Spring How to inject value to Queue by XML

Using Spring Framework, I want to create a bean object of type Person, and this bean object have a queue property of type Queue<Integer>, how to inject value to the property through XML?
The spring version is 4.3
The reference document is https://docs.spring.io/spring/docs/4.3.25.RELEASE/spring-framework-reference/htmlsingle/#beans-factory-class-ctor
but I can't find queue.
I try to use <bean> element, but the property queue of the bean is empty.
The Object is as follow
public class People {
private int id;
private Queue<Integer> queue;
// add constructor
// add get and set
}
The applicationContext.xml is as follow
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="..." class="...">
<property name="queue">
<bean class="java.util.ArrayDeque">
//How should I add values to the queue object
</bean>
</property>
</bean>
</beans>

By referring to Spring support on collection, the List, Set and Map interface can be injected by <list/>, <set/> and <map/> elements. The Queue interface is not supported. However, since ArrayDeque has a constructor for Collection, we can inject values from a List to ArrayDeque through <constructor-arg/> elements.
The following example demonstrates how to add value to the ArrayDeque.
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="people" class="spring.People">
<property name="queue">
<bean class="java.util.ArrayDeque">
<constructor-arg>
<list value-type="java.lang.Integer">
<value>1</value>
<value>2</value>
<value>3</value>
</list>
</constructor-arg>
</bean>
</property>
</bean>
</beans>
Main Class
package spring;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class InjectQueueApplication {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
People people = context.getBean("people", People.class);
System.out.println(people.getQueue().toString());
}
}

Spring Caching proxy not applying to beans loaded in xml vs those loaded in #Configuration

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.

why #autowired is not working when I access a bean

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.

Mbean JMX Spring Framework

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.

</bean>
<bean id="xMBean"

<property name="memoryCache" ref="repository" />
</bean>
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.

Native CXF integration in grails

Does somebody know how to integrate the cxf framework without using the cxf plugin? I have already published a simple service, but my problem is to inject existing grails service bean in the cxf jaxws bean.
In applicationContext.xml i'm using following definition
<jaxws:server id="jaxwsService" serviceClass="at.pdts.cxf.HelloWorld" address="/hello">
<jaxws:serviceBean>
<bean class="at.pdts.cxf.HelloWorldImpl">
<property name="halloService"><ref bean="helloWorld"></ref></property>
</bean>
</jaxws:serviceBean>
</jaxws:server>
The helloWorld bean is a normal grails serivce class. During startup i get following exception.
Cannot resolve reference to bean 'helloWorld' while setting bean
property 'halloService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'helloWorld' is defined

HelloWorldImpl.groovy
package at.pdts.cxf
import javax.jws.WebService

public class HelloWorldImpl implements HelloWorld {
def halloService // inject HelloService. Initialize this bean via applicationContext.xml
public String sayHi(String text) {
return "hello " + halloService.scream(text)
}
}
HelloService.groovy
class HalloService implements InitializingBean{
static transactional = false
String scream(String text) {
text.toUpperCase()
}
// methods gets not called, so service bean is not initialized at the ws creation time
void afterPropertiesSet() {
println "------> initializing bean HalloSerivce <--------
}
}
It seems that at the moment of the jaxwsService initialization the helloWorld service bean is not available.

This needs to point to something:
<ref bean="helloWorld">
Do you have something like this defined:
<bean id="helloWorld" class="at.pdts.cxf.HalloServiceImpl" />
That error means that Spring could now find a spring bean with the alias "helloWorld."
Perhaps posting your entire spring.xml and the java code to HelloWorldImpl would help.
EDIT: Your config confirms my theory.
<ref bean= says "inject something else here". But you have not defined that bean, hence the exception No Such Bean Definition. Furthermore, I was able to make your code work by creating my own implementation of HalloService (HalloServiceImpl) with a custom scream method that returned a blank string. Then I added it to the spring configuration: <bean id="helloWorld" class="at.pdts.cxf.HalloServiceImpl" />
EDIT #2: Another way to make it work is by eliminating HalloService:
<jaxws:server id="jaxwsService" serviceClass="at.pdts.cxf.HelloWorld" address="/hello">
<jaxws:serviceBean>
<bean class="at.pdts.cxf.HelloWorldImpl" />
</jaxws:serviceBean>
</jaxws:server>
</beans>
HelloWorldImpl.groovy
package at.pdts.cxf
import javax.jws.WebService
#WebService(endpointInterface = "at.pdts.cxf.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
public String sayHi(String text) {
return "hello scream!" + text
}
}
Basically your choices are: Provide Spring an implmentation of HalloService, or don't reference it in your Spring.xml.
EDIT #3: There is a misunderstanding around the purpose of InitializingBean:
From the javadoc:
InitializingBean Interface to be implemented by beans that need to
react once all their properties have been set by a BeanFactory: for
example, to perform custom initialization, or merely to check that all
mandatory properties have been set.
Implementing InitializingBean just means that afterPropertiesSet() will be called. It does not mean the Spring will automatically add this bean to your Spring Config. You still must declare the bean in your spring configuration with this line:
<bean id="halloService" class="at.pdts.cxf.HalloService" />

I missed this the first time I read your question but you are defining your bean in applicationContext.xml. When I was making a test case for your question, I was putting my bean definition in grails-app/conf/spring/resources.xml. Try creating that file and putting the following into it:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:lang="http://www.springframework.org/schema/lang"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<!--create the bean for the service, link to groovy service bean -->
<jaxws:server id="jaxwsService" serviceClass="at.pdts.cxf.HelloWorld" address="/hello">
<jaxws:serviceBean>
<bean class="at.pdts.cxf.HelloWorldImpl">
<property name="halloService" ref="halloService" />
</bean>
</jaxws:serviceBean>
</jaxws:server>
</beans>
