Overview

Atoti Limits provides several objects out-of-the-box that are managed by the default EntityManager. Each of these objects is defined as a JPA entity using the @Entity and @Table annotations. The default entity classes are:
Managed ObjectEntity Class
Limit Structurescom.activeviam.limits.model.jpa.LimitStructureEntity
Limitscom.activeviam.limits.model.jpa.LimitEntity
Incidentscom.activeviam.limits.model.jpa.IncidentEntity
In some scenarios you may want to override the default managed objects, for example: To customize these entities, you’ll need to override the default entity classes. The following steps outline how to correctly configure your custom entity classes:

1. Copy the existing entity class to your project with the same class and package names

It is critical that the class and package names remain the same so that the EntityManager recognizes your custom entity class as an override of the default entity class and doesn’t treat it as a new entity. For example, to customize the LimitEntity class, you need to create a LimitEntity.java file at the following path in your project:
./<java folder>/com/activeviam/limits/model/jpa/LimitEntity.java
Where <java-folder> is the path from the root of your project to the directory containing your .java files, typically src/main/java.

2. Modify the entity class as needed

Removing or renaming existing fields may break Atoti Limits.
You can now modify the entity class as needed. The following example increases the length of the limit_type field from the default of 255 characters to 4000 and adds a new description field with a length of 1000 characters, all other fields and methods remain unchanged:
@Entity
@Table(name = TABLE_LIMIT)
@Getter
@Setter
@EqualsAndHashCode
public class LimitEntity implements ILimitsApplicationEntity<String>, ILimit {
@Id
@Column(name = COL_LIMIT_ID)
protected String limitId;
@Column(name = COL_LIMIT_STRUCT_ID)
protected String structureId;
@Column(name = COL_START_DATE)
protected LocalDate startDate;
@Column(name = COL_END_DATE)
protected LocalDate endDate;
@Column(name = COL_LIMIT_TYPE, length = 4000) // Increased length from default (255) to 4000
  protected String limitType;
@Column(name = COL_SCOPE, length = 555)
protected String scope;
@Column(name = COL_LIMIT_STATUS)
protected String limitStatus;
@Column(name = COL_SOURCE_LIMIT_ID)
protected String sourceLimitId;
@Column(name = COL_LIMIT_VALUE)
protected double limitValue;
@Column(name = COL_PRECEDENCE)
protected int precedence;
@Column(name = "description", length = 1000) // New field added
  protected String description;
@Override
public String getId() {
return limitId;
}
@Override
public boolean isNew() {
return limitId == null;
}
public Limit toLimit() {
Limit limit =
Limit.builder()
.limitId(limitId)
.structureId(structureId)
.startDate(startDate)
.endDate(endDate)
.limitType(LimitType.valueOf(limitType))
.scope(Scope.fromScopeString(scope))
.limitStatus(limitStatus)
.draftLimit(null)
.draftLimitStatus(limitStatus)
.sourceLimitId(sourceLimitId)
.limitValue(limitValue)
.precedence(precedence)
.build();
if (List.of(EXPIRED.toString(), DELETED.toString()).contains(limitStatus)) {
limit.setAlive(false);
}
return limit;
}
public static LimitEntity fromLimit(Limit limit) {
LimitEntity limitEntity = new LimitEntity();
limitEntity.setLimitId(limit.getLimitId());
limitEntity.setLimitType(limit.getLimitType().toString());
limitEntity.setStructureId(limit.getStructureId());
limitEntity.setStartDate(limit.getStartDate());
limitEntity.setEndDate(limit.getEndDate());
limitEntity.setScope(limit.getScope().toScopeString());
limitEntity.setLimitStatus(limit.getLimitStatus());
limitEntity.setSourceLimitId(limit.getSourceLimitId());
limitEntity.setLimitValue(limit.getLimitValue());
limitEntity.setPrecedence(limit.getPrecedence());
return limitEntity;
}
@Override
public void setID(String id) {
setLimitId(id);
}
}
If you have an existing database and you modify the physical structure of the data in your schema, you may need to migrate the schema in order for your changes to take effect.
The next time you start Atoti Limits, it will use your custom entity class for the Limit managed object. You can verify the change is applied by checking the schema for the limits table in your database to verify that the limit_type column has a length of 4000 and that the new description column exists:
