MyBatis-Plus动态分页查询

 1.前端请求，传当前页，每页大小，动态条件对象；

userSelect() {
          this.postRequest("/admin/doctorcondition?currentPage="+ this.currentPage + "&pagesize=" + this.pagesize, this.doctor).then(res => {
          this.doctorlist = []
          if (res.errorCode == -1) {
            var data = res.body.result.records
            for (let i = 0; i < data.length; i++) {
              this.doctorlist.push(data[i])
            }
            this.total = res.body.result.total;
          }
          console.log(res.body.result)
        });
      },

 请求URL

Request URL: http://localhost:8080/admin/doctorcondition?currentPage=1&pagesize=10

请求写的数据 

 

 2.接口根据动态条件构建QuerWrapper，使用selectPage进行分页查询；

Page<Doctor> objectpage=new Page<>(currentPage,pagesize);
            QueryWrapper<Doctor> qw=new QueryWrapper<>();
            if(!"".equals(doctor.getRole())&&doctor.getRole()!=null){
                qw.eq("role",doctor.getRole());
            }
            if(!"".equals(doctor.getTrueName())&&doctor.getTrueName()!=null){
                qw.like("true_name",doctor.getTrueName());
            }
            if(!"".equals(doctor.getHospital())&&doctor.getHospital()!=null){
                qw.like("hospital",doctor.getHospital());
            }
            if(!"".equals(doctor.getCellphone())&&doctor.getCellphone()!=null){
                qw.like("cellphone",doctor.getCellphone());
            }
            if(!"".equals(doctor.getEmail())&&doctor.getEmail()!=null){
                qw.like("email",doctor.getEmail());
            }
            Page<Doctor> doctors = doctorMapper.selectPage(objectpage, qw);

 根据条件查询了总页码count(1)，更具页码和每页大小，查询返回对象。
