How to get the values from an object path

Question

I have a class and its controller.In the controller i am defining as below:

//controller 
def empData = new Employee(name:'test',joinDate:'03-Jan-2010',qualifications:['Developer','Tester'])
println("emp Info:"+empData);

//class

import groovy.transform.ToString
@ToString
class Employee{
public String name
public Date joinDate
public Map<String,String[]> qualifications
}

In the println i see the path of the object like com.Employee@515 How to get all the details of the empData object instead of path?

In the groovy way it would be: `println empData.properties` . Check out: http://groovy-lang.org/objectorientation.html#properties — Michal_Szulc, Mar 23 '19 at 22:17
@Michal_Szulc Hi i tried your way and in the output i see the value as below: parameter values are:[class:class java.util.ArrayList, empty:false] — Studentlearner, Mar 23 '19 at 22:32
Are you working on a persisted instance of Employee? If not, use `empData.save()` in advance — Michal_Szulc, Mar 24 '19 at 21:02
@Michal_Szulc - I dont want to save those values in the database. — Studentlearner, Mar 25 '19 at 06:48
oh, so why even bother about creating Employee object? `println params` or ensure that Employee is not a domain class. — Michal_Szulc, Mar 25 '19 at 10:51
@Michal_Szulc - i modified my question to give more details about my problem. — Studentlearner, Mar 26 '19 at 05:34
`println object.properties` is working fine, even for not persisted objects: https://majkesz.pl/images/tmp/groovy_properties.png — Michal_Szulc, Mar 26 '19 at 14:13
Oh, is it so hard to spot the difference? Just remove access modifier `public` and it's working fine. — Michal_Szulc, Mar 26 '19 at 23:38

I couple of different things you can do:

Like the comment said you can define you own toString() method in the Domain object and do what you want like this for example:

String toString() {
    String name = ""
    if (lastName) name = name+lastName
    if (firstName) name = name+", "+firstName
    if (middleName) name = name+" "+middleName
    name = name+" - "+position
    name = name+" - "+city
    return name
}

Also you could just print the fields from your object:

println("emp first name Info:"+empData.first_name);
