使用EL检索网页上Enum的String值的最佳实践

Question

My object:

public class Account(){
    private String accountName;
    private AccountType accountType; // enum 

    //I customized the getter by doing this...
    public String getAccountType(){
      return accountType.getAccountType();
    }
}

My AccountType Enum:

public enum AccountType{
    OLD("Old account"),
    NEW("New account");

    private final String accountType;
    private AccountType(String accountType){
       this.accountType = accountType;
    }
    public String getAccountType(){
       return accountType;
    }

}

I use ${account.accountType} to retrieve the value of the enum constant. Is this the correct way to do it?

I tried using AccountType.valueOf("OLD") but it returned OLD .

What's the best practice for things like these?

Answer 1

Change your enum class like this;

public enum AccountType{
    OLD {
       public String type() {
           return "Old account";
       } 
    },
    NEW {
        public String type() {
            return "New account";
        }
    };
 }

and your Account object like this;

   public class Account(){
        private String accountName;    
        private AccountType accountType; // enum 

        //You don't need this.
        //public String getAccountType(){
        //    return accountType.getAccountType();
        //  }
    }

Then you can access accountType.type
