Querydsl: 使用 JPA/Hibernate 和 Hibernate Envers 时，扩展 Hibernate Envers DefaultRevisionEntiry 的类的代码生成失败并显示 JPAAnnotationProcessor

创建于 2012-09-28  ·  4评论  ·  资料来源: querydsl/querydsl

我的模型类使用 JPA 的@Entity注释进行注释。 除了扩展 Hibernate Envers 的 DefaultRevisionEntity 的类之外，所有其他类都可以正常生成。 在mvn clean test期间代码生成失败并出现以下错误

/.../target/generated-sources/java/.../QRevision.java:[23,37] cannot find symbol
symbol  : class QDefaultRevisionEntity
location: package org.hibernate.envers
/.../target/generated-sources/java/.../QRevision.java:[23,94] cannot find symbol
symbol  : class QDefaultRevisionEntity
location: package org.hibernate.envers
修订版.java：
import javax.persistence.Entity;

import org.hibernate.envers.DefaultRevisionEntity;
import org.hibernate.envers.RevisionEntity;

<strong i="11">@Entity</strong>
@RevisionEntity(CustomRevisionListener.class)
public class Revision extends DefaultRevisionEntity {
    // Fields are irrelevant

对外部注释实体类型的引用应该在类路径中具有可用的 Q 类型。

要强制生成 QDefaultRevisionEntity，您可以将以下注释添加到 package-info.java 文件中

@QueryEntities({DefaultRevisionEntity.class})
package com.example.domain;

import org.hibernate.envers.DefaultRevisionEntity;
import com.mysema.query.annotations.QueryEntities;

这将为您提供具有以下内容的 QDefaultRevisionEntity.java

package org.hibernate.envers;

import static com.mysema.query.types.PathMetadataFactory.*;

import com.mysema.query.types.*;
import com.mysema.query.types.path.*;

import javax.annotation.Generated;


/**
 * QDefaultRevisionEntity is a Querydsl query type for DefaultRevisionEntity
 */
@Generated("com.mysema.query.codegen.EmbeddableSerializer")
public class QDefaultRevisionEntity extends BeanPath<DefaultRevisionEntity> {

    private static final long serialVersionUID = -546101328;

    public static final QDefaultRevisionEntity defaultRevisionEntity = new QDefaultRevisionEntity("defaultRevisionEntity");

    public final NumberPath<Integer> id = createNumber("id", Integer.class);

    public final DateTimePath<java.util.Date> revisionDate = createDateTime("revisionDate", java.util.Date.class);

    public final NumberPath<Long> timestamp = createNumber("timestamp", Long.class);

    public QDefaultRevisionEntity(String variable) {
        super(DefaultRevisionEntity.class, forVariable(variable));
    }

    public QDefaultRevisionEntity(Path<? extends DefaultRevisionEntity> path) {
        super(path.getType(), path.getMetadata());
    }

    public QDefaultRevisionEntity(PathMetadata<?> metadata) {
        super(DefaultRevisionEntity.class, metadata);
    }

}

哇 ！ 真的行 ！ 谢谢@timowest

我的代码上只有@Entity ，它仍然有效。
