How to manually reload properties file from Spring messageSource

For spring framework, I want to manually reload data inside properties file. Actually, have to write reload servlet that will manually reload data when I manually run this servlet file.

I have already defined spring configuration for messageSource.

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
        p:basename="classpath:/message" />

But don't want to autoreload at certain amount of time for example can autoreload when setting:

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
            p:basename="classpath:/message"
            p:cacheSeconds="1" />

I tried before by clearCaches() but not autoreload.

It is working now. Need to inject messageSource into servlet file and call clearCache(). It does clear previous properties data and reload updated properties file.

In ReloadServlet.java,

ReloadableResourceBundleMessageSource rs = Global.getBean("messageSource", ReloadableResourceBundleMessageSource.class);
rs.clearCache();

In Global.java,

private static ApplicationContext context;

public static <T> T getBean(String s, Class<T> type) {
        return context.getBean(s, type);
}

Thanks.

I don't know, what you mean manually reload properties file. Spring already provide to load properties file as below.

Configure your properties file in your spring configuration file. Eg. applicationContext.xml or spring-beans.xml

<util:properties id="MY_CONFIG" location="classpath:MY_CONFIG.properties"/>

In your sping bean, inject as below

@Resource(name = "MY_CONFIG")
private Properties properties;

Your servlet invoke that spring bean.

Update

If you would like to load the file from Servlet or other classes directly

Load properties file in Servlet/JSP
