springboot-3.2.1 集成 mybatis、分页插件pagehelper和接口文档swagger

为了在Spring Boot 3.2.1中集成MyBatis、PageHelper和Swagger，你需要按照以下步骤操作：

1. 在pom.xml中添加依赖：

<!-- MyBatis -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>3.0.1</version>
</dependency>
 
<!-- PageHelper -->
<dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper-spring-boot-starter</artifactId>
    <version>1.4.1</version>
</dependency>
 
<!-- Swagger -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

2. 配置application.properties或application.yml文件，添加数据库连接信息和PageHelper的配置：

# 数据库连接信息
spring.datasource.url=jdbc:mysql://localhost:3306/your_database?useSSL=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
 
# PageHelper 配置
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql

3. 创建Mapper接口和对应的XML文件，并使用PageHelper进行分页：

// Mapper接口
public interface YourMapper {
    List<YourEntity> selectAll(@Param("param") Map<String, Object> param);
}
 
// XML映射文件
<mapper namespace="YourMapper">
    <select id="selectAll" resultType="YourEntity">
        SELECT * FROM your_table
        WHERE some_condition = #{param.someCondition}
    </select>
</mapper>
 
// Service中使用PageHelper进行分页
public PageInfo<YourEntity> getPage(int pageNum, int pageSize, Map<String, Object> param) {
    PageHelper.startPage(pageNum, pageSize);
    List<YourEntity> list = yourMapper.selectAll(param);
    return new PageInfo<>(list);
}

4. 配置Swagger。创建一个配置类来指定Swagger的相关配置：

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }
}

5. 在Controller中使用Swagger注解来描述API：

@RestController
@Api(tags = "Your Controlle
