IDEA乱码之编码转换

reload是关掉当前文件，重新以你要的格式打开文件例如（utf-8），文件无损 convert是直接转换你当前的文件编码，如果没备份，又没有转换成功，你会有损失的

SSL peer shut down incorrectly

编译时出现如下问题 SSL peer shut down incorrectly 或者某些jar包下载不下来，一般是因为墙的原因导致的。这时候我们就需要配置镜像来解决这个问题。（为了提高jar包的下载速度也可以配置）配置的方法就是在根build.gradle中添加镜像仓库，一般我们选择阿里的 http://maven.aliyun.com/nexus/content/groups/public/完整的如下所示

plugins {
    id 'org.springframework.boot' version '2.1.5.RELEASE'
    id 'java'
}

apply plugin: 'io.spring.dependency-management'

group = 'com.moluo'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
//    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

idea激活服务器搭建

本方法仅支持linux系列的操作系统：Debian、Ubuntu、CentOS，不支持WINDOWS系统。 一键搭建代码：

wget --no-check-certificate -O jetbrains.sh https://mengniuge.com/download/shell/jetbrains.sh && chmod +x jetbrains.sh && bash jetbrains.sh

程序运行后，将开启1027激活端口，如果开启了防火墙，则需要放行1027端口。在JetBrains的软件激活过程中， 选择License server，填写http://你的IP:1027即可。其中的IP是你服务器的IP。

注意：本方法无法激活2018.2以上版本的JetBrains
