SpringBoot（二）

空气质量检测的一个小案例：

（1）创建数据库

（2）引入各种需要的依赖或者xml文件

yml文件：

server:
  port: 8080
spring:
    jackson:
        date-format: yyyy-MM-dd HH:mm:ss
        time-zone: GMT+8
    thymeleaf:
        prefix: classpath:/templates/
        mode: HTML5
        cache: false
    datasource:
        name: test
        url: jdbc:mysql://localhost:3306/air
        username: root
        password:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.jdbc.Driver
        filters: stat
        maxActive: 20
        initialSize: 1
        maxWait: 60000
        minIdle: 1
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: select 'x'
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        maxOpenPreparedStatements: 20

mybatis:
  mapper-locations: classpath:mapping/*.xml
  type-aliases-package: com.wp.entity
（3）创建包

@Controller
public class AirController {
    @Resource(name="airService")
    private IAirService iAirService;

    @RequestMapping("/main")
    public String main(){
         return "main";
    }


    //查询所有
    @RequestMapping("/allair")
    @ResponseBody
    public Object allair(Model model) throws Exception {
        List<Air> list = iAirService.allair();
        return list;
    }


    //根据区域查询所在区域的所有检测记录
    @RequestMapping("/disair")
    @ResponseBody
    public Object airbydis(Model model,String district) throws Exception {
        List<Air> list = iAirService.airbydis(district);
        return list;
    }


    //添加的页面
    @RequestMapping("/add")
    public String add(){
        return "addAir";
    }

    //添加检测数据
    public String addair(Air air) throws Exception {
        int addair = iAirService.addair(air);
        if (addair>0){
            return "main";
        }else {
            return "addAir";
        }
    }
