一、平台放款
1、需求描述
标的募资时间到,平台会操作放款或撤标,如果达到放款条件则操作放款
说明:撤标过程与放款过程一致,处理业务相对简单,只是将出借金额返回给出借人即可,可以自行完成
2、相关数据库表
还款人还款记录:lend_return
投资人回款记录:lend_item_return
3、参考文档
参考《汇付宝商户账户技术文档》3.11满标放款
二、具体步骤
step1:放款
放款是一个同步接口,如果放款返回成功,那么我们要处理平台业务
step2:处理业务如下
(1)标的状态和标的平台收益
(2)给借款账号转入金额
(3)增加借款交易流水
(4)解冻并扣除投资人资金
(5)增加投资人交易流水
(6)生成借款人还款计划和出借人回款计划
管理平台放款
1、Controller
AdminLendController
代码语言:javascript复制@ApiOperation("放款")
@GetMapping("/makeLoan/{id}")
public R makeLoan(
@ApiParam(value = "标的id", required = true)
@PathVariable("id") Long id) {
lendService.makeLoan(id);
return R.ok().message("放款成功");
}
2、满标放款
接口:LendService
代码语言:javascript复制/**
* 满标放款
* @param lendId
*/
void makeLoan(Long lendId);
实现:LendServiceImpl
代码语言:javascript复制@Resource
private UserInfoMapper userInfoMapper;
@Resource
private UserAccountMapper userAccountMapper;
@Resource
private LendItemService lendItemService;
@Resource
private TransFlowService transFlowService;
@Transactional(rollbackFor = Exception.class)
@Override
public void makeLoan(Long lendId) {
//获取标的信息
Lend lend = baseMapper.selectById(lendId);
//放款接口调用
Map<String, Object> paramMap = new HashMap<>();
paramMap.put("agentId", HfbConst.AGENT_ID);
paramMap.put("agentProjectCode", lend.getLendNo());//标的编号
String agentBillNo = LendNoUtils.getLoanNo();//放款编号
paramMap.put("agentBillNo", agentBillNo);
//平台收益,放款扣除,借款人借款实际金额=借款金额-平台收益
//月年化
BigDecimal monthRate = lend.getServiceRate().divide(new BigDecimal(12), 8, BigDecimal.ROUND_DOWN);
//平台实际收益 = 已投金额 * 月年化 * 标的期数
BigDecimal realAmount = lend.getInvestAmount().multiply(monthRate).multiply(new BigDecimal(lend.getPeriod()));
paramMap.put("mchFee", realAmount); //商户手续费(平台实际收益)
paramMap.put("timestamp", RequestHelper.getTimestamp());
String sign = RequestHelper.getSign(paramMap);
paramMap.put("sign", sign);
log.info("放款参数:" JSONObject.toJSONString(paramMap));
//发送同步远程调用
JSONObject result = RequestHelper.sendRequest(paramMap, HfbConst.MAKE_LOAD_URL);
log.info("放款结果:" result.toJSONString());
//放款失败
if (!"0000".equals(result.getString("resultCode"))) {
throw new BusinessException(result.getString("resultMsg"));
}
//更新标的信息
lend.setRealAmount(realAmount);
lend.setStatus(LendStatusEnum.PAY_RUN.getStatus());
lend.setPaymentTime(LocalDateTime.now());
baseMapper.updateById(lend);
//获取借款人信息
Long userId = lend.getUserId();
UserInfo userInfo = userInfoMapper.selectById(userId);
String bindCode = userInfo.getBindCode();
//给借款账号转入金额
BigDecimal total = new BigDecimal(result.getString("voteAmt"));
userAccountMapper.updateAccount(bindCode, total, new BigDecimal(0));
//新增借款人交易流水
TransFlowBO transFlowBO = new TransFlowBO(
agentBillNo,
bindCode,
total,
TransTypeEnum.BORROW_BACK,
"借款放款到账,编号:" lend.getLendNo());//项目编号
transFlowService.saveTransFlow(transFlowBO);
//获取投资列表信息
List<LendItem> lendItemList = lendItemService.selectByLendId(lendId, 1);
lendItemList.stream().forEach(item -> {
//获取投资人信息
Long investUserId = item.getInvestUserId();
UserInfo investUserInfo = userInfoMapper.selectById(investUserId);
String investBindCode = investUserInfo.getBindCode();
//投资人账号冻结金额转出
BigDecimal investAmount = item.getInvestAmount(); //投资金额
userAccountMapper.updateAccount(investBindCode, new BigDecimal(0), investAmount.negate());
//新增投资人交易流水
TransFlowBO investTransFlowBO = new TransFlowBO(
LendNoUtils.getTransNo(),
investBindCode,
investAmount,
TransTypeEnum.INVEST_UNLOCK,
"冻结资金转出,出借放款,编号:" lend.getLendNo());//项目编号
transFlowService.saveTransFlow(investTransFlowBO);
});
//放款成功生成借款人还款计划和投资人回款计划
// TODO
}
3、根据lendId获取投资记录
接口:LendItemService
代码语言:javascript复制List<LendItem> selectByLendId(Long lendId, Integer status);
实现:LendItemServiceImpl
代码语言:javascript复制@Override
public List<LendItem> selectByLendId(Long lendId, Integer status) {
QueryWrapper<LendItem> queryWrapper = new QueryWrapper();
queryWrapper.eq("lend_id", lendId);
queryWrapper.eq("status", status);
List<LendItem> lendItemList = baseMapper.selectList(queryWrapper);
return lendItemList;
}
前端整合
srb-admin
1、定义api
创建 src/api/core/lend.js
代码语言:javascript复制 makeLoan(id) {
return request({
url: `/admin/core/lend/makeLoan/${id}`,
method: 'get'
})
}
2、页面模板
src/views/core/lend/list.vue
代码语言:javascript复制<el-button v-if="scope.row.status == 1" type="warning" size="mini" @click="makeLoan(scope.row.id)">
放款
</el-button>
3、页面脚本
src/views/core/lend/list.vue
代码语言:javascript复制makeLoan(id) {
this.$confirm('确定放款吗?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
})
.then(() => {
return lendApi.makeLoan(id)
})
.then(response => {
//放款成功则重新获取数据列表
this.fetchData()
this.$message({
type: 'success',
message: response.message
})
})
.catch(error => {
console.log('取消', error)
if (error === 'cancel') {
this.$message({
type: 'info',
message: '已取消放款'
})
}
})
}
