I try to config the oracle's connection by using application.properties file but it gives me an IllegalArgumentException with message "Invalid URL: r2dbc:oracle:thin:#localhost:1521:orcl", it was fine when I set with the MySql URL. Here is my application.properties:
spring.r2dbc.url=r2dbc:oracle:thin:#localhost:1521:orcl
spring.r2dbc.username=account
spring.r2dbc.password=account
please give me an explanation or solution for this, thank you.
Please try with
spring.r2dbc.url=r2dbc:oracle:thin://localhost:1521:orcl

Developing web application I'd like to use an embedded database to store data. However instead of proposed in-memory databases I`d like to prefer to use custom one. My choice is MariaDB. I have been ruled with this article how to get MariaDB as embedded database in my project, everything is fine, database appears, except one thing: I cannot change an encoding for my tables values.
I tried to set additional application properties in my application.yml file, tried to complete connection string with parameters of specifying encoding, but all those stuff didn't work unfortunately :(
May any of you have ever faced with such problem and can help me? Thank you in advance!
My current application.yml is following:
mariaDB4j:
dataDir: ./localMariaDB
port: 3307
databaseName: embeddedDB
spring:
datasource:
url: jdbc:mariaDB://localhost:3307/
username: root
password:
driver-class-name: org.mariadb.jdbc.Driver
jpa:
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
hibernate:
ddl-auto: create
And finally I get exception bellow:
Caused by: java.sql.SQLException: Incorrect string value: '\xD0\x92 \xD1\x80\xD0...' for column 'current_status' at row 1
at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.readErrorPacket(AbstractQueryProtocol.java:1688) ~[mariadb-java-client-2.6.2.jar:na]

By the way, when I run the application, the connection string which I get looks like jdbc:mysql://localhost:3307/embeddedDB.
I am confused why there is :mysql: instead of :mariadb: as specified in my connection properties. Does it have an influence on my database behavior?
So, I have found the resolution to my issue.
It appeared as usual very simple :)
To change standard character encoding, which MariaDB proposes, I had to specify additional configuration properties before setting up the MariaDB's DataSource.
As this source provides to configure MariaDBSpringService entity to further use in DataSourceconfiguration, it is necessary to extend it (MariaDBSpringService) with some character encoding description utils. So, to specify custom encoding (i.e. to change standard one) I've just added the following lines of code to MariaDBSpringService bean:
service.getConfiguration().addArg("--character-set-server=utf8mb4");
service.getConfiguration().addArg("--collation-server=utf8mb4_general_ci");
In general, the full bean declaration is below:
#Bean
public MariaDB4jSpringService mariaDB4jSpringService(){
MariaDB4jSpringService service = new MariaDB4jSpringService();
service.getConfiguration().addArg("--character-set-server=utf8mb4");
service.getConfiguration().addArg("--collation-server=utf8mb4_general_ci");
return service;
}
Hope, this will help somebody, who further can possibly face with such issue))
Thanks to everybody, who tried to help me!
for days now I've been trying to get a simple H2 / R2dbc database running in Spring boot with WebFlux. The app starts up just fine but when I call the /todos endpoint to get all the objects in the database I get the following error:
reactor.core.Exceptions$ErrorCallbackNotImplemented: org.springframework.data.r2dbc.BadSqlGrammarException: executeMany; bad SQL grammar [SELECT TODO.* FROM TODO]; nested exception is io.r2dbc.spi.R2dbcBadGrammarException: [42102] [42S02] Table "TODO" not found; SQL statement:
SELECT TODO.* FROM TODO [42102-200]
My understanding is that if I add a schema.sql file on the class path with a create table command it will use that to create the table on startup, but it does not look like that is working. Any ideas on what I may be doing wrong? Any help would be appreciated, what would like to get to is a working mysql/r2dbc example, if someone could point me to one.
All the code is located at: https://gitlab.com/vanfleet/test-r2dbc-h2
It is query issue. Run same query in editor.
Trying to use encrypted database password to connect to database using spring auto configuration
I am using Spring auto configuration to connect to database. For that i added below properties in properties file:
spring.datasource.url=jdbc:oracle:thin:#ABCDE2D.com:1888:ABCDE2D1
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driver-class-oracle.jdbc.driver.OracleDriver
In my dao class, i have #Autowired NamedParameterJdbcTemplate and using it directly to get data from database.
Till here it is working fine.
Now i need to encrypt the password in properties file.
For that i did the below:
Added jasypt-spring-boot-starter in pom
Added spring.datasource.password=ENC(NoIv2c+WQYF3LenN0tDYPA==) in properties file
Added jasypt.encryptor.password=key in properties file
Now i am getting the below error:
Failed to bind properties under 'spring.datasource.password' to
java.lang.String:
Reason: Failed to bind properties under 'spring.datasource.password' to
java.lang.String
I'm providing some basic guide as follows.
You need to add following two parameters in to property file in order application to work properly. This is assuming you are encrypting using default encryption algorithm. If you are useing some other, then make sure to change it accordingly.
jasypt.encryptor.iv-generator-classname=org.jasypt.iv.NoIvGenerator
jasypt.encryptor.algorithm=PBEWithMD5AndDES
You can refer to more details
https://nirmalbalasooriya.blogspot.com/2020/02/spring-boot-property-encryption-using.html
In my case I was giving wrong jasypt.encryptor.password.
For Example given below is properties I have set in my application.properties:
jasypt.encryptor.password=abc
instead abc I gave jasypt as my secret key while encrypting the password so the encripted password is wrong. Then it throwing this error.
Later I realised and found that the key is not correct.
Then gave the right key i.e., abc.Then it worked for me.
Silly mistake but it cost me 4 hours. Hope it will be useful for others.
If you are using jasypt dependency, make sure that:
spring.datasource.password = Enc
and
jasypt.encryptor.password = key
where Enc is encrypted password and key is the key which you used to generate the encrypted password.
My table data got deleted when i restart my spring boot application after changing the value of 'spring.jpa.hibernate.ddl-auto' to 'create' from 'verify'. why it is so? what should i do to get my data back?
I could see some drop query executing in my IDE console. Why it happened? can someone please explain?
Make the following change in application.properties
spring.jpa.hibernate.ddl-auto=none
You can read the official document of spring-boot.And the property is related to hibernate.hbm2ddl.auto in hibernate configuration.
Just change table name:
#Entity
#Table(name = "hms_pinlocator")
I try to set up a local development infrastructure and I want to use HSQLDB as a datasource with my WAS 6.1. I already know that I have to use Apache DBCP to get a connection pooling, but I'm stuck when my application tries to get the first connection.
What I've done
In WAS I created a JDBC provider with the class org.apache.commons.dbcp.cpdsadapter.DriverAdapterCPDS and removed everything from the classpath input field. Then I put commons-dbcp.jar, commons-pool.jar and hsqldb.jar in MYAPPSERVERDIRECTORY/lib/ext.
Then I created a new datasource with that provider. I added the following custom properties:
driver=org.hsqldb.jdbc.JDBCDriver
url=jdbc:hsqldb:file:///C:/mydatabase.db;shutdown=true
user=SA
password=
My Problem
When I run my application and the first connection to the database is made, I get the following exception:

Any tips on this? I suspect I'm using a wrong class from hsqldb, or maybe my JDBC url is wrong...
In the example given in BDCP docs, the org.hsqldb.jdbcDriver class is used as the driver. The org.hsqldb.jdbc.JDBCDriver is supported only in HSQLDB 2.x, but the other class is supported by all versions of HSQLDB.
