如何在Spring Boot中加载和遍历属性文件 [英] How to load and iterate through properties file in Spring Boot

问题描述

我有一个properties文件，其中的值以逗号分隔.我能够获得如下所示的Object值.谁能告诉我如何将值分开并以String形式获取.

I've a properties file in which the values are comma separated. I'm able to get the values as Object as below. Could anyone please tell me how to separate the values and get it in String.

.properties

key-1 = value1,value11
key-2 = value2,value22
key-3 = value3,value33
key-4 = value4,value44

代码

@PropertySource( value = "classpath:test1.properties", name = "test1" )

AbstractEnvironment ae = (AbstractEnvironment)env;
org.springframework.core.env.PropertySource test1Source = 
ae.getPropertySources().get("test1");
Properties propsTest1 = (Properties)test1Source.getSource();

   for(Object key : propsTest1.keySet()){
   System.out.println("Properties file======>   propsTest1.get(key));
  }

推荐答案

您可以尝试以下操作.

Properties propsTest1 = (Properties)test1Source.getSource();

for(Map.Entry<Object, Object> e : propsTest1.entrySet()){

   String value = (String)e.getValue();
   String[] values = value.split(",");
   // If you have spaces as between values, you have to take care of it.
}
