Extending JettyMicroservice

This example shows how the JettyMicroservice class can be extended to implement lifecycle listener methods or override existing methods. We'll create a new class com.foo.MyJettyMicroservice.

/**
* Sample subclass of a JettyMicroservice that provides customized behavior.
*/
public class MyJettyMicroservice extends JettyMicroservice {

    public static void main(String[] args) throws Exception {
        JettyMicroservice.Builder builder = JettyMicroservice.create();
        new MyJettyMicroservice(builder).start().join();
    }

    public MyJettyMicroservice(JettyMicroservice.Builder builder) throws Exception {
        super(builder);
    }

    // Customized code here.

Optionally, you can extend the JettyMicroservice.Builder class as well:

public class MyJettyMicroservice.Builder extends JettyMicroservice.Builder {

    int extraField;

    /**
    * Constructor (required).
    */
    protected MyJettyMicroservice.Builder() {}

    /**
    * Copy constructor (required).
    *
    * @param copyFrom The builder to copy settings from.
    */
    protected MyJettyMicroservice.Builder(MyJettyMicroservice.Builder copyFrom) {
        super(copyFrom);
    }

    // Additional setters

    public MyJettyMicroservice.Builder extraField(int extraField) {
        this.extraField = extraField;
        return this;
    }

    // Overridden methods

    @Override /* JettyMicroservice.Builder */
    public MyJettyMicroservice.Builder copy() {
        return new MyJettyMicroservice.Builder(this);
    }

    @Override /* JettyMicroservice.Builder */
    public MyJettyMicroservice.Builder ports(int...ports) {
        super.ports(ports);
        return this;
    }

    @Override /* JettyMicroservice.Builder */
    public MyJettyMicroservice.Builder servlet(Class cls) throws InstantiationException, IllegalAccessException {
        super.servlet(cls);
        return this;
    }

    ...
}
