BoneCP Connection Pooling Example

BoneCP Connection Pooling Example exaplains about how to create and configure a Connection pool using BoneCP Datasource

Creating and establishing a database connections are relatively very expensive because of establishing a network connection, initializng database session, authorization in the back end database etc.

Due to this issues, it is good practice to use a connection pool in your applications in order to increase the performance and scalability. By using Connection Pool, you can re-use already existing connections and prepared statements, so that you can avoid the cost of establishing the connection.

BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library. If you are familiar with C3P0 and DBCP then you already know what this means. For the rest, this is a library that will manage a database connection for you to get faster database access in your application

Required Libraries

You need to download

  1. BoneCP
  2. Guava
  3. SLF4J

Following jar must be in classpath

  1. bonecp-0.7.1.RELEASE.jar
  2. guava-16.0.1.jar
  3. slf4j-api-1.7.6.jar
  4. slf4j-jdk14-1.7.6.jar
  5. mysql-connector-java-5.1.28-bin.jar

Create Table Structure

CREATE TABLE `employee` (
  `EMPLOYEEID` bigint(20) NOT NULL AUTO_INCREMENT,
  `EMPLOYEENAME` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`EMPLOYEEID`)
);
