谷粒学院项目笔记第一部分

1.环境搭建，准备工作

（1）创建数据库

（2）创建项目完整结构

（3）父工程springboot,子工程maven

（4）父工程pom设置版本，添加pom

#版本
<version>2.2.1.RELEASE</version>
#包
<packaging>pom</packaging>

（4）删除父工程dependencies依赖，只放管理依赖的版本

 添加版本依赖

#添加 <properties>确定依赖的版本
<properties><java.version>1.8</java.version><guli.version>0.0.1-SNAPSHOT</guli.version><mybatis-plus.version>3.0.5</mybatis-plus.version>

在父工程下创建service,创建后添加

<packaging>pom</packaging>

将相关依赖引入

 在service2下创建service-edu2

创建application.properties配置文件

# 服务器端口号
service.port=8001
# 服务名
spring.application.name=service-edu
# 环境设置dev,test,prod
spring.profiles.active=dev
# 数据库连接
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/guli?serverTimezone=GMT%2B8&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=123456# mybaties日志
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

代码生成器，生成相关的层级结构

代码生成器的依赖

<!-- velocity 模板引擎, Mybatis Plus 代码生成器需要 --><dependency><groupId>org.apache.velocity</groupId><artifactId>velocity-engine-core</artifactId></dependency>

test里面使用代码生成器，构建数据库对应表的层级结构

package com.atguigu.test;import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import org.junit.Test;/* @author* @since 2018/12/13*/
public class CodeGenerator2 {@Testpublic void run() {// 1、创建代码生成器AutoGenerator mpg = new AutoGenerator();// 2、全局配置GlobalConfig gc = new GlobalConfig();//得到当前项目文件夹的路径String projectPath = System.getProperty("user.dir");//这里的 projectPath 路径最好改为绝对路径gc.setOutputDir("D:\\\\Codeware\\\\ideaCode\\\\guli\\\\guli_parent\\\\service\\\\service_edu" + "/src/main/java");gc.setAuthor("testjava");//生成后是否打开代码的文件夹gc.setOpen(false);//重新生成时文件是否覆盖，比如写了代码后，再次生成gc.setFileOverride(false);//去掉Service接口的首字母I，命名规则gc.setServiceName("%sService");//主键策略，对应实体类中设置的类型，long-ID_WORKER,字符串-ID_WORKER_STRgc.setIdType(IdType.ID_WORKER_STR);//定义生成的实体类中日期类型，datetime-dategc.setDateType(DateType.ONLY_DATE);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/guli?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");//生成的包名pc.setModuleName("eduservice"); //包名.模块名.pc.setController("controller");pc.setEntity("entity");pc.setService("service");pc.setMapper("mapper");mpg.setPackageInfo(pc);// 5、策略配置,根据表生成出代码StrategyConfig strategy = new StrategyConfig();// 多张表，""strategy.setInclude("edu_course","edu_course_description","edu_chapter","edu_video");strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略strategy.setTablePrefix(pc.getModuleName() + "_"); //生成实体时去掉_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 模型 @Accessors(chain = true) setter链式操作strategy.setRestControllerStyle(true); //restful api风格控制器strategy.setControllerMappingHyphenStyle(true); //url中驼峰转连字符mpg.setStrategy(strategy);// 6、执行mpg.execute();}
}

整合swagger

1.创建一个公共的类common来管理，引入依赖

<packaging>pom</packaging><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><scope>provided </scope></dependency><!--mybatis-plus--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><scope>provided </scope></dependency><!--lombok用来简化实体类：需要安装lombok插件--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><scope>provided </scope></dependency><!--swagger--><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><scope>provided </scope></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><scope>provided </scope></dependency><!-- redis --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><!-- spring2.X集成redis所需common-pool2<dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId><version>2.6.0</version></dependency>--></dependencies>

然后在common下,创建service_base，创建swagger的配置类,进行bean配置

@Configuration
@EnableSwagger2
public class SwaggerConfig2 {@Beanpublic Docket webApiConfig(){return new Docket(DocumentationType.SWAGGER_2).groupName("webApi").apiInfo(webApiInfo()).select().paths(Predicates.not(PathSelectors.regex("/admin/.*"))).paths(Predicates.not(PathSelectors.regex("/error.*"))).build();}private ApiInfo webApiInfo(){return new ApiInfoBuilder().title("网站-课程中心API文档").description("本文档描述了课程中心微服务接口定义").version("1.0").contact(new Contact("Helen", "http://atguigu.com","55317332@qq.com")).build();}
}

在要使用该功能的模块下引入

 <!--引入swagger--><dependency><groupId>com.atguigu</groupId><artifactId>service_base2</artifactId><version>0.0.1-SNAPSHOT</version></dependency>

在service_edu的启动类上加

@ComponentScan(basePackages = {"com.atguigu"})

三个注意：swagger配置类，mapper扫描，@ComponentScan(basePackages = {"cn.lf"})扫描

配置config类扫描mapper

并将其注册为 MyBatis 的 Mapper。这样，在使用 Mapper 接口时，就不需要手动编写对应的实现类了。
