好的,根据您的需求,我可以提供以下代码供您参考:
1. 创建商品类(Goods.java):
```java
public class Goods {
private Long id;
private String name;
private Double price;
// 其他属性和get/set方法省略
}
```
2. 创建商品服务接口(GoodsService.java):
```java
public interface GoodsService {
List<Goods> getGoodsList();
}
```
3. 实现商品服务接口(GoodsServiceImpl.java):
```java
@Service
public class GoodsServiceImpl implements GoodsService {
@Autowired
private GoodsMapper goodsMapper;
@Override
public List<Goods> getGoodsList() {
return goodsMapper.selectList(null);
}
}
```
4. 创建商品控制器(GoodsController.java):
```java
@RestController
@RequestMapping("/goods")
public class GoodsController {
@Autowired
private GoodsService goodsService;
@GetMapping("/list")
public List<Goods> getGoodsList() {
return goodsService.getGoodsList();
}
}
```
5. 配置数据库连接(application.properties):
```properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/db_name?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8
spring.datasource.username=username
spring.datasource.password=password
```
6. 创建商品Mapper接口(GoodsMapper.java):
```java
@Mapper
public interface GoodsMapper extends BaseMapper<Goods> {
}
```
7. 配置MyBatis-Plus(MybatisPlusConfig.java):
```java
@Configuration
@MapperScan("com.example.demo.mapper")
public class MybatisPlusConfig {
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}
}
```
以上代码实现了一个简单的商品列表接口,返回JSON格式数据。需要根据您的具体业务场景进行修改和完善。
