如何使用Java在Oracle中插入序列化数据

Question

I have some list value get from database and saved this value with checked and unchecked (1 or 0)

My HTML markup is:

  <div class="panel-body">
  <form action="" id = "buindEligibilityData">
    <table class="table">
        <s:iterator value="eligibilityList" status="status">
         <s:if test='%{lkpGroupId == "160100000005"}'>
            <tr id="eligibilityTrDiv">
         <td><input type="hidden" value="160100000005" name="gropuId"></td><td><input type="hidden" value="<s:property value='lkpDataName' />" name="lkpName"></td> <td><input type="hidden" value="<s:property value='lkpDataId' />" name="lkpDataId"></td><td > <s:property value='lkpDataName' /></td>
          <td> <div class="example"><div>
          <s:if test='%{chackBoxStatus == "1"}'>
          <input value="1" id="hid_<s:property value='lkpDataId' />" type="hidden" name="checkbox1"/>
          <input id="<s:property value='lkpDataId' />" class="chackBoxIdPrefix" type="checkbox" name="lkpDataIdcheckbox"  checked="checked">

          </s:if>
          <s:else>
          <input value="0" id="hid_<s:property value='lkpDataId' />" type="hidden" name="checkbox1"/>
           <input id="<s:property value='lkpDataId' />" class="chackBoxIdPrefix" type="checkbox" name="lkpDataIdcheckbox" >

          </s:else>
          <label for="checkbox2"><span></span>bind For Prefix</label></div></div></td>
          </tr>
        </s:if>
     </s:iterator>

        <tr><td colspan="3" align="center"> <input type="button" value="Save Change" class="btn-info" align="middle" onclick="buindDataForPrefix()"> </td></tr>
          </table>
    </form>
  </div>

onclick function:

function buindDataForPrefix() {     
    var form_data = $jq("#buindEligibilityData").serialize();

    $jq.ajax({
                    type: 'post',
                    data:form_data, 
                    mimeType:"multipart/form-data",                 
                    url: "buindEligibilityDataAdmissionInfo.do",
                    success: function(data){                        
                        $jq("#eligibilityTrDiv").html(data);                                                            
                    },
                    complete: function(data){   

                    }                       
          });
}

Java code:

 public String buindEligibilityData() {
    String[] logInInfo = (String[]) ActionContext.getContext().getSession()
            .get(sessionVariable.getUserLogInInfo());
    String doctorEmpId = logInInfo[1].toString();
    String companyNo = logInInfo[4].toString();
    String getLkpDataIdPrefix = (String) ActionContext.getContext().getSession().get(sessionVariable.getLkpPrefixDataId());

    System.out.println(lkpDataId);
    System.out.println(lkpDataIdcheckbox);
    String lkpDataIdArr[]=lkpDataId.split(",");
    String lkpDataIdcheckboxArr[]=lkpDataIdcheckbox.split(","); 
    System.out.println(lkpDataIdArr.length);
    System.out.println(lkpDataIdcheckboxArr.length);
    System.out.println("lkpDataIdPrefixpp"+getLkpDataIdPrefix);
    System.out.println("gropuId"+gropuId);


    patientProgressNoteSql.savebuindEligibilityData(gropuId, getLkpDataIdPrefix ,lkpDataId, lkpDataIdcheckbox, companyNo , doctorEmpId, lkpName);
    return "buindEligibilityData";
}

SQL code:

Answer 1

The loop iterates from 0 to a length of CHACK_STATUS (which is a string)

 for (int i = 0; i < CHACK_STATUS.length(); i++)

then inside the loop this tring is splitted into a table of elements

String lkpDataIdcheckboxArr[] = CHACK_STATUS.split(",");

and then the code is retrieving value from this table here:

if(lkpDataIdcheckboxArr[i].trim().equals("1")){

and also here:

  + lkpDataIdcheckboxArr[i] + "')";     

---

Now imagine that CHACK_STATUS = "1,0,1"

A length of this variable is: CHACK_STATUS.length() = 5.

If you split this string: lkpDataIdcheckboxArr[] = CHACK_STATUS.split(",") you will get a table with 3 elements: lkpDataIdcheckboxArr[] = {"1","0","1"}

Now the loop is iterating ( i < 5) : 0 ... 1 ... 2 .... 3

and BANG - if(lkpDataIdcheckboxArr[i].trim().equa...
for i=3 throws IndexOutOfBoundException because lkpDataIdcheckboxArr has only 3 elements [0], [1] and [2], the element [3] does not exists !
