小程序开发之结合Springboot查询数据

 小程序端JS

 onQuery: function() {
        var a=1;
        wx.request({
            url: 'http://localhost:8081/excelData/getwe?id='+a,//模拟查询id为1的数据
            header: {
              'content-type': 'application/json' // 默认值
            },
            success: res => {
              console.log(res.data)
 
            },
          })
      },

 

JAVA后台Control

@RestController
@RequestMapping("/weDemo")
public class WeDemoControl {
    @Autowired
    private StudentService studentService;

    @RequestMapping(value = "/getwe")
    public List<Student>  getstus(String id){
        List<Student> students= studentService.getStus(id);
        return students;
    }


}
