If not, how do you manage these situations? 回答1: Definitely you can do that on Abstract classes , and I think it's a good practice in some common cases. Let me give you an example that I'm using in my graph model: @NodeEntity public abstract class BasicNodeEntity implements Serializable { @GraphId private Long nodeId; public Long getNodeId() { return nodeId; } @Override public abstract boolean

JPARepository has only a save method, which does not tell me if it's create or update actually. For example, I insert a simple Object to the database User, which has three fields: firstname and lastname and age: @Entity public class User { private String firstname; private String lastname; //Setters and getters for age omitted, but they are the same as with firstname and lastname. private int age; @Column public String getFirstname() { return

The idea is that each column will be a preselected field in the bean and each row will be a bean in the List. Slide #32 here looks very promising: http://swinglabs.org/docs/presentations/2007/DesktopMatters/beans-binding-talk.pdf However, NetBeans is not very friendly in letting me assign a bean field to a column. I can right-click the JTable and click Bind->Elements and bind it to my List of beans. However, it will not let me specify what goes in each column. The only option is to create the binding

I know it's possible in Jackson when using this combination: 1) Java 8, 2) compile with "-parameters" option, and 3) the parameters names match JSON. But it's also possible in GSON by default without all these restrictions. For example: public class Person { private final String firstName; private final String lastName; private final int age; public Person(String firstName,
