator"
expression="#convertRestToWorkflowBean.convert(payload)"/>
In this case your convertRestToWorkflowBean is retrieved from the BeanFactory on each call.
Another trick to go ahead looks like:
<bean id="convertRestToWorkflowBean" class="org.protneut.server.rest.ConvertRestMessageToWorkflowBean" scope="prototype">
<aop:scoped-proxy/>
</bean>
In this case your bean will be wrapped to the ScopedProxyFactoryBean and all invocation will be delegated to your prototype on demand.
Prototype scoped beans will be created every time you call ApplicationContext.getBean(...)
You've included the bean definition but haven't shown how other services reference it. My guess is it's injected into a singleton service once during initialization hence there's only one. Perhaps you need to call ApplicationContext.getBean() each time to get a new instance.
There are other solutions involving dynamic proxies that ultimately invoke getBean(), I'm on my mobile at the moment so too hard to find a link for you.
I've got a strange problem which I think is Spring related. I'm developing a Maven multi module application structured as follow:
DataModule (includes generale Hibernate entities and daos)
ServiceModule (includes specific Hibernate entities and daos) - depends on DataModule
Web (gwt web module) - depends on ServiceModule
In DataModule I've a classic Spring-Hibernate xml configuration, consisting of (relevant code):
ApplicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans ..>
<!-- Auto scan the components -->
<context:annotation-config />
<context:component-scan base-package="com.x.dataModule" >
<context:include-filter type="regex"
expression="com.x.dataModule.dao.*" />
</context:component-scan>
<!-- Import resources -->
<import resource="applicationContext-hibernate.xml" />
<import resource="applicationContext-dataSource.xml" />
</beans>
applicationContext-hibernate.xml
<beans ..>
<bean id="defaultLobHandler" class="org.springframework.jdbc.support.lob.DefaultLobHandler" />
<!-- Hibernate session factory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean ">
<property name="packagesToScan" value="com.x.dataModel.model.**.*"></property>
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="lobHandler" ref="defaultLobHandler" />
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.query.substitutions">true 1, false 0</prop>
<prop key="hibernate.connection.useUnicode">true</prop>
<prop key="hibernate.connection.charSet">UTF8</prop>
</props>
</property>
</bean>
<!-- Transaction Manager -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="persistenceExceptionTranslationPostProcessor"
class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
</beans>
Hibernate.cfg is actually empty, since I aim to avoid explicit mapping due the use of packagesToScan property. applicationContext-dataSource is not relevant since it contains ds configuration.
The ServiceModule relies on the previous module.
applicationContext.xml
<beans ...>
<!-- Auto scan the components -->
<context:include-filter type="regex"
expression="com.x.serviceModule.dao.*" />
<context:include-filter type="regex"
expression="com.x.serviceModule.manager.*" />
<!-- Import resources -->
<context:property-override location="classpath:override.properties"/>
<import resource="classpath*:/applicationContext-hibernate.xml" />
<import resource="classpath*:/applicationContext-dataSource.xml" />
</beans>
The file override.properties contains the following entry, to modify the definition of packagesToScan
sessionFactory.packagesToScan=com.x.*.model.**.*
At this point everything works just fine. The serviceManagers (singletons) are loaded from the factory as
ApplicationContext appContext = new ClassPathXmlApplicationContext(
"applicationContext.xml").getBean(..);
And everything is behaving as expected.
Last part, the Web Module. If I import the ServiceModule and test it as a Java application, again everything is fine. However, if I start the module as a web application, it fails complaining that it's not able to load entities/daos defined in the DataModule.
Relevant files in Web Module:
WEB-INF/spring
applicationContext.xml: nothing here other than the import of applicationContext-security.xml (residing in the same directory)
web.xml
<!-- Spring context -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/spring/applicationContext.xml
</param-value>
</context-param>
<!-- Creates the Spring Container -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
</listener>
The only way to avoid the problem is to declare explicitly the entities mapping and daos definition in the DataModule xml files.
My question: is there a way to avoid such declarations, and rely entirely on the component/package scan also in Web Module?
I'm not really sure but looks like that somehow the spring web context is conflicting with my other spring context. Otherwise, I don't understand why everything is fine as Java application, but fails as web.
Also (not sure if relevant) it seems that the Session Factory bean is istantiated twice during the process (shouldn't it be a singleton?).
Spring version is 3.1.1 Release, Hibernate 3.6.0 Final (4.0.1 for commons-annotations). Tomcat 7 for deploy.
I didn't provide the Java code of entities/daos/managers since I don't think it's relevant for the question; however, I can provide it if it's of any help. Thanks a lot
I read this "It is a best practice to keep a clear separation between middle-tier services such as business logic components and data access classes (that are typically defined in the ApplicationContext) and web- related components such as controllers and view resolvers (that are defined in the WebApplicationContext per Dispatcher Servlet)."
And decide configure my application like that 4 separate xml file

But I'm absolutly confused.
1)I don't understand how many context in this case I get.
2)I want easy replace tx mode on aspectj (which work just in ome context as I know). But when I replace I get error with transation.
Main problem that I want to have universal variant for both type of transaction
Here I add mode="aspectj" and I have annotation like #Service, #Resourse, on concrete classes
<tx:annotation-driven transaction-manager="transactionManager" mode="aspectj" proxy-target-class="true"/>

Please, help me uderstand better
convention is you have one root context, normally applicationContext.xml. Then different servlet contexts (for different modules/functionality)... myapp-servlet.xml.
The servlet context can see everything in root context, but not the other way. Controllers and webby stuff(static resources) go in servlet context, everything else (eg service, and security) go in root context.
You can import different files as you please. But define those two contexts in your web.xml (or Java conf equivalent).
I still do it the old fashioned xml way, you don't have to use java conf.
Whats your actual error ?
