Each Dropwizard application has its own subclass of the Configuration class which specifies environment-specific parameters. These parameters are specified in a YAML configuration file which is deserialized to an instance of your application’s configuration class and validated. The application we’ll be building is a high-performance Hello World service, and one of our requirements is that we need to be able to vary how it says hello from environment to environment. We’ll need to specify at least two things to begin with: a template for saying hello and a default name to use in case the user doesn’t specify their name.

Health checks give you a way of adding small tests to your application to allow you to verify that your application is functioning correctly in production. We strongly recommend that all of your applications have at least a minimal set of health checks. 其实这个是可有可无的,为了安全起见,这里先加上。(官方例子中要求加上o(╯□╰)o)
十一、再次修改第六步时创建的Application中的run方法。
public void run(HelloWorldConfiguration configuration, Environment environment) throws Exception {
//声明一个resource,并传入初始化的值,该值由configuration读取的yml配置文件中的值。
//可以启动多个resource
final HelloWorldResource resource = new HelloWorldResource(
configuration.getTemplate(),
configuration.getDefaultName()
);
//声明一个检查点,让其进行检查该模板的正确性。
final TemplateHealthCheck healthCheck =
new TemplateHealthCheck(configuration.getTemplate());
environment.healthChecks().register("template", healthCheck);
environment.jersey().register(resource);
}
Traits are a fundamental unit of code reuse in Scala. A trait encapsulates method and field definitions, which can then be reused by mixing them into classes. Unlike class inheritance, in which each c

说明:%DOMAIN_HOME%:指WebLogic Server 域(Domain)目录
例如我的做测试的域的根目录 DOMAIN_HOME=D:/Weblogic/Middleware/user_projects/domains/base_domain
