Spring. How to add same property to multiple beans?

Consider I have something like this in beans.xml:
<bean id="emails" class="org.some.package.SomeClass">
<property name="emailList">
<list>
<value>pechorin#hero.org</value>
<value>raskolnikov#slums.org</value>
<value>stavrogin#gov.org</value>
<value>porfiry#gov.org</value>
</list>
</property>
</bean>
But I need to add emailList property into multiple beans. How can I do that without writing property to each bean? Can externalize property and inject it into each bean?
I expect something like:
<property name="commonProp">
<list>
<value>pechorin#hero.org</value>
<value>raskolnikov#slums.org</value>
<value>stavrogin#gov.org</value>
<value>porfiry#gov.org</value>
</list>
</property>
<bean id="emailsOne" class="org.some.package.ClassOne">
<property name="emailList" ref="commonProp" />
</bean>
<bean id="emailsTwo" class="org.some.package.ClassTwo">
<property name="emailList" ref="commonProp" />
</bean>

You can do it using: util:list
<util:list id="myList" value-type="java.lang.String">
<value>foo</value>
<value>bar</value>
</util:list>
Then use this myList reference in other beans.

java.util.Properties: How do I retrieve values from Properties in spring config xml

I have a java.util.Properties object which has few key value pairs in it. I am trying to use this Property object in the spring configuration file i.e. define the key in the spring config and during runtime, it should get the value from the properties object.
For ex:
<bean id="test" class="com.sample.Test">
<constructor-arg value="${PROPERTY_KEY} />
</bean>
Now during the runtime, the constructor should get the value that is present in the Property object.
Is there a way to get this done ?
Note: I do not want to use config.properties here. Looking to use java.util.Properties
Thanks,

<context:property-placeholder location="classpath:placeholder.properties"/>
or
<bean id="properties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:<file-name>.properties" />
</bean>

First you have to create bean to access your property file, like below
<bean id="appProperties"
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="singleton" value="true" />
<property name="ignoreResourceNotFound" value="true" />
<property name="locations">
<list>
<value>classpath*:localhost-mysql.properties</value>
<value>classpath*:mail-server.properties</value>
</list>
</property>
</bean>
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties" ref="appProperties" />
</bean>
Next you can access Key-Value pair from your property files, like below
<bean id="mailServerSettings" class="com.ratormonitor.app.context.EmailSettings">
<property name="host" value="${mail.server.host}" />
<property name="port" value="${mail.server.port}" />
<property name="username" value="${mail.server.username}" />
<property name="password" value="${mail.server.password}" />
<property name="requestContextPath" value="${request.context.path}" />
</bean>
Hope this code will solve your problem.

You can use Spring Expression Language (SpEL) to get a java object value in spring configuration xml file.
An example :
<property name="misfireInstruction"
value="#{T(org.quartz.CronTrigger).MISFIRE_INSTRUCTION_FIRE_ONCE_NOW}"/>

So this is how I did:
As I said I had a java.util.Properties object. I then created a CustomProperty class which extended PropertySource>
public class CustomPropertySource extends PropertySource<Map<String, Object>>
Then in my main class I did the following:
AbstractApplicationContext context = new ClassPathXmlApplicationContext(new String[] {springConfigLocation, false);
context.getEnvironment().getPropertySources.addlast(new CustomPropertySource("custom", propertiesObject));
conext.refresh();
And then in the spring config file, I had to add this:
<context: property-placeholder ignore-unresolvable="true"/>
So in this way, I could fetch values for the keys defined in the spring config file, just like how we get the values from property files.

Order of bean initialization in Spring

I have the following beans in my Spring config file:
<bean id="myList" class="java.util.ArrayList">
<constructor-arg>
<list>
<ref bean="elem1"/>
<ref bean="elem2"/>
<ref bean="elem3"/>
<ref bean="elem4"/>
</list>
</constructor-arg>
</bean>
<bean id="elem4" class="myClass">
<property name="title" value="random4"/>
</bean>
<bean id="elem1" class="myClass">
<property name="title" value="random1"/>
</bean>
<bean id="elem3" class="myClass">
<property name="title" value="random3"/>
</bean>
<bean id="elem2" class="myClass">
<property name="title" value="random2"/>
</bean>
I have noticed that in my application the elements in myList are in the following order: elem4, elem1, elem3, elem2. I was expecting that the elements in my list will be in the order I set when I declared the ref beans ( elem1, elem2, elem3, elem4).
Is there an order in which Spring initializes beans?
Is there a way I can specify an order for the elements in my list?

The spring does respect the order you gave in the list. The elements in the list would exactly be the [elem1,elem2,elem3,elem4] as you specified. Otherwise, you are doing something wrong, can you show the code which prints you the different order?
The order of bean initialization however may be different and depends on bean dependencies, so, for example if you have two beans
<bean id="holder" class="my.HolderBean" lazy-init="false">
<property name="inner" ref="inner"/>
</bean>
<bean id="inner" class="my.InnerBean" lazy-init="false"/>
Then regardless of the xml definition order, the InnerBean will be initialized first, then during HolderBean initialization it will be injected into HolderBean.

Can't load multiple property files in spring's application context

I have three property files placed in a resource folder in classpath. The problem i am facing is while i am able to load invidual files separately i am unable to load them when they are declared together.
Please see the XML below:
<bean name="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames" value="resources\label"/>
</bean>
This is working but the XML given below isn't:
<bean name="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames" value="resources\label,resources\button,resources\messages"/>
<property name="cacheSeconds" value="1"/>
</bean>
I wish to declared them together as I wish to use a single bean to access all three files. Help required!

Found the answer . It should be like this `
<property name="basenames">
<list>
<value>classpath:resources\label</value>
<value>classpath:resources\button</value>
<value>classpath:resources\messages</value>
</list>
</property>
</bean>

Do it like this
<property name="basenames">
<list>
<value>resources\label</value>
<value>resources\button</value>
<value>resources\messages</value>
</list>
</property>

Calling method in Bean property attribute

I have a simple bean tag in the bean xml file as shown below. This is just a dummy values
<bean id="myBeanId" class="myBeanClass">
<property name="myProperty" value=${myPassword} />
</bean>
<bean id ="myOtherBeanId" class="myOtherBeanClass">
<property name="myOtherProperty" ref="myBeanId">
</bean>
myPassword is a variable names stored in a separate properties file. Now, I instead of storing the direct value of myPassword from the properties file, I will have encrypted string in the property file and I want to call my custom written Decrypt method on myPassword property instead. something like this.
<bean id="myBeanId" class="myBeanClass">
<property name="myProperty" value=com.xxx.Security.Decrypt(${myPassword}) />
</bean>
How can I do this?

Use the MethodInvokingFactoryBean if you want to invoke another bean's method and use the returned object as a bean.
<bean id="securityBean" class="com.xxx.Security">
</bean>
<bean id="myBeanId" class="myBeanClass">
<property name="myProperty">
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject"><ref local="securityBean"/></property>
<property name="targetMethod"><value>Decrypt</value></property>
<property name="arguments">
<list>
<value>${myPassword}</value>
</list>
</property>
</bean>
</property>
</bean>

How about Using with jaspyt,
Properties file entry
password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm)
Bean Entry
<bean id="myBeanId" class="myBeanClass">
<property name="myProperty" value=${password} />
</bean>
