I am haveing problem using MySql with Grails 3 project.
My Application.yml
dataSource:
pooled: true
jmxExport: true
driverClassName: com.mysql.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
username: root
password: *****
environments:
development:
dataSource:
dbCreate: create-drop
url: jdbc:mysql://localhost:3306/mydb
also tried
environments:
development:
dataSource:
dbCreate: create-drop
url: jdbc:mysql://localhost/mydb
My Build.gradle
dependencies {
compile "org.springframework.boot:spring-boot-starter-logging"
compile "org.springframework.boot:spring-boot-starter-actuator"
------
runtime 'mysql:mysql-connector-java:5.1.32'
then did a "--refresh-dependencies"
ran the project I get this error:
ERROR org.apache.tomcat.jdbc.pool.ConnectionPool - Unable to create initial connections of pool.
java.sql.SQLException: com.mysql.jdbc.Driver

what am I doing wrong?
on the grails2.x there was a lib folder where I can drop a downloaded mysql-connector-java-5.1.32.jar file but on grails 3.x lib folder is missing. please help.:(
1) Add this to build.gradle
runtime "mysql:mysql-connector-java:5.1.24"
2) then in application.yml file replace H2 database with similar to these lines
dbCreate: update
driverClassName: com.mysql.jdbc.Driver"
dialect: "org.hibernate.dialect.MySQL5InnoDBDialect"
url: jdbc:mysql://localhost/mydbname?useUnicode=yes&characterEncoding=UTF-8"
username: "myusername"
password: "mypassword"

I am trying to get switch user feature in spring security to work. I am using grails 4.0.10 and mysql 8.
I created a sample hello world grails app and followed the switch user guide from the documentation. https://grails.github.io/grails-spring-security-core/4.0.x/index.html#switchUser
If i use the default h2 database then it works but if i switch to the mysql 8 database it is throwing page not found 404 error and it is not switching.
i have published the code in github. here is the link.
https://github.com/sanjaygir/switching
I have created a simple page in secure controller. The page is index.gsp that has a form to switch to another user. Logged in user should be displayed at the top of this page. In bootstrap file i have created two users. one admin and another regular user.
i have a local database with this configuration
dataSource:
dbCreate: create
url: jdbc:mysql://localhost:3307/switch?useUnicode=yes&characterEncoding=UTF-8
username: root
password: password
In order to run this app you need a mysql 8 db running. please change the mysql db name and username and password in the above section in application.yml.
After the app fires please go directly to http://localhost:8080/secure/index and then enter in the textbox "user" and click on the button switch. It will throw an error page not found and if you go back to http://localhost:8080/secure/index you can not see at the top loggedin user name. That means the switch was not successful.
here is the simple code for secure/index.gsp
<%# page contentType="text/html;charset=UTF-8" %>
<html>
<head>
<title></title>
</head>
<body>
<sec:ifLoggedIn>
Logged in as <sec:username/>
</sec:ifLoggedIn>
<form action='${request.contextPath}/login/impersonate' method='POST'>
Switch to user: <input type='text' name='username'/> <br/>
<input type='submit' value='Switch'/>
</form>
</body>
</html>
i hope i have made it clear. this is a simple hello world app created to see switch user feature i n action. I am puzzled why switch user works with default h2 db but not when connected to mysql 8. if anyone have any idea i appreciate your help. Thanks
UPDATE:
Today i switched the database to mysql version 5 and it works.
I changed the following configuration in application.yml
hibernate:
cache:
queries: false
use_second_level_cache: false
use_query_cache: false
dataSource:
pooled: true
jmxExport: true
driverClassName: com.mysql.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
username: root
password: 'password'
environments:
development:
dataSource:
dbCreate: create-drop
url: jdbc:mysql://localhost:3306/switch?useUnicode=yes&characterEncoding=UTF-8
in build.gradle i used
runtime 'mysql:mysql-connector-java:5.1.19'
still i am not sure why it doesnt work in mysql 8.
i finally found the bug. i cannot believe what caused the 404 not found issue.it was a single line in the configuration file.
before the application.yml looked like this

# grails:
it worked after commenting the grails line.
but all the contents of grails block is commented so i am still confused why having grails uncommented would have this big issue. anyways solved after days of hard search!
in my settings I can connect the flyway, it does the migrations more when I use the command maven flyway::repair it only works if I put the bank settings in pom.xml, I would like to have these settings in my .yml but i tried every way and i always get the error:
Unable to connect to the database. Configure the url, user and password!
meu .yml i try this forms
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
password: ${MYSQL_PASSWORD}
url: jdbc:${MYSQL_ENDPOINT}?serverTimezone=UTC&useSSL=false
username: ${MYSQL_USER}

user: ${MYSQL_USER}
password: ${MYSQL_PASSWORD}
driver-class-name: com.mysql.cj.jdbc.Driver

in addition I also tried adding
flyway:
url: jdbc:${MYSQL_ENDPOINT}?serverTimezone=UTC&useSSL=false
user: ${MYSQL_USER}
password: ${MYSQL_PASSWORD}
driver-class-name: com.mysql.cj.jdbc.Driver
but not work. how do you configure it to use the command flyway::repair with the connection data through .yml?
i am creating an application using jhipter,i set mysql for dev and prod when i change the address in the datasource and the pom.xml for liquibase always i have the error Access denied for user 'root'#'localhost' (using password: YES)
I executed also GRANT ALL PRIVILEGES ON . TO 'root'#'localhost' but always the same error.
for pom.xml :

When using a password that contains only numbers, you need to add quotes around it is interpreted as a String value.

i'm trying to connect to my db in codeception. provided following configurations in my api.suite.dist.yml and codeception.dist.yml file (i didn't know where to provide configurations so i provide in both api.suite.dist.yml and codeception.dist.yml)
here is my api.dist.suite.yml

and this is the response i get

Don't use codeception.yml. Configuration in api.suite.yml is enough.
Make sure you use right credentials.

The docs are pretty straightforward for creating multiple datasources using Grails 3, however I cannot get it to work.
When I configure a second datasource, even if I don't use it anywhere in the code, I get the following error:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined
which leads me to believe I have an error in my application.yml file. Here's the relevant code:
dataSources:

jmxExport: true
