config配置
mybatis-plus
具体配置mybaits-plus配置
注解
// 配置文件
Configuration
// 开启事务管理
EnableTransactionManagement
// mapper扫描
MapperScan(com.yu.mapper)插件bean 这里先只配置分页插件
Beanpublic MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor new MybatisPlusInterceptor();//分页插件interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));return interceptor;}自动填充bean Beanpublic GlobalConfig globalConfig() {GlobalConfig globalConfig new GlobalConfig();globalConfig.setMetaObjectHandler(new MyMetaObjectHandler());return globalConfig;}这里有2种写法注释掉的是低版本的。高版本从3.3.0开始可以使用。不过3.3.0不要使用。有bug。
Component
public class MyMetaObjectHandler implements MetaObjectHandler {/*** 新增填充创建时间** param metaObject*/Overridepublic void insertFill(MetaObject metaObject) {
// this.strictInsertFill(metaObject, createTime, LocalDateTime::now, LocalDateTime.class);
// this.strictUpdateFill(metaObject, updateTime, LocalDateTime::now, LocalDateTime.class);this.fillStrategy(metaObject,createTime,LocalDateTime.now());this.fillStrategy(metaObject,updateTime,LocalDateTime.now());}/*** 更新填充更新时间** param metaObject*/Overridepublic void updateFill(MetaObject metaObject) {
// this.strictUpdateFill(metaObject, updateTime, LocalDateTime::now, LocalDateTime.class);this.fillStrategy(metaObject,updateTime,LocalDateTime.now());}}
swagger
Configuration
public class SwaggerConfig {/*** 接口信息*/Beanpublic OpenAPI apiInfo() {return new OpenAPI().components(new Components().addSecuritySchemes(Authorization,new SecurityScheme().type(SecurityScheme.Type.HTTP).scheme(bearer).bearerFormat(JWT))).info(new Info().title(xiao-yu-Dormitory 接口文档).version(1.0.0).description(接口文档));}/*** 系统接口分组*/Beanpublic GroupedOpenApi systemApi() {String[] paths {/**};String[] packagesToScan {com.yu.controller};return GroupedOpenApi.builder().group(系统接口).packagesToScan(packagesToScan).pathsToMatch(paths).build();}}
生成实体、mapper和service
我直接用mybatisX进行生成 通过右键表可以 选择模块 基础包
baseEntity
在common包下新建一个类 用于规范创建和更新时间的类
Data
public class BaseEntity implements Serializable {Serialprivate static final long serialVersionUID 1L;TableField(fill FieldFill.INSERT)JsonInclude(value JsonInclude.Include.NON_NULL)JsonFormat(pattern yyyy-MM-dd HH:mm:ss)private LocalDateTime createTime;TableField(fill FieldFill.INSERT_UPDATE)JsonInclude(value JsonInclude.Include.NON_NULL)JsonFormat(pattern yyyy-MM-dd HH:mm:ss)private LocalDateTime updateTime;
}
统一响应实例
响应码接口
public interface IResultCode {String getCode();String getMsg();}
响应码接口实现
AllArgsConstructor
NoArgsConstructor
public enum ResultCode implements IResultCode, Serializable {SUCCESS(00000, ok),Overridepublic String getCode() {return code;}Overridepublic String getMsg() {return msg;}private String code;private String msg;Overridepublic String toString() {return { \code\:\ code \ , \msg\:\ msg \ };}public static ResultCode getValue(String code){for (ResultCode value : values()) {if (value.getCode().equals(code)) {return value;}}return SYSTEM_EXECUTION_ERROR; }
}统一响应result
EqualsAndHashCode(callSuper true)
public record ResultT(String code,T data,String msg
) implements Serializable{public static T ResultT success() {return success(null);}public static T ResultT success(T data) {return new Result(ResultCode.SUCCESS.getCode(),data,ResultCode.SUCCESS.getMsg());}public static T ResultT failed() {return result(ResultCode.SYSTEM_EXECUTION_ERROR.getCode(), ResultCode.SYSTEM_EXECUTION_ERROR.getMsg(), null);}public static T ResultT failed(String msg) {return result(ResultCode.SYSTEM_EXECUTION_ERROR.getCode(), msg, null);}public static T ResultT judge(boolean status) {if (status) {return success();} else {return failed();}}public static T ResultT failed(IResultCode resultCode) {return result(resultCode.getCode(), resultCode.getMsg(), null);}public static T ResultT failed(IResultCode resultCode, String msg) {return result(resultCode.getCode(), msg, null);}private static T ResultT result(IResultCode resultCode, T data) {return result(resultCode.getCode(), resultCode.getMsg(), data);}private static T ResultT result(String code, String msg, T data) {return new Result(code, data, msg);}public static boolean isSuccess(Result? result) {return result ! null ResultCode.SUCCESS.getCode().equals(result.code());}
}
统一分页响应
public record PageResultT(String code,DataT data,String msg
) implements Serializable {public static T PageResultT success(IPageT page) {DataT data new DataT(page.getRecords(), page.getTotal());return new PageResultT(ResultCode.SUCCESS.getCode(), data, ResultCode.SUCCESS.getMsg());}public record DataT(ListT list, long total) {}}
