Question

List<map>转list<javaBean> ,程序里写的是List<javaBean>不知道为啥变成list<map>了。。

public DrJfDepartmentcost saveDeptMC(List<DrJfDepartmentcost> departmentCost) { DrJfDepartmentcost drJfDepartmentcost = new DrJfDepartmentcost(); for(int i=0;i<departmentCost.size();i++){ //BigDecimal cstotalcos = departmentCost.get(i).getCloudservicedate(); BigDecimal dmc = (BigDecimal)departmentCost.get(i).getCloudservicesum(); System.out.println(dmc); } departMCDAO.saveDeptMC(drJfDepartmentcost); return drJfDepartmentcost; }

Answer 1

你是传入的参数有问题吧，List<DrJfDepartmentcost> departmentCost
这是要你传一个这样的List对象进来
