Atitit.列表页面and条件查询的实现最佳实践(1)------设置查询条件and提交查询and返回json数据

1. 1. 配置条件字段@Conditional 1 1

2. 2. 配置条件字段显示类型为range----@Conditional(displayType = displayType.rang, rangStart = rang.start, rangEnd = rang.end,op=op.range) 1

3. #----show condition page list 1

4. 提交条件查询表单by dwr 1

5. @filter :: set filter condition use or not use ....or save form .... 2

6. @converter 2

7. #----保存每一个条件map 4 调试 2

8. #====start 2

9. Sigle,range>>>> wehere cause 2

10. Hb pageing 2

11. Ret page map 2

12. #----code 3

13. 参考 5

1. 1. 配置条件字段@Conditional 1

2. 2. 配置条件字段显示类型为range----@Conditional(displayType = displayType.rang, rangStart = rang.start, rangEnd = rang.end,op=op.range)

或者dispayType.single..

3. #----show condition page list

4. 提交条件查询表单by dwr

//queryBtn_click

Query(1)

function query(isResetPage1)

{

if(isResetPage1==1)

resetPageTo1();

var mp=dwr.util.getFormValues("formx");

elmtC.findByPropertyss_page(mp ,function(data){

//alert("保存成功");

bindTableData(data.rows);

setPageInfo({"total":data.total,"pageSize":10});

});

}

5. @filter :: set filter condition use or not use ....or save form ....

6. @converter

7. #----保存每一个条件map 4 调试

filex.save_safe( core.toJsonStr(QueryPropertyssMap) , "c:\\json2.txt");

8. #====start

for (Field fld : flds) {

Conditional cdt = fld.getAnnotation(Conditional.class);

if (cdt == null)

continue;

.......

9. Sigle,range>>>> wehere cause

10. Hb pageing

11. Ret page map

Map mp=new HashMap();

mp.put("total" ,SafeVal.val( threadLocal_rowsCount.get(),list_sub.size()));

mp.put("rows",list_sub);

12. #----code

public List findByPropertyss(Map QueryPropertyssMap) {

// log.debug("finding GvMaterial instance with property: " +

// propertyName + ", value: " + value);

core. log("---o720--");

core.logMap(QueryPropertyssMap);

filex.save_safe( core.toJsonStr(QueryPropertyssMap) , "c:\\json2.txt");

String propertyName;

Object value;

Criteria c = getSession().createCriteria(GvMaterial.class);

Field[] flds = GvMaterial.class.getDeclaredFields();

for (Field fld : flds) {

try {

String fldName = fld.getName();

if (fldName.startsWith("playtime")) {

String s = "";

}

if (!includeFldInfoPostMap(QueryPropertyssMap, fldName))

continue;

Conditional cdt = fld.getAnnotation(Conditional.class);

if (cdt == null)

continue;

if (cdt.adptr() != None.class) // cstm mode

//

{

List li = adptrMOde(QueryPropertyssMap, c, fld, fldName,

cdt);

addExpresss(c, li);

} else if (cdt.displayType().equals(displayType.single)) {

// if

// (fld.getType().getName().equals(String.class.getName()))

// {

List<Criterion> exprsLi = getExprs(fldName, cdt.op(),

QueryPropertyssMap);

core.log(String.format("--o7f1: dbg fldinfo: %s---%s ",

fldName, QueryPropertyssMap.get(fldName)));

addExpresss(c, exprsLi);

QueryPropertyssMap);

core.log(String.format("--o7f1: dbg fldinfo: %s---%s ",

addExpresss(c, exprsLi);

}

//

} catch (Exception e) {

core.log(e);

}

// c.add(Restrictions.eq("aname",name));//eq是等于，gt是大于，lt是小于,or是或

}

c.addOrder(Order.desc("materialId"));

List<GvMaterial> list = c.list();

threadLocal_rowsCount.set(list.size());

Object page = QueryPropertyssMap.get("page_page");

List<GvMaterial> list_sub = PagingUtil.getList(list,

QueryPropertyssMap.get("pagesize"), page);

return list_sub;

}
