SpringData Jpa 入门(基本配置)
Spring Data是什么 Spring Data是一个用于简化数据库访问,并支持云服务的开源框架。其主要目标是使得对数据的访问变得方便快捷,并支持map-reduce框架和云计算数据服务。 Spring Data 包含多个子项目: Commons - 提供共享的基础框架,适合各个子项目<em>使用</em>,支持跨数据库持久化 <em>JPA</em> - 简化创建 <em>JPA</em> 数据访问层和跨存储的持久层功能

SpringData整合JPA
Spring 对 <em>JPA</em> 的支持非常强大,开发者只需关心核心业务逻辑的实现代码,无需过多关注 EntityManager 的创建、事务处理等 <em>JPA</em> 相关的处理,这基本上也是作为一个开发框架而言所能做到的极限了。至此,开发者连仅剩的实现持久层业务逻辑的工作都省了,唯一要做的,就只是声明持久层的接口,其他都交给 Spring Data <em>JPA</em> 来帮你完成!

SpringData JPA 中的更新操作遇到问题,请教!
我的项目<em>使用</em>的是SpringMVC+Spring+Hibernate<em>JPA</em>+SpringData<em>JPA</em>,rn增、删、查全都没问题,但是在更新的时候却遇到问题了。rnrn更新的处理流程是这样的:rn1.用户发送更新操作的请求到Controller层,Controller层收集数据绑定到实体对象中(User)rn2.调用Service层方法,把刚刚数据绑定的User对象传递进去rn3.调用Dao层的save方法,保存。rnrn这里有个问题:修改User的信息时,会自动把其中的List所关联的多对多关系删除掉(该属性没有设置级联操作)rnrn我查了查问题,是因为User对象在被执行save时,该对象不是一个受托管的状态(它是被Controller自动绑定填充的对象)所以导致了List集合的数据被删掉。(如果在save之前先find一下把实体查出来,就不会删除List集合的数据了)rnrn但问题是Dao层并不是我自己写的,是由SpringData<em>JPA</em>自动生成的。它只提供了一个save方法,并没有update方法。按理说在执行SpringData的save方法时,它应该能根据实体对象的状态判断是执行<em>JPA</em>的persist()方法还是执行merge()方法,但是这里好像一直都是执行persist()方法,一直都把它当作新建操作来做的。rnrn我看了看别人做的实例,也是这么来写的Controller的实体,直接调用Service,然后调用Dao更新。中间也没有什么其他的操作(比如再find一次),但是别人的都挺好,怎么就我这个有问题呢!rnrn请教啊,这个问题搞了一整天了,头疼死了

<em>mysql</em>的<em>变量</em>,分为4种类型: 1、局部<em>变量</em>: <em>变量</em>名:      生存时间:局部<em>变量</em>一般用在sql语句块中,比如存储过程的begin/end。其作用域仅限于该语句块      定义方式:declare <em>变量</em>名[,<em>变量</em>名2,<em>变量</em>名3...] 类型 [default value];   <em>变量</em>的定义必须写在复合语句的开头,并且在任何其它语句的前面。可以一次声明多个相同类型的<em>变量</em>。

1.定义 SELECT '2017-10-01' INTO @beginDate; SELECT '2017-11-01' INTO @endDate; SELECT * FROM student WHERE birthday @beginDate; 2.从表里面找出结果然后存储起来 SELECT name into @stuName FROM st

有时我们可以定义一个<em>变量</em>来保存特定的值,便于之后<em>使用</em>它。这样的一个<em>变量</em>,我们称为用户<em>变量</em>。 1、在select语句中<em>使用</em>select @value_name:=字段1,字段2 from table where @value_name>1;2、在set语句中<em>使用</em><em>mysql</em>>set @num=1; <em>mysql</em>>select @num;

SpringData 使用@Query注解(四)
虽然我们可以通过关键字来进行查询,这样查询的优点是比较简单,同时看到方法名我们就知道这个方法是来干啥的,缺点是这个方法名比较长,但更大的缺点是它不能实现更复杂的查询。比方说我想整个带子查询的他就搞不定~~~<em>使用</em>@JQuery注解可以自定义JPQL语句以实现更灵活的查询编写测试类我们发现语句是通过了,但是测试并没有通过。改为Integer那么我们该如何传参呢?第一种方式,<em>使用</em>占位符的方式这个时候,参...
关于SpringData JPA 查询数据id全部为0的原因
我们在通过hibernate正向工程生成数据表后,表中的命名规则会将两个单词中间加上 _ 。我们不要随意的更改表明,如果更改,那么我们进行查询时Spring会再次通过正向工程生成我们更改的那一列,这时,如果我们表中有数据的话,正向工程生成的新列会为其附上默认值。我就是更改列id列的列名,然后进行查询时Spring正向工程生成一个新的id列,并为其赋值为0,这是后查询全部信息时查询的就是全部id为0...
mysql的驱动包,适合使用hibernate和jpa
由于以前的MySQL驱动在<em>使用</em>hibernate的时候遇到了一些问题所以希望将这个问题告诉大家,这个驱动在<em>使用</em>过的时候至今没有遇到什么问题
JPA 使用
前言 在还没有接触到Spring之前,我写数据库操作都是徒手写JDBC,各种连接的建立,结果集的处理、连接的释放、异常的处理。虽然自己有了固定的模板,但是还是很繁琐。随后用了spring中JdbcTemplate,spring自动帮我处理了jdbc连接的建立和释放,已经所有可能的异常捕获,我只需要关注的是结果集的处理,这个极大的提高的我开发效率,而且jdbcTemplate 所有的sql都

1、jpa @Query中<em>使用</em>in,需要注意参数一定要是List&amp;lt;&amp;gt;,不然无法查询出数据。   @Query(value = &quot;select * from trade$seek_purchase_offer where sp_id in (:spIds) and of_enuu = :enUu&quot;, nativeQuery = true) List&amp;lt;SeekPurchaseO...
