To use Mustache in Spring Boot application, we just need to include spring-boot-starter-mustache dependency and place the template file under src/main/resources/templates/ directory. The rest of the configurations is done automatically by Spring Boot. Also check out our Mustache example with plain MVC.
Example

Mustache Template File
/src/main/resources/templates/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>

<lablel>Bid Price</lablel>

<lablel>Ask Price</lablel>

<lablel>Date</lablel>

<tbody>
{{#todayCurrencyRates}}

</td>
<td>
{{askPrice}}
</td>
<td>
{{bidPrice}}

{{dateTime}}

{{/todayCurrencyRates}}
</tbody>
</table>
</body>
</html>
Spring MVC Controller
@Controller
@RequestMapping("/")
public class MyController {
@RequestMapping
public String handleRequest(Model model) {
model.addAttribute("todayCurrencyRates", getTodayForexRates());
return "forex-view";
}
private List<CurrencyRate> getTodayForexRates() {
//dummy rates
List<CurrencyRate> currencyRates = new ArrayList<>();
LocalDateTime today = LocalDateTime.now();
List<Currency> currencies = new ArrayList<>(Currency.getAvailableCurrencies());
for (int i = 0; i < currencies.size(); i += 2) {
String currencyPair = currencies.get(i) + "/" + currencies.get(i + 1);
CurrencyRate cr = new CurrencyRate();
cr.setCurrencyPair(currencyPair);
cr.setDateTime(today);
BigDecimal bidPrice = new BigDecimal(Math.random() * 5 + 1);
bidPrice = bidPrice.setScale(3, RoundingMode.CEILING);
cr.setBidPrice(bidPrice);
BigDecimal askPrice = new BigDecimal(bidPrice.doubleValue() + Math.random() * 2 + 0.5);
askPrice = askPrice.setScale(3, RoundingMode.CEILING);
cr.setAskPrice(askPrice);
currencyRates.add(cr);
}
return currencyRates;
}
}
Spring boot main class
@SpringBootApplication
public class ExampleMain {
public static void main(String[] args) throws InterruptedException {
SpringApplication.run(ExampleMain.class, args);
}
}
To try examples, run spring-boot maven plugin (configured in pom.xml of example project below):
mvn spring-boot:run We can also run the main class from our IDE.
Output
Example ProjectDependencies and Technologies Used: - Spring Boot 1.5.9.RELEASE
Corresponding Spring Version 4.3.13.RELEASE - spring-boot-starter-mustache : Starter for building MVC web applications using Mustache views.
- JDK 1.8
- Maven 3.3.9
