6.common base-service
引入依赖:
<dependencies><dependency><groupId>com.lee</groupId><artifactId>util-service</artifactId><version>0.0.1-SNAPSHOT</version></dependency></dependencies>
7.配置类config 1.MyBatisConfig 2.SwaggerConfig
MyBatisConfig
@Configuration
public class MyBatisConfig {@Beanpublic ISqlInjector getISqlInjector(){return new LogicSqlInjector();}//分页插件@Beanpublic PaginationInterceptor getPaginationInterceptor(){return new PaginationInterceptor();}
}SwaggerConfig
@Configuration
@EnableSwagger2
public class SwaggerConfig {@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("教育系统API文档").description("本文档描述了教育系统微服务接口定义").version("1.0").contact(new Contact("AAA", "http://www.aaa.com", "2300316070@qq.com")).build();}
}8.配置异常类exception 1.AAAException 2.GlobalException
AAAException
@Data
@NoArgsConstructor
@AllArgsConstructor
@Component
public class AAAException extends RuntimeException{private Integer code;private String msg;
}
GlobalException
@RestControllerAdvice
public class GlobalException {@ExceptionHandlerpublic R handlerException(Exception e){return R.error().data("msg",e.getMessage());}
}9.util-service返回结果实体类
R

@NoArgsConstructor
@ApiModel("返回结果实体类")
public class R {//是否成功private Boolean success;//返回的消息private String message;//返回的状态码 2000 2001private Integer code;//返回的数据private Map<String,Object> data = new HashMap<>();//成功的方法 static修饰的方法,可以通过类名直接调用该方法public static R ok(){R r = new R();r.setCode(2000);r.setSuccess(true);r.setMessage("成功");return r;}//失败的方法public static R error(){R r = new R();r.setSuccess(false);r.setCode(2001);r.setMessage("失败");return r;}//放置数据 key,value形式public R data(String key,Object value){this.data.put(key, value);return this;}//this表示调用者对象 map 集合public R data(Map<String,Object> map){this.setData(map);return this;}

#指定xml文件的路径

#日志
logging:level:com.lee.eduservice.mapper: debug12.配置主启动类
EduServiceMainApp
@SpringBootApplication
@MapperScan(basePackages = {"com.lee.eduservice.mapper"})
@EnableSwagger2
public class EduServiceMainApp {public static void main(String[] args) {SpringApplication.run(EduServiceMainApp.class,args);}
}
13.因为版本问题不最新版本,这里如果要使用注解@TableLogic需要进行一下操作 注解@TableLogic 逻辑删除,伪删除
@TableLogic
@TableLogicprivate Boolean isDeleted;
需要配置的config文件,标明当前是伪删除的配置类
@Configuration
public class MyBatisConfig {@Beanpublic ISqlInjector getISqlInjector(){return new LogicSqlInjector();}}
14.分页插件 PaginationInterceptor
@Configuration
public class MyBatisConfig {//分页插件@Beanpublic PaginationInterceptor getPaginationInterceptor(){return new PaginationInterceptor();}
}
15.vo.TeacherQuery
16.controller层实现检索查询
17.OSS
1.创建一个bucket
