Información de microserver springboot_lab, hostname: 127.0.1.1 propiedad de clase 'asignadaExternamente' en application.properties tiene el valor: asignada en application.properties
https://github.com/jalbertomr/springboot_lab/commit/ff7844365eb01a6190ee23fbdc521ae8269f0c84
El microservicio con SprinbBoot que se creo desde linea de comandos CLI, nos dejo una estructura de proyecto, sobre la cual es importada como proyecto existente en Maven desde Eclipse.
Este Eclipse (photon) se el agregan desde marketplace JBoss tools, Git, y m2Eclipse desde help->install new software... (
http://download.eclipse.org/technology/m2e/releases), tambien el Spring Tool Suite STS.Con el m2Eclipse podemos integrar comandos maven al Ide.
Al proyecto le agregaremos un controlador REST con ruta /api/info para que nos de simple información de nuestro microservicio como el host.
Esto con las anotaciones en la clase controller
@RestConroller
@RequestMapping("/ruta")
y en el método de la clase
@RequestMapping(method=RequestMethod.GET, value="/info", produ...)
Configuración Externa
Los atributos de la clase se pueden asignar desde fuera del programa en este caso en el archivo de recursos application.properties, con la anotación en la clase@ConfigurationProperties(prefix="asignaciones")
src/main/resources/application.properties
asignaciones.asignadaExternamente=asignada en application.properties
Al ejecutarlo vemos
Al agregar la dependencia al proyecto podemos obtener una serie de informacion sobre la aplicación.
