用于java的DAO生成器 [英] DAO generator for java

问题描述

我正在为java搜索免费且简单的DAO生成器（它需要从db表/视图创建实体/ bens并生成基本的CRUD代码）。目前，我使用的DAO4J缺少视图映射等功能。我知道有像Hibernate这样的框架，但我不需要这样强大的框架。

I'm searching for free and simple DAO generator for java (it needs to create entities/bens from db tables/views and generate basic CRUD code). Currently, I`m using DAO4J which lacks some functionality like views mapping. I know that there are frameworks like Hibernate but I dont need such robust framework.

这个框架应该做的一些事情：

Some things this framework should have to do:

• 生成CRUD操作标准SQL查询而非编译时类型安全查询


• 没有像hibernate这样的会话概念


• 不会自动关闭连接


• JDBC连接可以通过代码配置

• Generate CRUD operations with standard SQL queries and not compile-time typesafe queries
• Doesn't have session concept like hibernate
• Will not automatically close connection
• JDBC Connection can be configured through code

推荐答案

这些都不是完美的比赛，但两者都以自己的方式摇滚：

None of these are perfect matches, but both rock, in their own individual way:

1. Spring Roo 为您生成DAO，Web
   控制器等。


2. QueryDSL 自动从数据库表中创建对象，并提供具有编译时安全性的面向对象查询语法。

1. Spring Roo generates DAOs, Web Controllers and more for you.
2. QueryDSL automatically creates Objects from your database tables and offers an Object-Oriented query syntax with compile-time safety.

但我会说赢家是 Spring Data 。它提供了对许多不同底层数据存储技术的简单但强大的抽象，并自动为您生成daos。以下是 Spring Data JPA 的演示文稿。 不幸的是，Spring Data尚未在最终版本中发布。

But I'd say the winner is Spring Data. It offers a simple but powerful abstraction over many different underlying data store technologies and generates daos for you automatically. Here's a presentation of Spring Data JPA. Unfortunately Spring Data has not been released in final versions yet.
