今日必会
1.简单的搭建环境。要明白什么时候是pom/war/jar
yygh_parent <pom>
common <pom>
model 无
service <pom>
2.各个模块的作用
common：工具类，所有的模块都要依赖他。
common_utils:用于返回结果的封装。
service_utils:用于swagger的配置，还配置了统一处理异常，所以引入了common_utils
model :实体类
service：api接口服务
service_hosp:医院api接口
1. config：配置类，他是mapper的配置类说白了就是dao层配置（数据库和后台）里面有分页插件。
2.controller:这是前台地址第一次到达的地方，处理HTTP请求，并将请求的数据传递给其他层进行处理。里面有CRUD。
3.mapper：Mapper层负责处理数据的持久化和访问。
4. service：本层起到了连接Controller层和Mapper层的桥梁作用，负责实现业务逻和数据操作的协调，是实现系统功能的关键部分。
3.了解每个接口的参数和返回值
※新增：参数：hospitalset 返回值：R.ok()
※修改：要先进行数据回显，
根据id查询信息， 参数：id 返回值：R（HospitalSet）
然后修改医院设置（保存接口） 参数: HospitalSet 返回值：R.ok（）
※批量删除 参数：list<long>idlis 返回值：R.ok()
※锁定医院 参数：id ，status 返回值：R.ok()
4.了解分页的逻辑
5.了解get/post/delete mapping
以下代码必须全会敲
//医院设置接口
@RestController
@RequestMapping("/admin/hosp/hospitalSet")
public class HospitalSetController {
@Autowired
private HospitalSetService hospitalSetService;
//chaxun
//查询所有医院设置
//查询所有医院设置
@ApiOperation(value = "医院设置列表")
@GetMapping("findAll")
public R findAll() {
List<HospitalSet> list = hospitalSetService.list();
return R.ok().data("list",list);
}
@ApiOperation(value = "医院设置删除")
@DeleteMapping("{id}")
public R removeById(@ApiParam(name = "id", value = "讲师ID", required = true) @PathVariable String id){
hospitalSetService.removeById(id);
return R.ok();
}
@ApiOperation(value="分页查询")
@GetMapping("pageQuery/{page}/{limit}")
public R pageQuery(@PathVariable Long page,@PathVariable Long limit){
//1.封装分页参数
Page<HospitalSet> pageparm = new Page<>(page,limit);
//2.实现分页查询
hospitalSetService.page(pageparm);
//3.取出结果
List<HospitalSet> recods = pageparm.getRecords();
Long total = pageparm.getTotal();
//4.封装返回
return R.ok().data("recods",recods).data("total",total);
}
@ApiOperation(value="分页查询加条件")
@GetMapping("pageQuer/{page}/{limit}")
public R pagelist(@PathVariable Long page, @PathVariable Long limit, @RequestBody HospitalSetQueryVo hospitalSetQueryVo){
//1.
String hosname = hospitalSetQueryVo.getHosname();
String hoscode = hospitalSetQueryVo.getHoscode();
QueryWrapper<HospitalSet> wrapper = new QueryWrapper<>();
if(!StringUtils.isEmpty(hosname)){
wrapper.like("hosname",hosname);
}
if (!StringUtils.isEmpty(hoscode)){
wrapper.eq("hoscode",hoscode);
}
//1.封装分页参数
Page<HospitalSet> pageparm = new Page<>(page,limit);
//2.实现分页查询
hospitalSetService.page(pageparm,wrapper);
//3.取出结果
List<HospitalSet> recods = pageparm.getRecords();
Long total = pageparm.getTotal();
//4.封装返回
return R.ok().data("records",recods).data("total",total);
}
@ApiOperation(value = "新增医院设置")
@PostMapping("save")
public R save(@RequestBody HospitalSet hospitalSet){
boolean save = hospitalSetService.save(hospitalSet);
if(save){
return R.ok();
}else {
return R.error();
}
}
// 新增加 新加
@ApiOperation(value = "根据id查询信息")
@GetMapping("getById/{id}")
public R getById(@PathVariable Long id){
HospitalSet hospitalSet = hospitalSetService.getById(id);
return R.ok().data("hospitalSet",hospitalSet);
}
//修改医院设置
@ApiOperation(value = "修改医院设置")
@PostMapping("update")
public R update(@RequestBody HospitalSet hospitalSet)
{
boolean update = hospitalSetService.updateById(hospitalSet);
if(update){
return R.ok();
}else {
return R.error();
}
}
// 1.
@ApiOperation(value = "根据id集合批量删除")
@DeleteMapping("delByIds")
public R delByIds(@RequestBody List<Long> idList){
boolean remove = hospitalSetService.removeByIds(idList);
if(remove){
return R.ok();
}else {
return R.error();
}
}
//2.
@ApiOperation(value = "医院设置锁定和解锁")
@PutMapping("lockHospitalSet/{id}/{status}")
public R lockHospitalSet(@PathVariable Long id,
@PathVariable Integer status) {
//1根据id查询数据
HospitalSet hospitalSet = hospitalSetService.getById(id);
//2修改数据
hospitalSet.setStatus(status);
hospitalSetService.updateById(hospitalSet);
return R.ok();
}

<!-- 服务注册
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>-->
</dependencies> （3）删除src
7、搭建医院模块service_hosp模块 （1）在父模块·service模块下面创建子模块service_hosp
|
医院设置模块搭建
医院设置主要是用来保存开通医院的一些基本信息，每个医院一条信息，保存了医院编号（平台分配，全局唯一）和接口调用相关的签名key等信息，是整个流程的第一步，只有开通了医院设置信息，才可以上传医院相关信息。我们所开发的功能就是基于单表的一个CRUD、锁定/解锁和发送签名信息这些基本功能。 2、改造service_hosp模块 （1）resources目录下创建文件 application.properties # 服务端口
server.port=8201
# 服务名
spring.application.name=service-hosp
# 环境设置：dev、test、prod
spring.profiles.active=dev
# mysql数据库连接
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/yygh_hosp?characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=123123
#返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
#mybatis日志
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl （2）创建主目录、启动类
@SpringBootApplication
public class ServiceHospApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceHospApplication.class,args);
}
} 3、搭建MP框架 （1）确认实体
（2）搭建mapper
public interface HospitalSetMapper extends BaseMapper<HospitalSet> {
} （3）搭建service
public interface HospitalSetService extends IService<HospitalSet> {
} @Service
public class HospitalSetServiceImpl
extends ServiceImpl<HospitalSetMapper, HospitalSet>
implements HospitalSetService {
}
（4）搭建controller //医院设置接口
@RestController
@RequestMapping("/admin/hosp/hospitalSet")
public class HospitalSetController {
@Autowired
private HospitalSetService hospitalSetService;
@GetMapping("findAll")
public List<HospitalSet> findAll(){
List<HospitalSet> list = hospitalSetService.list();
return list;
}
}
（5）创建配置类 @Configuration
@EnableTransactionManagement
@MapperScan("com.atguigu.yygh.hosp.mapper")
public class HospConfig {
}
（6）启动测试
（7）实现删除
@DeleteMapping("{id}")
public boolean delHospset(@PathVariable Long id){
boolean remove = hospitalSetService.removeById(id);
return remove;
}
配置使用Swagger2
统一返回结果
实现带条件带分页查询接口
新增、修改接口开发
批量删除、锁定医院设置
统一异常处理
