我有一个要求，我需要在速度模板中生成动态表。
我在java代码下面我正在准备一个hashmap。输入将来自外部应用程序。
public String generateFileFromStringTemplate(HashMap<String, Object> documentContentHashmap, String templateString,TWList list){
System.out.println("hashmap : "+list.getArraySize());
TWObject obj=null;
Map<String, Map<String,String>> mapobj=new HashMap<>();
try{
TemplateUtility tutility = new TemplateUtility();
obj = TWObjectFactory.createObject();
for (int i = 0; i < list.getArraySize(); i++) {
obj=(TWObject) list.getUnmodifiableArray().get(i);
Object[]s=obj.getPropertyNames().toArray();
Map<String, String> map1=new HashMap<>();
for (int j = 0; j < obj.getPropertyNames().toArray().length; j++) {
map1.put(s[j].toString(),(String) obj.getPropertyValue(s[j].toString()));
}
mapobj.put("Map"+i, map1);
}
documentContentHashmap.put("Map", mapobj);
StringWriter strWriter = tutility.generateTemplateFromString(documentContentHashmap, templateString);
String documentBytes = tutility.generateDocsEncodedToBase64Content(strWriter);
if (documentBytes != null) {
return documentBytes;
}
return null;
}
catch (Exception e){
e.printStackTrace();
return e.getMessage();
}
}
}
下面是我将documentContentHashmap传递给velocity模板引擎的代码。
StringWriter generateTemplateFromString(HashMap<String, Object> documentContentHashmap, String templateString)
{
try
{
RuntimeServices runtimeServices = RuntimeSingleton.getRuntimeServices();
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy_HHmmss");
String fileName = "StrTemplate_" + sdf.format(date) + ".html";
StringReader reader = new StringReader(templateString);
SimpleNode node = runtimeServices.parse(reader, fileName);
Template template = new Template();
template.setRuntimeServices(runtimeServices);
template.setData(node);
template.initDocument();
VelocityContext context = new VelocityContext();
Set<String> sourceKeySet = documentContentHashmap.keySet();
System.out.println("sourceKeySet : "+sourceKeySet);
for (String key : sourceKeySet) {
System.out.println("documentContentHashmap.get(key) : "+documentContentHashmap.get(key));
context.put(key, documentContentHashmap.get(key));
}
StringWriter writer = new StringWriter();
template.merge(context, writer);
return writer;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
以下是从上面的代码生成的示例数据。
{Map0={interestRate=3, tenor=2 sal, proposedLimit=555, loanType=PL, approvedLimit=556, loanAmount=554, loanRepaymentDate=AAJ}, Map1={interestRate=1, tenor=3 sal, proposedLimit=445, loanType=HL, approvedLimit=446, loanAmount=444, loanRepaymentDate=KAL}}
下面是我的html，我在迭代地图并尝试将上面的数据显示为2行，但我无法实现所以所有数据只显示在一行中。
<html>
<head>
<style type="text/css">
td,th{font-family:Arial, "Helvetica Neue", Helvetica, sans-serif;font-size:12px ;}
.PaymentVoucher{
font-size:15px;
text-align:center;
letter-spacing: 3px;
}
</style>
</head>
<body>
<div>
<table style="width:100%; border: 1px solid #dddddd; font-family: Times New Roman, Times, sans-serif;">
<tr>
<td colspan="2">
<label><b></b></label>
</td>
<td style="width:20%;">
<span>Customer Name : $pvMap.get('customer_name')</span><br/>
</td>
</tr>
<tr>
<td style="width:20%;">
<br />
<label>Page :</label><span>1 of 1</span>
</td>
</tr>
<tr>
<td colspan="4" class="PaymentVoucher"><b>Loan Details </b></td>
</tr>
<tr>
<td>
<label style="width:450px;">Loan Application Date : </label><span>$pvMap.get('application_date')</span>
</td>
<td colspan = "3"></td>
</tr>
</table>
<br />
<table style="width:100%; border: 1px solid #dddddd; font-family: Times New Roman, Times, sans-serif;">
<tr>
<th>Loan Type</th><th>Loan Amount</th><th>Interest Rate</th><th>Loan Repayment Date</th><th>Tenor</th><th>Proposed Limit</th><th>Approved Limit</th>
</tr>
<tr>
#set($str1="loanType")
#set($str2="loanAmount")
#set($str3="interestRate")
#set($str4="loanRepaymentDate")
#set($str5="tenor")
#set($str6="proposedLimit")
#set($str7="approvedLimit")
#foreach ($mapEntry in $Map.entrySet())
#foreach ($map1 in $mapEntry.getValue().entrySet())
#if($map1.key==$str1)
<td>$map1.getValue()</td>
#end
#end
#end
</tr>
</table>
<br />
<br />
<span>Regards,</span><BR/>
<span>Test</span><BR/>
</div>
</body>
</html>
有人可以帮忙吗？提前致谢。
尝试在第一个循环中移动第二个<tr>标记（并使用map getter而不是循环遍历条目，这就是为地图制作的地图）：
<table style="width:100%; border: 1px solid #dddddd; font-family: Times New Roman, Times, sans-serif;">
<tr>
<th>Loan Type</th><th>Loan Amount</th><th>Interest Rate</th><th>Loan Repayment Date</th><th>Tenor</th><th>Proposed Limit</th><th>Approved Limit</th>
</tr>
#set($columns = ["loanType", "loanAmount", "interestRate", "loanRepaymentDate", "tenor", "proposedLimit", "approvedLimit"])
#foreach ($subMap in $Map.values())
<tr>
#foreach ($column in $columns)
<td>$subMap.get($column)</td>
#end
</tr>
#end
</table>
