我想阅读具有地图地图的弹簧属性文件

Question

我想要一个像下面这样的属性，它是地图

propertymap = {
    key1:'{subkey1:'subvalue1',subkey2:'subvalue2'}',
    key2:'{subkey3:'subvalue3',subkey4:'subvalue4'}' }

@Value("#{${propertymap}}")  
private Map<String,Map<String,String>> propertymap;

在我的配置类中使用了类似上面的代码，但出现错误。请让我知道是否有办法做到这一点。

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.util.Map  nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.expression.spel.SpelParseException: EL1043E:(pos 17): Unexpected token. Expected 'rcurly(})' but was 'identifier'

Answer 1

我找到了方法，我只需要删除键后的 '

propertymap = {  
   key1:{  
      subkey1:'subvalue1',
      subkey2:'subvalue2'
   },
   key2:{  
      subkey3:'subvalue3',
      subkey4:'subvalue4'
   }
}

和下面的代码把它捡起来

@Value("#{${propertymap}}")  
private Map<String,Map<String,String>> propertymap;
