工程名称；
选择字符编码：utf-8

file -> Settings -> Editor -> File Encodings
注解生效激活

file -> Settings -> Builder -> Annotation Processors
Java编译版本

file -> Settings -> Builder -> Java Compiler

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>com.ken.spring-cloud</groupId>

  <artifactId>cloud</artifactId>

  <version>1.0-SNAPSHOT</version>

  <packaging>pom</packaging>	#打包方式修改

  <properties>

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    <maven.compiler.source>11</maven.compiler.source>

    <maven.compiler.target>11</maven.compiler.target>

    <junit.version>4.12</junit.version>

    <log4j.version>1.2.17</log4j.version>

    <lombok.version>1.16.18</lombok.version>

    <mysql.version>5.1.47</mysql.version>

    <druid.version>1.1.16</druid.version>

    <mybatis.spring.boot.version>1.3.0</mybatis.spring.boot.version>

  </properties>
