Good day all.
Writting JUnit test for my Spring app meet with the next problem.
My standart Context Configuration files storage on the project in /webapp (that don't part of classpath for Unit test).

It looks like application context is loaded correctly but you have to indicate that test class uses web configuration:
#WebAppConfiguration
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(
locations = {"file:src/main/webapp/WEB-INF/config/mvc-config.xml",
"file:src/main/webapp/WEB-INF/config/application-context.xml"})

Currently I'm trying to setup Spring MVC Controller testing for a school project I'm working on next to my job. Normally I program in php and frameworks like Laravel so this is pretty new for me. The problem is that I can't figure out how to solve the problem that keeps popping up on loading the ApplicationContext. Any help is appreciated.
Update:
I'm now told that test cases don't use a jndi ref in my app server. So this reference would fail on a test case, it runs fine on starting the application. Now I made a second file called servlet-test.xml (listed below) that uses a reference to the database on port 3306. I only use this file on tests not when starting up the application. But when I use this method I get Following error: Error creating bean with name 'productController': Injection of autowired dependencies failed. Any help is welcome as I'm struggling to setup MVC Controller tests for my school project. Other students I've been working with also are stuck with the same problem I am so I could help them out too.
I suspect the problem is the following, but I'm not sure how to solve this.

According to your stack trace when application context is initializing it still try to load wrong configuration files (servlet.xml), but should load servlet-test.xml. Please try to change your config locations with using path from root (src) folder, such as:
#ContextConfiguration({"file:src/main/web/WEB-INF/servlet-test.xml", "file:src/main/web/WEB-INF/dispatcher-servlet.xml"})
P.S Also you can try to move your config for tests (servlet-test.xml) to src/test/resources and load it from classpath: "classpath:servlet-test.xml". Also you can check this thread on stackoverflow: Spring #ContextConfiguration how to put the right location for the xml for extended discussion of similar problem.
You get an error which says that Spring IOC container fails to create and instantiate entityManagerFactory bean. Why?
That's another thing that your error exception mention. It fails to do so because it can't instantiate the myDataSource bean. Why?
According to your error message:
Lookup failed for 'java:app/fotoproducent'
It means that when IOC Spring container tried to create myDataSource bean, it failed to do so because it failed to set the jndiName with value of java:app/fotoproducent
Instead of using this:
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean" scope="singleton">
<property name="jndiName" value="java:app/fotoproducent" />
<property name="resourceRef" value="true" />
</bean>
Replace it with:
<bean id="myDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="your_driver_class_name" />
<property name="url" value="url_to_your_db" />
<property name="username" value="user_name_to_db" />
<property name="password" value="password_to_db" />
</bean>
My suggestion is to create a standard dataSource like mentioned on Spring docs above.
Now don't forget to replace the values for driver class name, url, user name, and password.
Here is an example from Spring docs, of how to define a data source for use of Hibernate ORM: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#orm-hibernate

public class LoginServiceImpl implements LoginService{

public boolean checkLoginDetails(LoginDetails loginDetails) {

}
}
Problem: My LoginDAO is null. Spring is not able to instantiate it's object using auto-wiring when done without annotation, however, works fine when I use it with annotation along with appropriate changes in ApplicationContext.xml.
My LoginService bean is getting instantiated by the component scan of dispatcher servlet context. Now when instantiating LoginServiceImpl spring should look into RootApplication context for other bean definitions however it doesn't.
I don't understand why does this happen when using #autowire with or enabling the component scan. it works fine then why not without annotation.
I'm also not sure what I'm trying to do. I was playing with Spring MVC and got stuck on this.
Please update your ApplicationContext.xml
<bean id="loginService" class="org.app.DAOServiceImpl.LoginServiceImpl" autowire="byName">
<property name="loginDAO" ref="loginDAO"> </property>
</bean>
Same thing goes for the EmployeeService and your controller as well.
<bean class="org.app.controller.HomeController" autowire="byName">
<property name="loginService" ref="loginService"> </property>
</bean>
<bean id="employeeService" class="org.app.DAOServiceImpl.EmployeeDAOServiceImpl" autowire="byName">
<property name="employeeDAO" ref="employeeDAO"> </property>
</bean>
Though I still recommend you to use annotations.
In AppplicationContext.xml you need to specify injected dependencies for your beans as element inside

Searching similar questions on web,I thought it occurs due to lack of some hibernate dependencies and added them.But it didn't work.Now, I am out of ideas!
My project is here: https://github.com/fsel/Spring-Hibernate-JSF-MySQL-Eclipse-Integration/tree/master/Spring-Hibernate-JSF-MySQL-Example
Any help would be appreciated.
Thanks!
The Person Class is loaded twice.
In Spring configuration - applicationContext.xml file you have :
<property name="mappingResources">
<list>
<value>domain-classes.hbm.xml</value>
</list>
</property>
Also in hibernate configuration - hibernate.cfg.xml file you are loading it once again:
<mapping resource="domain-classes.hbm.xml"/>
To fix the issue, just remove one of the above entries, either from Spring configuration file or Hibernate configuration file.

if you closely observe both files you are duplicating hibernate mapping resource
In hibernate.cfg.xml
<mapping resource="domain-classes.hbm.xml"/>
In a applicatinContext.xml
<property name="mappingResources">
<list>
<value>domain-classes.hbm.xml</value>
</list>
</property>
solution:
removing mappingResources property from applicatinContext.xml file should resolve you problem
thank you
You do not have a constructor without arguments in Person.
Hibernate, and code in general that creates objects via reflection use
Class.newInstance() to create a new instance of your classes. This
method requires a public no-arg constructor to be able to
instantiate the object. For most use cases, providing a no-arg
constructor is not a problem.

