error between mybatis 3.0.5 and newer version (>3.1.0)

[matpil]

Hi,

I'd like to update mybatis (and mybatis-spring) version from 3.0.5 to the last 3.2.2 but I've an issue on my working mapper.

error is:

....

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.mybatis.spring.mapper.MapperScannerConfigurer#0' defined in class path resource [com/myApp/context/service-context.xml]:

I've try to update with jar version 3.1.1, 3.2.0, 3.2.2, and 3.2.3-SNAPSHOT.

Is new version not backward compatible???

thanks in advance

It is backward compatible. This can be a bug in newer version or you can have a wrong mapping that new versions are able to detect and olders don't.

Have a look at __myAppMapper and that "value" to see if there is something wrong with it.

Thanks for your reply!

The result map that I use is:

<resultMap id="RateDaFatturareMap" type="java.util.Map">

   <result column="METODO" jdbcType="VARCHAR" property="key" />

  <collection column="IMF.CD_ORDINE" 

      property="value"

      javaType="java.util.List"

      ofType="String">

     <result column="IBAN" jdbcType="VARCHAR" property="value" />

  </collection>

</resultMap>

and with myBatis 3.0.5 works fine.

It could be a bug in newer version?

I will try to reproduce it and tell you something.

The point is that 3.2.2 is trying to discover the type "value" of the class "String" and it happens that String has a property named "value" of the type char[] and there is not a default handler for it so 3.2.2 points that there is something wrong here. Probably 3.0 is just ignoring this and works by chance.

Note that there is not any property named "value" in your objects so the right mapping is:

It works like this:

  <collection column="IMF.CD_ORDINE" 

      property="value"

      javaType="java.util.List"

      ofType="String">

     <result column="IBAN" jdbcType="VARCHAR"  />

  </collection>
