following the answer given in this question, I have removed the spring-webmvc.jar file from my lib to avoid a repetition with the one in the core project. However, when I do this, it seems that the #Autowired for at least a bean does not work any more.
The class having the #Autowired is the following (in which none of the field is filled):
public class SecurityUserCheckBeforeControllerHandler implements BeforeControllerHandler
{
#Resource(name = "userService")
private UserService userService;
#Autowired
private CMSPageContextService cmsPageContextService;
#Override
public boolean beforeController(final HttpServletRequest request, final HttpServletResponse response,
final HandlerMethod handler) throws IOException
{
// Code where the autowired fields are used (-> produces null pointer)
}
}
The spring configuration can be summarized as follows:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>
If I follow the advise given in most of the similar questions (i.e. adding an #Component above the class that would be scanned), the bean will be created twice:
with the list given in the config file:
The autowired fields will be null which will still give a NullPointerException when the bean in the list is used
by the component-scan:
The fields are correctly autowired but the bean is not used in the list.
Strangely, if I put back the spring-webmvc.jar previously removed because of this question, the #Autowired will work as expected.
Trying to compare the stacktraces between the two configurations, I saw that the beans are created at different moments in the class org.springframework.context.support.AbstractApplicationContext during the startup of the server.
Last point: there is no error during the compilation and the startup of the server.
Do you have any idea for a solution please?
Thank you for reading me,
Laurent

Is there anyway to get beans loaded via <context:component-scan/> in a xml file to be proxy'ed by an #Coniguration annotated class which has #EnableCaching and declares the SimpleCacheManager? This would be the easiest route for the large applicaiton I'm working with, my ultimate preference would be to convert it all over to a Configuration class, but that is a lot more work and there are next to no unit tests for this application -.- , something would totally break. The other option is to declare the Cache's in the xml which works fine but I feel like is a step backwards.
NOTE: The <context:annotation-config/> is declared in a separate xml file 'integration.xml' I put it back in the applicationContext.xml but it didn't affect anything.
The declaration of the caches and the enabling of the caching via #EnableCaching was moved to the below java class some time ago and I don't think anyone noticed that it stopped working. So I would like to get it working again in the best way.

Answer provided by chalimartines
When I access a bean from spring bean configuration file using BeanFactory like this:
public class Person {
private String id,address;
#Autowired
private Customer customer;
//setters & getters
}
and bean configuration file
<bean name="person" class="com.ram.spring.model.Person"></bean>
<bean class="com.ram.spring.model.Customer">
<property name="email" value="ram#adp.com"></property>
<property name="name" value="Ram"></property>
</bean>
here is the executor class
public class PersonExecutor {
public static void main(String[] args) {
BeanFactory context = new XmlBeanFactory(new ClassPathResource("Spring.xml"));
Person person = (Person)context.getBean("person");
System.out.println(person.getCustomer());
}
}
when I execute this, I got null.is BeanFactory not supported for annotations?? any ideas??
Approach 1: Include below code in your xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<!-- Remaining bean declaration -->
</beans>
Approach 2: Remove #Autowired and inject customer in your xml file only.
<bean name="person" class="com.ram.spring.model.Person">
<property name="customer" ref="customer"></property>
</bean>
<bean name="customer" class="com.ram.spring.model.Customer">
<property name="email" value="ram#adp.com"></property>
<property name="name" value="Ram"></property>
</bean>
You have to use AnnotationConfigApplicationContext or
you have to add to yor Spring.xml to activate the annotation scan.
As #jens suggested
you should active annotation scan
<context:component-scan base-package="package_path">
</context:component-scan>
<context:annotation-config />
hope that helped
Why doesn't it work?
When using Spring with an XML context, using annotations is not activated by default. This means #Autowired, #Transactional, #PostConstruct and any other annotation you will use will simply not be exploited.
How do I fix it?
To make Spring aware of annotations, you need to add the following line:
<context:annotation-config />
Thus, Spring will search for annotations in the beans it creates and process them accordingly.
This requires activating the context namespace. At the top of your context, make sure you have all context related links and arguments1:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<!-- Your context -->
</beans>
You do not need <context:component-scan /> in your case. This would be useful if you used full-annotation context (e.g. classes annotated with #Component). See the difference between <context:annotation-config /> and <context:component-scan /> in this answer.
Alternate solution
As Naman Gala suggested, you could also drop #Autowired completely and inject all dependencies in XML. See the related answer for more details.
1 This includes the xmlns:context attribute (xmlns = XML NameSpace) and two URLs in xsi:schemaLocation.
I'm still new to spring and I'm trying to get ehcache spring annotations setup correctly. I'm using Spring 3.2.3 ehCache 2.4 and ehcache-spring-annotations-1.2.
When I try to access the reference to the cacheManager, it is always null. All the jars are on the build path, ehcache.xml is in the classpath and there are no xml errors. I've tried also including the classes in the component scan and using #Resource instead of Autowired. I'm stuck!
Application context:
<?xml version="1.0" encoding="UTF-8"?>

