코드를 메모리에 올려 사용하자

코드를 메모리에 올려 사용하자

 

개발환경 : 스프링 3.0

툴 : 이클립스

DB : 오라클 (상관없음) - 구조는 코드마스터(GRP_CD)와 코드상세 테이블(GRP_CD, CODE)로 이루어져있음

참고 : http://welchsy.tistory.com/289

 

프로젝트를 진행하다 보면 코드성 데이터를 매번 불러오기가 번거롭게 느껴질 때가 많았다. 예전에 사용했던 것이라 조금 지져분 할 수 있으나 커스터마이징해서 사용할 사람만 사용하시길 바란다.

1. *-context 에서 공통코드 조회하는 Bean 세팅

xml : <beans:bean id="codeList" class="서비스경로" />

Java

import java.util.HashMap;

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import com.XXX.model.common.CodeDetail;

import com.XXX.model.common.CodeMaster;

import com.XXX.service.CodeService;

@Controller

public class CodeController {

public static HashMap<String, ArrayList<CodeDetail>> CODE_MAP;

public static String codeResult;

public static ArrayList<CodeMaster> CODE_LIST;

@Autowired

private CodeService codeService;

public CodeController() {}

@PostConstruct

public HashMap<String, ArrayList<CodeDetail>> setCodeList(){  

CODE_MAP = new HashMap<>();

CODE_LIST = codeService.getCodeList();

if(CODE_LIST != null && CODE_LIST.size() > 0){

for(CodeMaster cm : CODE_LIST){

CODE_MAP.put(cm.getGrpCd(), cm.getCodeDetailList());

}

}

return CODE_MAP;

}

/**

* 코드값에 의한 코드명가져오기

* @param grpCd

* @param code

* @return

*/

public String getCodeNameByCode(String grpCd, String code){

codeResult = "";

if(CODE_MAP != null){

ArrayList<CodeDetail> codeList = CODE_MAP.get(grpCd);

if(codeList != null && codeList.size() > 0){

for(CodeDetail bean : codeList){

if(bean.getCode() != null && bean.getCode().equals(code)){

codeResult = bean.getCodeNm();

}

}

}

}

return codeResult;

}

/**

* 코드명에 의한 코드값가져오기

* @param grpCd

* @param codeName

* @return

*/

public String getCodeByCodeName(String grpCd, String codeName){

codeResult = "";

if(CODE_MAP != null){

ArrayList<CodeDetail> codeList = CODE_MAP.get(grpCd);

if(codeList != null && codeList.size() > 0){

for(CodeDetail bean : codeList){

if(bean.getCodeNm() != null && bean.getCodeNm().equals(codeName)){

codeResult = bean.getCode();

}

}

}

}

return codeResult;

}

public ArrayList<String> getComboBoxByCodeList(String grpCd, String value){

ArrayList<String> resultList = new ArrayList<>();

ArrayList<CodeDetail> codeList = CODE_MAP.get(grpCd);

StringBuffer sb = new StringBuffer();

String selChk = "";

if(codeList != null && codeList.size() > 0){

for(CodeDetail bean : codeList){

selChk = "";

if(value != null && value.length() > 0){

if(bean.getCode().equals(value)){

selChk = " selected";

}

}

sb.append("<option value=\""+bean.getCode()+"\""+selChk+" >");

sb.append(bean.getCodeNm());

sb.append("</option>");

resultList.add(sb.toString());

}

}

return resultList;

}

}

 

 

이렇게 세팅하고 서버를 start 하면 공통코드가 static으로 설정된 변수에 담기게 된다.

 

2. 태그라이브러리를 이용하여 커스템태그를 View에서 사용하기

태그라이브러리를 사용하기 위하여 view 상단에 <%@ taglib prefix="tag" tagdir="/WEB-INF/tags"%> 를 삽입한다.

