Win10下，jdk1.8+tomcat8+mysql8+maven3.6+idea2019 安装配置破解

一. jdk1.8
1.安装
2.环境变量配置
新建JAVA_HOME ：jdk安装路径
新建CLASSPATH：.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
path里添加：%JAVA_HOME%\bin与%JAVA_HOME%\jre\bin这两句
3.验证：cmd里输入javac

二.tomcat8
1.安装
2.配置环境变量
path里添加 tomcat安装路径/bin
3.进入目录，打开startup.bat ,然后打开浏览器，输入网址localhost：//8080，如果出现tomcat，则安装成功。点击shutdown.bat关闭。

三.mysql8
1.安装
2.配置初始化my.ini(在安装目录下新建) ， 新建Data文件夹（在安装目录下新建）
需修改成自己的mysql安装目录以及数据存放目录

3.初始化mysql，以管理员身份运行cmd，进入mysql的bin目录，
执行mysqld --initialize --console命令，里面有一串密码，需记住
安装mysql服务 mysqld --install 出现service successfully installed 则成功
启动mysql服务 net start mysql 启动成功
4.使用navicat等图形化工具，修改密码
5.注意事项：mysql8版本与之前版本有个很大的区别
mysql8版本

mysql8版本

url：   jdbc:mysql://localhost:3306/***?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true
driver：   com.mysql.cj.jdbc.Driver

四.maven3.6
1.安装
2.步骤

1、新建环境变量MAVEN_HOME值为maven解压缩后的地址，比如我是：C:\Development Environment\apache-maven-3.6.1

2、往path中增加“%MAVEN_HOME%\bin”

3、打开控制台，输入命令mvn -v验证maven环境变量是否配置成功，如果能显示出maven版本则说明成功

配置阿里云镜像源方法：

1、进入maven安装目录下的conf文件夹，比如我是：C:\Development Environment\apache-maven-3.6.1\conf

2、将此目录下的setting.xml复制到文件夹C:\Users\你的用户名\.m2文件夹下面（如果没有.m2的话就新建一个）。我复制完成后该文件的地址是：
	C:\Users\TusuZer\.m2\settings.xml

3、在.m2下打开setting.xml找到其中的标签，并往标签中增加如下内容并保存即可（此操作的作用是添加一个镜像节点，这样maven下载镜像就不会使用maven默认仓库，而会从我们添加的这个镜像站下载）。

五.idea2019

1、 安装软件
2.将JetbrainsCrack-4.2-release-enc.jar复制到idea安装目录下的bin文件夹下
3.将 -javaagent:3步骤中的jar包完整路径 添加到下列两个文件内容的末尾
idea.exe.vmoptions
idea64.exe.vmoptions
4.打开idea，选择第二种验证方式，输入下列代码
