this is my code but the eclipse connecting some other database and giving below error
java.lang.AssertionError: Failed due to Error:

operation: Cannot open connection; uncategorized SQLException for SQL

It seems that you have wrong url, put the url like this
<property name="url" value="jdbc:mysql://pc123456:3306/xxx"/>
Where xxx is the db name of MySql.
And make sure with the given user name you are able to login in the MySql db

I'm getting this exception in production. Things are quiet for weeks at a time and then we get a "rash" of them all of a sudden:
Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException:
Failed to obtain JDBC Connection; nested exception is
java.sql.SQLTransientConnectionException: HikariPool-1 - Connection is
not available, request timed out after 1031ms.
STEPS TAKEN TO INVESTIGATE THE PROBLEM:
This symptom has well-known possible causes, which I have checked:
JdbcTemplate is being used correctly, checked: Spring jdbctemplate is it required to close the connection
Using try-with-resource to ensure Connections are closed, checked: Hikari Pool Connection is not available Error
Database server can support the load, checked (server not busy at all, checked top and pg_activity and netstat -- really not much is going on): Hikari connection pool, Connection is not available
What else could be causing this?

I am new to hibernate, and I have been tasked with changing the ConnectionProvider from the hibernate default CP to either Hikari (preferred) or C3P0 in a legacy Java application that does not use maven as a repository. The database is PostgreSQL. The hibernate version is hibernate-release-5.2.10.Final. I have added hibernate-hikaricp-5.2.10.Final.jar to the classpath.
I have a pre-existing xml configuration file for hibernate. This has been working for several years, but the project wants to change to a "production ready connection pool". I have added/modified properties for the connection provider as follows:
<property name="hibernate.connection.provider_class">org.hibernate.hikaricp.internal.HikariCPConnectionProvider</property>
<property name="hibernate.hikari.minimumIdle">5</property>
<property name="hibernate.hikari.maximumPoolSize">20</property>
<property name="hibernate.hikari.idleTimeout">30000</property>
I am getting the following StrategySelectionException (long stack trace reduced to exceptions/causes ... more information available if necessary).
Exception in thread "DatabaseCache initialize thread" org.hibernate.service.spi.ServiceException: Unable to
create requested service [org.hibernate.engine.jdbc.connections.spi.ConnectionProvider]
...
Caused by: org.hibernate.boot.registry.selector.spi.StrategySelectionException: Unable to resolve name [org.hibernate.hikaricp.internal.HikariCPConnectionProvider] as strategy [org.hibernate.engine.jdbc.connections.spi.ConnectionProvider]
I made one other change, after first seeing the exception. I added the following property, but it made no difference.
<property name="hibernate.implicit_naming_strategy">default</property>
The full configuration, with some information provided as variables replaced during build, is:
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hibernate.implicit_naming_strategy">default</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.connection.provider_class">org.hibernate.hikaricp.internal.HikariCPConnectionProvider</property>
<property name="hibernate.hikari.minimumIdle">5</property>
<property name="hibernate.hikari.maximumPoolSize">20</property>
<property name="hibernate.hikari.idleTimeout">30000</property>
<property name="hibernate.connection.username">${db_user_name}</property>
<property name="hibernate.connection.password"></property>
<property name="hibernate.connection.url">${db_connection_url}</property>
<property name="hibernate.hbm2ddl.auto">none</property>
<property name="hibernate.connection.autocommit">false</property>

<property name="hibernate.generate_statistics">false</property> <!-- This affects performance, use only in development -->
<property name="show_sql">false</property>
</session-factory>
</hibernate-configuration>
Any strategies :D to address this would be welcome. Thanks.
I am connecting to an external database with a class that extends JdbcTemplate. My problem is that I can't use the globalProperties of the Groovy API because of the Jdbc.
I added these properties I needed in the server-config.properties:
studio.db.driverClassName
studio.db.url
studio.db.username
studio.db.password
I am trying to access them in my application-context.xml with this:
<bean id="jdbc" class="com.dbJdbcTemplate">
<constructor-arg ref="datasource"/>
</bean>
<bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="url" value="${studio.db.url}"/>
<property name="driverClassName" value="${studio.db.driverClassName}"/>
<property name="username" value="${studio.db.username}"/>
<property name="password" value="${studio.db.password}"/>
</bean>
I receive this error:
Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not
get JDBC Connection; nested exception
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class '${studio.db.driverClassName}'
How do I access the properties from my bean correctly?
Add a <bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer" parent="crafter.properties"/> in your site application-context.xml, like is shown in here https://docs.craftercms.org/en/3.0/site-administrators/engine/engine-site-configuration.html#id3. That lines gives you access to Engine's global properties.

This is the key part of your stack trace:
FATAL: the database system is starting up
It means that the PostgreSQL server is starting or restarting and not ready to accept connections yet.
You should check the PostgreSQL server log to find the cause of this unexpected start.
Chances are that it is a restart caused by a crashing PostgreSQL server process. Such crashes can be caused (in rough order of likelihood) by buggy server extensions, buggy hardware or PostgreSQL bugs.
I'm looking at porting a Java-Spring application from Oracle to PostgreSQL. I'm running into a big difference between the way the transactions are handled. I'm having a problem with this statement:
public void upsert(String username, String pName, String pValue) {
Object[] args = { pValue, pName, username };
try {
jdbcTemplate.update(INSERT_USER_PREFERENCE, args);
} catch (DuplicateKeyException e) {
jdbcTemplate.update(UPDATE_USER_PREFERENCE, args);
}
}
This works fine in Oracle but in PostgreSQL this fails because PostgreSQL does not allow further commands in a transaction if there is a failure and it wants you to rollback or commit
(SQL state [25P02]; error code [0]; ERROR: current transaction is aborted, commands ignored until end of transaction block; nested exception is org.postgresql.util.PSQLException: ERROR: current transaction is aborted, commands ignored until end of transaction block)
This seems pretty unique to PostgreSQL. Is there a way to make PostgreSQL behave in the same way as Oracle (and other databases)?
