我有一个大的数据表，必须在jsp中拆分为更小的表。表格将根据组类型创建。花了数小时试图弄清楚，但无法按照水果类型组过滤jsp中的列表。根据jsp中的一个组将数据拆分为多个html表
@RequestMapping(value = { "dynamicFruitSettings" }, method = RequestMethod.GET)
public ModelAndView getDynamicComponents(Model model) {
LOG.debug("Entering fruit components page");
ModelAndView mav = new ModelAndView();
ArrayList<DynamicFruitSettings> resultList = null;
try {
resultList = (ArrayList<DynamicFruitSettings>) dynamicFruitService.loadAllFruitComponents();
mav.addObject(resultList);
} catch (Exception ex) {
ex.printStackTrace();
}
return new ModelAndView("fruitComponents" , "listFruitComponents", resultList);
}
@Entity
@Table(name = "fruits_components")
public class DynamicFruitSettings {
/** The pk1. */
@Id
@SequenceGenerator(name = "fruits_components_seq", sequenceName = "fruits_components_seq", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "fruits_components_seq")
private Long pk1;
private String fruit_type;
private String component_role;
private Double fruit_wt;
//getters and setters omitted for brevity
示例，演示在JSP中的所有数据
/* DivTable.com */
.divTable {
display: table;
width: 100%;
}
.divTableRow {
display: table-row;
}
.divTableHeading {
background-color: #EEE;
display: table-header-group;
}
.divTableCell,
.divTableHead {
border: 1px solid #999999;
display: table-cell;
padding: 3px 10px;
}
.divTableHeading {
background-color: #EEE;
display: table-header-group;
font-weight: bold;
}
.divTableFoot {
background-color: #EEE;
display: table-footer-group;
font-weight: bold;
}
.divTableBody {
display: table-row-group;
}<div class="divTable">
<div class="divTableHeading"> Fruits</div>
<div class="divTableBody">
<div class="divTableRow">
<div class="divTableCell"> shake</div>
<div class="divTableCell"> 10</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> ice cream</div>
<div class="divTableCell"> 20</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> cake</div>
<div class="divTableCell"> 40</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> candy</div>
<div class="divTableCell"> 5</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> shake</div>
<div class="divTableCell"> 13</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> ice cream</div>
<div class="divTableCell"> 30</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> cake</div>
<div class="divTableCell"> 90</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> candy</div>
<div class="divTableCell"> 25</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> shake</div>
<div class="divTableCell"> 19</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> ice cream</div>
<div class="divTableCell"> 20</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> cake</div>
<div class="divTableCell"> 40</div>
</div>
<div class="divTableRow">
<div class="divTableCell"> candy</div>
<div class="divTableCell"> 15</div>
</div>
</div>
</div>我在jsp最后一下应该像下面
.divTable {
display: table;
width: 100%;
}
.divTableRow {
display: table-row;
}
.divTableHeading {
background-color: #EEE;
display: table-header-group;
}
.divTableCell,
.divTableHead {
border: 1px solid #999999;
display: table-cell;
padding: 3px 10px;
}
.divTableHeading {
background-color: #EEE;
display: table-header-group;
font-weight: bold;
}
.divTableFoot {
background-color: #EEE;
display: table-footer-group;
font-weight: bold;
}
.divTableBody {
display: table-row-group;
}<div class="divTable">
<div class="divTableHeading">Banana</div>

<br>显示所有数据的示例是我目前在jsp中获得的示例。我从我的Controller中获取水果列表，它从db中的水果表中获取数据。由于水果类型可能是任何东西，我不能在基于pk1的水果上做一个简单的“for each”循环，然后做一个“if”从句将其渲染到jsp中。数据库表中的每一行都有一个pk1。
对于如何将它们拆分成更小的表格，您的建议将受到高度赞赏。
可以请你分享你的bean结构和控制器，这样我们就可以知道jsp上会有什么数据。 –
好吧，我将分享实体bean类和控制器代码。 – Sid
此外，如果我可以在jsp中获得唯一组水果类型的列表，以便我可以在for循环中执行if子句来呈现表格，那么我应该更接近解决方案。 – Sid
