各类依赖导入过慢问题解决方案

后端项目（maven依赖）

1.打开一个项目，打开pom.xml文件

2.在pom.xml文件中右键，找到maven -> create “settings.xml”如果已经有了这个文件则打开open “settings.xml”

3.将该文件的内容替换为如下内容，保存

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
        <mirror>
            <id>alimaven</id>
            <name>aliyun maven</name>
            <url>https://maven.aliyun.com/nexus/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
        </mirror>

        <mirror>
            <id>uk</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>https://uk.maven.org/maven2/</url>
        </mirror>

        <mirror>
            <id>CN</id>
            <name>OSChina Central</name>
            <url>https://maven.oschina.net/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
        </mirror>

        <mirror>
            <id>nexus</id>
            <name>internal nexus repository</name>
            <url>https://repo.maven.apache.org/maven2</url>
            <mirrorOf>central</mirrorOf>
        </mirror>

    </mirrors>
</settings>

4.idea启动加速

需要配置vmoptions文件，此文件在idea的安装目录中,参考如下

-Xms1g
-Xmx2g
-XX:ReservedCodeCacheSize=1g
-XX:+UseG1GC
-XX:SoftRefLRUPolicyMSPerMB=50
-Xverify:none
-ea
-XX:CICompilerCount=2
-Dsun.io.useCanonPrefixCache=false
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
-Dkotlinx.coroutines.debug=off
-Djdk.module.illegalAccess.silent=true
-Dide.no.platform.update=true
-Djdk.attach.allowAttachSelf=true
