Duplicate annotation error - but where?

java jpa annotations

Solution 1

I would be incredible surprised if the @NamedQueries is a issue, the name suggests that it should be a list/array of @NamedQuery items.

Try:

@Column(name = "name", length = 128)
private String name;

Seeing as you are confidant that you don't actually have @size repeated, maybe we should be looking at overlap of function, the @Column annotation contains the same functionality, maybe this could be causing a conflict.

Solution 2

I get the same issue but my problem was comming from pom.xml file. I had there two jpa dependencies 

<dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
        <version>2.5.2</version>
        <scope>provided</scope>
</dependency>

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

I deleted the first one and this solved my problem. Sorry for my english level

Solution 3

The answers in here already discuss the possible solutions to solve this problem so I will focus on sharing my findings on the root cause of the issue.

I experienced this issue after generating entities using Netbeans 8.2 with the Create Persistence Unit box ticked. Doing this procedure causes two dependencies to be added to your project in the pom.xml namely org.eclipse.persistence.jpa.modelgen.processor and eclipselink.

These EclipseLink dependencies added to my project had a bug issue that was reported :

... @Column annotation seem to suddenly not be compatible with other annotations anymore.

As a result of this bug, you therefore would not be able to use @Column annotation with either @NotNull or @Size.

Solution 4

In the pom.xml file, delete:

<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
    <version>2.5.2</version>
    <scope>provided</scope>
</dependency>

Solution 5

this error exists at IDE level. For example on field userName annoted as:

@NotNull
@Size(max = 255)
@Column(name = "user_id", nullable = false, length = 255)
private String userName;

will throw the duplicate error triggered by @Size and length = 255 and most probably if the size validity of user_id is not set in the database; and @NotNull and nullable = false also most probably if the not nullable constraint hasn't been set in the DB. Note that by default NetBeans validates your String fields to length 255 on Entity autogeneration if the validity doesn't originate from the DB. Correct the error thrown by:

@Column(name = "user_id", nullable = false, length = 255)
private String userName;

OR

@NotNull
@Size(max = 255)
@Column(name = "user_id")
private String userName;

Edit: For spring-boot users, error could be common if you have both eclipse-link and spring-data-jpa defined in your pom.xml. exclude eclipse-link in your dependencies

    Briefly, first - I get this Exception message:

    serverError: class javax.faces.el.EvaluationException Duplicate annotation for class: interface javax.validation.constraints.Size: @javax.validation.constraints.Size(groups=[], min=0, message={javax.validation.constraints.Size.message}, payload=[], max=128)

    My code consist of 1 Entity class for a table, an EJB, a 'business class' and a JSF page; the exception happens when I call EntityManager.merge(). There is only 1 annotation with 'max = 128' in it:

    @Size(max = 128)
@Column(name = "name")
private String name;

    The only place with duplicated annotations is:

    @Entity
@Table(name = "attributes", schema = "office_db")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM Attributes a"),
    @NamedQuery(name = "Attributes.findById", query = "SELECT a FROM Attributes a WHERE a.id = :id"),
    @NamedQuery(name = "Attributes.findByName", query = "SELECT a FROM Attributes a WHERE a.name = :name"),
    @NamedQuery(name = "Attributes.findByType", query = "SELECT a FROM Attributes a where a.type.id = :type")
})

    but I think that should be legit as it has been generated by Netbeans 8.2 from the database table.

    Now some more details. First the table:

    mysql> show create table attributes\G
*************************** 1. row ***************************
       Table: attributes
Create Table: CREATE TABLE `attributes` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `parent` int(11) DEFAULT NULL,
  `type` int(11) DEFAULT NULL,
  `name` varchar(128) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `parent_ix` (`parent`),
  KEY `type_ix` (`type`),
  CONSTRAINT `attributes_parent_fk` FOREIGN KEY (`parent`) REFERENCES `attributes` (`id`),
  CONSTRAINT `attributes_type_fk` FOREIGN KEY (`type`) REFERENCES `attributes` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1301 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
1 row in set (0.03 sec)

    Next the Entity class:

    import (...stuff...)

@Entity
@Table(name = "attributes")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM     Attributes a"),

    @NamedQuery(name = "Attributes.findByName", query = "SELECT a FROM Attributes a WHERE a.name = :name"),
    @NamedQuery(name = "Attributes.findByType", query = "SELECT a FROM Attributes a where a.type.id = :type")
})

    @Override

    The EJB or session class:

    That actually worked! Amazing - thx a lot. I can't vote your answer up, but I ticked it as an answer - I'd really like to know why it makes a difference, though.
