To get messages from message.properties files your need to
add below bean in xml file
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<value>messages</value>
</property>
</bean>
If you want to display in main method, use below code
to display property message
System.out.println(context.getMessage("greeting", null, "Default
Greeting", null));
If you want to use in any of the other beans then
you need configure “private
MessageSource messageSource;” and need to Autowired in that class to read
properties from .properties file.
private MessageSource messageSource;
System.out.println(this.messageSource.getMessage("greeting", null, "Default
Greeting", null));
public void
setMessageSource(MessageSource messageSource) {
this.messageSource =
messageSource;
}
public MessageSource
getMessageSource() {
return messageSource;
}
To add dynamic values to your property.
System.out.println(this.messageSource.getMessage(
"drawing.point",
new Object[]{center.getX(),center.getY()},
"Default point message",
Locale.ENGLISH));
drawing.point=Circle:
({0},{1})
