Hi Rajeenthini,
AFAIK ability to convert a POJO into JSON object does nor affect the output
of a Jaggery Log of that POJO.
To get a proper log output for a Java object, you need to implement the
"toString" method in that Java class. For example in your case,
public class Student {
...
public String toString() {
return "{name: " + this.name + ", age: " + this.age + ", indexNo: " +
this.indexNo + "}";
}
}
Now you can log a Student object in your Jaggery code as following.
log.info(studentObj.toString());
Thanks.
