问题 I went back to programming my old program https://github.com/JonkiPro/REST-Web-Services. I've updated Spring Boot from version 15.6 to version 2.0.0. I have encountered many problems with compilation, but I can not deal with one. Well, during compilation, he throws me in the console 2018-03-18 21:54:53.339 ERROR 3220 --- [ost-startStop-1] com.zaxxer.hikari.HikariConfig : HikariPool-1 - jdbcUrl is required with driverClassName. 2018-03-18 21:54:55.392 INFO 3220 --- [ost-startStop-1] j

问题 I have the following design: For reference, I'm only posting the SimpleGame entity: @Entity @Table(name = "\"SimpleGames\"") @NamedQuery(name = SimpleGame.FIND_ALL, query = "SELECT ga FROM SimpleGame ga") @NamedQuery(name = SimpleGame.FIND_ALL_JOIN_SCORES_GROUP_BY_GAME_ID, query = "SELECT ga FROM SimpleGame ga JOIN ga.simpleScores sc GROUP BY ga.id") @NamedEntityGraph(name = SimpleGame.FETCH_SCORES, attributeNodes = {@NamedAttributeNode("simpleScores")}) public class SimpleGame implements

问题 I would like use Entity Graphs in EclipseLink and GlassFish. @Entity @NamedQueries({ @NamedQuery(name = "invoice.all", query = "SELECT i FROM Invoice i")}) @NamedEntityGraph(name = "graph.invoice", attributeNodes = {@NamedAttributeNode("invoiceNum")}) @Table(name = "INVOICE") public class Invoice implements Serializable { private int id; private String bizonylatSzam; ... } EntityManager em = getEntityManagerFactory().createEntityManager(); EntityGraph eg = em.createEntityGraph("graph.invoice"

问题 I have an User Entity class that I'm trying to do password hashing for. I thought that the easiest way to do this would be to create a password field annotated with @Transient and a hashed password field that is set just before the object is persisted with a method annotated with @PrePersist and @PreUpdate. So I have something like this: @Transient private String password; private String hashedPassword; @PrePersist @PreUpdate private void hashPassword() { if(password != null) { hashedPassword

问题 I have a Maven-built web-app that uses JPA 2.0 at the back end. The JPA provider is EclipseLink 2.3.2. When I build the project (and it deploys runs successfully) it builds the JPA meta-model in the directory ${basedir}/target/generated-sources/annotations/ Yet the IDE doesn't see the classes defined there. Little red dots with an exclamation point everywhere. Yet I can navigate to those files in the Projects window and open the generated source files. Does this happen to anyone else and does

问题 I'm using EclipseLink. I've a JPQLquery and I want to get the sql String.. Now I'm doing in this way: EJBQueryImpl qi = (EJBQueryImpl)jpqlQuery; String sqlQueryString = qi.getDatabaseQuery().getSQLString(); The problem is that in the sqlQueryString the constant are replaced with ? I've tried to get the values navigating the expressions trees ( getSelectionCriteria() and getHavingCriteria() ) but in this way I loose the type... Do any one ever have a problem like this one? 回答1: Quoted from the

问题 I'm using Postgres database in production and H2 for tests. I want to create a new sequence for an existing table - so in Liquibase I wrote this: <changeSet id="Add sequence for BOOKS" author="library"> <createSequence sequenceName="BOOKS_SEQ" incrementBy="500" startValue="1"/> </changeSet> My Entity looks like this: @Entity @Table(name = "BOOKS") @SequenceGenerator(name = "BOOKS_SEQ", allocationSize = 500) public class Book { @Id @GeneratedValue(generator = "BOOKS_SEQ", strategy =
