How to Load lables via Properties file in FreeMarker - spring-mvc

I am using Spring MVC + FreeMarker integration. As I am new to FreeMarker i am not able to find out a way to configure FreeMarker labels from properties file.
Kindly help me out on this.
Thanks.

You can use, 'ResourceBundleMessageSource', message source for this.
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource"
<property name="basename" value="classpath:messages/messages" />
<property name="defaultEncoding" value="UTF-8"/>
/>
Define the locale resolver,
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en" />
</bean>
Define localeChangeInterceptor which detects the language parameter from the user session and call locale resolve. And register the interceptor in handler Mappings.
<bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" >
<property name="interceptors">
<list>
<ref bean="localeChangeInterceptor" />
</list>
</property>
</bean>
Property files need to be defined like,
messages_en.properties
messages_ar.properties
inside the messages folder path.
'ReloadableResourceBundleMessageSource' can be used if the language property files frequently changes. That means you don't have to restart the application in each language file change.
You need to import spring macro,
<#import "/spring.ftl" as spring/>
and
messages can be accessed inside a .ftl as follows.
<#spring.message "customMessageKey"/>

Content Negotiation in Spring by AbstractCachingViewResolver order attribute uses

p:order="1" what does have it means to my application.
Is is any kind of priority of loading of beans classes in my application.
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="2" />
<property name="interceptors">
<list>
<ref bean="localeChangeInterceptor"/>
</list>
</property>
<property name="defaultHandler">
<bean class="org.springframework.web.servlet.mvc.UrlFilenameViewController"/>
</property>
</bean>
<bean id="ajaxViewResolver" class="org.springframework.js.ajax.AjaxUrlBasedViewResolver" p:order="1">
<property name="viewClass" value="org.springframework.js.ajax.tiles3.AjaxTilesView"/>
</bean>
<bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver" p:order="2">
<property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"/>
</bean>
in second code p:order="1" is the order of deployment/loading beans in container
I found It Helpful so sharing it.The order is an order of resolving the views by Spring framework.
Went to a blog and a documentation.
A spring Blog
Documentation
When chaining ViewResolvers, a UrlBasedViewResolver always needs
to be last, as it will attempt to resolve any view name, no matter whether
the underlying resource actually exists.

Alfresco: Why is there no Scripts Extension folder, when there is a Web Script Extension folder?

When I learnt about web scripts, the tutorials said to leave the Web Scripts folder alone and instead to add my web script to the Web Scripts Extensions folder. My understanding is that this is so that I do not pollute Alfresco's out-of-the-box web scripts, and upgrading will be easier.
Why is there no equivalent extensions folder for the Scripts folder?
Or is my understanding of the reason for the Web Scripts vs Web Scripts Extensions folders wrong?
Extension folders provide a way to override default behavior. You can put your code there if you like, but doing so makes it more difficult to override it. I will use the repository as an example. Similiar logic applies to share.
Have a look at alfresco/WEB-INF/classes/alfresco/web-scripts-application-context.xml. It reads:
<bean name="webscripts.store.repo.extension" parent="webscripts.repostore">
<property name="store"><value>workspace://SpacesStore</value></property>
<property name="path"><value>/${spaces.company_home.childname}/${spaces.dictionary.childname}/cm:extensionwebscripts</value></property>
</bean>
<bean name="webscripts.store.repo" parent="webscripts.repostore">
<property name="mustExist"><value>true</value></property>
<property name="store"><value>workspace://SpacesStore</value></property>
<property name="path"><value>/${spaces.company_home.childname}/${spaces.dictionary.childname}/cm:webscripts</value></property>
</bean>
<bean id="webscripts.repoclasspathstore" class="org.alfresco.repo.web.scripts.RepoClassPathStore" abstract="true" />
<bean id="webscripts.store" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>false</value></property>
<property name="classPath"><value>webscripts</value></property>
</bean>
<bean id="webscripts.store.alfresco" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>false</value></property>
<property name="classPath"><value>alfresco/webscripts</value></property>
</bean>
<bean id="webscripts.store.client" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>true</value></property>
<property name="classPath"><value>alfresco/templates/webscripts</value></property>
</bean>
<bean id="webscripts.store.client.extension" parent="webscripts.classpathstore">
<property name="classPath"><value>alfresco/extension/templates/webscripts</value></property>
</bean>
<bean id="webscripts.searchpath" class="org.springframework.extensions.webscripts.SearchPath">
<property name="searchPath">
<list>
<ref bean="webscripts.store.repo.extension" />
<ref bean="webscripts.store.repo" />
<ref bean="webscripts.store.client.extension" />
<ref bean="webscripts.store.client" />
<ref bean="webscripts.store.alfresco" />
<ref bean="webscripts.store" />
</list>
</property>
</bean>
The searchPath property of webscripts.searchpath shows the search order. Search terminates as soon as it has a match. As you can see, it is no problem to put custom code in non extension locations as long as their path is unique.
I personally only put override webscripts in extension locations.
You can create a folder under Scripts called Extension and put all your script in that. Or just create different folders under Scripts for each function or project, it doesn't matter. They get picked up by Alfresco.

