Apache Olinge OData service throws EdmSimpleTypeException when the column in database is of type TEXT or BLOB


I have made an entity by using JPA in eclipse. The definition of the table in my MySQL is like this:

CREATE TABLE `users` (
  `id` int(255) NOT NULL,
  `name` varchar(255) NOT NULL,
  `photo_content` text CHARACTER SET ascii DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

and the equivalent entity that I generated by JPA is like this:

import java.io.Serializable;
import javax.persistence.*;
import java.util.Set;


/**
 * The persistent class for the users database table.
 * 
 */
@Entity
@Table(name="users")
@NamedQuery(name="User.findAll", query="SELECT u FROM User u")
public class User implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @Column(unique=true, nullable=false)
    private int id;

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

    @Lob
    @Column(name="photo_content")
    private String photoContent;

    //bi-directional many-to-one association to Answer
    @OneToMany(mappedBy="user")
    private Set<Answer> answers;

    //bi-directional many-to-one association to Survey
    @OneToMany(mappedBy="user")
    private Set<Survey> surveys;

    public User() {
    }

    public int getId() {
        return this.id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhotoContent() {
        return this.photoContent;
    }

    public void setPhotoContent(String photoContent) {
        this.photoContent = photoContent;
    }

    public Set<Answer> getAnswers() {
        return this.answers;
    }

    public void setAnswers(Set<Answer> answers) {
        this.answers = answers;
    }

    public Answer addAnswer(Answer answer) {
        getAnswers().add(answer);
        answer.setUser(this);

        return answer;
    }

    public Answer removeAnswer(Answer answer) {
        getAnswers().remove(answer);
        answer.setUser(null);

        return answer;
    }

    public Set<Survey> getSurveys() {
        return this.surveys;
    }

    public void setSurveys(Set<Survey> surveys) {
        this.surveys = surveys;
    }

    public Survey addSurvey(Survey survey) {
        getSurveys().add(survey);
        survey.setUser(this);

        return survey;
    }

    public Survey removeSurvey(Survey survey) {
        getSurveys().remove(survey);
        survey.setUser(null);

        return survey;
    }

}

As soon as the column photo_content has some value like this:

and I try to read the Users by OData service I will see the following exception:

<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
<code/>
<message xml:lang="en">Missing message for key 'org.apache.olingo.odata2.api.edm.EdmSimpleTypeException.PROPERTY_VALUE_FACETS_NOT_MATCHED'!</message>
</error>

How can I solve it? I found another post here that in the answer, it has been claimed that this error is because of data type conversion but when it is long string we don't have any type casting!


Solution

  • It is only needed to force olingo to remove length for the attribute. By the above definition for the User entity it will end up with maxLength=255 in the metadata. So when we want to use LongText or Blob or Clob with olingo-jpa we must provide a negative size for the property, then it will assume unlimited size for the property!

        @Lob
        @Column(name="photo_content", length=-1)
        private String photoContent;
