这应该是java最好用的orm之一了

说起orm大家肯定都不会陌生,作者是一个.net菜鸟。并且是在.net繁荣的orm圈子下成长的,所以这次给大家带来的是媲美efcore,freesql,sqlsugar的java的orm.如果你是一位.net转java的开发,或者是一名需要经常和数据库打交道的开发者和作者一样是一名crud仔那么这个orm肯定是你不应该错过的,我愿称之为java最好用的orm之一。

复杂sql一

话不多说来一个复杂sql

java 复制代码

        SELECT
        YEAR(日期) AS 年份，
        MONTH(日期) AS 月份
        SUM(收入) AS 月收入
        FROM
                your_table
        WHERE
        日期 >= CURDATE()- INTERVAL 3 MONTH
        GROUP BY
        年份，月份
        ORDER BY
        年份，月份;

用java的写法写sql,并且函数自适应easy-query支持的所有数据库,切库0成本

List<Draft3<Integer, Integer, Integer>> list = easyEntityQuery.queryable(BlogEntity.class)
          .where(o -> o.createTime().gt(o._now().plusMonths(-3))) //WHERE 日期 >= CURDATE()- INTERVAL 3 MONTH
          .groupBy(o -> GroupKeys.TABLE1.of(o.createTime().year(), o.createTime().month()))//GROUP BY 年份，月份
          .orderBy(o -> {
              o.key1().asc();  // ORDER BY 年份，月份;
              o.key2().asc();
          }).selectDraft(o -> Select.draft( //采用草稿类型
                  o.key1(), //YEAR(日期) AS 年份，
                  o.key2(), //MONTH(日期) AS 月份
                  o.sum(o.group().star())  //SUM(收入) AS 月收入
          )).toList();


==> Preparing: SELECT YEAR(t.`create_time`) AS `value1`,MONTH(t.`create_time`) AS `value2`,SUM(t.`star`) AS `value3` FROM `t_blog` t WHERE t.`deleted` = ? AND  t.`create_time` > date_add(NOW(), interval (?) month) GROUP BY YEAR(t.`create_time`),MONTH(t.`create_time`) ORDER BY YEAR(t.`create_time`) ASC,MONTH(t.`create_time`) ASC
==> Parameters: false(Boolean),-3(Integer)
<== Time Elapsed: 4(ms)
<== Total: 0

复杂sql二

java 复制代码

select a.id,a.name
from table a
where (select count(*) as num from table b where b.box_id=a.id ) = 0

//条件里面不直接使用列

        List<Draft2<String, String>> list = easyEntityQuery.queryable(BlogEntity.class)
                .where(o -> {

                    Query<Long> longQuery = easyEntityQuery.queryable(Topic.class)
                            .where(x -> x.id().eq(o.id())).selectCount();//创建子查询的count然后和0常量进行比较

                    o.SQLParameter().valueOf(0L)
                            .eq(longQuery);
                }).selectDraft(o -> Select.draft(
                        o.id(),
                        o.url()
                )).toList();

==> Preparing: SELECT t.`id` AS `value1`,t.`url` AS `value2` FROM `t_blog` t WHERE t.`deleted` = ? AND ? = (SELECT COUNT(*) FROM `t_topic` t1 WHERE t1.`id` = t.`id`)
==> Parameters: false(Boolean),0(Long)

复杂sql三

java 复制代码

//select 查询子表联结
select a,b,c,(select count(*) from a t1 where t.id=b.id) as xx from b


List<Draft3<String, String, Long>> list = easyEntityQuery.queryable(BlogEntity.class)
                .where(o -> {
                    o.id().eq("123");
                }).selectDraft(o -> Select.draft(
                        o.id(),
                        o.url(),
                        o.subQuery(() -> easyEntityQuery.queryable(Topic.class).where(x -> x.id().eq(o.id())).selectCount())
                )).toList();

==> Preparing: SELECT t.`id` AS `value1`,t.`url` AS `value2`,(SELECT COUNT(*) FROM `t_topic` t1 WHERE t1.`id` = t.`id`) AS `value3` FROM `t_blog` t WHERE t.`deleted` = ? AND t.`id` = ?
==> Parameters: false(Boolean),123(String)

可能会有人说这不就是拼sql吗，对的你没有说错就是但是这是强类型的并且是支持所有库的,还有一点jpa你说无法控制sql你不想用,我这个框架完全自主控制sql支持强类型我想你应该没有拒绝的理由。

单表

强类型

因为topicType为枚举类型所以后续的操作都用枚举类型并且有智能提示如果使用其他类型ide会进行报错无法编译通过

group感知

因为group后无法对结果进行展开所以需要有group感知

java 复制代码

                    r.score().set(g.sum(g.group().t2.score()));//因为是join了一张表所以g.group里面其实是tuple2里面有t1和t2两张表
                }))

