spring-boot-mustache-lombok-demo

Spring Boot demo with Mustache logic less templates integrated with springmvc-mustache.
Lombok is used for simplifing POJOs in project.

How to run demo

mvn clean install
java -jar spring-boot-mustache-demo-0.0.1-SNAPSHOT.jar
go to localhost:8080

How it works

Config

Integrated with springmvc-mustache. It is not standard way but very easy one.

package com.szatmary.peter.mustache.demo.conf;
import com.github.mjeanroy.springmvc.view.mustache.configuration.EnableMustache;
import com.github.mjeanroy.springmvc.view.mustache.configuration.MustacheProvider;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@EnableWebMvc
@EnableMustache(provider = MustacheProvider.AUTO)
@ComponentScan("com.szatmary.peter.mustache.demo")
public class MustacheConfig {
}

Controler

Map<String, Object> model is used implicitly on template site for rendering your java data from controller.

package com.szatmary.peter.mustache.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
import static com.szatmary.peter.mustache.demo.helper.DataHelper.*;
@Controller
public class HelloWorldController {
    @RequestMapping("/")
    public String mustacheDemo(Map<String, Object> model) {
        // one object
        model.put("oneStudent", oneStudent());
        // two objects
        model.put("twoStudents", twoStudents());
        // condition
        model.put("showIt", true);
        // condition
        model.put("neverShowIt", false);
        // no students
        model.put("noStudents", noStudents());
        // emptyList
        model.put("emptyList", emptyList());
        return "demo/helloworld";
    }
}

Student object with Lombok

package com.szatmary.peter.mustache.demo.obj;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@AllArgsConstructor
@NoArgsConstructor
@Data
public class Student {
    private String name;
    private Integer age;
    private Address address;
}

Address object with Lombok

package com.szatmary.peter.mustache.demo.obj;
import lombok.AllArgsConstructor;
import lombok.Data;
@AllArgsConstructor
@Data
public class Address {
    private String address;
}
