Question

I’ve written the following:

ObjectMapper oMapper = new ObjectMapper();
Object oPOJO = null;

String p_strJSON = "{\"name\" : { \"first\" : \"Joe\", \"last\" : "
    + "\"Sixpack\" },\"gender\" : \"MALE\",\"verified\" : \"false\","
    + "\"userImage\" : \"Rm9vYmFyIQ==\"}";

try
{
    oPOJO = oMapper.readValue(p_strJSON, User.class);
}
catch(Throwable oThrowable)
{
    System.out.println(oThrowable.getMessage());

    throw new RuntimeException(oThrowable);
}

And am getting the following exception message when it executes:

Can not deserialize instance of java.lang.String out of START_OBJECT token at [Source: java.io.StringReader@3eca90; line: 1, column: 1]

Am I using Jackson incorrectly? I’m using the 1.9.6 JAR – do I need to set anything up in the claspath maybe?

Answer 1

Given your user class looks something like this, your code passes

public class User {
  private Name name;
  private String gender;
  private boolean verified;
  private String userImage;

  // getter and setter
}

public class Name {
  private String first;
  private String last;

  // getter and setter
}
