原因：

服务器部署内网，不连网.

mybatis-config.xml配置头为：

<?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">

内网找不到

http://mybatis.org/dtd/mybatis-3-config.dtd

这个dtd文件，先下载下来，然后放到mybatis-config.xml同路径下，然后修改头为：

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

问题解决。
