Configuracion Debuger by Artur C.

Editar pom.xml y meter la configuracion del debuger:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005</jvmArguments>
    </configuration>
</plugin>

Ir al menu Run -> Edit Configurations -> Boton + -> Remote
Le damos un nombre mejor que el de "unnamed" y click en Apply

Configuracion del archivo application.properties

Ejemplo configuracion JPA:

spring.datasource.url=jdbc:mysql://localhost:3306/demo_v3?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=secret1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.show-sql=true

#spring.jpa.hibernate.ddl-auto=none
spring.jpa.hibernate.ddl-auto=update
#spring.jpa.hibernate.ddl-auto=create
#spring.jpa.hibernate.ddl-auto=create-drop

#logging.level.root=TRACE
logging.level.org.springframework.transaction=TRACE
logging.level.org.hibernate.SQL=TRACE

Configuracion hibernate.cfg.xml

<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name = "hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name = "hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <!-- Assume test is the database name -->
        <property name = "hibernate.connection.url">jdbc:mysql://localhost:3306/demo-hibernate?serverTimezone=UTC</property>
        <property name = "hibernate.connection.username">root</property>
        <property name = "hibernate.connection.password">secret1234</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <property name="hibernate.show_sql">true</property>
        <!-- List of XML mapping files -->
        <!-- <mapping resource = "Employee.hbm.xml"/> -->
    </session-factory>
</hibernate-configuration>

Nota sobre la validacion de esquemas de las BD

create - creates the schema, destroying previous data
update - update existing schema
validate - validate the schema, makes no changes to the database
create-drop - create the schema with destroying the data previously present(if there). It also drop the database schema when the SessionFactory is closed.

Estructura para una aplicacion Spring Web

Dentro del package folder (por ejemplo /booking-pom-hotel/src/main/java/com/pomhotel/booking):

mkdir application; 
mkdir application/domain;
mkdir application/domain/entities;
mkdir application/domain/factories;
mkdir application/models;
mkdir application/repositories;
mkdir application/services;
mkdir ui;
mkdir ui/controllers;

Dentro del resources folder:

mkdir static;
mkdir static/css;
mkdir static/js;
mkdir templates;
mkdir templates/error;
touch templates/index.html;
mkdir templates/fragments;

El arbol de directorios de la applicacion queda de la siguiente manera:
