【汇智学堂】-AJAX+JAVA之二（新增数据Servlet+DAO）

Servlet文件中的方法：

if (dos.equals("add")) {

            String projectname = request.getParameter("projectname");
            String investor = request.getParameter("investor");
            String investdate = request.getParameter("investdate");
            String money = request.getParameter("money");
            String useforwhat = request.getParameter("useforwhat");
            String classification=request.getParameter("classification");
            Inout investment=new Inout(0,projectname,investor,investdate,money,useforwhat,classification);
            String rep = "";
            if(inoutDao.add(investment)>0){
                rep="1";
                out.print(rep);
            }
            else {
                rep="0";
                out.print(rep);
            }
        }

接口中新增：

public  int add(Inout inout);

实现类中的方法：

public  int add(Inout inout){
        int num = 0;
        //String sql = "insert into users(name,age) values(?,?)";
        String sql="INSERT into tb_inout(projectname,investor,investdate,money,useforwhat,classification) values(?,?,?,?,?,?)";
        try {
            num = executeUpdate(sql,inout.getProjectname(),inout.getInvestor(),inout.getInvestdate(),inout.getMoney(),inout.getUseforwhat(),inout.getClassification());
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return num;
    }
