        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

二、创建模块guigu-common

1、创建Maven模块

在srb下创建普通maven模块

Group：com.atguigu

Artifact：guigu-common

2、配置pom

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!--lombok用来简化实体类：需要安装lombok插件-->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

三、创建模块service-base

1、创建Maven模块

在srb下创建普通maven模块

Group：com.atguigu

Artifact：service-base

2、配置pom

注意：依赖guigu-common

<dependencies>
    <dependency>
        <groupId>com.atguigu</groupId>
        <artifactId>guigu-common</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <!--swagger-->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
    </dependency>
</dependencies>

四、创建模块service-core

Group：com.atguigu

Artifact：service-core

2、配置pom

注意：依赖service-base

<dependencies>
    <dependency>
        <groupId>com.atguigu</groupId>

        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <!--mysql-->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <!--mybatis-plus-->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
    </dependency>
    <!--mybatis-plus 代码生成器-->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-generator</artifactId>
    </dependency>
    <!-- Mybatis Plus 代码生成器模板引擎,  -->
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
    </dependency>
</dependencies>

五、代码生成器

1、创建数据库

创建数据库srb_core

并执行sql脚本初始化数据结构和数据

2、创建代码生成器

在test目录中创建测试用例，并执行

public class CodeGenerator {
    @Test
    public void genCode() {
        // 1、创建代码生成器
        AutoGenerator mpg = new AutoGenerator();
        // 2、全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/class="lazy" data-src/main/java");
        gc.setAuthor("Helen");
        gc.setOpen(false); //生成后是否打开资源管理器
        gc.setServiceName("%sService");	//去掉Service接口的首字母I
        gc.setIdType(IdType.AUTO); //主键策略
        gc.setSwagger2(true);//开启Swagger2模式
        mpg.setGlobalConfig(gc);
        // 3、数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/srb_core?serverTimezone=GMT%2B8&characterEncoding=utf-8");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("123456");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);
        // 4、包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.atguigu.srb.core");
        pc.setEntity("pojo.entity"); //此对象与数据库表结构一一对应，通过 DAO 层向上传输数据源对象。
        mpg.setPackageInfo(pc);
        // 5、策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);//数据库表字段映射到实体的命名策略
        strategy.setEntityLombokModel(true); // lombok
        strategy.setLogicDeleteFieldName("is_deleted");//逻辑删除字段名
        strategy.setEntityBooleanColumnRemoveIsPrefix(true);//去掉布尔值的is_前缀（确保tinyint(1)）
        strategy.setRestControllerStyle(true); //restful api风格控制器
        mpg.setStrategy(strategy);
        // 6、执行
        mpg.execute();
    }
}

// 5、策略配置

StrategyConfig strategy = new StrategyConfig(); strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略

strategy.setColumnNaming(NamingStrategy.underline_to_camel);//数据库表字段映射到实体的命名策略

strategy.setEntityLombokModel(true); // lombok

strategy.setLogicDeleteFieldName("is_deleted");//逻辑删除字段名

strategy.setEntityBooleanColumnRemoveIsPrefix(true);//去掉布尔值的is_前缀（确保tinyint(1)）

strategy.setRestControllerStyle(true); //restful api风格控制器

mpg.setStrategy(strategy);

六、启动应用程序

1、创建application.yml

server:
port: 8110 # 服务端口
spring:
profiles:
active: dev # 环境设置
application:
name: service-core # 服务名
datasource: # mysql数据库连接
type: com.zaxxer.hikari.HikariDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/srb_core?serverTimezone=GMT%2B8&characterEncoding=utf-8
username: root
password: 123456
mybatis-plus: #mybatis
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
mapper-locations: classpath:com/atguigu/srb/core/mapper/xml/*.xml

2、创建SpringBoot配置文件

在service-core中创建config包，创建MybatisPlusConfig类

@Configuration
@MapperScan("com.atguigu.srb.core.mapper")
@EnableTransactionManagement //事务处理
public class MybatisPlusConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));//分页
        return interceptor;
    }
}

3、创建SpringBoot启动类

注意：扫描com.atguigu.srb

@SpringBootApplication
@ComponentScan({"com.atguigu.srb"})
public class ServiceCoreApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceCoreApplication.class, args);
    }
}
