To generate a key with PuTTY, you should: Download and start the puttygen.exe generator. In the 'Parameters' section choose SSH2 DSA and press Generate. Move your mouse randomly in the small screen in order to generate the key pairs. Enter a key comment, which will identify the key (useful when. To create a new key pair, select the type of key to generate from the bottom of the screen (using SSH-2 RSA with 2048 bit key size is good for most people; another good well-known alternative is ECDSA). Then click Generate, and start moving the mouse within the Window. Putty uses mouse movements to. To create and use SSH keys on Windows, you need to download and install both PuTTY, the utility used to connect to remote servers through SSH, and PuTTYgen, a utility used to create SSH keys. On the PuTTY website, download the.msi file in the Package files section at the top of the page, under MSI (‘Windows Installer’). Next, install it on your local computer by double clicking it and using the. May 05, 2019 Creating SSH keys with PuTTYgen. To generate an SSH key pair on Windows using PuTTYgen perform the following steps: Start the PuTTYgen tool, by double-clicking on its.exe file or going to the Windows Start menu → PuTTY (64-bit) → PuTTYgen. For “Type of key to generate”. Putty type of key to generate. Puttygen aka Putty Key Generator. The key generation utility – PuTTYgen can create various public-key cryptosystems including Rivest–Shamir–Adleman (RSA), Digital Signature Algorithm (DSA), Elliptic Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital Signature Algorithm (EdDSA) keys.
Spring Boot MySQL tutorial shows how to use MySQL database in a Spring Bootapplication.
Spring is a popular Java application framework for creatingenterprise applications. Spring Boot is an evolution of Springframework which helps create stand-alone, production-grade Spring basedapplications with minimal effort.

How to generate primary keys with JPA and Hibernate. By Thorben Janssen 10 Comments. 4 options to generate primary keys. Earlier i was using custom table generator to generate primary key. I am using mysql database, i suppose it does not support sequence. Dec 02, 2017 This page will walk through Spring Boot CrudRepository example. Spring Boot Data enables JPA repository support by default. CrudRepository provides generic CRUD operation on a repository for a specific type.CrudRepository is a Spring data interface and to use it we need to create our interface by extending CrudRepository.Spring provides CrudRepository implementation class. OnlineTutorialsPoint - A Blog for learning Java and Frameworks like Hibernate and Spring. Developers guide to learn Java, Phyton, PHP, Java8, Spring Boot, Hibernate. Jan 24, 2017 Why should not use the AUTO JPA GenerationType with MySQL and Hibernate. To use a portable solution that manages to customize the SEQUENCE generator while still allowing you to pick the IDENTITY generator for MySQL. This whole discussion is only relevant if you are still using database-generated keys (being it via identity columns.
MySQL
MySQL is a leading open source database management system. It isa multi-user, multithreaded database management system. MySQL is especiallypopular on the web. It is one part of the very popular LAMP platform,which includes Linux, Apache, MySQL, and PHP. MySQL database is availableon most important OS platforms. It runs on BSD Unix, Linux, Windows, and Mac.
MySQL setup
We are going to show how to install MySQL database on a Debian Linux system.
This command installs MySQL server and related packages.
These two commands are used to start and stop MySQL.
We check the status of the database with
service mysql status
command.Now we need to reset the root password. We start the mysql command line tool.(The server must be running.) We connect as root.
Spring Boot Generate Random String Mysql Sub Keyboard
We set a new password for root.
We can use
mysql_secure_installation
to increase security of MySQLserver. We are given the choice to improve the MySQL root password, removeanonymous user accounts, disable root logins outside of localhost, and removetest databases.We create a new
testdb
database.We create a new MySQL user and grant it privileges to the
testdb
database.Creating MySQL table
Now we are going to create a new MySQL table called
cities
.cities_mysql.sql
This is SQL to create the
cities
table.With the
source
command, we execute the SQL statements.Spring Boot MySQL example
The following application is a simple Spring Boot web application, which usesMySQL database. We have a home page with a link to display data from a databasetable. We use Freemarker templating system to join data with HTML.
This is the project structure.
Spring Boot starters are a set of convenient dependency descriptors whichgreatly simplify Maven configuration. The
spring-boot-starter-parent
has some common configurations for aSpring Boot application. The spring-boot-starter-web
is a starterfor building web, including RESTful, applications using Spring MVC. Thespring-boot-starter-freemarker
is a starter for building MVC webapplications using Freemarker views. The spring-boot-starter-data-jpa
is a starter for using Spring Data JPA with Hibernate.The
mysql-connector-java
dependency is for the MySQL database driver.The
spring-boot-maven-plugin
provides Spring Boot support in Maven, allowing us to package executable JAR or WAR archives. Its spring-boot:run
goal runs the Spring Boot application.resources/application.properties
In the
application.properties
file we write various configurationsettings of a Spring Boot application. With the spring.main.banner-mode
property we turn off the Spring banner. With the logging.level.org.springframework
we set the logging level for spring framework to ERROR
.In the spring datasource properties we set up the MySQL datasource.This is the
City
entity. Each entity must have at least twoannotations defined: @Entity
and @Id
.The
@Entity
annotation specifies that the class is anentity and is mapped to a database table while the @Table
annotationspecifies the name of the database table to be used for mapping.The primary key of an entity is specified with the
@Id
annotation.The @GeneratedValue
gives a strategy for generating the values of primary keys.com/zetcode/repository/CityRepository.java
By extending from the Spring
CrudRepository
, we will havesome methods for our data repository implemented, including findAll()
.This way we save a lot of boilerplate code.ICityService
provides the findAll()
contractmethod declaration to get all cities from the data source.com/zetcode/service/CityService.java
CityService
contains the implementation of the findAll()
method. We use the repository to retrieve data from the database.CityRepository
is injected.The
findAll()
method of the repository returns the list ofcities.MyController
class is annotated with @Controller
.We inject an
ICityService
into the countryService
field.We map a request with the
/showCities
path to the controller'sfindCities()
method. The @GetMapping
annotation maps a GET request to the method. The model gains a list of cities and the processing issent to the showCities.ftlh
Freemarker template file.resources/templates/showCities.ftlh
In the
showCities.ftlh
template file, we display the data inan HTML table.In the
index.html
there is a link to show all cities.com/zetcode/Application.java
The
Application
sets up the Spring Boot application.The @SpringBootApplication
enables auto-configuration andcomponent scanning.Mysql Random Function
After the application is run, we can navigate to
localhost:8080

In this tutorial, we have showed how to use MySQL database ina Spring Boot application.