==> Preparing: SELECT t1.`id`,SUM(t1.`score`) AS `score` FROM `t_topic` t INNER JOIN `t_blog` t1 ON t1.`deleted` = ? AND t.`id` = t1.`id` WHERE t1.`title` IS NOT NULL GROUP BY t1.`id`
==> Parameters: false(Boolean)
<== Time Elapsed: 5(ms)

匿名类型平替

无需定义别名可以直接返回并且拥有强类型,可以作为匿名表继续查询无需定义中间表

java 复制代码

之前看到有人发过.net的orm语法实现，这次我们通过模拟那个作者的orm语法来看看easy-query和其相差多少

c# 复制代码

var query = rep.GetLambdaQuery().Take(100);
var join = query.Select(b => new { a1 = b.Id, a2 = b.F_String }).Join<TestEntityItem>((a, b) => a.a1 == b.TestEntityId);//第一次关联
varjoin2 = join.Select((a, b) => new { a3 = a.a1, a4 = b.Name })
      .Join<TestEntity>((a, b) => a.a3 == b.Id);//第二次关联
  join2.Select((a, b) => new
  {
      a.a4,
      b.Id
  });

这个SQL是一个很明显的匿名sql之间的join处理,一眼看过去基本就大致猜到具体的sql含义所以在表达式这方面其实还是很容易只晓得

sql 复制代码

select 
  t4.[a4], 
  t1.[Id] 
from 
  (
    select 
      t2.[a1] as a3, 
      t3.[Name] as a4 
    from 
      (
        select 
          t1.[Id] as a1, 
          t1.[F_String] as a2 
        from 
          [TestEntity] t1 
        LIMIT 0, 100
      ) t2 
      Inner join [TestEntityItem] t3 on t2.a1 = t3.[TestEntityId]
  ) t4 
  Inner join [TestEntity] t1 on t4.a3 = t1.[Id]

java 复制代码

//selectDraft简单理解为.net的匿名类型但是在java这边没有匿名类型所以通过一种草稿类型来对应可以防止简单功能需要重新定义类本质是元祖tuple1-10
    EntityQueryable<TopicProxy, Topic> query = easyEntityQuery.queryable(Topic.class).limit(100);

    EntityQueryable2<Draft2Proxy<String, Integer>, Draft2<String, Integer>, BlogEntityProxy, BlogEntity> join = query.selectDraft(o -> Select.draft(o.id(), o.stars()))
            .leftJoin(BlogEntity.class, (t, t1) -> t.value1().eq(t1.id()));
    EntityQueryable2<Draft2Proxy<String, String>, Draft2<String, String>, BlogEntityProxy, BlogEntity> join2 = join.selectDraft((a, b) -> Select.draft(a.value1(), b.url()))
            .innerJoin(BlogEntity.class, (t, t1) -> t.value2().eq(t1.id()));

    List<Draft2<String, String>> list = join2.selectDraft((a, b) -> Select.draft(a.value1(), b.url())).toList();

//我们把局部变量去掉

            List<Draft2<String, String>> list = easyEntityQuery.queryable(Topic.class).limit(100)
                    .selectDraft(o -> Select.draft(o.id(), o.stars()))
                    .leftJoin(BlogEntity.class, (t, t1) -> t.value1().eq(t1.id()))
                    .selectDraft((a, b) -> Select.draft(a.value1(), b.url()))
                    .innerJoin(BlogEntity.class, (t, t1) -> t.value2().eq(t1.id()))
                    .selectDraft((a, b) -> Select.draft(a.value1(), b.url())).toList();

或许你是一位java原住民,或许你是一位c#开发,在java语言贫瘠的时候我相信一款优雅的orm能够让你在编写crud的时候放松神经不需要去考虑mybatis这种sql模版带来的心智负担,因为mybatis把所有问题都抛给了用户所以你们一直觉得mybatis好,其实是你们被mybatis调教的好,因为一个框架只要提供的功能足够少那么他需要维护的就足够少,出问题也会足够少,所以你拿诺基亚半个月不需要充电和2024年的智能机一天一冲比较哪个优秀我觉得你应该是赢了

最后

可能有很多小伙伴会推荐我jpa或者jooq我想说如果我没能力那么我可能会选择他们,如果他们支持国产数据库我可能会选择他们,但是你我更愿意推荐easy-query因为我会聆听开发者的声音起码你叫的动我,我是一个在crud混的菜鸟开发,crud的困难，orm的困难必须是一个混迹在业务开发的程序员才能开发出来的好框架，在没开发出这个api的时候已经有很多小伙伴使用lambda的api进行了开发反向非常不错，期待您的使用。
