1 首先在applicationContext.xml中加入：

   <beans xmlns:util="http://www.springframework.org/schema/util" 

    xsi:schemaLocation="http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.1.xsd"> 

</beans> 

 

   的命名空间，然后

2

<util:properties id="settings" location="WEB-INF/classes/META-INF/spring/test.properties" />

3 创建test.properties

   abc=123

4

import org.springframework.beans.factory.annotation.Value;  

import org.springframework.stereotype.Controller;  

import org.springframework.web.bind.annotation.RequestMapping;  

 

@RequestMapping("/admin/images")  

@Controller  

public class ImageAdminController {  

 

    private String imageDir;  

           @Value("#{settings['test.abc']}")  

    public void setImageDir(String val) {  

        this.imageDir = val;  

    }

} 

这样就将test.abc的值注入了imageDir中了
