目录 1.基本步骤 2.Java 实体类 3.集成Mapper 4.Mapper继承tkMabatis的Mapper接口 5.启动类Application或自定义Mybatis配置类上使用@MapperScan注解扫描Mapper接口 6.application.properties配置mapper.xml配置文件的扫描路径 7.常用注解 8.常用方法 1.基本步骤 1. 引入TkMybatis的Maven依赖 2. 实体类的相关配置,@Id,@Table 3. Mapper继承tkMabatis的Mapper接口 4. 启动类Application或自定义Mybatis配置类上使用@MapperScan注解扫描Mapper接口 5. 在application.properties配置文件中,配置mapper.xml文件指定的位置[可选] 6. 使用TkMybatis提供的sql执行方法 7. 如有需要,实现mapper.xml自定义sql语句 PS : 1. TkMybatis默认使用继承Mapper接口中传入的实体类对象去数据库寻找对应的表,因此如果表名与实体类名不满足对应规则时,会报错,这时使用@Table为实体类指定表。(这种对应规则为驼峰命名规则) 2. 使用TkMybatis可以无xml文件实现数据库操作,只需要继承tkMybatis的Mapper接口即可。 3.

Outer joins with ON conditions in JPA

SELECT w.weight_id, w.weight, zc.charge FROM weight w LEFT OUTER JOIN zone_charge zc ON w.weight_id=zc.weight_id AND zc.zone_id=? <------- ORDER BY w.weight ASC The corresponding JPQL query would be like, SELECT w.weightId, w.weight, zc.charge FROM Weight w LEFT JOIN w.zoneChargeSet zc WITH zc.zone.zoneId=:id <------- ORDER BY w.weight I can't reproduce the same with criteria especially WITH zc.zone.zoneId=:id . The following criteria query

How to set default behaviour to Grails' Criteria?

由 匆匆过客 提交于 2020-01-23 19:22:27
问题 What I'd like to do is to set: setReadOnly(true) to every criteria query by default. Is it possible to define default settings that would be applied to every single criteria query that is executed in the application? P.S. I would possibly want to add the following as criteria defaults also but am unsure, whether they would have any additional effect to setReadOnly: setCacheMode(CacheMode.IGNORE) setFlushMode(FlushMode.MANUAL) 回答1: Done some digging and found this for you: http://www

Convert date to string in Hibernate Criteria

由 别说谁变了你拦得住时间么 提交于 2020-01-21 12:14:49
问题 Is it possible to perform a request that checks the string representation of a Date instance. For example Restrictions.like("dateField", "%12%") to retrieve dates that either have String 12 in day or 12 in month or 12 in year where "dateField" is an instance of java.util.Date Thanks 回答1: I had the same problem and here's what I did: First, I created my own Criterion implementation: public class DateLikeExpression implements Criterion { private static final long serialVersionUID = 1L; private

Grails/Groovy: Modify a “query” closure at runtime

由 耗尽温柔 提交于 2020-01-16 04:58:08
问题 In a gorm domain class, I can do def q = { property1{ eq('attr', 0) } } MyDomainClass.list(q) How could I modify the closure 'q' (or create a new closure that would contain the restrictions that closure 'q' has) at runtime so for example I could add another property restriction? More details Actually my problem is how to create combined criteria in a Domain Class Hierarchy. class Parent{ int pAttr static def getCriteria(){ def dummyParentCriteria = { eq('pAttr', 0) } } } class Child extends
