Dorado
======
简单、快速、轻量级的http restful server实现，基于Netty4和JDK1.8+
Features
--------

- 内置JSON/Protobuf序列化支持，JSON序列化框架使用Fastjson, 依赖内置；\
如果使用protobuf序列化，需要自行添加protobuf依赖, protobuf版本2.x
- 基于Trie数据结构实现的Http路由支持
路由path支持任意的java正则表达式，通过{pathVariable:regex}这种方式支持路径变量
- 支持文件上传
- Spring框架支持，默认支持注解方式初始化spring容器
- SpringBoot集成
- 集成swagger restful API文档生成工具
- 过滤器支持，实现类似于spring mvc的interceptor功能
- 支持全局异常处理
- 支持统一响应格式处理
## Latest version
**0.0.56**
Maven

```xml

```
Quick start
-----------
- 最简单的Dorado rest server
```java
public class Application {
public static void main(String[] args) throws Exception {
// create simple rest server, scanPackages现在可选，如果不设置
//系统默认会自动找到main主类所在的包作为basePackage进行扫描
DoradoServerBuilder.forPort(18888).build().start();
}
}
```
- 更多定制化参数服务器
```java
public class Application {
public static void main(String[] args) throws Exception {
DoradoServerBuilder.forPort(18888).acceptors(2).ioWorkers(4)
.minWorkers(10).maxWorkers(100)
.backlog(1024)
.maxConnection(500).maxPendingRequest(10000)
.maxIdleTime(120).sendBuffer(256 * 1024)
.recvBuffer(256 * 1024)
.scanPackages("com.rtbstack.demo.controller",
"com.rtbstack.demo.controller1")
.build().start();
}
}
```
- spring框架支持
DoradoServerBuilder.forPort(port).**springOn()**
由于框架本身不直接依赖spring框架，如果启用spring之后，务必自行添加spring框架相关依赖到项目中，否则系统启动会出现ClassNotFoundException
```java
public class Application {
public static void main(String[] args) throws Exception {
DoradoServerBuilder.forPort(18888).springOn()
.scanPackages("com.rtbstack.demo",
"com.rtbstack.demo.controller1")
.build().start();
}
}
```
- Rest Controller
```java
@Controller
@Path("/campaign")
public class CampaignController {
@Path("/{id:[0-9]+}")
@GET
public Campaign newCampaign(int id) {
Campaign campaign = new Campaign();
campaign.setId(id);
campaign.setName("test campaign");
return campaign;
}
@Path("/name")
public String campaignName() {
return String.format("hello_campaign", "");
}
@POST
public Campaign save(Campaign campaign) {
System.out.println(campaign);
return campaign;
}
@Path("/{id}")
@DELETE
public void deleteCampaign(int id) {
System.out.println("delete campaign, id: " + id);
}
@GET
@Path("/{id}")
public Campaign getCampaign(int id) {
return Campaign.builder().withId(12)
.withName("网易考拉推广计划")
.build();
}
}
```
- Filter
```java
@FilterPath(include = "/campaign/*")
public class DemoFilter implements Filter {
@Override
public boolean preFilter(HttpRequest request, HttpResponse response) {
System.out.println("execute demo filter");
response.sendError(403, "Forbidden");
return false;
}
}
```
- 文件上传支持
支持文件上传很简单，只需要将controller方法的参数设置未MultipartFile或者MultipartFile[]即可，单文件用MultipartFile,
多文件用MultipartFile[]
```java
@Path("/file/upload")
@POST
public String uploadFile(MultipartFile[] fs,String name) {
for(MultipartFile f:fs) {
System.out.println(f.getName());
System.out.println(f.getContentType());
System.out.println(f.getSize());
}
return String.format("name: %s, file info: %s", name,f.toString());
}
```
- 全局异常处理
dorado支持用户通过自定义的类来进行全局异常处理，处理异常的方法名必须是handleException，类上面增加ExceptionAdvice注解
```java
@ExceptionAdvice
public class TestExceptionAdvice {
@ExceptionType(MyException.class)
@Status(400) //Status注解来指定http响应状态码
public String handleException(MyException ex) {
return "cause: " + ex.getClass().getName() + "," + ex.getMessage();
}
@ExceptionType(Exception.class)
public String handleException(Exception ex) {
return "use default exception handler,cause: " + ex.getClass().getName() + "," + ex.getMessage();
}
}
```
- 全局统一响应格式处理
在实际项目开发中，基于rest的服务一般都会定义统一的响应格式，如下面所示格式：
```json
{
"code": 0,
"data": data,
"msg": "OK"
}
```
为了避免在每个方法的时候都要执行相同的处理操作，dorado支持定义一个io.github.javagossip.dorado.rest.http.MethodReturnValueHandler来
实现这个功能
```java
public class TestMethodReturnValueHandler implements MethodReturnValueHandler {
@Override
public Object handleMethodReturnValue(Object value, MethodDescriptor methodDescriptor) {
return TestResp.builder().withCode(0).withMsg("OK").withData(value).build();
}
//自定义这个方法实现，用来控制哪些返回值需要被这个类进行处理
public boolean supportsReturnType(MethodDescriptor returnType) {
return true;
}
}
```

