使用屬性文件中的值在春天roo

Question

我是新來的春天和春天roo。我嘗試構建應用程序並從屬性文件中讀取一些鍵值對。

我創建了一個myconfig.properties文件並將其保存到src/main/resources/META-INF/spring /。 文件的內容是：

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

現在我加了一個bean的配置到appilcationContext.xml在同一目錄

<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> 

在我的類文件，我試圖訪問值，但我得到文件未找到錯誤

 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(); 

    .... 

感謝您的幫助！

嘗試

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

然而，最好的做法是實現接口ApplicationContextAware。
