一、上传科室接口

1. 添加科室基础类

A、添加 model

说明：由于实体对象没有逻辑，我们已经统一导入
com.fancy.yygh.model.hosp.Department

B、添加 repository

添加 com.fancy.yygh.hosp.repository.DepartmentRepository

package com.fancy.yygh.hosp.repository;


@Repository
public interface DepartmentRepository extends MongoRepository<Department,String> {

}

C、添加 service 接口及实现类

添加 com.fancy.yygh.hosp.service.DepartmentService 接口

package com.fancy.yygh.hosp.service;


public interface DepartmentService {

}

添加com.fancy.yygh.hosp.service.impl.DepartmentServiceImpl 接口实现

package com.fancy.yygh.hosp.service.impl;

@Service
@Slf4j
public class DepartmentServiceImpl implements DepartmentService {
	@Autowired
	private DepartmentRepository departmentRepository;
}

2. 上传科室

A、上传科室

医院编号是平台分配的，全局唯一，科室编号为医院自己的编号，相对医院唯一，上传科室接口可以多次调用，如果医院编号与科室编号组合唯一为更新操作

B、接口数据分析

{
	"hoscode": "1000_0",
	"depcode": "200050923",
	"depname": "门诊部核酸检测门诊(东院)",
	"intro": "门诊部核酸检测门诊(东院)",
	"bigcode": "44f162029abb45f9ff0a5f743da0650d",
	"bigname": "体检科"
}

说明：一个大科室下可以有多个小科室，如图：

C、添加 service 接口

在 DepartmentService 类添加接口

/**
 * 上传科室信息
 * @param paramMap
*/
void save(Map<String, Object> paramMap);

说明：参数使用 Map，减少对象封装，有利于签名校验，后续会体验到

在 DepartmentServiceImpl 类添加实现

@Override
public void save(Map<String, Object> paramMap) {
	Department department = JSONObject.parseObject(JSONObject.toJSONString(paramMap), Department.class);
	Department targetDepartment = departmentRepository.getDepartmentByHoscodeAndDepcode(department.getHoscode(), department.getDepcode());
	if(null != targetDepartment) {
		//copy不为null的值，该方法为自定义方法
		BeanUtils.copyBean(department, targetDepartment, Department.class);
		departmentRepository.save(targetDepartment);
	} else {
		department.setCreateTime(new Date());
		department.setUpdateTime(new Date());
		department.setIsDeleted(0);
		departmentRepository.save(department);
	}
}

D、添加 repository 接口

在DepartmentRepository添加方法

Department getDepartmentByHoscodeAndDepcode(String hoscode, String depcode);

E、添加 controller 接口

在 ApiController 类添加接口

@Autowired
private DepartmentService departmentService;

@ApiOperation(value = "上传科室")
@PostMapping("saveDepartment")
public Result saveDepartment(HttpServletRequest request) {
	Map<String, Object> paramMap = HttpRequestHelper.switchMap(request.getParameterMap());
	//必须参数校验 略
	String hoscode = (String)paramMap.get("hoscode");
	if(StringUtils.isEmpty(hoscode)) {
		throw new YyghException(ResultCodeEnum.PARAM_ERROR);
	}
	//签名校验
	if(!HttpRequestHelper.isSignEquals(paramMap, hospitalSetService.getSignKey(hoscode))) {
		throw new YyghException(ResultCodeEnum.SIGN_ERROR);
	}
	
	departmentService.save(paramMap);
	return Result.ok();
}

二、查询科室接口

一个医院有多个科室，因此我们采取分页查询方式

A、添加 service 接口

在 DepartmentService 类添加接口

/**
 * 分页查询
 * @param page 当前页码
 * @param limit 每页记录数
 * @param departmentQueryVo 查询条件
 * @return
*/
Page<Department> selectPage(Integer page, Integer limit, DepartmentQueryVo departmentQueryVo);

在 DepartmentServiceImpl 类添加实现

@Override
public Page<Department> selectPage(Integer page, Integer limit, DepartmentQueryVo departmentQueryVo) {
	Sort sort = Sort.by(Sort.Direction.DESC, "createTime");
	//0为第一页
	Pageable pageable = PageRequest.of(page-1, limit, sort);

	Department department = new Department();
	BeanUtils.copyProperties(departmentQueryVo, department);
	department.setIsDeleted(0);

	//创建匹配器，即如何使用查询条件
	ExampleMatcher matcher = ExampleMatcher.matching() //构建对象
		.withStringMatcher(ExampleMatcher.StringMatcher.CONTAINING) //改变默认字符串匹配方式：模糊查询
		.withIgnoreCase(true); //改变默认大小写忽略方式：忽略大小写

	//创建实例
	Example<Department> example = Example.of(department, matcher);
	Page<Department> pages = departmentRepository.findAll(example, pageable);
	return pages;
}

B、添加 controller 接口

在 ApiController 类添加接口

@ApiOperation(value = "获取分页列表")
@PostMapping("department/list")
public Result department(HttpServletRequest request) {
    Map<String, Object> paramMap = HttpRequestHelper.switchMap(request.getParameterMap());
	
	//必须参数校验 略
	String hoscode = (String)paramMap.get("hoscode");
	
	//非必填
	String depcode = (String)paramMap.get("depcode");
	int page = StringUtils.isEmpty(paramMap.get("page")) ? 1 : Integer.parseInt((String)paramMap.get("page"));
	int limit = StringUtils.isEmpty(paramMap.get("limit")) ? 10 : Integer.parseInt((String)paramMap.get("limit"));

	if(StringUtils.isEmpty(hoscode)) {
		throw new YyghException(ResultCodeEnum.PARAM_ERROR);
    }
	//签名校验
	if(!HttpRequestHelper.isSignEquals(paramMap, hospitalSetService.getSignKey(hoscode))) {
		throw new YyghException(ResultCodeEnum.SIGN_ERROR);
    }

	DepartmentQueryVo departmentQueryVo = new DepartmentQueryVo();
	departmentQueryVo.setHoscode(hoscode);
	departmentQueryVo.setDepcode(depcode);
	Page<Department> pageModel = departmentService.selectPage(page, limit, departmentQueryVo);
	return Result.ok(pageModel);
}

三、删除科室接口

根据医院编号与科室编号删除科室

A、添加 service 接口

在 DepartmentService 类添加接口

/**
 * 删除科室
 * @param hoscode
* @param depcode
*/
void remove(String hoscode, String depcode);

在 DepartmentServiceImpl 类添加实现

@Override
public void remove(String hoscode, String depcode) {
	Department department = departmentRepository.getDepartmentByHoscodeAndDepcode(hoscode, depcode);
	if(null != department) {
		//departmentRepository.delete(department);
		departmentRepository.deleteById(department.getId());
	}
}

B、添加 controller 接口

在 ApiController 类添加接口

@ApiOperation(value = "删除科室")
@PostMapping("department/remove")
public Result removeDepartment(HttpServletRequest request) {
	Map<String, Object> paramMap = HttpRequestHelper.switchMap(request.getParameterMap());
	//必须参数校验 略
	String hoscode = (String)paramMap.get("hoscode");
	//必填
	String depcode = (String)paramMap.get("depcode");
	if(StringUtils.isEmpty(hoscode)) {
		throw new YyghException(ResultCodeEnum.PARAM_ERROR);
	}
	//签名校验
	if(!HttpRequestHelper.isSignEquals(paramMap, hospitalSetService.getSignKey(hoscode))) {
		throw new YyghException(ResultCodeEnum.SIGN_ERROR);
	}
	
	departmentService.remove(hoscode, depcode);
	return Result.ok();
}