커스텀태그를 생성한다

<%@ tag language="java" pageEncoding="UTF-8"  body-content="empty"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt"%>

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>

<%@ attribute name="type" type="java.lang.String" required="true" description="combo, radio, code, codeNm"%>

<%@ attribute name="id" type="java.lang.String" required="false"%>

<%@ attribute name="name" type="java.lang.String" required="false"%>

<%@ attribute name="style" type="java.lang.String" required="false" description="임의의 style"%>

<%@ attribute name="cls" type="java.lang.String" required="false" description="style의 class"%>

<%@ attribute name="value" type="java.lang.String" required="false" description="콤보박스, 라디오버튼의 선택된 값"%>

<%@ attribute name="defaultTxt" type="java.lang.String" required="false" description="콤보박스 : 초기값"%>

<%@ attribute name="defaultCheck" type="java.lang.Integer" required="false" description="라디오버튼 : default 체크되는 값(1,2,3,4,5...)"%>

<%@ attribute name="code" type="java.lang.String" required="false"%>

<%@ attribute name="codeNm" type="java.lang.String" required="false"%>

<c:set var="codeMap" value="<%=CodeController.CODE_MAP %>" />

<c:choose>

<c:when test="${type eq 'combo'}">

<select id="${id}" name="${name}" class="${cls}" style="${style}">

<c:if test="${defaultTxt != null && fn:length(defaultTxt) gt 0 }">

<option value="" >${defaultTxt}</option>

</c:if>

<c:if test="${fn:length(codeMap[fn:trim(grpCd)]) gt 0}">   

<c:forEach var="result" items="${codeMap[fn:trim(grpCd)]}" varStatus="i">

<c:set var="selChk" value="" />

<c:if test="${result.code eq value}">

<c:set var="selChk" value="selected" />

</c:if>

</c:forEach>

</c:if>

</select>

</c:when>

<c:when test="${type eq 'radio'}">

<c:if test="${fn:length(codeMap[fn:trim(grpCd)]) gt 0}">   

<c:forEach var="result" items="${codeMap[fn:trim(grpCd)]}" varStatus="i">

<c:set var="selChk" value="" />

<c:if test="${i.count eq defaultCheck}">

<c:set var="selChk" value="checked" />

</c:if>

<c:if test="${result.code eq value}">

<c:set var="selChk" value="checked" />

</c:if>

<input type="${type}" id="${id}${i.count}" name="${name}" class="${cls}" style="${style}" value="${result.code}" ${selChk} /> ${result.codeNm}

</c:forEach>

</c:if>

</c:when>

<c:when test="${type eq 'codeNm'}">

<c:if test="${fn:length(codeMap[fn:trim(grpCd)]) gt 0}">   

<c:forEach var="result" items="${codeMap[fn:trim(grpCd)]}" varStatus="i">

<c:if test="${fn:trim(result.code) eq fn:trim(code)}">

${result.codeNm}

</c:if>    

</c:forEach>

</c:if>

</c:when>

<c:when test="${type eq 'code'}">

<c:if test="${fn:length(codeMap[fn:trim(grpCd)]) gt 0}">   

<c:forEach var="result" items="${codeMap[grpCd]}" varStatus="i">

<c:if test="${fn:trim(result.codeNm) eq fn:trim(codeNm) }">

${result.code}

</c:if>    

</c:forEach>

</c:if>

</c:when>

</c:choose>

 

 

해당 태그를 만들고 화면에서 그냥 사용하면 된다.

사용예 

1. COMBO BOX

<tag:code type="combo" grpCd="<%=PengtaiConstants.DISPLAY_STATUS %>" id="sch_dispStatus" name="sch_dispStatus" cls="select_entry01" defaultTxt="전체" value="${noticeParam.sch_dispStatus }" style="width:200px"/> 

2. CODE 명 

<tag:code type="codeNm" grpCd="<%=PengtaiConstants.DISPLAY_STATUS %>" code="${result.dispStatus }"/>

3. RADIO

<tag:code type="radio" grpCd="<%=PengtaiConstants.DISPLAY_STATUS %>" id="dispStatus" name="dispStatus" style="" cls="" defaultCheck="1"/>

 

즐거운 개발하시길 바랍니다~
