IntelliJ IDEA 🚀 ​

前言 💡 ​

在开始开发前，先统一 IDE 配置，便于格式化与代码评审。本文聚焦 IntelliJ IDEA 的常用设置与推荐插件，配合简洁说明和适当 emoji，帮助你快速落地、保持一致。🙂

idea64.exe.vmoptions 🧠 ​

-Xms ​

最小堆大小

-Xmx ​

最大堆大小

-XX:CICompilerCount ​

同步编译线程数量

-XX:ReservedCodeCacheSize ​

代码缓存大小

-XX:SoftRefLRUPolicyMSPerMB ​

反编译软引用回收大小

idea.properties 📄 ​

idea.cycle.buffer.size ​

控制台日志缓存滚动大小

推荐配置 ⚙️ ​

Editor -> General ✨ ​

Mouse Control ​

（非必须）Change font size with Ctrl+Mouse Wheel in Active editor or All editors

具体含义：ℹ️ 是否可以通过Ctrl+Mouse（鼠标滚轮）进行放大或缩小字体

建议配置：✅ 根据个人喜好配置

AutoImport ​

Add unambiguous imports on the fl

具体含义：ℹ️ 当使用到类时是否自动导包（如出现多个包路径由开发者自行选择）

建议配置：✅ 打开，以便于开发

Optimize imports on the fl

具体含义：ℹ️ 当没有使用到类时是否删除导包

建议配置：✅ 打开，以防止类中存在多个无用的包

Appearance ​

（非必须）show method separators

具体含义：ℹ️ 是否显示方法时添加分隔符

建议配置：✅ 打开，以便于阅读类中的方法

Editor -> Code Style ✍️ ​

Java & SQL -> Mysql, MariaDB ​

具体含义：ℹ️ 设置Java和SQL代码格式以及格式化风格

建议配置：✅ 将下列文件选择对应的进行导入

Editor -> Inspections 🧐 ​

Non recommended 'field' injections

具体含义：ℹ️ 不推荐进行字段方式进行注入

建议配置：✅ 关闭，以防止进入注入Bean的时候提示警告

Serializable class without 'serialVersionUID'

具体含义：ℹ️ 当实现了Serializable的类没有定义serialVersionUID时进行警告

建议配置：✅ 打开，以提示开发者必须指定序列化UID，以防止实体类序列化和反序列异常

Editor -> File and Code Templates ​

这里进行一个特殊说明，建议javadoc标签不要使用自定义的标签，统一使用官方标准的标签，当使用了maven-javadoc-plugin插件时使用自定义标签必须在配置中进行新建该标签，同时使用自定义标签会增加维护成本，也难进行统一。 修改模版时请将作者改为自己的姓名拼音，姓和名的首字母大写。 新建类、方法时自动生成@since标签后需要将版本号修改为当前版本号，意为这个类、方法是从当前版本号开始创建，比如配置为@since v4.0.0，则为这个类、方法是从v4.0.0版本开始的，后续版本修改不需要修改此标签。 常见javadoc标签详细说明请见《附1》。

     | This is a list of mirrors to be used in downloading artifacts from remote repositories.
     |
     | It works like this: a POM may declare a repository to use in resolving certain artifacts.
     | However, this repository may have problems with heavy traffic at times, so people have mirrored
     | it to several places.
     |
     | That repository definition will have a unique id, so we can create a mirror reference for that
     | repository, to be used as an alternate download site. The mirror site will be the preferred
     | server for that repository.
     |-->
    <mirrors>
        <!-- mirror
         | Specifies a repository mirror site to use instead of a given repository. The repository that
         | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
         | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
         |
        <mirror>
          <id>mirrorId</id>
          <mirrorOf>repositoryId</mirrorOf>
          <name>Human Readable Name for this Mirror.</name>
          <url>http://my.repository.com/repo/path</url>
        </mirror>
         -->
        <mirror>
            <id>aliyunmaven</id>
            <mirrorOf>!rdc-releases, !rdc-snapshots, *</mirrorOf>
            <name>阿里云公共仓库</name>

    <!-- profiles
     | This is a list of profiles which can be activated in a variety of ways, and which can modify
     | the build process. Profiles provided in the settings.xml are intended to provide local machine-
     | specific paths and repository locations which allow the build to work in the local environment.
     |
     | For example, if you have an integration testing plugin - like cactus - that needs to know where
     | your Tomcat instance is installed, you can provide a variable here such that the variable is
     | dereferenced during the build process to configure the cactus plugin.
     |
     | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
     | section of this document (settings.xml) - will be discussed later. Another way essentially
     | relies on the detection of a system property, either matching a particular value for the property,
     | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
     | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
     | Finally, the list of active profiles can be specified directly from the command line.
     |
     | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
     |       repositories, plugin repositories, and free-form properties to be used as configuration
     |       variables for plugins in the POM.
     |
     |-->
    <profiles>
        <!-- profile
         | Specifies a set of introductions to the build process, to be activated using one or more of the
         | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
         | or the command line, profiles have to have an ID that is unique.
         |
         | An encouraged best practice for profile identification is to use a consistent naming convention
         | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
         | This will make it more intuitive to understand what the set of introduced profiles is attempting
         | to accomplish, particularly when you only have a list of profile id's for debug.
         |
         | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
        <profile>
          <id>jdk-1.4</id>

          <activation>
            <jdk>1.4</jdk>
          </activation>

          <repositories>
            <repository>

              <layout>default</layout>
              <snapshotPolicy>always</snapshotPolicy>
            </repository>
          </repositories>
        </profile>
        -->
        <profile>
            <id>JDK-1.8</id>
            <activation>
                <activeByDefault>true</activeByDefault>
                <jdk>1.8</jdk>
            </activation>
            <properties>
                <maven.compiler.source>1.8</maven.compiler.source>
                <maven.compiler.target>1.8</maven.compiler.target>
                <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
            </properties>
        </profile>

        <!--
         | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
         | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
         | might hypothetically look like:
         |
         | ...
         | <plugin>
         |   <groupId>org.myco.myplugins</groupId>
         |   <artifactId>myplugin</artifactId>
         |
         |   <configuration>
         |     <tomcatLocation>${tomcatPath}</tomcatLocation>
         |   </configuration>
         | </plugin>
         | ...
         |
         | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
         |       anything, you could just leave off the <value/> inside the activation-property.
         |
        <profile>
          <id>env-dev</id>

          <activation>
            <property>
              <name>target-env</name>
              <value>dev</value>
            </property>
          </activation>

          <properties>
            <tomcatPath>/path/to/tomcat/instance</tomcatPath>
          </properties>
        </profile>
        -->
    </profiles>
