小编Ste*_*NYC的帖子

我已经在dw邮件列表上发布了这个问题,但没有得到答案.

我可以假设下面的YML格式不再适用于DW 0.7.0吗？(使用@ char插入env var)

server:
  applicationConnectors:
    - type: http
      bindHost: @OPENSHIFT_DIY_IP@
      port: @OPENSHIFT_DIY_PORT@

错误:

格式错误的YAML在第28行,第17列; 扫描下一个标记时; 找到无法启动任何令牌的字符@'@'.(不要使用@代替缩进); 在'reader',第28行,第17列:bindHost:@ OPENSHIFT_DIY_IP @

所以我决定使用这种格式:

server:
  type: simple
  applicationContextPath: /
  adminContextPath: /admin
  connector:
      type: http
      bindHost: localhost
      port: 8080

并尝试通过jvm选项覆盖它:

java -Ddw.server.connector.bindHost=$OPENSHIFT_DIY_IP -Ddw.server.connector.port=$OPENSHIFT_DIY_PORT -jar target/myapp.jar server myapp.yml

我的本地env变量:

OPENSHIFT_DIY_IP=localhost
OPENSHIFT_DIY_PORT=8080

我从这个设置得到的错误:

线程"main"中的异常java.lang.RuntimeException:java.net.SocketException:org.eclipse.jetty.setuid.SetUIDListener.lifeCycleStarting(SetUIDListener.java:213)中未解析的地址...引起:java.net.SocketException :sun.nio.ch.Net.translateToSocketException(Net.java:157)中未解析的地址...

我究竟做错了什么？

我试图从wget的结果中提取一条线但是遇到了麻烦.这是我的wget电话:

$ wget -SO- -T 1 -t 1 http://myurl.com:15000/myhtml.html

输出:

           => `-'

如果我这样做:

$ wget -SO- -T 1 -t 1 http://myurl.com:15000/myhtml.html …

我试图用guice/dropwizard配置hibernatebundle并需要帮助.我使用hubspot/dropwizard-guice/0.7.0第三方库以及dropwizard lib.

下面的代码显然不会工作,需要帮​​助才能搞清楚.我如何重写这个,以便hibernatebundle和最终的会话工厂自动注入任何需要它的bean.

MyApplication.java

public class MyApplication extends Application<MyAppConfiguration> {

    private final HibernateBundle<MyAppConfiguration> hibernateBundle = new HibernateBundle<MyAppConfiguration>(MyModel.class) {
        @Override
        public DataSourceFactory getDataSourceFactory(MyAppConfiguration configuration) {
            return configuration.getDataSourceFactory();
        }
    };

    @Override
    public void initialize(Bootstrap<MyAppConfiguration> bootstrap) {
        bootstrap.addBundle(hibernateBundle);  // ???

        bootstrap.addBundle(
            GuiceBundle.<MyAppConfiguration>newBuilder()
                    .addModule(new MyAppModule())
                    .enableAutoConfig(getClass().getPackage().getName())
                    .setConfigClass(MyAppConfiguration.class)
                    .build()
        );
    }

}   

MyAppModule.java

public class MyAppModule extends AbstractModule {

    @Provides
    public SessionFactory provideSessionFactory(MyAppConfiguration configuration) {
            // really wrong as it creates new instance everytime.
        return configuration.getHibernateBundle().getSessionFactory(); // ???
    }

}

MyAppConfiguration.java

public class …

我有这个VO

public class myVO {
    private final String latitude;
    private final String longtitude;
    private final String meterRadius;

    public myVO(String latitude, String longtitude, String meterRadius) {
        this.latitude = latitude;
        this.longtitude = longtitude;
        this.meterRadius = meterRadius;
    }

    public String getLatitude() {
        return latitude;
    }

    public String getLongtitude() {
        return longtitude;
    }

    public String getMeterRadius() {
        return meterRadius;
    }

}

和休息服务

@Path("/listrs")
@Produces(MediaType.APPLICATION_JSON)
public class MyResource {
    Logger logger = LoggerFactory.getLogger(MyResource.class);

    private final AtomicLong counter;

    public MyResource(String template, String defaultName) {
        //this.template = …