Spring MVC and Shiro Configuration using ini files

I'm trying to set up an environment with Spring MVC and Apache Shiro. I'm following articles mentioned in shiro.apache.org.
I'm using Spring's DelegatingFilterProxy as Shiro Filter in web.xml.
The current filtering is done using :
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"/>
<property name="loginUrl" value="/login"/>
<property name="successUrl" value="/dashboard"/>
<property name="unauthorizedUrl" value="/unauthorized"/>
<property name="filterChainDefinitions">
<value>
/** = authc, user, admin
/admin/** = authc, admin
/login = anon
</value>
</property>
</bean>
Question is, how do I use shiro.ini file defining security settings?
You don't need to use shiro.ini. All of the rest of your configuration can (and should, since you're using ShiroFilterFactoryBean) be done in Spring.
For example, adding a securityManager and ehCache based cache manager to your shiroFilter:
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm"/>
<property name="sessionMode" value="native"/>
<property name="sessionManager" ref="sessionManager"/>
<property name="cacheManager" ref="cacheManager"/>
</bean>
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManager" ref="ehCacheManager"/>
</bean>
<bean id="ehCacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"/>
<bean id="sessionDAO"
class="org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO"/>
<bean id="sessionManager"
class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">
<property name="sessionDAO" ref="sessionDAO"/>
</bean>
<bean id="myRealm" class="com.foo.MyRealm"/>
You can check shiro documentation here http://shiro.apache.org/reference.html, it contains everything, in spring, as Les said, usually define different beans instead of using the shiro.ini file, but also you can use this file for authentication, use IniRealm like:
<bean id="myRealm" class="org.apache.shiro.realm.text.IniRealm">
<property name="resourcePath" value="classpath:/shiro.ini" />
</bean>

Configuring FreeMarker In Spring Application

I am new to freemarker,but i want to fetch the data from Spring Application to my view which has extension .ftl.I am using ${message} but it displays as usual.It should display the data which is availble in message from Spring Application.
I am configured dispatcherServlet as below
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/WEB-INF/freemarker/"/>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".ftl"/>
</bean>
You don't use InternalResourceViewResolver with Freemarker, you use FreemarkerViewResolver. Replace that, you should be fine.
Also, I suggest not putting your freemarker templates in /WEB-INF/jsp. They're not JSPs, and should never be treated as such.

Best place to put my .poperties files for use with springs PropertyPlaceholderConfigurer?

i have a properties folder and inside of ti contains my jdbc.properties file.
the problem is that i am unable to load it succesfuly as it always complains that it cannot locate the file.
i have the file currently sitting in the roo directopry fo WEB-INF. when i build and compile my spring mvc it does throw any exceptions but as soon as i load the beans from my code using new ClassPathXmlApplicationContext it fails and says it cannot locate my properties file??
here is how my beans look like:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations"> <list> <value>/properties/jdbc.properties</value>
</list> </property> </bean>
<bean id="dataSource1" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${database.driver}" /> <property
name="url" value="${database.url}" /> <property name="username" value="${database.user}"
/> <property name="password" value="${database.password}" /> </bean>
here is a pic of my project structure at present:
You can put the properties files in root of classpath. And use like below.
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations"> <list> <value>classpath:jdbc.properties</value>
</list> </property> </bean>
