Scala project MySQL connection errors

Scala project MySQL connection errors - mysql

I'm trying to make my scala project connect to a mysql database (which I've spun up with MAMP) and keep getting this error. Any chance someone could help diagnose it? Thanks in advance!
This is my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="healthcenters">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>healthcenterdataload.DataToStoreClass</class>
<class>healthcenterdataload.HealthCenterData</class>
<properties>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/healthcenters"/>
<property name="hibernate.connection.username" value="root"/>
<property name="hibernate.connection.password" value="root"/>
</properties>
</persistence-unit>
</persistence>
Here's the bit where the storing is attempting to occur:
val con = DriverManager.getConnection("jdbc:mysql://localhost:3306/healthcenters?profileSQL=true")
em.persist(dataToStore)
con.commit()
con.close()
And here's the giant error output:
scala> import healthcenterdataload._
import healthcenterdataload._
scala> val url = "https://data.cityofnewyork.us/resource/8nqg-ia7v.json"
url: String = https://data.cityofnewyork.us/resource/8nqg-ia7v.json
scala> DataToStore.storeData(url)

Communication link failure error in spring boot

I have been trying to connect a database to my spring boot application but it didn't work out and give me an error. So, if anyone could give me a hint about what should I do?
I have tried to remove and add dependencies in pom.XML but nothing solved the issue
Backstory: I am trying to do a college project that is a web-service for an online store platform but this is my only error if the database connection succeeded I think there will be no other errors. I see an answer for another question have the same problem but non of the answers solved my problem

and that is my connection properties
spring:
datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3360/onlinemarket
username: root
password:
jpa:
hibernate.ddl-auto: update
generate-ddl: true
show-sql: true

Check whether you have proper dependencies in pom.xml like spring data jpa and mysql connector.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
Your application.yml should looks like below. You have to add hibernate dialect.
datasource:
url: jdbc:mysql://127.0.0.1:3360/onlinemarket
driver-class-name: com.mysql.jdbc.Driver
username: root
password:
jpa:
properties:
hibernate:
dialect: org.hibernate.dialect.MySQL57Dialect
ddl-auto: update
format_sql: true
show_sql: true

How to avoid exception when connecting spring boot application to My SQL database?

I am trying to connect my fleetapp to MySQL database.i have attached
the required dependencies while creating the project.Please see below
my stack trace to help me resolve the issues i am facing.
Well I have mention database related configuration in properties file.but still i am facing the issues.The username and password is also correct.

Can anyone help me on this issues?

Please run below query in MySQL workbench and then try.
INSERT INTO mysql.user (Host, User, Password) VALUES ('%', 'root', password('YOURPASSWORD'));
GRANT ALL ON *.* TO 'root'#'%' WITH GRANT OPTION;
Hope this will work.

if your username and pass are correct so look for an extra white space at the end of them, then delete it.

TomEE JPA MySql Configuration "An invalid Lifecycle transition was attempted"

I'm new to Java EE, spending some times in learning it.
Several hours on this error, cannot find exact similar questions, exept one student on udemy Q&A in same udemy course, but teacher cannot help the student.
The tutorial is teaching persistence using TomEE and JPA on MySQL.
I'm using Eclipse:
Eclipse Java EE IDE for Web Developers.
Version: 2018-09 (4.9.0)
TomEE Version:
Tomcat v9.0 Server
TomEE using JRE:
jdk-12.0.1
Project Java Build Path --> Module Path --> Execution Environment:
JavaSE-10 (jdk-12.0.1)
Java Compiler:
Use compliance from execution environment JavaSE-10
Actual MySql Connector in lib TomEE folder (tried several):
mysql-connector-java-8.0.17.jar
This is my tomee.xml
<tomee>
<Resource id="connessioneCorsoWeb" type="DataSource">
JdbcDriver com.mysql.jdbc.Driver
JdbcUrl jdbc:Mysql://127.0.0.1:3306/corso_java_web?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
UserName root
Password admin
</Resource>
</tomee>
this is the persistence.xml
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="1.0">
<persistence-unit name="corsoWebPersistence">
<jta-data-source>connessioneCorsoWeb</jta-data-source>
<properties>
<property name="openejb.jpa.auto-scan" value="true"/>
</properties>
</persistence-unit>
</persistence>
The console message on starting application does not help me

What can I look at to go deeper?
EDIT:
Removing persistence.xml the server starts.
Adding persistence.xml with only lines:
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="1.0">
</persistence>
the server starts.
Just right modifying persistence.xml as this:
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="1.0">
<persistence-unit>
</persistence-unit>
</persistence>
the server fails.
This is a more exhaustive extract from the current console:

Any single idea would be very appreciated.

Try this instead:
<?xml version="1.0" encoding="UTF-8"?>
<persistence
xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
version="2.1">

<properties>
<property
name="openejb.jpa.auto-scan"
value="true" />
</properties>
</persistence-unit>
</persistence>

Finally I solved, to be very clear:
in Udemy course was used
Tomcat v8.0 Server (apache-tomee-7.0.4)
instead I was using
Tomcat v9.0 Server (apache-tomee-8.0.0-M3-plume)
Now with old version is not necessary, but with tomee-8.0.0 it is necessary to set JPA in Project Facets (when checking JPA screen alert to configure it), or in JPA project properties.
I've tested both tomee versions, now both working.
This is a screen of my JPA config in my Tomcat v9.0 Server (apache-tomee-8.0.0-M3-plume)

"Unknown error" and "Failed to create JDBC connection" errors while creating new JDBC in wildfly

Below "Unknown error" occurs If I try to create a new JDBC (datasource) using wildfly-10.1.0.Final Web Management interface.
> **Unknown error**
>
> Unexpected HTTP response: 500
>
> Request {

Then I tried to do it manually by editing standalone.xml file as
<datasource jndi-name="java:jboss/datasources/PostgreSQLDS"
pool-name="PostgreSQLDS" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://localhost:5432/School</connection-url>

...
<driver name="mysql" module="com.mysql.driver">

...
By adding it manually, Now a WildFly Web Management Console shows newly created postgress data source. But by clicking Test Connection button in WildFLy Web Management Console, it popups below error message:

I had copied postgress jdbc driver postgresql-9.4.1210.jre7.jar file to:
C:\wildfly-10.1.0.Final\wildfly-10.1.0.Final\modules\system\layers\base\org\postgresql\main

my postgrsql database name is School and connection limit is set as -1
after being unsuccessful using postgres I also tried mysql but I got exactly same error messages given above while creating mysql datasource from wilefly web interface as well as by manually editing standalone.xml.
mysql driver "mysql-connector-java-5.1.39-bin.jar" is located at
C:\wildfly-10.1.0.Final\wildfly-10.1.0.Final\modules\system\layers\base\com\mysql\driver\main
