I'm using spring boot and using this value in my application.yml
config:
username: abc
password: xyz
In my class, I'm utilizing it this way -
#Value("${config.username}")
private String username;
I'm getting the following error -
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'config.username' in value "${config.username}"
However if I use this in my application.yml file, it works. Can you please tell me what I'm doing wrong here?
config.username: abc
config.password: xyz
check your placeholder is Tab or Space ? make sure no Tab in your yml file.
was facing the same problem when trying to read from application.yml file instead of application.properties file. maven clean & then maven install resolved the issue for me.

I am getting this error when trying to set header that has to be sent to Spring Config Server.
Unrecognized configuration key "quarkus.spring-cloud-config.headers" was provided; it will be ignored; verify that the dependency extension for this configuration is set or that you did not make a typo
# application.properties
quarkus.spring-cloud-config.headers="access_token=12345"
I am not sure what I am doing wrong. Please help. Thanks in advance.
You need to use:
quarkus.spring-cloud-config.headers.access_token=12345
I want to setting the default logging level to error on springboot
enter image description here
But the console still has the dubug and info output. It seems that logging.level.root=error doesn't work.
Be carefull if you are using Spring Boot Devtools, the properties defined in $HOME/.config/spring-boot folder will override all other properties as specified in Spring Boot documentation : https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html
I found a environment variable named debug,even though its value is a string not true,which caused the problem.Actually,I tried to remove the variable before,but I didn't restart the eclipse.Now,I remove the varibale named DEBUG and restart the eclipse,and it success.
I am using to configure spring boot with an external YAML configuration and CMD.
-> application.yml file
spring:
profiles: integration-test
datasource:
driverClassName: ${SPRING_DATASOURCE_DRIVER_CLASS_NAME}
url: ${SPRING_DATASOURCE_URL}
username: ${SPRING_DATASOURCE_USERNAME}
password: ${SPRING_DATASOURCE_PASSWORD}
-> cmd
mvn clean install
-> Result
Caused by: java.lang.IllegalStateException: Cannot load driver class: ${SPRING_DATASOURCE_DRIVER_CLASS_NAME}
Can anyone explain this to me?
When you use the syntax ${}, you are actually telling Spring Boot to use the value of the property whose name is between brackets. In your case, Spring Boot tries to resolve the property SPRING_DATASOURCE_DRIVER_CLASS_NAME. When it fails, it uses the string as is, which leads to the error you mentioned, since no driver exists under the name ${SPRING_DATASOURCE_DRIVER_CLASS_NAME}.
To solve the issue, you can either :
replace the ${} by the real values, e.g. driverClassName: org.postgresql.Driver and do the same for the other properties (url, username and password)
provide properties SPRING_DATASOURCE_DRIVER_CLASS_NAME,SPRING_DATASOURCE_URL and the two others. These can passed in the command line with -D options (e.g. -DSPRING_DATASOURCE_DRIVER_CLASS_NAME=org.postgresql.Driver) or through environment variables. You can look at spring Boot documentation for more details.
Pass those variables in your launch configuration of your program or at commandline when you run your app with java YourMainClass, e.g.
java -DSPRING_DATASOURCE_DRIVER_CLASS_NAME=<full_qualified_name_of_your_jdbc_driver_class> -DSPRING_DATASOURCE_URL=<jdbc_url> YourMainClass
also pass the other two variables the same way, username & password!
your can even set those enviroment variables on OS level, so you don't have to set them each time you start your application...
if your using Spring Boot also have a look at this one: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
I'm trying to create a config file in yaml for my Spring Boot project.
For a test I just setup some values:
user:
test: hello
Now I'm trying to get the information of user.test, but I get the error message Could not resolve placeholder 'user.test' in value "${user.test}"
The strange thing is, that if my config files just has user.test: hello, then everything works fine.
Is there something that I have to setup before to work with yml files as properties?
I'm trying to create a Spring Boot application using sqljdbc4 driver with this config:
spring:
datasource:
url: "jdbc:sqlserver://dbhost:1433;databaseName=test"
username: dbuser
password: dbuser
tomcat:
test-on-borrow: true
validation-query: select 1
But, when I run, I get this error: Unable to detect database type
I was debugging BatchDatabaseInitializer, where error came from, and when it calls JdbcUtils.commonDatabaseName(...), "Microsoft SQL Server" is returned as product name that doesn't match with any DatabaseDriver's product name.
I tried other drivers but they all have the same problem.
Is it a bug?
I'm using Spring Boot 1.5.1-RELEASE.
You need to properly configure your spring.datasource config in application.properties file if you're using spring-batch to create batch jobs. Below is mine ->
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/batch_repo
spring.datasource.username=batch_username
spring.datasource.password=batch_password
spring.datasource.platform=mysql
spring.batch.initialize-schema=always
spring.batch.initialize-schema when configured to "always", will create the necessary spring batch related tables in your schema.
Alternatively, if you assign it to "never", it will refrain from creating the tables. In both these cases your error should get resolved.
Try spring.batch.jdbc.initialize-schema=never in props file. It worked for me in spring-boot v2.6.x
Add this in your Application file within the main function.
#SpringBootApplication(
exclude = {
BatchAutoConfiguration.class,
JmxAutoConfiguration.class
},
excludeName = {
"org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration",
}
)
Put this in your application.properties.
spring.batch.schema=classpath:org/springframework/batch/core/schema-sqlserver.sql
Check your application.properties file like below.
Note: springbatch is my DB name
spring.datasource.url=jdbc:mysql://localhost:3306/springbatch
spring.datasource.username=root
spring.datasource.password=Vishal#123
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.batch.jdbc.initialize-schema=always
