排查

在服务启动时，通过netstat 可发现有个tcp一直在创建连接

netstat -ant | grep -E 'SYN_SENT|SYN_RECV'

并且通过上面的日志发现是freight-driver-mall-mybatis.xml文件
故可定位是该文件中的有个ip不通

<?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>

即http://mybatis.org/dtd/mybatis-3-config.dtd 在节点上ping该域名是不通的

解决方案

方案一解决mybatis.org网络问题

方案二调整为org/apache/ibatis/builder/xml/mybatis-3-mapper.dtd

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "org/apache/ibatis/builder/xml/mybatis-3-mapper.dtd">
