SSM仓库管理系统货架怎么加

在SSM（Spring + Spring MVC + MyBatis）框架下实现仓库管理系统的货架管理功能，需要对系统进行模块化设计。以下是详细的步骤和示例代码：

1. 首先，创建一个货架实体类（ShelfEntity）：

```java

public class ShelfEntity {

private Integer id;

private String name;

private Integer quantity;

private Double price;

// getter and setter methods

}

```

2. 创建一个货架管理接口（ShelfManagementService）：

```java

@Service

public interface ShelfManagementService {

List getAllShelves();

ShelfEntity addNewShelf(ShelfEntity shelf);

ShelfEntity updateShelf(ShelfEntity shelf);

void deleteShelf(Integer id);

}

```

3. 创建一个货架管理控制器（ShelfManagementController）：

```java

@RestController

@RequestMapping("/shelves")

public class ShelfManagementController {

@Autowired

private ShelfManagementService shelManagementService;

@GetMapping

public List getAllShelves() {

return shelManagementService.getAllShelves();

}

@PostMapping

public ShelfEntity addNewShelf(@RequestBody ShelfEntity shelf) {

return shelManagementService.addNewShelf(shelf);

}

@PutMapping("/{id}")

public ShelfEntity updateShelf(@PathVariable Integer id, @RequestBody ShelfEntity shelf) {

return shelManagementService.updateShelf(shelf);

}

@DeleteMapping("/{id}")

public void deleteShelf(@PathVariable Integer id) {

shelManagementService.deleteShelf(id);

}

}

```

4. 创建仓库管理服务层（ShelfManagementServiceImpl）：

```java

@Service

public class ShelfManagementServiceImpl implements ShelfManagementService {

@Autowired

private ShelfRepository shelfRepository;

@Override

public List getAllShelves() {

return shelfRepository.findAll();

}

@Override

public ShelfEntity addNewShelf(ShelfEntity shelf) {

return shelfRepository.save(shelf);

}

@Override

public ShelfEntity updateShelf(ShelfEntity shelf) {

return shelfRepository.save(shelf);

}

@Override

public void deleteShelf(Integer id) {

shelfRepository.deleteById(id);

}

}

```

5. 创建仓库管理数据访问层（ShelfRepository）：

```java

@Repository

public interface ShelfRepository extends JpaRepository {

}

```

6. 创建仓库管理持久层（ShelfPersistenceService）：

```java

@Service

public class ShelfPersistenceService {

@Autowired

private ShelfManagementService shelManagementService;

public List getAllShelves() {

return shelManagementService.getAllShelves();

}

public ShelfEntity addNewShelf(ShelfEntity shelf) {

return shelManagementService.addNewShelf(shelf);

}

public ShelfEntity updateShelf(ShelfEntity shelf) {

return shelManagementService.updateShelf(shelf);

}

public void deleteShelf(Integer id) {

shelManagementService.deleteShelf(id);

}

}

```

7. 创建仓库管理测试类（ShelfManagementTest）：

```java

@RunWith(SpringRunner.class)

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

public class ShelfManagementTest {

@Autowired

private ShelfPersistenceService shelPersistenceService;

@Test

public void testAddNewShelf() {

ShelfEntity newShelf = new ShelfEntity();

newShelf.setName("新货架");

newShelf.setQuantity(10);

newShelf.setPrice(100.0);

System.out.println("新货架数量：" + newShelf.getQuantity());

ShelfEntity result = shelPersistenceService.addNewShelf(newShelf);

System.out.println("新货架数量：" + result.getQuantity());

}

}

```

以上是一个简单的SSM仓库管理系统货架添加功能的实现示例。在实际开发中，还需要考虑数据库连接、事务处理、异常处理等问题。
