Spring Boot 2.x 编写 RESTful API (四) 使用 Mybatis

用Spring Boot编写RESTful API 学习笔记

添加依赖

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.41</version>
        </dependency>

添加配置

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/tvseries?useSSL=false
    username: root
    password: root
    
    
mybatis:
  configuration:
    map-underscore-to-camel-case: true # 下划线转驼峰命名

启动类添加

@MapperScan("com.karonda.restapi.dao")

新建 dao

public interface TvSeriesDao {

    @Select("select * from tv_series")
    public List<TvSeries> getAll();
}

新建 service

@Service
public class TvSeriesService {
    @Autowired
    TvSeriesDao tvSeriesDao;

    public List<TvSeries> getAllSeries(){
        return tvSeriesDao.getAll();
    }
}

修改 Controller

    @Autowired
    TvSeriesService tvSeriesService;
    
    @GetMapping
    public List<TvSeries> getAll() {
        if(log.isTraceEnabled()) {
            log.trace("getAll() ");
        }
        List<TvSeries> list = tvSeriesService.getAllSeries();
        
        return list;
    }
