Fluent setters differences between version 1 and version 2 of the SDK for Java

You can use POJOs with fluent setters in the DynamoDB mapping API for V1 and with V2 since version 2.30.29.

For example, the following POJO returns a Customer instance from the setName method:

// V1

@DynamoDBTable(tableName ="Customer")
public class Customer{
  private String name;
  // Other attributes and methods not shown.
  public Customer setName(String name){
     this.name = name;
     return this;
  }
}

However, if you use a version of V2 prior to 2.30.29, setName returns a Customer instance with a name value of null.

// V2 prior to version 2.30.29.

@DynamoDbBean
public class Customer{
  private String name;
  // Other attributes and methods not shown.
  public Customer setName(String name){ 
     this.name = name;
     return this;  // Bug: returns this instance with a `name` value of `null`.
  }
}

// Available in V2 since version 2.30.29.

@DynamoDbBean
public class Customer{
  private String name;
  // Other attributes and methods not shown.
  public Customer setName(String name){ 
     this.name = name;
     return this;  // Returns this instance for method chaining with the `name` value set.
  }
}
