1、父工程创建

1.1新建

1.2 父工程pom.xml

<?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.hc.cloud</groupId><artifactId>msb-mall</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><properties><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties>
</project>

2、添加maven依赖

<properties><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><hutool.version>5.8.26</hutool.version><lombok.version>1.18.26</lombok.version><druid.version>1.1.20</druid.version><mybatis.springboot.version>3.0.3</mybatis.springboot.version><mybatis-plus.version>3.5.7</mybatis-plus.version><mysql.version>8.0.33</mysql.version><swagger3.version>2.2.0</swagger3.version><fastjson2.version>2.0.40</fastjson2.version><persistence-api.version>1.0.2</persistence-api.version><spring.boot.test.version>3.1.5</spring.boot.test.version><spring.boot.version>3.2.3</spring.boot.version><spring.cloud.version>2023.0.0</spring.cloud.version><spring.cloud.alibaba.version>2022.0.0.0-RC2</spring.cloud.alibaba.version></properties><repositories><repository><id>alimaven</id><url>https://maven.aliyun.com/repository/public</url></repository><repository><id>mvnrepository</id><url>https://mvnrepository.com/</url></repository><repository><id>nexus</id><url>https://repo.maven.apache.org/maven2</url></repository></repositories><dependencyManagement><dependencies><!--springboot 3.2.0--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>${spring.boot.version}</version><type>pom</type><scope>import</scope></dependency><!--springcloud 2023.0.0--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring.cloud.version}</version><type>pom</type><scope>import</scope></dependency><!--springcloud alibaba 2022.0.0.0-RC2--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring.cloud.alibaba.version}</version><type>pom</type><scope>import</scope></dependency><!--SpringBoot集成mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>${mybatis.springboot.version}</version></dependency><!--Mybatis-plus  --><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-spring-boot3-starter</artifactId><version>${mybatis-plus.version}</version></dependency><!--Mysql数据库驱动8 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><!--SpringBoot集成druid连接池--><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>${druid.version}</version></dependency><!--persistence--><dependency><groupId>javax.persistence</groupId><artifactId>persistence-api</artifactId><version>${persistence-api.version}</version></dependency><!-- fastjson2 --><dependency><groupId>com.alibaba.fastjson2</groupId><artifactId>fastjson2</artifactId><version>${fastjson2.version}</version></dependency><!-- swagger3 调用方式 http://你的主机IP地址:5555/swagger-ui/index.html --><dependency><groupId>org.springdoc</groupId><artifactId>springdoc-openapi-starter-webmvc-ui</artifactId><version>${swagger3.version}</version></dependency><!--hutool--><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>${hutool.version}</version></dependency><!--lombok--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>${lombok.version}</version><optional>true</optional></dependency><!-- spring-boot-starter-test --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><version>${spring.boot.test.version}</version><scope>test</scope></dependency></dependencies></dependencyManagement>

3、项目总体配置

3.1 字符集编码

3.2 注解激活

3.3 maven 配置

3.4 jdk版本设置

3.5 maven 跳过单元检测

        

3.6 povided 设置生效

3.7鼠标滚轮设置

3.8 自动导入依赖设置

4、mysql引入说明

4.1 mysql5

# mysql5.7---JDBC四件套
jdbc.driverClass = com.mysql.jdbc.Driver
jdbc.url= jdbc:mysql://localhost:3306/db2024?useUnicode=true&characterEncoding=UTF-8&useSSL=false
jdbc.user = root
jdbc.password =123456# Maven的POM文件处理
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version>
</dependency>

4.2 mysql8

# mysql8.0---JDBC四件套
jdbc.driverClass = com.mysql.cj.jdbc.Driver
jdbc.url= jdbc:mysql://localhost:3306/db2024?characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8&rewriteBatchedStatements=true&allowPublicKeyRetrieval=true
jdbc.user = root
jdbc.password =123456# Maven的POM
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.11</version>
</dependency>
