Bootique初探

介绍

Bootque改进了无容器应用启动的现有技术。它使你可以编写看起来像命令一样并由模块组成的Java应用。号称要比SpringBoot快10倍以上。今天我就来试一试它。Bootique.io是项目的官方站点。

HelloWorld [1]

  • 创建项目

    zzw:challenge zzw$mkdir boonique_fist_attempt
zzw:challenge zzw$cd boonique_first_attempt
zzw:boonique_fist_attempt zzw$mkdir -p src/main/java/com/wonderingwall/

  • 创建pom.xml

    zzw:boonique_fist_attempt zzw$ vi pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <artifactId>bootique-logback</artifactId>

            <plugin>
                <artifactId>maven-shade-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

  • 创建App.Java

    zzw:boonique_fist_attempt zzw$ vi src/main/java/com/wonderingwall/App.java
package com.wonderingwall;

import com.google.inject.Binder;
import com.google.inject.Module;
import io.bootique.Bootique;
import io.bootique.jersey.JerseyModule;

/**
 * Hello world!
 */
public class App implements Module {

    public static void main(String[] args) {
        Bootique.app(args)
                .autoLoadModules()
                .module(App.class)
                .exec()
                .exit();
    }

    @Override
    public void configure(Binder binder) {
        JerseyModule.extend(binder).addResource(HelloApi.class);
    }
}

  • 创建RestApi接口类HelloApi.java 。这里符合Java JAX-RS API标准

    zzw:boonique_fist_attempt zzw$ vi src/main/java/com/wonderingwall/HelloApi.java
package com.wonderingwall;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/")
public class HelloApi {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String get() {
        return "{\"message\":\"Hello, Bootique!!\"}";
    }

}

  • 看下未编译前的目录结构

    zzw:boonique_fist_attempt zzw$ tree .
.
├── pom.xml
└── src
    └── main
        └── java
            └── com
                └── wonderingwall
                    ├── App.java
                    └── HelloApi.java

5 directories, 4 files

  • 直接运行jar可以得到一份类似命令行帮助文档。

    zzw:boonique_fist_attempt zzw$ java -jar target/first-attempt-0.0.1-SNAPSHOT.jar
NAME
      first-attempt-0.0.1-SNAPSHOT.jar

OPTIONS
      -c yaml_location, --config=yaml_location
           Specifies YAML config location, which can be a file path or a URL.

      -h, --help
           Prints this message.

      -H, --help-config
           Prints information about application modules and their configuration options.

      -s, --server
           Starts Jetty server.

  • 上面帮助我们可以看到，我们只要加入--server就可以运行我们的程序了。

    zzw:boonique_fist_attempt zzw$ java -jar target/first-attempt-0.0.1-SNAPSHOT.jar -s

    浏览器中键入http://localhost:8080就可以获得我们所需的结果了。

  • 路径配置则是通过yaml文件配置。你可以查看帮助文件使用-H参数。我这里添加了config.yml

    zzw:boonique_fist_attempt zzw$ cat config.yml
jetty:
  context: /hello
  connectors:
    - port: 8088

  • 运行结果如下

        zzw:boonique_fist_attempt zzw$ java -jar target/first-attempt-0.0.1-SNAPSHOT.jar -s --config=config.yml

    浏览器中键入http://localhost:8088/hello

总结

总体的开发流程和SpringBoot差不多，运行的速度的确显而易见，毕竟Guice是Google开源的一个依赖注入类库，相比于Spring IoC来说更小更快。Bootique文档不多，但是入门够用，要一定的开发基础才能深入。关注度也不够高。不过的确很适合现在的微服务架构轻量级的开发，快速而高效。我这里直接Vim编写了，没有用到IDE，稍微有所了解还好，否则没有提示开发难度还是会上升，幸亏只是基于Maven管理。
