Question about usage and extends using xml files about spring-data-mybatis HOT 4 CLOSED

hi @kopax , thanks for your profound questions.

1. it supports override default delete query for a single entity, you should add your custom mapper when create SqlSessionFactory, and use entity's class name as mapper's namespace , and define a delete statement with id "_deleteById" , because I have judged the statement is exist before creating default query.

if (!isStatementExist("_deleteById")) {
            buildDeleteById(builder);
        }

2. have a look at http://docs.spring.io/spring-data/commons/docs/current/reference/html/#repositories.custom-behaviour-for-all-repositories

if you have further question, you can ask me.

3. tell you a small tip : set "org.springframework.data.mybatis" logger level to debug , you can find the default mapper on the console.

because of poor document now ( I am writing hardly ),
you can hardly find out some features.

So if you can provide me some runnable code , I will resolve your questions more effectively.

1. OK
2. OK
3. Thanks

For 3 could you provide me an example for let's say.

I want to implement a select with a custom "WHERE"

SELECT
...
FROM
...
WHERE 
    us_reg_date between '2000-07-05'
AND
    DATE_ADD('2011-11-10',INTERVAL 1 DAY)

It will be nice to just be able to just define the WHERE part

    <select id="selectStepDay" resultType="com.entityA" parameterType="DATE">
        <include refid="_selectEntityA" /> <!-- if you generate these for your select, it should be reusable isn't it ?-->
        <include refid="_fromEntityA" /> <!-- if you generate these for your select, it should be reusable isn't it ?-->
        WHERE 
          us_reg_date between '2000-07-05'
        AND
          DATE_ADD(#value#,INTERVAL 1 DAY)
    </select>

I think I don't need the resultMap if I use the resultType I assume this will be handled in your module.
I have seen some code in your module that generate a mapping, is it a resultMap and if it is, is it in the globalScope ? Would it be more accurate to use resultMap over resultType ?

If you generate the _selectEntityA in an xml markup <sql id=_select"+perisistentEntity.getClass()+"> and same for _fromEntityA, we might be able to reuse them from the global scope of this entity is it correct ?
this way we could rewrite override it in our own file if we need to. It give's flexibility.

It would be interesting to use the builder for really creating the xml file and see how this could be used with our custom mappers.
