How to load and iterate through properties file in Spring Boot

Sam :

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

Code

@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));
  }

Vinay Avasthi :

You can try something like below.

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.
}
