Should raw Hibernate annotated POJO's be returned from the Data Access Layer, or Interfaces instead?

问题 I understand separating the data layer objects (DAOs) in their own layer that abstracts the data access logic and data source specifics from service and business layers as outlined in DAO and Service layers (JPA/Hibernate + Spring) and other questions. I have experience creating these layers, but I've always used either raw JDBC or similar lower level ways of interfacing with the DB (such as Spring's SimpleJDBC), and am new to Hibernate. My question comes in that in raw JDBC or other ways

Hibernate derived property with xml mapping

萝らか妹 提交于 2019-12-01 19:05:48
I have a Detectable class with a Revisions set, which are Hibernate managed POJOs. I'm also mapping my entities using hbm.xml files. When user goes to Detectable management screen, I want him to see Detectable data into a table, which will also contain the last Revision done. However the complete set of revisions will only be available accessing the detail page of the detectable. My chance is to show the last revision date which will be loaded separately as an attribute with each Detectable instance. So I have something like that: detectable.hbm.xml <set name="_Revisions" table="trevision"

Pojo to xsd generation

╄→гoц情女王★ 提交于 2019-12-01 03:53:58
Is there a library which could generate a xsd schema from a java class? Google yields lots of results the opposite ( java classes from xsd ). JAXB 2.0 allows you to create a XML schema from an annotated Java class. You'll find some examples at the AMIS blog and at the JavaPassion site . JiBX does this The schema generator tool first reads one or more JiBX binding definitions and then uses reflection to interpret the structure of the Java classes referenced in the bindings. By combining the binding definitions with the actual class information the schema generator is able to construct one or

Programming difference between POJO and Bean

醉酒当歌 提交于 2019-11-30 23:51:28
I have the following two classes. Can I say the first one is a POJO class and the second one as a Bean class? 1) POJO class, since it has only getter and setter method, and all the member are declared as private public class POJO { private int id; private String name; public int getId() { return id; } public String getName() { return name; } public void setId() { this.id = id; } public void setName() { this.name = name; } } 2) Bean class - all the member variables are private, has getters and setters and implements Serializable interface public class Bean implements java.io.Serializable {
