Fully executable Jar does not scan typeAlias

[kazuki43zoo]

mybatis-spring-boot 1.0.1 does not scan typeAlias from specified package as follow:

mybatis.type-aliases-package=com.example.model

Specify a type alias in Mapper XML

<!DOCTYPE mapper PUBLIC
        "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.mapper.MessageMapper">
    <select id="findOne" resultType="Message"> <!-- ## Use type alias -->
        SELECT code, message FROM t_message WHERE code = #{code}
    </select>
</mapper>

I've confirmed to fix this issue using mybatis-spring 1.2.5-SNAPSHOT.

How to install the mybatis-spring 1.2.5-SNAPSHOT into local repository.

$ git clone https://github.com/mybatis/spring.git
$ cd spring
$ git checkout 1.2.x
$ mvn install

And i changed a version of mybatis-spring.

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.2.5-SNAPSHOT</version>
</dependency>

Hello!!

[kazuki43zoo]

This issue will fix via mybatis/spring#121.

[emacarron]

Thank you @kazuki43zoo !!

@eddumelendez @kazuki43zoo Just let us know if we need a new release of the spring module to fix this.

[kazuki43zoo]

@eddumelendez , @eddumelendez

I think that spring-mybatis 1.2.5 and mybatis-spring-boot 1.0.2 should release as soon as possible.

[eddumelendez]

Thanks @kazuki43zoo to report this issue

@emacarron I have tested version 1.2.5-SNAPSHOT and it is working fine. Do you think we can perform a release of mybatis-spring? Thanks in advance.

[emacarron]

Of course we can. Let me know if spring-boot is ready for a release and will make both releases asap.

[emacarron]

Ah, sorry, I see there are no changes in spring-boot so we only need a release of the spring module. Lets go then.
