Configure HikariCP in Spring Boot with JTDS

Question

I want to add a connection pool to my existing web application, which has been made using Spring Boot 1.5.1.

The datasource configuration is made in application.properties as follows:

spring.datasource.url=jdbc:jtds:sqlserver://localhost:1433;databaseName=MyDatabase;instance=SQLServer2014;
spring.datasource.username=myuser
spring.datasource.password=passwd
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update

I don't need to make any further configuration, with this is enough.

It isn't clear enough in the official docs, although parameters are shown, nor in the Spring Boot docs.

So, I've been looking for solutions over there (this one, this one too...).

I've made several trials, but everytime I run the app, exceptions regarding HikariCP are thrown.

When adding spring.datasource.type=com.zaxxer.hikari.HikariDataSource, the following exception is thrown:

So, which is the simplest way to add hikaricp to my application.properties?

Answer 1

For using multiple datasources (Spring Boot 2.0), I had to do the following to get this to work (setting spring.datasource.hikari.connection-test-query property only worked when using a single datasource):

@Configuration
public class DataConfig {
    @Bean
    @Primary
    @ConfigurationProperties(prefix="spring.datasource")
    public DataSource primaryDataSource() {
        HikariDataSource ds = (HikariDataSource) DataSourceBuilder.create().build();

        ds.setConnectionTestQuery("SELECT 1");

        return ds;
    }

    @Bean(name="secondDataSource")
    @ConfigurationProperties(prefix="spring.datasource.second")
    public DataSource secondDataSource() {
        HikariDataSource ds = (HikariDataSource) DataSourceBuilder.create().build();

        ds.setConnectionTestQuery("SELECT 1");

        return ds;
    }

    @Bean(name="primaryJdbcTemplate")
    public JdbcTemplate primaryJdbcTemplate(DataSource primaryDataSource) {
        return new JdbcTemplate(primaryDataSource);
    }

    @Bean(name="secondJdbcTemplate")
    public JdbcTemplate secondJdbcTemplate(@Qualifier("secondDataSource") DataSource secondDataSource) {
        return new JdbcTemplate(secondDataSource);
    }
}

Answer 2

I ran into the same problem and found the solution from this discussion. It looks like, before doing any further configurations Hikari CP tests the validity of the connection by executing a test query which is missing in this case. So as suggested by the earlier answer, you should add one test query in your application.properties file. If you are using Oracle or mySql then you can use the following query instead (as SELECT 1 doesn't work here):

spring.datasource.hikari.connection-test-query=SELECT 1 FROM DUAL

Note: DUAL is a special one-row and one-column table present in Oracle and other databases. Thus it can be readily used to execute a simple test-query.

Answer 3

You are getting below error.

Caused by: java.lang.AbstractMethodError: null at net.sourceforge.jtds.jdbc.JtdsConnection.isValid(JtdsConnection.java:2833)

Issue is that net.sourceforge.jtds.jdbc.JtdsConnection doesn't implement isValid so you need to specify a connection-test-query to ensure that isValid method isn't called. Try by adding below property in your application.properties file.

spring.datasource.hikari.connection-test-query=SELECT 1
