Accessing 'message.properties' values

[Anoop]

Hay

How can I access the values that I had declared in my ‘message.properties’ to my business logic (ie, java code).
I can access the same in JSP using JSTL like;

<p>
<fmt:message key="user.loginName"/><br>
<fmt:message key="user.password"/>
</p>

Similarly I need the value of ‘user.loginName’ to my java code. How it is possible?

Thanks
Anoop.

can anyone shed more light on this? How do we access the message.props in our controllers/java beans?

Hi,

here is what you have to do:

1) Declare the following bean in your Spring context:

<bean id="messageSource" class="org.springframework.context.support.ResourceBundle MessageSource">
<property name="basename"><value>messages</value></property>
</bean>

It contains the basenames of your .properties files.

2) Make your controller (or any other bean declared in your context) implement the MessageSourceAware interface: http://www.springframework.org/docs/api/org/springframework/context/MessageSourceAware.html

3) Use the injected MessageSource object: http://www.springframework.org/docs/api/org/springframework/context/MessageSource.html
Messages will be fetched from the .properties files declared above.

Cheers,

Sergio B.

I'm satill having a lot of trouble trying to implment this...

ApplicationContext.xml :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundle MessageSource">
<property name="basename"><value>messages</value></property>
</bean>

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyP laceholderConfigurer">
<property name="location" value="/WEB-INF/jdbc.properties"/>
</bean>

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerD ataSource">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>

</beans>


Inside my dispatch-servlet.xml :


...
<bean name="camSelectController" class="web.controller.CamSelectController">
</bean>
...



And finally my controller :


package web.controller;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.*;
import org.springframework.web.servlet.view.RedirectView;
import org.springframework.web.bind.ServletRequestUtils;

import javax.servlet.*;
import javax.servlet.http.*;

import java.io.*;
import java.util.*;

import org.apache.commons.logging.*;

import web.account.*;
import web.common.*;

import org.springframework.context.MessageSourceAware;
import org.springframework.context.MessageSource;

public class CamSelectController implements MessageSourceAware {


private MessageSource messageSource;

public void setMessageSource (MessageSource messageSource) {
this.messageSource = messageSource;
}

public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws Exception {

log.info (messageSource.getMessage("logo", null, Locale.CHINESE))

return new ModelAndView("camSelect");
}
}



Then I get thrown an error like this:

javax.servlet.ServletException: No adapter for handler [web.controller.CamSelectController@132d584]: Does your handler implement a supported interface like Controller?

Any code examples that other ppl have successfully used would be much appreciated! I learn best from examples!

Thanks!

Your CamSelectController needs to either implement the org.springframework.web.servlet.mvc.Controller interface or extend one of the many abstract controllers Spring provides.
