如何使用spring mvc将数据从控制器显示到jsp? [英] how to display data from controller to jsp using spring mvc?
问题描述
您好,我无法在春季显示控制器到jsp页面的数据,刚到春天,这是我的控制器
列表与LT; DocDto> list = DocService.getDocs();
DocDto docList = new DocDto();
docList.setdocType(doc_type);
docList.setdocSubType(doc_subtype);
jobList.setTransactionId(transaction_id);
model.addAttribute(docList,docList);
这是我的jsp表格
< c:forEach var =oitems =$ {list}>
< tr>
< td>
< c:out value =$ {o.doc_type}/>< / td>
< td>< c:out value =$ {o.doc_subtype}/>< / td>
< / td>
< / tr>
这不会在我的jsp中显示任何数据,只是简单地显示它的空白表。任何帮助,将不胜感激。
代替$ {list}在每个循环中使用$ {docList}。
如果没有成功,请按照以下步骤操作:
检查您是否在jsp中包含了适当的jstl库
<%@ taglib uri =http://java.sun.com/jsp/jstl/coreprefix =c%>
并为jstl库使用适当的jar。
检查DocDto是否有doc_type,doc_subtype变量是否拼写正确。
Hi I am unable to display data from controller to jsp page in spring, am new to spring, this is my controller
List<DocDto> list =DocService.getDocs();
DocDto docList = new DocDto();
docList.setdocType(doc_type);
docList.setdocSubType(doc_subtype);
jobList.setTransactionId(transaction_id);
model.addAttribute("docList", docList);
This is my jsp table
<c:forEach var="o" items="${list}">
<tr>
<td>
<c:out value="${o.doc_type}" /></td>
<td><c:out value="${o.doc_subtype}" /></td>
</td>
</tr>
This is not displaying any data in my jsp, just simply blank table it is displaying. Any help would be appreciated.
Instead of ${list} use ${docList} in for each loop. If it did not works then follow following steps :
Check you included proper jstl library in jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
and using proper jar for jstl library.
Check DocDto for doc_type,doc_subtype variables properly spelled or not.
