Vertx 实现webapi实战项目(五)

添加测试handler

一：定义上传json，注意，mId是必须的。

1 {
2   "mId": 101,
3   "name":"cddd",
4   "age":23
5 }

二：新建上传json解析类，继承上传抽象类AbstractUpMessage。

public class DemoRequest extends AbstractUpMessage {
    public String name;
    public int age;

    @Override
    protected void decodeBody() {
        name = bodyData.getString("name","");
        age = bodyData.getInteger("age",0);
    }
}

三：定义返回json

{
    "mId": 101,
    "code": 200,
    "name":"res",
    "info":"ininii"
}

四：定义返回编码类，继承AbstractDownMessage

public class DemoResponse extends AbstractDownMessage {
    private String name;
    private String info;

    public DemoResponse(short mId,String name,String info){
        messageId = mId;
        this.name = name;
        this.info = info;
    }

    @Override
    protected void encodeBody() {
        bodyData.put("name",name);
        bodyData.put("info",info);
    }
}

五，定义handler，实现接口 InterHandler

 1 public class DemoHandler implements InterHandler {
 2     @Override
 3     public void handler(AbstractUpMessage up, HttpServerResponse resp) {
 4         //上传参数
 5         DemoRequest request = (DemoRequest)up;
 6         System.out.println("上传参数:"+ request.name + "-" + request.age);
 7
 8         //返回数据
 9         String n = "cscscs---";
10         String in = "info ---";
11         //编码返回json
12         DemoResponse response = new DemoResponse(getMessageId(),n,in);
13         response.encode();
14         resp.end(response.SendMessage());
15     }
16
17     @Override
18     public short getMessageId() {
19         return HandlerCode.DEMO_V1;
20     }
21 }

六：加载handler。定义一个配置类Configure，初始化handler

public class Configure {
    private static final Configure ourInstance = new Configure();

    public static Configure getInstance() {
        return ourInstance;
    }

    public void init(){
        initHandler();
    }

    private void initHandler(){
        HandlerManager.getInstance().addHandler(new DemoHandler());
    }
}

修改OnlineServer主函数，加载configure。

   public static void main(String[] args){
        Configure.getInstance().init();

        VertxOptions vertxOptions = new VertxOptions();
        Vertx vertx = Vertx.vertx(vertxOptions);

        //部署http服务器
        vertx.deployVerticle(HttpServerVerticle.class.getName(),
                new DeploymentOptions().setInstances(VertxOptions.DEFAULT_EVENT_LOOP_POOL_SIZE), res -> {
            if(res.succeeded()){
                logger.warn("服务端部署成功----");
            }else {
                logger.error("服务端部署失败---" + res.cause());
            }
        });
    }

七：修改 MessageRecognizer 添加解码json的类

public class MessageRecognizer implements IMessageRecognizer {
    @Override
    public MessageFactory recognize(short messageId) {
        switch (messageId){
            case HandlerCode.DEMO_V1: return new DemoRequest();
            default:return null;
        }
    }
}

八：启动服务，调用接口试试

成功！！！！
