Spring AppContext Beans (Xml y Anotaciones)

Spring AppContext Beans (Xml y Anotaciones)

  Prototipo básico de Spring por AppContext beans Core por xml

https://github.com/jalbertomr/jalbertomr-springAppContextBeans/commit/167618cb7557c6970c3e86127ebe095e73ff1937


Se modifica la configuración de xml a Anotaciones.
   Se crea una clase con nombre AppConfig, que puede tener otro nombre ya que se referencia en la class main por
ApplicationContext appContext = new AnnotationConfigApplicationContext(AppConfig.class);

Se anota la Clase AppConfig con @Configuration

@Configuration
public class AppConfig {

    @Bean
    public ClaseParaBean cpb() {
        return new ClaseParaBean();
    }
   
    @Bean
    public Tierra tierra() {
        return new Tierra();
    }
   
    @Bean(name = "beanMarte")
    public Marte marte() {
        return new Marte();
    }
}

En la Clase Main

public static void main(String[] args) {
        System.out.println("Iniciado...");
       
       
        /* Metodo Beans */
        ApplicationContext appContext = 
        new AnnotationConfigApplicationContext(AppConfig.class);
        //ClaseParaBean cpb = (ClaseParaBean) appContext.getBean("claseBean");
        ClaseParaBean cpb = (ClaseParaBean)    appContext.getBean(ClaseParaBean.class);
        System.out.println("ClaseParaBean.getPropiedadDeClaseMensaje:" + cpb.getPropiedadDeClaseMensaje());
       
        Tierra tierra = (Tierra) appContext.getBean(Tierra.class);
        System.out.println("Tierra color:" + tierra.getColor() );
        System.out.println("Tierra diametro:" + tierra.getDiametro().toString());
       
        Marte marte = (Marte) appContext.getBean("beanMarte");
        System.out.println("Marte color:" + marte.getColor());
        System.out.println("Marte diametro:" + marte.getDiametro().toString());
       
        ((ConfigurableApplicationContext)appContext).close();
    }

  Se modifica la AppConfig por anotaciones para tener otra AppConfig2, y se modifica la clase main en la parte de AnnotationConfigApplicationContext(..)

AnnotationConfigApplicationContext appContext = new AnnotationConfigApplicationContext();
        appContext.register(AppConfig.class);
        appContext.register(AppConfig2.class);
        appContext.refresh();

La clase Tierra inicializa sus valores con la anotacion @Value en sus propiedades

public class Tierra {
    @Value("AZUL")
    private String Color;
    @Value("12742")
    private BigInteger diametro;

    public String getColor() {    return Color;     }
    public void setColor(String color) { Color = color;    }

    public BigInteger getDiametro() { return diametro; }
    public void setDiametro(BigInteger diametro) { this.diametro = diametro; }
}

Inyección por Constructor

   Creamos una clase Persona, y la declaramos en el beans.xml

Clase Persona
public class Persona {
    private int id;
    private String nombre;
    private String telefono;
   
    public Persona(int id, String nombre, String telefono) {
        this.id = id;
        this.nombre = nombre;
        this.telefono = telefono;
    }

    public Persona(int id) {
        this.id = id;
    }

    public Persona(String telefono) {
        this.telefono = telefono;
    }

En bean.xml declaramos el bean de Persona y las propiedades las inicializamos con constructor

beans.xml
...
<bean id="persona" class="com.bext.beans.Persona">
   <constructor-arg value="1"></constructor-arg>
   <constructor-arg value="Alberto"></constructor-arg>
   <constructor-arg value="4325235244"></constructor-arg>
</bean>
...

Al ejecutar la app tenemos
App.java
...
Persona per = (Persona) appContext.getBean("persona");
        System.out.println(per.getId() + " " + per.getNombre() +" "+per.getTelefono());
...