Why does Hibernate require no argument constructor?

Most likely you have lambda expression inside one of your spring beans. Apparently, spring 3 beans can't initialize if there is a lambda somewhere in their code. In case migration to spring 4 is not an option, try to rewrite your lambda expressions using anonymous classes, like
Function<A,B> lambda = new Function() {
public B apply(A s) { ... }
}
or move lambda code out of the spring bean. I had the same issue and it helped me, I could still use spring 3 with jre/jdk 8.
Avoids this failure:
Caused by: java.lang.ArrayIndexOutOfBoundsException: 10348
at org.springframework.asm.ClassReader.<init>(Unknown Source)
You have not stated which JDK you are using. If you are using 1.8 then you might find that you will need to upgrade Spring to 4 (or 3.2.9+ as yurez has pointed out).
See the answer to this question:
Java 1.8 ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet
The problem is the location of your xml file. WEB-INF is not part of the classpath. Try copying it under the "src" folder.
Try putting the file under src folder. It will be then copied to the WEB-INF/classes folder. Then you can refer to it as classpath:dispatcher-servlet.xml.
If the file is not directly under the classes directory, then you cannot use the location as classpath:dispatcher-servlet.xml in your test
There seems to be some invalid class file on your classpath.
A blog(http://blog.163.com/mxl_880310/blog/static/1847222162012320102631220/) (in Traditional Chinese) describes a similar problem, the author solves it by checking if there is a zero size class file.
I am attempting to split out the Hibernate DAO and Model Object layer from an existing application so they can be used across multiple applications. Unfortunately, I'm not having much success: a NoSuchBeanDefinitionException is thrown when trying to get the SessionFactory from the Application Context.
All of DAO classes extend a class called GenericDaoHibernate2. Each DAO extends this, and passes a Class in the constructor. Pretty standard Generic DAO stuff.
I figured this would be the logical place to set the session factory as well (there are ALOT of DAO classes). So, in the constructor class, I did this:
public GenericDaoHibernate2(final Class<T> persistentClass) {
ctx = new ClassPathXmlApplicationContext("META-INF/applicationContext-dao.xml");
this.sessionFactory = (SessionFactory) ctx.getBean(SessionFactory.class);
log.debug("Value of app context: " + ctx.toString());
log.debug("Value of sessionFactory: " + sessionFactory);
this.persistentClass = persistentClass;
}
Unfortunately, this blew up with the previously mentioned exception:
Caused By: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

Truncated. see log file for complete stacktrace
I've also attempted this with the app context file just in the classpath, setting the value when declaring the variable, etc, etc.
I'm guessing what is happing is that as part of the Maven build, the jar isn't referencing the libraries on the classpath, but I really don't know...
UPDATE: Stupid, stupid me... forgot to show the application context file.

Another update: Was asked for a sample DAO. The interface is a "standard" generic interface, accepting the generic paramters T and PK, just like the Impl. The following one doesn't have any specific methods other than what it inherits from GenericDaoHibernate2.
#Repository("AreaOfPreferenceDAO")
public class HibernateAreaOfPreferenceDAO extends GenericDaoHibernate2<AreaOfPreference, AreaOfPreferenceCompositeId> implements AreaOfPreferenceDAO {
public HibernateAreaOfPreferenceDAO()
{
super(AreaOfPreference.class);
}
}
In order to wire in the SessionFactory into your custom generic DAO, you can go ahead and simply use #Autowire, as long as the overall Spring context is defining the SessionFactory bean.
To define the bean:
<bean id="sessionFactory" class=
"org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="org.rest" />
<property name="hibernateProperties">
...
</property>
</bean>
<bean id="dataSource" class=
"org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${driverClassName}" />
<property name="url" value="${url}" />
<property name="username" value="restUser" />
<property name="password" value="restmy5ql" />
</bean>
And to wire, simply:
#Autowired
SessionFactory sessionFactory;
The right place to bootstrap the context is not in the constructor of your DAO; if you're working with a web application, you can go with the traditional approach:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/dispatcher-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Since this is not a web application, then the context cannot be bootstrapped in web.xml; however, the bootstrapping still needs to be external - a main class would simply need to create the XmlWebApplicationContext and configure it.
Hope this helps.
The fact that you are creating a new application context in each DAO object may be getting you into trouble.
ctx = new ClassPathXmlApplicationContext("META-INF/applicationContext-dao.xml");
This is kind of circular if you think about it. You call the context, which does a component scan for DAO's, then the DAO instantiates a new context, which does a component scan for DAO's ...
I would just autowire the sessionfactory directly as someone else had mentioned.
#Repository("AreaOfPreferenceDAO")
public class HibernateAreaOfPreferenceDAO extends GenericDaoHibernate2<AreaOfPreference, AreaOfPreferenceCompositeId> implements AreaOfPreferenceDAO {
#Autowired
public HibernateAreaOfPreferenceDAO(SessionFactory sessionFactory)
{
super(sessionFactory, AreaOfPreference.class);
}
}
No component should need to construct a new application context.
Had the same problem, unable to make injection work.
My problem was "sequence". Hibernate xml must be invoked first.
