操作properties文件总结

1.spring读取

///////////////////////////////////////////////////////////////////////////////////////
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
            <property name="basenames">
                <list>
                    <value>buttons</value>
                    <value>labels</value>
                </list>    
            </property>
    </bean>
</beans>


///////////////////////////////////////////////////////////////////////////////////////

import java.util.Locale;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class MessageSourceDemo {

    public static void main(String[] args) {
        ApplicationContext ctx = new FileSystemXmlApplicationContext(
                "build/messageSource.xml");

        Locale english = Locale.ENGLISH;
        Locale czech = new Locale("cs", "CZ");

        System.out.println(ctx.getMessage("msg", null, english));
        System.out.println(ctx.getMessage("msg", null, czech));
        
        System.out.println(ctx.getMessage("nameMsg", new Object[] { "Rob",
                "Harrop" }, english));
    }
}

 2.java ResourceBundle读取

messages.properties位于项目根目录下

在这个文件中，内容如下： key=value .... 

ResourceBunlde bundle = ResourceBundle.getBundle("messages"); 

bundle.getMessage(key); 

即可获得message的value