Iniciado...
1 Alberto 4325235244

Si solo inicializamos en el constructor con value="1" y ejecutamos la App tenemos

<bean id="persona" class="com.bext.beans.Persona">
   <constructor-arg value="1"></constructor-arg>
</bean>

Iniciado...
0 null 1

Observamos que con un solo valor en este caso "1" lo toma como String, o sea toma el constructor con un solo parametro de tipo String, pero este corresponde al Telefono. para que tome el int, hay que especificar el type="int" 

<bean id="persona" class="com.bext.beans.Persona">
   <constructor-arg type="int" value="1"></constructor-arg>
</bean>

Iniciado...
1 null null

Si especificamos el type="String" tomará el constructor con parámetro type String que corresponde al Telefono.

<bean id="persona" class="com.bext.beans.Persona">
   <constructor-arg type="String" value="1234567"></constructor-arg>
</bean>

Iniciado...
0 null 1234567

Podemos indicar la posición del parametro del constructor a inicializar

...
<bean id="persona" class="com.bext.beans.Persona">
   <constructor-arg index="2" value="1234567"></constructor-arg>
   <constructor-arg index="0" value="1"></constructor-arg>
   <constructor-arg index="1" value="Alberto"></constructor-arg>
</bean>
...

Inyección de Objectos

  A la Clase Persona le agregamos la Clase Pais.

Pais.java
public class Pais {
    private String nombre;

    public String getNombre() {
        return nombre;
    }

    public void setNombre(String nombre) {
        this.nombre = nombre;
    }
}

 
Persona.java
public class Persona {
    private int id;
    private String nombre;
    private String telefono;
    private Pais pais;
   
    public int getId() { return id; }
    public void setId(int id) {    this.id = id; }

    public String getNombre() {    return nombre;}
    public void setNombre(String nombre) { this.nombre = nombre;}

    public String getTelefono() { return telefono; }
    public void setTelefono(String telefono) { this.telefono = telefono; }

    public Pais getPais() {    return pais;}
    public void setPais(Pais pais) {this.pais = pais;}
}
App.java
public class App {

    public static void main(String[] args) {
        System.out.println("Iniciado...");
       
        /* Metodo Beans */
        ApplicationContext appContext = new ClassPathXmlApplicationContext("com/bext/xml/beans.xml");
        //AnnotationConfigApplicationContext appContext = new AnnotationConfigApplicationContext();
        //appContext.register(AppConfig.class);
        //appContext.register(AppConfig2.class);
        //appContext.refresh();
       
        Persona per = (Persona) appContext.getBean("persona");
        System.out.println(per.getId() + " " + per.getNombre() +" "+per.getTelefono() + " "+ per.getPais().getNombre());
       
        ((ConfigurableApplicationContext)appContext).close();
    }
}


beans.xml
...
<bean id="persona" class="com.bext.beans.Persona">
   <property name="pais" ref="pais"></property>
   <property name="id" value="1"></property>
   <property name="nombre" value="Alberto"></property>

Inyección de sub-Objeto

Ahora agregamos otra clase a la de Pais, será Ciudad.

Ciudad.java
public class Ciudad {
    private String nombre;

    public String getNombre() {    return nombre;}
    public void setNombre(String nombre) {this.nombre = nombre;}
}

Pais.java
public class Pais {
    private String nombre;
    private Ciudad ciudad;

    public String getNombre() {    return nombre;    }
    public void setNombre(String nombre) {    this.nombre = nombre;    }

    public Ciudad getCiudad() {    return ciudad;    }
    public void setCiudad(Ciudad ciudad) {    this.ciudad = ciudad;}
}

beans.xml
...
<bean id="persona" class="com.bext.beans.Persona">
   <property name="pais" ref="pais"></property>
   <property name="id" value="1"></property>
   <property name="nombre" value="Alberto"></property>
   <property name="telefono" value="1234567"></property>
</bean>

<bean id="pais" class="com.bext.beans.Pais">
    <property name="nombre" value="Mexico"></property>
    <property name="ciudad" ref="ciudad"></property>
</bean>

<bean id="ciudad" class="com.bext.beans.Ciudad">
    <property name="nombre" value="CDMX"></property>
</bean>
...

