MyBatis iterate hashmap with foreach -


i have small problem mybatis. i'm trying iterate on hashmap seems, mybatis not able it. name of hshmap servicemap. here code of mybatis foreach:

<foreach item="item" index="key" collection="servicemap"  open="(" separator="or" close=")">                 (upper(p.endpoint) upper(#{key})                 ,                 upper(p.endpoint_operation) upper(#item)) </foreach>

the exception is:

org.apache.ibatis.builder.builderexception: error evaluating expression 'servicemap'. return value ({vehicle=register}) not iterable. @ org.apache.ibatis.builder.xml.dynamic.expressionevaluator.evaluateiterable(expressionevaluator.java:59) @ org.apache.ibatis.builder.xml.dynamic.foreachsqlnode.apply(foreachsqlnode.java:51) @ org.apache.ibatis.builder.xml.dynamic.mixedsqlnode.apply(mixedsqlnode.java:29) @ org.apache.ibatis.builder.xml.dynamic.ifsqlnode.apply(ifsqlnode.java:31) @ org.apache.ibatis.builder.xml.dynamic.mixedsqlnode.apply(mixedsqlnode.java:29)

is mybatis not able or did make mistake?

it nice, if can me.

thanks lot! stefan

a hashmap not iterable. you need iterate entryset.

<foreach item="item" index="key" collection="servicemap.entryset"  open="(" separator="or" close=")">             (upper(p.endpoint) upper(#{key})             ,             upper(p.endpoint_operation) upper(#item))
