Springboot + Mybatis-Plus代码生成指南

使用 Spring Boot 和 MyBatis-Plus 生成代码，可以大大简化开发流程，可以保持编码的规范性，生成单元测试等。以下是详细步骤：

配置pom.xml

<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.4.1</version>
</dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-generator</artifactId><version>3.4.1</version>
</dependency><!-- velocity-->
<dependency><groupId>org.apache.velocity</groupId><artifactId>velocity-engine-core</artifactId><version>2.0</version>
</dependency><!-- swagger-->
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.8.0</version>
</dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.8.0</version>
</dependency><!-- 单元测试相关-->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope>
</dependency>

配置数据库连接

在 src/main/resources/application.properties 或 application.yml 中配置数据库连接信息：

server:port: 8000
spring:application:name: ocean-code-generationjackson:date-format: yyyy-MM-dd HH:mm:sstime-zone: GMT+8deserialization.accept_empty_string_as_null_object: truedatasource:driverClassName: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/db-ocean?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&allowMultiQueries=trueusername: rootpassword: 123456mvc:pathmatch:matching-strategy: ANT_PATH_MATCHERmybatis-plus:mapper-locations: classpath*:mapper/*Mapper.xmlconfiguration:log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
