我已经在Eclipse上安装了Spring Tool Suite(STS 3.9.2),我创建了一个Demo应用程序,但当我将它作为" Spring Boot App"我收到以下错误:
错误:代理抛出异常:java.net.MalformedURLException:本地主机名未知:java.net.UnknownHostException:linux-se15:linux-se15:名称或服务未知
运行此命令会产生以下结果:
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
/ etc / hosts具有以下内容:
from itertools import product
print([x[0] * x[1] for x in product(a, b)])
答案 0 :(得分:3)
问题的原因可能是主机和主机名文件。
hosts
文件应包含以下内容:
127.0.0.1 localhost
127.0.1.1 yourhostname
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
hostname
文件应包含yourhostname
您可以使用sudo nano /etc/hosts
和sudo nano /etc/hostname
修改它们。
