Ubuntu 提示sudo: java: command not found解決辦法

　　ubuntu下運行sudo Java 時提示“sudo: java: command not found”。在網上找了，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就可以運行了，但是改完之后依然無效。

　根據一個大神的指引，應該是修改/etc/sudoers這個文件，　

sudo vim /etc/sudoers

　　顯示內容如下：

#
# 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的路徑。

再次運行 sudo java 就可以使用了。
