airlift 简单试用

airlift 使用简单,而且周边集成也不少,只是官方文档比较少,使用最多的也是trino 以及presto 中,trino 代码基于airlift 框架的开发代码看起来是
很简洁的

代码简单说明

  • app 部分
    主要是要一个rest api ,包装了静态页面以及应用的启动入口(airlift 自带的bootstrap 能力)
    App.java
 
public class App {
    public static void main(String[] args) {
        Bootstrap app = new Bootstrap(ImmutableList.<Module>builder()
                .add(new NodeModule())
                .add(new Module() {
                    @Override
                    public void configure(Binder binder) {
                       // node 环境配置,还是比较重要的
                        configBinder(binder).bindConfigDefaults(NodeConfig.class, nodeConfig -> {
                           nodeConfig.setEnvironment("test");
                        });
                        // rest api 注册
                        jaxrsBinder(binder).bind(MyDemoResource.class);
                        // 静态页面配置
                        httpServerBinder(binder).bindResource("/","webapp").withWelcomeFile("index.html");
                        httpServerBinder(binder).bindResource("/dalongdemoapp","webapp").withWelcomeFile("index.html");
                    }
                })
                .add(new HttpServerModule())
                .add(new JsonModule())
                .add(new JaxrsModule())
                .add(new EventModule())
                .build());
        app.initialize();
    }
}

MyDemoResource.java

@Path("/")
public class MyDemoResource
{
    private static final Logger log = Logger.get(MyDemoResource.class);
 
    @GET
    @Path("/v1/info")
    @Produces(APPLICATION_JSON)
    public String getInfo(
            @Context HttpServletRequest servletRequest) {
       return  "dalongdemo";
    }
} 
  • package 部分
    实际上参考了trino 的打包
    package/src/main/provisio/myapp.xml
 
<runtime>
    <!-- Target -->
    <archive name="${project.artifactId}-${project.version}.tar.gz" hardLinkIncludes="**/*.jar" />
 
    <!-- Server -->
    <artifactSet to="lib">
        <artifact id="${project.groupId}:app:${project.version}" />
    </artifactSet>
 
</runtime>

说明

airlift 实际上就是对于不少现有框架的包装,使用起来还是很方便的,值得试试,上边app pom 文件就没贴,需要的可以github 查看
