Spring Boot 使用DAO层不使用xml直接进行数据访问

  一般我们开发Spring boot的web应用的时候，一般会实现Service接口，然后实现对应的类，调用方法，通过对DAO映射进行数据访问，我现在就说一下如何实现简单快速的实现数据的访问。通过对DAO层直接进行数据的访问.

@Results({
        @Result(column = "id",property = "id")
})

@SelectProvider(type = SqlProvider.class,method = "queryReceivableForm")
List<ReceivableForm> queryReceivableForm(Map<String, Object> map);

class SqlProvider{
    public String queryReceivableForm(Map<String,Object> map){
        String sql = new SQL(){
            {
                SELECT("id,settlement_cycle,tc_code,insurance_name,payment_channel,amount_receivable,refund_amount," +
                        "net_settlement,actual_amount_received,amount_paid,net_amount");
                FROM("t_insurance_collection");
                WHERE("batch_no = #{batchNo}");
                WHERE("archive_flag = '1'");
                if(!StringUtils.isEmpty(map.get("paymentChannel")))
                {
                    WHERE("payment_channel = #{paymentChannel}");
                }
            }
        }.toString();
        if (map.get("offset")!=null&&map.get("limit")!=null){
            sql += "limit #{offset},#{limit}";
        }
        return sql;
    }
