Spring Controller
@Controller
@RequestMapping("/")
public class CurrencyRateController {
@RequestMapping
public String handleRequest(Model model) {
model.addAttribute("todayCurrencyRates", getTodayForexRates());
return "forex-view";
}
.............
}
public class CurrencyRate {
private String currencyPair;
private LocalDateTime dateTime;
private BigDecimal askPrice;
private BigDecimal bidPrice;
.............
}
Mustache template:
src/main/webapp/WEB-INF/views/forex-view.html<html>
<head>
<style>
table {
border-collapse: collapse;
width:100%;
}
table, td, th {
border: 1px solid #999;
padding: 5px;
}
</style>
</head>
<body>
<h2>Currency Rates</h2>
<table>
<thead>
<tr>
<th>
<lablel>Currency Pair</lablel>
</th>
<th>
<lablel>Bid Price</lablel>
</th>
<th>
<lablel>Ask Price</lablel>
</th>
<th>
<lablel>Date</lablel>
</th>
</tr>
</thead>
<tbody>
{{#todayCurrencyRates}}
<tr>
<td>
{{currencyPair}}
</td>
<td>
{{askPrice}}
</td>
<td>
{{bidPrice}}
</td>
<td>
{{dateTime}}
</td>
</tr>
{{/todayCurrencyRates}}
</tbody>
</table>
</body>
</html>
To try examples, run embedded tomcat (configured in pom.xml of example project below):
mvn tomcat7:run-war Output
