java.net.UnknownHostException: mybatis.org百搜不得解

Question

报错：java.net.UnknownHostException: mybatis.org

项目是mybatis3和spring3整合的项目，能上网时运行正常，不能上网时就会报这个错。单独运行测试案例时不会报错，只要在服务器上运行就会报错。我试过在xml catalog中配置mybatis-3-config.dtd，仍然不起作用。 请大家帮忙:

配置文件：

mybatis-config.xml header

<?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">

Answer 2

删了起不来，试过了。现在有一种办法能在断网的环境下启动，就是把DTD文件配置在HEADER中，而且必须配绝对路径，是不是和包的版本有关，不过我这都是 3

<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"C:UserspeterDesktop/mybatis-3-config.dtd">

Answer 3

干脆把头里那些删了试试？