App.java
...
        Persona per = (Persona) appContext.getBean("persona");
        System.out.println(per.getId() + " " + per.getNombre() +" "+per.getTelefono() + " "+ per.getPais().getNombre() + " "+per.getPais().getCiudad().getNombre());...

Referenciando Beans (Alias)

Creamos un alias en beans.xml para Persona

<alias name="persona" alias="personaAlias"></alias>

Y se llama este alias desde App.java

Persona per = (Persona) appContext.getBean("personaAlias");

Tambien podemos poner el nombre de alias en la definición del bean de Persona con nombre="personaAlias2"

<bean id="persona" class="com.bext.beans.Persona" name="personaAlias2">
        <property name="pais" ref="pais"></property>
        <property name="id" value="1"></property>
        <property name="nombre" value="Alberto"></property>
        <property name="telefono" value="1234567"></property>
</bean>

Colecciones (Lista) Beans

  Vamos a definir valores para las ciudades del pais por medio de inicialización por xml.

beans.xml
...
    <bean id="persona" class="com.bext.beans.Persona" name="personaAlias2">
        <property name="pais" ref="pais"></property>
        <property name="id" value="1"></property>
        <property name="nombre" value="Alberto"></property>
        <property name="telefono" value="1234567"></property>
    </bean>

    <bean id="pais" class="com.bext.beans.Pais">
        <property name="nombre" value="Mexico"></property>
        <property name="ciudades">
            <list>
               <ref bean="ciudad1"></ref>
               <ref bean="ciudad2"></ref>
               <ref bean="ciudad3"></ref>
            </list>
        </property>
    </bean>

    <bean id="ciudad1" class="com.bext.beans.Ciudad">
        <property name="nombre" value="CDMX"></property>

    <bean id="ciudad3" class="com.bext.beans.Ciudad">
        <property name="nombre" value="Guadalajara"></property>
    </bean>

La App.java la modificamos para que podamos desplegar la lista
...
Persona per = (Persona) appContext.getBean("personaAlias2");
        System.out.println(per.getId() + " " + per.getNombre() +" "+per.getTelefono() + " "+ per.getPais().getNombre());

        for (Ciudad ciudad:  per.getPais().getCiudades()) {
            System.out.println(ciudad.getNombre());

AutoWire

   Modificamos a Pais para que no tenga la propiedad Ciudad, se traslada esta propiedad a Persona.

  En beans.xml borramos las propiedades que asignaban a Pais y Ciudad, estos valores se tomaran con autowire la cual las asociará por nombre. 

beans.xml
...
<bean id="persona" class="com.bext.beans.Persona" autowire="byName">
        <property name="id" value="1"></property>
        <property name="nombre" value="Alberto"></property>
        <property name="telefono" value="1234567"></property>
    </bean>

    <bean id="pais" class="com.bext.beans.Pais">
        <property name="nombre" value="Mexico"></property>
    </bean>

    <bean id="ciudad" class="com.bext.beans.Ciudad">
        <property name="nombre" value="CDMX"></property>
    </bean>
...

Persona.java

public class Persona {
    private int id;
    private String nombre;
    private String telefono;
    private Pais pais;
    private Ciudad ciudad;

   El autowire puede hacerse tambien por type "byType", así asignará las propiedades de personas comparadas por tipo, pero si hay dos o más tipos no  sabrá a que bean asignar la propiedad. Tambien esta autowire por constructor.

Scope (Singleton, Prototype)

Prototype genera instancias diferentes por bean

...
<bean id="persona" class="com.bext.beans.Persona" autowire="byName" scope="prototype">
        <property name="id" value="1"></property>
        <property name="nombre" value="Alberto"></property>
        <property name="telefono" value="1234567"></property>

Singleton genera una sola instancia por cada bean que se cree.

