CRM--首页数据--商机转化龙虎榜 （接口实现）

需求：

在一段时间范围内，统计哪些部门员工将商机转合同的最多，并计算转化率

对于商机总数来说这里的时间范围指的是商机的创建时间

对于每个用户转化了多少个商机来说，时间范围指的是合同的创建时间

合同的创建时间即商机转合同的时间

注意：最多展示10条

接口名/index/businessChangeStatistics

请求方式Get

参数列表

传入参数：

/index/businessChangeStatistics?beginCreateTime=2021-02-02&endCreateTime=2022-02-17

beginCreateTime 开始时间

endCreateTime 结束时间

返回值：

{
    "msg":"操作成功",
    "code":200,
    "data":[
        {
            "create_by":"zhangkai",			   		用户名称
            "deptName":"商机部",					  部门名称
            "num":100,								转化数量
            "radio":31.65							转化率
        },
        {
            "create_by":"admin",
            "deptName":"研发部门",
            "num":9,
            "radio":2.85
        },
        {
            "create_by":"shangji",
            "deptName":"新人创建演示用部门",
            "num":1,
            "radio":0.32
        },
        {
            "create_by":"shangji1",
            "deptName":"销售部门",
            "num":1,
            "radio":0.32
        }
    ]
}

步骤：

1.阅读产品文档（接口名，请求方式，参数列表）

2.根据产品的返回值和接收参数构建VO类

3.编写mapper层操作数据库

4.编写service层操作数据

5.编写controller层接收参数和返回数据

TbBusinessMapper.xml

 
       select count(id) from tb_business
        
            
                and date_format(create_time,'%y-%m-%d') >= date_format(#{beginCreateTime},'%y-%m-%d')
            
            
                and date_format(create_time,'%y-%m-%d') <= date_format(#{endCreateTime},'%y-%m-%d')
            
        
    

 

        select c.create_by, count(c.id) as num ,d.`dept_name` as deptName from tb_contract c
            LEFT JOIN `sys_dept` d
            ON c.`dept_id`   = d.`dept_id`
            
            	where c.`create_time` BETWEEN #{indexVo.beginCreateTime} AND #{indexVo.endCreateTime}
            
        GROUP BY c.create_by
        ORDER BY num DESC
        LIMIT 10
