@OneToMany doesn't select join column because of missing join statement

[kopax]

annotation @onetomany doesn't join column

It appear the @onetomany association doesn't work as expected.

version

I am using commit.

This is how I did the join table mapping, in SiteService.java :

@JdbcType(BIGINT)
@OneToMany
@JoinTable(name = "SITE_FUNCTION")
@JoinColumn(name = "SITE_SERVICE_ID")
@NotNull
private List<SiteFunction> siteFunctionList;

Result

Produce an empty array for siteFunctionList

Expected result

Produce an array using database data for siteFunctionList

The select method appear to not add any jointure for this table.

(but @manytoone association seems to work fine so far.)
The xml generated render an empty <sql id="SELECT_CONDITION_INNER"></sql>

What is it use for ?

There is this generated for the mapping by the annotations:

        <collection property="siteFunctionList" ofType="com.domain.security.SiteFunction">
            <id property="id" column="siteFunctionList.id" javaType="java.lang.Long" jdbcType="BIGINT"/>
            <result property="messageId" column="siteFunctionList.messageId" javaType="java.lang.String"
                    jdbcType="VARCHAR"/>
            <result property="name" column="siteFunctionList.name" javaType="java.lang.String" jdbcType="VARCHAR"/>
        </collection>

But nothing for selecting the field.

I also wonder, in this scenario, is there any way for me to just rewrite or add some extra xml in my mappers folder in order to complete/repair the mapping ?

That would be a good information to know.

I have upgraded to spring-boot 1.5.1.RELEASE and now how spring-data-commons 1.13.RELEASE according to #98

I was able to start without my error but it seems the one to many have some "case" and mapping issues.

You have a problem with the usage, and you can see this pr: kopax/spring-data-mybatis-testing#2

this pr include @onetomany , rest projection and extend-xml issues.
