Spring-Web的好处是，快速上手、快速成型，且成熟稳定无Bug。

但对于个人而言，这套框架太重了。由此探寻更好的轻量Web框架Jooby！

本文源码地址meethigher/jooby-example: 基于Netty的轻量级Web框架Jooby使用示例

一、搭建项目

创建原生maven空项目，引入依赖

<dependency><groupId>io.jooby</groupId><artifactId>jooby-netty</artifactId><version>2.16.1</version>
</dependency>
<dependency><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId><version>1.2.12</version>
</dependency>

创建启动类

import io.jooby.Jooby;public class Application extends Jooby {//构造函数快{get("/", ctx -> "Hello World");}public static void main(String[] args) {runApp(args, Application.class);}
}

二、配置文件

Jooby同样支持解析多种类型的配置文件，只记录常用的application.conf

Jooby读取配置文件优先级顺序

1. 优先应用根目录下。即System.getProperty("user.dir")
2. 其次类路径下，即resources下或者jar包内的。

resources添加application.conf

server.port = 8080
app.name = "内部"
database.url = "jdbc:mysql://localhost:3306/mydb"

示例接口

import io.jooby.Jooby;
import io.jooby.MediaType;import java.nio.charset.StandardCharsets;public class Application extends Jooby {//构造函数快{// use Decorator.decorator(next -> ctx -> {// get response content-type.final MediaType responseType = ctx.getResponseType();// if content-type is text-specificif(responseType.isTextual())// override response type with current media type and always use UTF-8 charset!ctx.setResponseType(responseType, StandardCharsets.UTF_8);// pipe next response procedure.return next.apply(ctx);});get("/", ctx -> {String appName = getConfig().getString("app.name");return "Welcome to " + appName;});get("/database", ctx -> {String dbUrl = getConfig().getString("database.url");return "Database URL: " + dbUrl;});}public static void main(String[] args) {runApp(args, Application.class);}
}

三、开发接口

3.1 Script API-仅支持简单路由

Script API 通常用于编写小型的、单一用途的路由处理器。

支持占位符路由规则，但是像拼参形式的就不支持。

import static io.jooby.Jooby.runApp;public class ScriptAPIApplication {public static void main(String[] args) {//consumer函数式接口简写runApp(args, app -> {app.get("/param/{id}", ctx -> {String id = ctx.path("id").value();return id;});app.post("/param/{id}", ctx -> {return ctx.path("id").value();});});}
}

3.2 MVC API-支持复杂路由

添加依赖

<!-- MVC API 核心模块 -->
<dependency><groupId>io.jooby</groupId><artifactId>jooby-apt</artifactId><version>2.16.1</version>
</dependency>
<!-- json模块 -->
<dependency><groupId>io.jooby</groupId><artifactId>jooby-gson</artifactId><version>2.16.1</version>
</dependency>

创建controller

import io.jooby.MediaType;
import io.jooby.Multipart;
import io.jooby.annotations.*;import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;@Path("/mvc")
public class Controller {@GET("/get")public String get() {return "Hello World";}@GET("/pathParam/{id}")public String pathParam(@PathParam String id) {return id;}@GET("/queryParam")public String queryParam(@QueryParam String id, @QueryParam String name) {return name + "--->" + id;}/*** form表单,支持两种形式* application/x-www-form-urlencoded，不支持文件* multipart/form-data，支持文件*/@POST("/formParam")public String formParam(@FormParam String name, @FormParam String age, @FormParam Multipart file) {if (file != null) {try (InputStream is = file.file("file").stream(); FileOutputStream fos = new FileOutputStream("test.txt")) {int b;while ((b = is.read()) != -1) {fos.write(b);}fos.flush();} catch (IOException e) {}}return name + "--->" + age;}@POST("/bodyParam")@Consumes(MediaType.JSON)//可省略@Produces(MediaType.JSON)//可省略public Object bodyParam(Object body) {return body;}@POST("/pageQuery")public String pageQuery(PageRequest req) {return req.toString();}
}class PageRequest {private Integer pageIndex;private Integer pageSize;public Integer getPageIndex() {return pageIndex;}public void setPageIndex(Integer pageIndex) {this.pageIndex = pageIndex;}public Integer getPageSize() {return pageSize;}public void setPageSize(Integer pageSize) {this.pageSize = pageSize;}
}

注册controller

import io.jooby.json.GsonModule;
import top.meethigher.mvc.controller.Controller;import static io.jooby.Jooby.runApp;public class MVCApplication {public static void main(String[] args) {runApp(args, app -> {// 设置 JSON 支持app.install(new GsonModule());//注册控制器app.mvc(new Controller());});}
}

jooby：做更多！ 更容易！
// 设置 JSON 支持
app.install(new GsonModule());
//注册控制器
app.mvc(new Controller());
});
}
}
