I decided to make a project using Mustache + Spring Boot + REST API. Earlier, I used to write projects with the front-end used Java EE + Servlets + JSP. Now I decided to try to switch to Spring and write an application with a front-end. And I found a way to create a page on the front-end using Mustache, but if you use Mustache, then everything needs to be saved to the model , and I want to use REST API. I mean if it is possible? If it's possible I'll be happy if you show a piece of code your RestController and Mustache. The question is 'if possible call endpoint from mustache?'.

Answer 1

Yes, You can create REST API using OpenAPI( https://support.smartbear.com/swaggerhub/docs/tutorials/openapi-3-tutorial.html ) which uses the mustache file to create your code.

You need to add following dependencies,

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>1.6.8</version>
</dependency>
<dependency>
    <groupId>org.openapitools</groupId>
    <artifactId>jackson-databind-nullable</artifactId>
    <version>0.2.2</version>
</dependency>

add the following plugin in the pom.xml for configuration( https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator-maven-plugin/README.md ),

<plugin>
    <groupId>org.openapitools</groupId>
    <artifactId>openapi-generator-maven-plugin</artifactId>
    <version>6.0.0</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <templateDirectory>${project.basedir}/templates
                </templateDirectory>
                <configOptions>
                    //add the configuration options here
                </configOptions>
            </configuration>
        </execution>
    </executions>
</plugin>

By default it uses the mustache files internally to generate codes, you can change the mustache files from the git location( https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/JavaSpring/ )/create your own with the name mentioned in git and place it in the location ${project.basedir}/templates it will generate your codes during the compile time and you can use them in your project.

Place the OpenAPI document in the resource folder where application.properties is placed
