从外部文件夹加载Spring资源类

标签: spring resources message

我有一个spring项目名称:SpringExample

目录结构:

enter image description here

spring的locale.xml:

<bean id="customerService" class="com.mkyong.customer.services.CustomerService" />

<bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basename">
        <value>\SpringExample\conf‬\messages</value>
    </property>
</bean>

CustomerService的代码:

 package com.mkyong.customer.services;


    public class CustomerService implements MessageSourceAware
    {
        private MessageSource messageSource;

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

        public void printMessage(){
            String name = messageSource.getMessage("customer.name", 
                    new Object[] { 28, "http://www.mkyong.com" }, Locale.US);
            System.out.println("Customer name (English) : " + name);

    }

app类(主类)的代码:

package com.mkyong.common;

import java.util.Locale;

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

import com.mkyong.customer.services.CustomerService;

public class App {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext(
                new String[] { "locale.xml" });

        // get the message resource inside context
        String name = context.getMessage("customer.name", new Object[] { 28,
                "http://www.mkyong.com" }, Locale.US);
        System.out.println("Customer name (English) : " + name);


        // get the message resource inside the bean
        CustomerService cust = (CustomerService) context
                .getBean("customerService");
        cust.printMessage();
    }
}

但它无法捆绑proprtie文件,因为它不在包中。 我得到例外:

  

警告:找不到ResourceBundle [\ SpringExample \ conf?\ messages]   MessageSource:找不到基本名称的包   \ SpringExample \ conf?\ messages,locale en_US

如何将它与外部文件夹资源捆绑在一起?就像我的例子一样?

答案 0 :(得分:3)

conf目录设为maven资源目录(maven build helper plugin)或将文件从conf移至src\main\resources。然后修改ResourceBundleMessageSource以从类路径根加载消息,因为src\main\resources对应于类路径根。

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

注意:如果您使用ReloadableResourceBundleMessageSource代替ResourceBundleMessageSource,则必须使用前缀classpath:作为basename属性值classpath:messages
