Ubuntu 提示sudo: java: command not found解决办法

ubuntu下运行sudo Java 时提示“sudo: java: command not found”。在网上找了，其中很多方法都提示要修改/etc/profile的配置，或是修改/etc/environment的配置。配置完sudo java就可以运行了，但是改完之后依然无效。

　根据一个大神的指引，应该是修改/etc/sudoers这个文件，　

1	sudo vim /etc/sudoers

　　显示内容如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

# # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults    env_reset Defaults    mail_badpass Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/usr/java/jdk1.8.0_131/bin"   # Host alias specification   # User alias specification   # Cmnd alias specification   # User privilege specification root    ALL=(ALL:ALL) ALL   # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL   # Allow members of group sudo to execute any command %sudo   ALL=(ALL:ALL) ALL   # See sudoers(5) for more information on "#include" directives:   #includedir /etc/sudoers.d

在Defaults secure_path 中添加Java的路径。

完事好像不用执行source /etc/sudoers

再次运行 sudo java 就可以使用了。
