Debian安装Certbot获取SSL证书

安装snapd

# 安装snapd
apt-get update
apt-get install snapd

# 安装 snapd core
snap install core
snap refresh core

通过snapd安装certbot

snap install --classic certbot

# 软链接
ln -s /snap/bin/certbot /usr/bin/certbot

如果遇到无法下载，可能需要翻墙，请给snap设置代理：

sudo snap set system proxy.http=http://127.0.0.1:1081
sudo snap set system proxy.https=http://127.0.0.1:1081

清除SVN版本控制

关于清除SVN版本控制，本人目前是采用如下方法：通过运行一个.bat文件，删除此目录下所有.svn的文件夹包括子目录下的.svn文件夹

简易版

新建一个clean.bat的文件，用记事本打开，写入:

@echo On @Rem 删除SVN版本控制目录 @PROMPT [Com]
@for /r . %%a in (.) do @if exist "%%a\.svn" rd /s /q "%%a\.svn" @Rem for /r . %%a in (.) do @if exist "%%a\.svn" @echo "%%a\.svn"
@echo Mission Completed. @pause

Lombok介绍

Lombok 是一种 Java 实用工具，可用来帮助开发人员消除 Java 的冗长，尤其是对于简单的 Java 对象（POJO）。它通过注释实现这一目的。通过在开发环境中实现 Lombok，开发人员可以节省构建诸如 hashCode() 和 equals() 这样的方法以及以往用来分类各种 accessor 和 mutator 的大量时间。

SpringToolSuite4安装Lombok

下载 lombok.jar

可以通过下面地址进行下载：

https://repo1.maven.org/maven2/org/projectlombok/lombok/1.18.18/lombok-1.18.18.jar

拷贝lombok.jar至STS目录

目录：/Applications/SpringToolSuite4.app/Contents/MacOS

接着需要将lombok-1.18.18.jar重命名为lombok.jar
(下面截图名称没有改，实际操作时，请将lombok-1.18.18.jar改为lombok.jar)

在STS路径运行命令

cd /Applications/SpringToolSuite4.app/Contents/MacOS

java -jar lombok.jar
