SpringBoot disable all default database related configuration.

 Hi Folks,

Today, I'm sharing my working experience to disable the default springboot database related configuration.

This can be achieved via two mechanism.

Mechanism 1: Annotations

@SpringBootApplication
@EnableAutoConfiguration(exclude = {
    DataSourceAutoConfiguration.class,
    DataSourceTransactionManagerAutoConfiguration.class,
    HibernateJpaAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

Mechanism 2 : application.properties.

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration, org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

Spring Error: The prefix "util" for element "util:list" is not bound.

Hi Friends,

Today I'm sharing my Spring learning to how to resolve the error

The prefix "util" for element "util:list" is not bound.

Open spring.xml and add the following lines in the beans tag

xmlns:util="http://www.springframework.org/schema/util"

http://www.springframework.org/schema/util 
http://www.springframework.org/schema/util/spring-util.xsd"
