When a method or variable is annotated with Lombok annotation, the maven plugin will complain by processing the source generation for JPA. I get this kind of failure in the console logs: symbol: class __ location: class ServiceBaseMessage C:\workspaces\[...]\service\ServiceBaseMessage.java:44: error: cannot find symbol @Getter(onMethod = @__({ @JsonProperty("TYPE") })) How to make the apt-maven-plugin and queryDSL processor for JPA annotations work together with lombok annotations ? This solution worked for me. Add lombok.launch.AnnotationProcessorHider$AnnotationProcessor in your apt-maven

I am using Spring Data JPA with a RDBMS in my project. I have a requirement where I have to fetch a single record from the Database from a table which has the latest date. For this I need to use a limit and order by function OR using sub queries. However, I wished to know if i wish for not to use NamedQuery is there a way I can achieve this using Spring Data JPA and QueryDSL. Shouldn't QueryDslPredicateExecutor.findAll(Predicate predicate, Pageable pageable) do the trick for you? You could hand in a new PageRequest(0, limit) and thus would get back the first limit results. How about using the

I am using QueryDSL with Spring Data JPA in my Java Project and have Generated files using QueryDSL maven plugin to use the QueryDSL Model classes generated by it.

QTransaction qtransaction = QTransaction.transaction; QMachine qmachine = qtransaction.machine; BooleanExpression vendorexp =

I am a newbie in querydsl. I saw two types of querydsl implementations. Is there any differnece? I already developed with com.mysema.query implementation. But I think I went wrong way. Please explain about this. com.querydsl is the root package for Querydsl 4.* and com.mysema.query is the root package for Querydsl 3.*. The background is that Querydsl was initially owned by Mysema , but is now owned and mantained by the Querydsl team . 来源： https://stackoverflow.com/questions/32469814/the-difference-between-com-mysema-query-and-com-querydsl

Querydsl是一个采用API代替拼凑字符串来构造查询语句，可跟 Hibernate 和 JPA 等框架结合使用。网上很多教程都是结合spring JPA框架下使用的教程，本文介绍的是非spring环境下querydsl JPA整合使用。 1、使用eclipse生成jpa实体类，IDEA也能生成同样JPA实体类。 鼠标右键打开JPA Tools工具： 创建数据库链接： 选择那些数据库表需要生成JPA实体类： 关联表生成： 设置实体生成属性： 单个实体属性修改 生成的JPA实体类AdminLog.java package com.test.db.entity; import java.io.Serializable; import javax.persistence.*; import java.util.Date; /** * The persistent class for the admin_log database table. * */ @Entity @Table(name="admin_log") @NamedQuery(name="AdminLog.findAll", query="SELECT a FROM AdminLog a") public class AdminLog implements Serializable { private static
