创建MyBatis-Plus版的后端查询项目

记得编码和maven库的检测！！！

1、maven库导入包

		<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>3.0.5</version></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-spring-boot3-starter</artifactId><version>3.5.12</version></dependency><!-- https://mvnrepository.com/artifact/com.baomidou/mybatis-plus-jsqlparser --><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-jsqlparser</artifactId><version>3.5.12</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope><optional>true</optional></dependency><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>

2、配置文件

spring:application:name: crm2026datasource:driver-class-name: com.mysql.cj.jdbc.Driverusername: rootpassword: 123456url: jdbc:mysql://localhost:3306/demo02?characterEncoding=UTF-8&useSSL=false&autoReconnect=true&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=truemybatis-plus:configuration:log-prefix: mybatis.log-impl: org.apache.ibatis.logging.commons.JakartaCommonsLoggingImplmap-underscore-to-camel-case: truelazy-loading-enabled: truetype-aliases-package: com.situ.crm2026.modelmapper-locations: classpath*:/mapper/**/*.xmlserver:port: 8080logging:level:mybatis: debug

3、必要类

1、实体类

2、创建时间那、创建者啊，这些不变的数据单独封装

3、较为简单的 响应 封装类

4、后端传来时间范围时，用这个接受处理，而且继承了基础实体类

4、逻辑方面

1、dao层


要想成功分页，还需对分页功能进行配置

2、Service接口

3、api接口层