注解说明
--------
### 类注解
| 注解类型 | 描述 |
|:-------------: |:---------------:|
| Controller | 控制器 |
| Path | 控制器访问Path|
| FilterPath |过滤器过滤路径,包括include以及exclude属性|
### 方法注解
| 注解类型 | 描述 |
|:-------------: |:---------------:|
| Path | 资源访问路径，实际访问path为：controllerPath+methodPath |
|GET|方法仅支持Http GET请求|
|POST|方法仅支持Http POST请求|
|PUT|方法仅支持HTTP PUT请求|
|DELETE|方法仅支持HTTP DELETE请求|
|Consume | 方法参数支持的MediaType, 如：application/json|

内置服务
--------
- Get Server configuration: **[http://{ip}:{port}/config]()**
- Get Server status: **[http://{ip}:{port}/status]()**
- List All services: **[http://{ip}:{port}/services]()**
SpringBoot集成
--------------
- 添加dorado-spring-boot-starter核心依赖
```xml
io.github.javagossip
dorado-spring-boot-starter
${dorado.version}
```
- 基于springboot的dorado应用
```java
@SpringBootApplication
@EnableDorado //用这个注解开启dorado server
public class SpringBootApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootApplication.class, args);
}
}
```
或者直接使用DoradoSpringBootApplication来替换SpringBootApplication和EnableDorado,如下：
```java
@DoradoSpringBootApplication
public class SpringBootApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootApplication.class, args);
}
}
```
- Dorado框架的spring-boot配置参数
|参数名|描述|默认值|
|:-----------|:----------:|:-----------:|
|dorado.port|dorado server监听端口|18888|
|dorado.backlog|backlog队列大小|10000|
|dorado.acceptors|dorado acceptor count|cpu核心数*2|

|dorado.max-packet-length|http请求包体大小|1M|
swagger集成
-----------
如果对swagger还不了解的话，参考：[https://swagger.io/]()
- 添加dorado-swagger-ui依赖
```xml
io.github.javagossip
dorado-swagger-ui
${dorado.version}
```
- 项目启动类中使用EnableSwagger注解启用swagger
```java
@EnableSwagger
public class Application {
public static void main(String[] args) throws Exception {
// create simple rest server
DoradoServerBuilder.forPort(18888).maxPacketLength(1024*1024*10)
.build().start();
}
}
```
- 设置Api文档全局信息\
实现**io.github.javagossip.dorado.swagger.ext.ApiContextBuilder**接口
```java
@Component //如果是集成spring或springboot环境的话，直接增加component注解即可
@Override
// 这里定制Api全局信息，如文档描述、license,contact等信息
public ApiContext buildApiContext() {
Info info = new Info()
.contact(new Contact().email("[email protected]").name("weiping wang")
.url("http://github.com/javagossip/dorado"))
.license(new License().name("apache v2.0").url("http://www.apache.org"))
.termsOfService("http://swagger.io/terms/").description("Dorado服务框架api接口文档")
.title("dorado demo api接口文档").version("1.0.0");
//构造api访问授权的apiKey
ApiKey apiKey = ApiKey.builder().withName("Authorization").withIn("header").build();
ApiContext apiContext = ApiContext.builder().withApiKey(apiKey)
.withInfo(info).build();
return apiContext;
}
```
非spring环境需要在resources/META-INF/services下的io.github.javagossip.dorado.swagger.ext.ApiContextBuilder文件中增加如下配置：
**io.github.javagossip.dorado.demo.ApiContextBuilderImpl**
- 在controller实现里面增加swagger相关的注解即可自动生成在线的api doc
```java
@Controller
@Path("/campaign")
@Api(tags = { "营销活动管理" })
public class CampaignController {
@Autowired
private CampaignService campaignService;
@Path("/{id:[0-9]+}")
@GET
@ApiOperation("新建campaign")
public Campaign newCampaign(@PathVariable("id") int id) {
Campaign campaign = new Campaign();
campaign.setId(id);
campaign.setName("test campaign");
return campaign;
}
}
```
* spring-boot环境，可以直接引入dorado-swagger-spring-boot-starter依赖来进一步简化swagger的使用
```xml
io.github.javagossip
dorado-swagger-spring-boot-starter
${dorado.version}
```
然后在application.properties配置文件中增加如下配置即可：
```java
dorado.swagger.title=Zhuque's dashboard api
dorado.swagger.description=${dorado.swagger.title}
dorado.swagger.license=Apache License
dorado.swagger.licenseUrl=http://www.apache.org/licenses/LICENSE-2.0
dorado.swagger.contact.name=weiping wang
[email protected]
dorado.swagger.contact.url=https://github.com/javagossip
//API全局认证配置
dorado.swagger.apiKey.name=Authorization
dorado.swagger.apiKey.in=header or query
```
- 浏览器访问如下地址即可
http://{host}:{port}/swagger-ui.html