...<bean id="persona" class="com.bext.beans.Persona" autowire="byName" scope="singleton">
        <property name="id" value="1"></property>
        <property name="nombre" value="Alberto"></property>

Heroku Lab Run Non-web Java Dynos

El laboratorio esta hecho para corren con maven, en netbeans por default usa ant, aunque tiene algunos arquetipos de maven que se pueden usar. En este caso el arquetivo es diferente a los incluidos en netbeans, así que usaremos un projecto default de maven, para despues modificar el archivo de control maven pom.xml.

se usan dos archivos java
src/main/java/OneOffProcess.java

public class OneOffProcess
{
    public static void main(String[] args)
    {
        System.out.println("OneOffProcess executed.");
    }
} 

src/main/java/WorkerProcess.java

public class WorkerProcess
{
    public static void main(String[] args)
    {
        while(true) {
            try {
                Thread.sleep(1000);
            } catch(InterruptedException e) {}

            System.out.println("Worker process woke up");
        }
    }
}

$ docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

A More Practical Example
- run a Web application in a container
- the -P flag to map container ports to host ports
 Create a container usint the tomcat image, run in detached mode and map the tomcat ports to
the host ports.
docker run -d -P tomcat:7

SOAP Web Services con NetBeans

Antes de poner manos a la obra, conviene leer una pequeña y consisa introducción de NetBeans
sobre web services https://netbeans.org/kb/docs/websvc/intro-ws.html

Comenzando con JAX-WS Web Services, del learning trial https://netbeans.org/kb/docs/websvc/jax-ws.html. Aquí se elabora una aplicación que proporciona un Web Service de una simple calculadora utilizando la tecnología Java API for XML Web Services (JAX-WS). Tambien se muestran tres clientes que consumen el Web Service, uno en una plataforma Java SE como aplicación java. el segundo como una aplicación web con servlet, y el tercero como una aplicación web con JSP.

   Un detalle para el desarrollo de esta aplicación es que se tiene que habilitar al IDE y al Glassfish server para acceder al esquema externo para poder parsear el archivo WSDL (Web Service Description Language) del web service. algo que se describe en el documento, que en mi caso no me presento difucultades, pero sí actualize el Glassfish a la version 4.1.1, la que venia original con el IDE tenia bugs en su parte de adminstración web.

  En lo personal me agrada la facilidad de integrar los métodos del web service al cliente con solo arrastrarlo o por medio de Insertar Código..., es simplemente genial. Por el momento hacer esto de web services en el ide de Eclipse se ha visto más complicado, en cambio con netbeans es como un pan sin gluten.

  El Web Service puede ser deployado en un web container o en un EJB container. Si se Tiene un Apache Web server que solo tiene un web container, se deberá crear una aplicación web, no un EJB module.

El código en github
https://github.com/jalbertomr/startingJAX-WSWebServices.git

La estructura del conjunto de los projectos CalcularorWS y sus clientes es

Para Probar el web service creado en Netbeans click derecho en View Project -> NodoDelProjecto->WebService->CalculatorWS->Test Web Service

La corrida de la aplicación java que expota el web service nos da en la ventana output

run:

Hello Perrito!
add(3,4) Result = 7
substract(3,4) Result = -1
BUILD SUCCESSFUL (total time: 2 seconds)

La aplicación web en su modalidad servlet muestra en browser (notece se agrega al url /ClientServlet)

La aplicación web en su modalidad JSP muestra en browser

el projecto CalculatorWSAppMavenEJBModule es la versión en la modalidad de EJB Module que necesita glassfish. Los clientes tambien pueden hacer referencia a este web service con minimos cambios, solamente hay que refrescar el web service client del projecto. esto es borrar el web service y volverlo a asignar tomando como fuente el del EJB module.
