mybatis-3-config.dtd 没提示,求大神帮助

今天配这花了一下午，我是根据eclipse 如何引入本地dtd 来搞的，发现没效果，我用的eclipse Mars.2

 <?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

都没效果
