Spring MVC 2.5：如何加载属性文件 [英] Spring MVC 2.5: how to load properties file

问题描述

我需要加载许多属性文件，这些文件位于资源文件夹中。

我有一个名为abc_en.properties的资源，其内容如下：

a = x

b = y

c = z

<我需要在Java方法中使用属性sing java.util.Properties：

  java.util.Properties reportProperties = new java.util.Properties（）; 
 ... 
字符串a = reportProperties.getProperty（a）; 
  

我该怎么做？

谢谢

解决方案

您需要在上下文文件中定义propertyConfigurer bean：

 < bean id =propertyConfigurer
 class =org.springframework.beans.factory.config.PropertyPlaceholderConfigurer> 
< property name =locations> 
< list> 
< value> classpath：abc.properties< / value> 
< value> classpath：efg.properties< / value> 
< / list> 
< / property> 
< / bean> 
  

编辑：

要使用 java.util.Properties ，您需要在上下文文件中定义 PropertiesFactoryBean bean：

 < bean id =propertiesclass =org.springframework.beans.factory.config.PropertiesFactoryBean> 
< property name =location> 
< list> 
< value> classpath：abc_en.properties< / value> 
< value> classpath：abc_fr.properties< / value> 
< / list> 
< / property> 
< / bean> 
  

然后在你的班级中你需要定义一个 java.util.Properties varible并将属性bean加载到其中：

  public class MyClass {
 
 @Autowired 
 private java.util.Properties properties; 
 
 
 public void myMethod（）{
 String a = properties.getProperty（a）; 
 String b = properties.getProperty（b）; 
 String c = properties.getProperty（c）; 
} 
} 
  

还有其他方法可以将属性bean加载到您的身上class，但如果您使用 @Autowired 注释，则需要输入< context：annotation-config /> 你上下文文件中的元素。

I need to load many properties files, which are in the resources folder.

I have a resource called abc_en.properties with the content below:
a = x
b = y
c = z

and I need to use the properties sing java.util.Properties in a Java Method:

  java.util.Properties reportProperties = new java.util.Properties();   
   ...
  String a = reportProperties.getProperty("a");

How can I do this?

Thanks

解决方案

You need to define the propertyConfigurer bean in your context file:

<bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:abc.properties</value>
            <value>classpath:efg.properties</value>
        </list>
    </property>
</bean>

EDIT:

In order to use java.util.Properties you need to define the PropertiesFactoryBean bean in your context file :

    <bean id="properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
          <property name="location">
               <list>
                 <value>classpath:abc_en.properties</value>
                 <value>classpath:abc_fr.properties</value>
               </list>
          </property>
        </bean>

Then in your class you need to define a java.util.Properties varible and load the properties bean into it :

public class MyClass {

     @Autowired
     private java.util.Properties properties;


     public void myMethod() {
         String a = properties.getProperty("a");
         String b = properties.getProperty("b");
         String c = properties.getProperty("c");
     }
}

There are other ways to load the properties bean into you class, but if you use the @Autowired annotation, you need to put the <context:annotation-config /> element in you context file.
