Question

我想在commit.where之前放置if else或switch语句更适合检查员工数量。我把我的if else或switch代码。如果计数为5，我希望限制员工，然后显示消息“达到最大员工限制”，否则允许提交。我是java的新人plz有人帮我解决这个问题

    public String cmdSave_action()

{
    // my code before 

    {
    DeptSet result;
       try {
           dbo.connect();

           result = 
                   dbo.execSQL("select count(*) from empmasterinfo where mainid='ORGElement' and designationid='?') "
                               (inputText_ORGElement.getValue() != null ? 
             ""));

        result = dbo.execSQL(sSQL);

      catch (Exception e) {
    System.out.println(e.getMessage());
       finally 
       {
       dbo.close();                         
       }
       return null;
    }}}

    // my code above

  {  
    Global.PerformIteratorAction(this.bindings, "Commit");
    AdfFacesContext afContext = AdfFacesContext.getCurrentInstance();
    afContext.getProcessScope().put("EmployeeID", 
                                    Global.getCurrRowFieldValue("EmpmasterinfoViewIterator", 
                                                                "Employeeid"));
    if (afContext.getProcessScope().get("AddEdit").toString().equals("0"))

    {
        Global.PerformIteratorAction(this.bindings, 
                                     "EPR_TRANSFER_APPLICANT_INFO");
        Global.PerformIteratorAction(this.bindings, "eprGenerateApPlan");
    }
    return null;
}}

Answer 1

请正确关闭try catch阻止

try{

}catch(Exception e){

}finally{

}

阅读this

Answer 2

catch和finally位于try block

之内

try {
//code
}
catch(Exception e) {
System.out.println(e.getMessage());
}
finally {
dbo.close();
}

Answer 3

使用IDE可以帮助您在编写代码时进行缩进和正确格式化。例如Eclipse。

对于第一个错误，请关闭try-catch块对于第二个错误：由于您的方法声明为public String cmdSave_action()，因此您应该在方法的末尾返回String值。您的代码中缺少return语句。

提交前单击保存按钮后的java检查条件
