I am new to spring (3.1) and totally stumped by this problem.
I am trying to access a property value "schdestination" using a PropertyPlaceholderConfigurer that is defined in two property files (one overriding the other).
I want to use #Value to set a field in a class and i just can't find a way to do it without using another bean. Here is my spring XML snippet
<bean id="placeholderProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>/WEB-INF/abc.properties</value>
<value>/WEB-INF/loc.abc.properties</value>
</list>
</property>
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="1" />
</bean>
Any clues please?
#Value("${schdestination}")
private String destination;
should work.
The class that contains the #Value needs to be annotated with #Component and you need to have <context:component-scan/> in your applicationContext.xml.
Are you using it in your web app? That was my case. I was loading property files from application context and somehow they were not visible in the web app package - controllers to be precise. I had to re-declare them in servlet-context.xml, then they are visible and work just fine. I am really hoping somebody might shed some light what could be going on, or whether it is truly an issue to be fixed in Spring.

As I am planning to update from "hibernate3" to "hibernate4" & "spring 3.0.5" to "spring 3.1.4".
I have configured OpenSessionInViewInterceptor in spring 3.0.5 so want to configure same in 3.1.4.
But I am not able to configure flushMode in OpenSessionInViewInterceptor of Spring 3.1.4;
My Previous setting for spring 3.0.5 was:
<bean name="openSessionInViewInterceptor"
class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
<property name="flushMode">
<bean
id="org.springframework.orm.hibernate3.HibernateAccessor.FLUSH_NEVER"
class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean" />
</property>
</bean>
Now tried to configure same for spring 3.1.4 as below:
<bean name="openSessionInViewInterceptor"
class="org.springframework.orm.hibernate4.support.OpenSessionInViewInterceptor">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
<property name="flushMode">
<bean
id="org.springframework.orm.hibernate3.HibernateAccessor.FLUSH_NEVER"
class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean" />
</property>
</bean>
then it throws below exception:
org.springframework.beans.NotWritablePropertyException: Invalid property 'flushMode' of bean class [org.springframework.orm.hibernate4.support.OpenSessionInViewInterceptor]: Bean property 'flushMode' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
And there is no similar class found in alternate to org.springframework.orm.hibernate3.HibernateAccessor in spring 3.1.4
So my question is how to set flushMode property of OpenSessionInViewInterceptor of spring 3.1.4 ?
It looks like a mess, with unbound links to property accessors. I'd guess that a copy-paste job was done without much thinking about cleaning things up given the different inheritance hierarchies. I hate it when that happens…
Can you use the Hibernate 3 version instead? Yes, it really does appear to be there; here's the link: org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor
Longer term, look more carefully whether the Hibernate 4 code does what you want without specifying the flag at all. Unfortunately, you'll have to ignore the documentation (at least for now) and study the source itself.
Searched through some other posts but could not find exactly what I needed, but I would guess this is an easy question..
So I have a property file called myprops.properties
myprops.localProp1=localProp1
myprops.localProp2=localProp2
myprops.systemProp=${systemPropertyName}
Basically, in this property file I want to use the values as is for localProp1 and locapProp2 but for systemProp, I would like to load the system property. Let's assume that the system property is always set.
My spring config xml looks like this...
<bean id="myprops" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<qualifer value="myprops" />
<property name="singleton" value="true"/>
<property name="ignoreResourceNotFound" value="true" />
<property name="locations">
<list><value>classpath:myprops.properties</value></list>
</property>
</bean>
I use the qualifier have this bean autowired and use the qualifier string "myprops" to access it in another class. All the expected values are there except the myprops.systemProp, it still = ${systemPropertyName}.
How would I get this property to be resolved with the actual system property?
I tried the following in my spring config:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties" ref="myprops" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
</bean>
This didn't seem to help..
Any ideas? I'm hoping this is an easy one and I am just misunderstanding a common concept in property configuration.
Note: I had to manually type all the code couldn't copy/paste so please excuse typos.
Thanks.
My current project requires a customized "System date", which means a system date and it's format defined in the i18n properties file. But the class dealing with it is a general utility class but not within the web layer. However the locale(to work out the date format) has to be retrieved from a HttpServletRequest object. I am thinking autowire a HttpServletRequest instance to that utility class. It seems break the design pattern but I guess it is piratical. However it doesn't work. So what is wrong with that and is there any better way to solve the Locale in any other layers in Spring?
Thanks in advance.
Wouldn't it be a lot more elegant to simply overload the utility-class to accept a Locale as parameter on the affected methods. Then you can retrieve the locale in your controller and pass it down to the utility.
I prefer you to use the Spring Framework's SessionLocaleResolver. It will change and store the locale in the session and hence you can get that at any point of code in the application.
Please refer the below mentioned configuration for the same. And also read the Spring Documentation for the same for the better understanding.
<mvc:interceptors>
<ref bean="localeChangeInterceptor"/>
</mvc:interceptors>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang"/>
</bean>
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en"/>
</bean>
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>/WEB-INF/i18n/labels</value>
<value>/WEB-INF/i18n/messages</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8"/>
</bean>
Hope this helps you. Cheers.
I want to load multiple properties files using <util:properties> tag in a spring 3 application.
I searched on the blogs, but cannot get the correct path to do this.
Hopefully somebody give me the answer to overcome this problem.
Actually <util:properties> is just convenient tag for org.springframework.beans.factory.config.PropertiesFactoryBean. And PropertiesFactoryBean does support multiple locations.
So it is possible to create bean with Properties this way:
<bean id="myProps" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="locations">
<list>
<value>classpath:myprops-common.properties</value>
<value>classpath:myprops-override.properties</value>
<value>classpath:some-more-props-here.properties</value>
</list>
</property>
</bean>
My solution
<context:property-placeholder location="classpath*:*.properties,file:/some/other/path/*.properties" />
util:properties seems to support only 1 properties file (reference). You might want to use the configuration suggested by #peperg.
I suppose that everybody that uses spring, uses form binding and validation. And you all defined the messages to display on validation errors. I did it with this in my config:
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource"
p:basename="messages" />
what will happen basically is that it will read messages.properties in my root folder of the project.
But I'd need to put messages in two separate files. Because one part of the app has to be standalone. I tried adding this just after the one above:
<bean id="messageSourceAssistenza"
class="org.springframework.context.support.ResourceBundleMessageSource"
p:basename = "com.mypackage.other.assistenzamessages.properties"
/>
but it can't resolve those messages at all. How to solve this?
You should be able to use ResourceBundleMessageSource.setBasenames that accepts array of base names:
Set an array of basenames, each
following ResourceBundle conventions:
essentially, a fully-qualified
classpath location. If it doesn't
contain a package qualifier (such as
org.mypackage), it will be resolved
from the classpath root.
The associated resource bundles will
be checked sequentially when resolving
a message code. Note that message
definitions in a previous resource
bundle will override ones in a later
bundle, due to the sequential lookup.
Sample configuration as follows:
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<value>messages_1</value>
<value>messages_2</value>
...
<value>messages_n</value>
</list>
</property>
</bean>
