Hi,
I have worked on writing Jaggery test for Jaggery-Product.I can observe
when we tried to log the object it always gives us empty JSON
({}).Currently the implementation goes this way when we try to log java
object.
So I was trying to get rid of this observed behavior of Jaggery.I have gone
through a solution.
*using Jackson[1] *
We can convert java object to JSON[2] and can log it.
I have shared the piece of code I have tried out with Jackson below.
*Simple POJO Student class*
public class Student {
private int age;
private String name;
private String indexNo;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getIndexNo() {
return indexNo;
}
public void setIndexNo(String indexNo) {
this.indexNo = indexNo;
}
}
*Simple class to test Jackson*
import com.fasterxml.jackson.databind.ObjectMapper;
import util.Student;
public class MyTest {
public static void main(String args[]){
Student st = new Student();
st.setIndexNo("DS001");
st.setAge(12);
st.setName("kareena");
try{
ObjectMapper mapper = new ObjectMapper();
String jsonInString = mapper.writeValueAsString(st);
System.out.println("************************************************");
System.out.println(jsonInString);
System.out.println("************************************************");
}catch(Exception e){
System.out.print("Exception caught "+ e);
}
}
}
Actual output by above code.
************************************************
{"age":12,"name":"kareena","indexNo":"DS001"}
************************************************
I have added a dependency in the POM.xml
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.3</version>
</dependency>
IMHO we can use the same scenario in case of log JAVA object.Your help and
suggestions are more appreciated and guide me if I am wrong or I can have
better solution than this.
