SpringDataJPA 是 Spring Data 的一个子项目，通过提供基于 JPA 的 Repository 极大的减少了 JPA 作为数据访问方案的代码量，你仅仅需要编写一个接口集成下 SpringDataJPA 内部定义的接口即可完成简单的 CRUD 操作，理论的东西不做多解释，下面我们开始讲解SpringBoot 构建项目 我们使用IntelliJ IDEA工具构建一个SpringBoot项目，预先导入Web、MySQL、JPA依赖，我们简单使用一个RestController来实现JPA的配置，之前也有讲解JPA的简单使用，今天详细的讲解下具体的细节性的内容，项目结构如下图1所示： 图1 使用Druid数据源 我们使用之前章节的配置，加入Druid数据源配置到我们的项目中，复制 第四章：使用Druid作为SpringBoot项目数据源（添加监控） 项目中的application.yml配置文件到我们项目resources下，并且修改pom.xml添加Druid数据源依赖，如下图2所示： 图2 application.yml配置文件内容如下图3所示（具体代码请到码云下载地址： git.oschina.net/jnyqy/lessons ）： 图3 使用JpaRepository 我们在配置使用JpaRepository之前需要对应我们的测试表添加实体映射

Is it possible to compare two fields from different types on a Query DSL?

问题 I'm new to ElasticSearch and I'm struggling with this question. Basically what I want to do is sort of like this (SQL Example): SELECT A.id FROM TableA A, TableB B WHERE A.id = B.id; I want a Query that returns all of the info from TableA, but only if the id from TableA is equal to an id from TableB. I've read a lot of Query Filter fields and I think I might use the Term Field but I'm not sure how. Thanks in advance! 回答1: This answer was given by Adrien Grand on a ElasticSearch group: This
