I am trying to read properties from application.yml in spring-bean.xml like this:
<bean name="#{bean.name}" />
Is it possible ? or I should specify location of my application.yml file?
Yes It's Possible
For YAML Properties
You have to use YamlPropertiesFactoryBean
<bean id="yamlProperties" class="org.springframework.beans.factory.config.YamlPropertiesFactoryBean">
<property name="resources" value="classpath:application.yml"/>
</bean>
<context:property-placeholder properties-ref="yamlProperties"/>
Then define your property in src/main/resource/application.yaml
bean:
name: foo
Now use can use the property in xml to create a bean
<bean name="${bean.name}"
class="net.asifhossain.springmvcxml.web.FooBar"/>
Here's my complete XML config
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<bean id="yamlProperties" class="org.springframework.beans.factory.config.YamlPropertiesFactoryBean">
<property name="resources" value="classpath:application.yaml"/>
</bean>
<context:property-placeholder properties-ref="yamlProperties"/>
<bean name="${bean.name}" class="net.asifhossain.springmvcxml.web.FooBar"/>
</beans>

How can I get the command line arguments in a xml configuration file with spring?
With property file I can write this:

But how can I explain Spring to get the values from command line arguments instead of property file specified in property-placeholder?
Thanks
To read from property file use
<property name="prop1" value="${value.from.property}" />
To read from Job Parameter use
<property name="prop1" value="#{jobParameters['value.from.jobParameter']}" />
I need to access a property file outside war. I am keeping path to the outside property
file in a class path property file. The Project version is Spring 2.5.1 and
#Configuration and Environemnt classes are not available unfortunately.
System.properties is in the class path it has key entry to the outside property.
key.externalFile=C:\temp\external.properties
I tried with below approach
<context:property-placeholder location="classpath:System.properties"/>
<context:property-placeholder location="file:${key.externalFile}" />
In the external.properties file it has id
keyValue= 444;
I need to inject this value to a bean as below.
<bean id="helloWorldBean" class="com.java.snippets.enterprise.services.HelloWorld">
<property name="key" value="${keyValue} />
I am getting the error Could not resolve placeholder 'keyValue' in string value "${keyValue}"
I also tried out with
<context:property-placeholder location="file:${key.supportiveFile}" />
<util:properties id="props" location="file:${key.supportiveFile}"/>
but it ended with the same results.
<bean id="helloWorldBean"
class="com.java.snippets.enterprise.services.HelloWorld">
<property name="key" value="${props.keypath}" />
</bean>
Please help me and looking forward.

Remove the context attribute definitions of propertyPlaceholderConfigurer and replace them with:

Actually the question asked on SO continue. According to my spring-servlet.xml configuration for internationalization, I can not change the language of request. When I send request including "?language=tr" it returns me messages from en file. Any help would be appreciated.

Rather make sure that you added the localeChangeInterceptor bean within the interceptors properties of your handleMapping bean as follows:
<bean id="handlerMapping"vclass="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<list>
<ref bean="localeChangeInterceptor" />
</list>
</property>
</bean>
Or try to register the LocaleChangeInterceptor as an mvc:interceptor:
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"
p:paramName="language" />
</mvc:interceptors>
You need to add the mvc namespace schema (xmlns:mvc="http://www.springframework.org/schema/mvc") in the root declaration of the spring context file so it may look as:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

I would like to initialize my MessageSource field with Dependency Injection in Spring. This is what have so far:
package com.ucmas.cms.view;
#Component
public class PdfRevenueReportView extends AbstractPdfView {

#Autowired
private MessageSource messageSource;
...
}

I have defined my messageSource in root-context.xml
<bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="classpath:messages" />
<property name="defaultEncoding" value="UTF-8" />
</bean>
My controller classes work fine, however I am unable to inject the messageSource field in the PdfRevenueReportView class. What should I do to make the DI works ?
UPDATED
I define the view in xml 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 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<bean id="PdfRevenueSummary" class="com.ucmas.cms.view.PdfRevenueReportView" />
</beans>
Perhaps this is why the messageSource is always null ?
I got it working by updating my spring-pdf-views.xml into
<?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 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<bean id="PdfRevenueSummary" class="com.ucmas.cms.view.PdfRevenueReportView">
<property name="messageSource" ref="messageSource"/>
</bean>
</beans>
However this requires me to generate setter and getter for messageSource field and removing the #Autowired annotation.
In your dispatcher servlets configuration you need to create a bean for the message source.
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="directory/with/messagesource"/>
</bean>
Also ensure that the messages directory is on the classpath.
You are annotating messageSource with Autowired. This might not work when your bean messageSource whilst is an interface of MessageResource, is really the implementation ResourceBundleMessageSource.
I think your DI would have worked if you used #Resource instead as it is name based:
#Resource
private MessageSource messageSource;
This is syntax which is working
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:application.properties"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
</bean>
This is alternative format which is NOT working
<context:property-placeholder location="classpath:application.properties" system-properties-mode="OVERRIDE"/>
Any ideas why? I will always crach on tests while building.
Application properties file contains just this
hibernate.show.sql = false
hibernate.format.sql = true
Your syntax looks correct. Do you have the context namespace registered in your context file?
For example:
<beans ...
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="...
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
