<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>

<artifactId>springfox-swagger2</artifactId>
</dependency>
<!--swagger ui-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
</dependency>
</dependencies>四、创建模块service-core
1、创建Maven模块
在srb下创建普通maven模块
Group：com.atguigu
Artifact：service-core
2、配置pom
注意：依赖service-base
<dependencies>
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>service-base</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</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 + "/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);
}
