I have a spring boot 2 application with AWS MySQL.
MySQL has been created in AWS RDS and the inbound rule is set to "All Traffic" for testing.
Able to connect to mysql from my local machine mysqlworkbench. But, getting error if I connect from my Spring boot based application from my local.
Public Accessibility is also set to Yes. Not sure what config is missing?

Versions
Java version - 14
Spring boot version - 2.3.3
mysql-connector-java - 8.0.21
MySQL DB engine version in AWS RDS - 8.0.20
Local MySQL Workbench to AWS MySQL - Working
nc -vz <RDS_MYSQL_HOSTNAME> 3306 - Working
My Springboot application with local MySQL - Working
AWS RDS MySQL instance - db.t2.micro
There is one possibility that might be causing this and I had a somewhat similar issue.
Related to JVM DNS Cache TTL. The problem occurs because the default is to cache a DNS forever and because AWS resources IP Address changes and so it shouldn't be set to cache forever.
Refer java-dg-jvm-ttl
globally, for all applications that use the JVM. Set networkaddress.cache.ttl in the $JAVA_HOME/jre/lib/security/java.security file:
networkaddress.cache.ttl=60
for your application only, set networkaddress.cache.ttl in your application’s initialization code:
java.security.Security.setProperty("networkaddress.cache.ttl" , "60");

Hello I have problem to connecting SpringBoot within Docker Container to localhost MySQL
this is my url on eclipse (application.properties) to connect:
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://docker.for.win.localhost:3306/project_8?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
my Dockerfile:
FROM openjdk:12-jdk-alpine
ARG JAR_FILE
COPY ./build/libs/web-1.0-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
So, I create docker image good:
docker build -t web .
than, when I try to run that image it's failling:
docker run -p 8080:8080 web
Here is error report:
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
Things I've checked and they certainly work well:
-You can connect to MySQL instance from laptop. Its not MySQL problem configuration.
-When I'm running springboot locallly on machine it is working fine so it's something with docker problem.
-I tryed to restart MySQL (services.msc)
whole error report:

The application.yml of my springboot project:
server:
port: 8080
spring:
jpa:
show-sql: true
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://mysql:3306/user?characterEncoding=utf-8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
username: user
password: pwd
In addition, I can access mysql container by changing the url of datasource to "jdbc:mysql://ip:3306/user..."
Thank you very much for taking the time to review and answer
mysql URL formate is :--
jdbc:mysql://<HOST>:<PORT>/<DATABASE>
in your case hostname is mysql that is wrong. Please provide correct hostname n check once.
Finally, I solve the problem through the following process.
If you turn on the firewall, you need to do the following steps：
view firewall NAT forwarding
firewall-cmd --query-masquerade
If result:no,then:
firewall-cmd --zone=public --add-masquerade --permanent
firewall-cmd --reload
turn on IPv4 forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward
sysctl -p
If you just want to access through the container name, that's it,but
if you still want to access through the host IP address,you should:
get container-docker interface name:
[admin#localhost ~]# ifconfig

allow network packets to host from your docker bridge network
firewall-cmd --permanent --zone=trusted --change-interface=br-4cf89773q8e0

I'll post my configs and stacktrace below. And also, when I remove UserRepository it works fine..

And even when I declare a Hibernate Dialect, still gives same stacktrace. What have I tried?
Tried to network them, tried links-to..
Has anyone else had same problem?
It turned out that I needed to comment out the default Spring Boot Test case, since it was failing a stupid test. Now it works.
For the future reference, links are deprecated in docker, as I found out today, they were replaced by user-networks, but since Docker creates a default network for your containers, I didn't need to do any networking.
I'm creating a spring boot project. Then i try to connect mysql database to that project. I got the error called "HikariPool-1 - Exception during pool initialization".
This is the whole stacktrace.

One way is specify the server time zone in the jdbc connection url as:
jdbc:mysql://xxxxx:3306?serverTimezone=UTC
(You can use other timezones too)
Another way is to set the timezone property in the mysql server. Follow the documentation here
If you are deploying your mysql in azure:
set the server parameter time_zone to particular zone.
Follow the doc here
So I'm trying to connect mysql database to JHipster, but it's throwing "unknown database" error:

2019-07-24 09:43:11.716 WARN 86962 --- [ restartedMain] o.h.e.j.e.i.JdbcEnvironmentInitiator : HHH000342: Could not obtain connection to query metadata : Unknown database 'test'
Do I have to configure something in application.yml in order to connect the database server? My pom.xml has mysql-connector dependency, so I don't think that's causing the issue. Also, I have started mysql server prior to launching the application.
Any help is appreciated.
You need to configure the credentials at
src/main/resources/config/application-dev.yml
or
src/main/resources/config/application-prod.yml
Depending on which profile you are using
check this properties: (this is an example and yours might be different depending on the driver)
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:h2:mem:jhipstersampleapplication;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
username: jhipsterSampleApplication
password:
if everything is fine then it should connect without problem.
If you still have problems connecting be sure you can access the schema with the given address, user and password.
