Using values from properties file in spring roo

Question

I'm new to spring and spring-roo. I try to build an application and read some key value pairs from a properties file.

I created a myconfig.properties file and saved it to src/main/resources/META-INF/spring/. The content of the file is:

## My Configuration settings
myconfig.url=https://1.2.3.4/api.php
myconfig.username=user1
myconfig.password=password1

Now I added a bean configuration into appilcationContext.xml in the same directory

  <bean id="MyConfig" class="com.test.client.MyClient">
    <property name="url" value="${myconfig.url}" />
    <property name="username" value="${myconfig.username}" />
    <property name="password" value="${myconfig.password}" />
</bean>

In my class file I tried to access the values, but I get an File not found error

     package com.test.client;

     import org.springframework.context.support.AbstractApplicationContext;
     import org.springframework.context.support.ClassPathXmlApplicationContext;
     import org.springframework.roo.addon.javabean.RooJavaBean;
     import org.springframework.roo.addon.jpa.activerecord.RooJpaActiveRecord;
     import org.springframework.roo.addon.tostring.RooToString;
     import org.springframework.util.LinkedMultiValueMap;
     import org.springframework.util.MultiValueMap;
     import org.springframework.web.client.RestTemplate;

     @RooJavaBean
     @RooToString
     @RooJpaActiveRecord
     public class MyClient {

         private String url;

         private String username;

         private String password;


         public static String login()
 {
    // Construct the spring application context
    AbstractApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

    MyClient config = (MyClient) context.getBean("MyConfig");

    // Register hook to shutdown Spring gracefully
    // See http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/beans.html#beans-factory-shutdown
    context.registerShutdownHook();

    String token = null;

    final String url = config.getUrl();
    final String username = config.getUsername();
    final String password = config.getPassword();

  ....

Thanks for any help!

Try

AbstractApplicationContext context = new ClassPathXmlApplicationContext("classpath*:META-INF/spring/applicationContext.xml");

However the best practice is to implement interface ApplicationContextAware.