<!-- ehCache Annotation settings -->
<ehcache:annotation-driven cache-manager="ehCacheManager" />
<bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache.xml" />
<property name="shared" value="true"/>
</bean>
Wrapper
#Component
public final class MyCache implements Serializable {
#Autowired
private CacheManager ehCacheManager;
private getCacheManager() {
return ehCacheManger; // this is always null
}...}
It seems you are trying to use the EhCacheManagerFactoryBean as your cache manager.
Looking at Spring caching documentation, you need to declare another bean to be your CacheManager created from the factory.
I have a web application which has more than 40 Mbean. I used Spring Framework.
I am doing good and its working well. But i have 40 Mbean, so want to generalize the thing.
#Component
#ManagedResource(objectName="ProjectCache:name=XMBean", log=true, logFile="jmx.log")
public class XMBean extends AbstractCacheMBean<String, XCO, XCache> {
#ManagedOperation(description ="ProjectCache XCO key")
#Override
public List<String> showAllKeys(){
return super.getKey();
}
#ManagedOperation(description ="ProjectCache XCO")
public List<String> showAllElements(){
return super.findAll();
}
#Override
public XCache getCache() {
return getFacadeCache().getXCache();
}
#ManagedOperation(description ="ProjectCache XCO by key)
#Override
public String ShowbyKey(String key) {
return super.findbyKey(key);
}
}
Now i have Same way Class YMbean, AMBean and so.
I configured the Spring in application mbean.xml.

And same way i am going to preapre YMbean Class and in xml going to initialise.
What should i do that not require modification in XML Whatsoever or number of class i create ,dont require to update XML.
property is same in all Mbean which i am going to use.
All ideas or input are welcome.
Thanks
Remove all of your configuration and replace with the use of the namespace and only once. Also your MBeans are #Components so you can simply scan for them. Which only would leave you with the following lines of xml
<context:component-scan base-package="in.projet.business.mbean" />
<context:mbean-export/>
Or if you want to keep your current configuration instead of the namespace replace it at least with the following and remove all other beans. This enables autodetection of MBeans in your application context (this is basically the same as the <context:mbean-export /> does.
For more information I strongly suggest the JMX chapter of the reference guide.
I'm trying to test a service with Mockito and testNG, but i have a couple of doubts. It's necessary create get/set to inject service, if service is declaredd like this:
#Autowired(required = true)
protected ITipService serveiTip;
when I'm trying to clean and package with maven I found this exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'consultaDeutes' defined in URL
[file:/D:/workspaceGPT/GPT/gpt.ui/target/test-classes/applicationContext-gui-deutes-Test.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'serveiTip' of bean class [cat.base.gpt.ui.ConsultaDeutesTest]: Bean property 'serveiTip' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
I believe that with autowiring get/set will be not necessary.

Using #Autowired will make spring automatically inject a matching bean into that field. Thus it is no longer required to define the "consultaDeutes" bean in the xml. If you'd like to use the xml definition, I believe you should define a setter for each property that you are trying to inject, eg: serveiTip, serveiGpt.
Using #Autowired in your test might require 2 additional annotation on the definition of your test class:
#ContextConfiguration(value = "/myContext.xml")
//#RunWith(SpringJUnit4ClassRunner.class) This is JUnit specific
#ActiveProfiles("dev")
public class TestCompareService {
#Autowired(required = true)
protected ITipService serveiTip;
....
}
I actually made a mistake pasting the #RunWith annotation specific for JUnit. For TestNG you can lookup this link. Apologies
