Prerequisites

Run tests

Start Redis server

docker run --name redis-session -p 6379:6379 redis

Start PostgreSQL Server in Docker

docker run -d \
 --name spring-session-postgres \
 -e POSTGRES_DB=session_db \
 -e POSTGRES_USER=postgres \
 -e POSTGRES_PASSWORD=password \
 -p 5432:5432 \
 postgres:16

Connect to PostgreSQL with psql

docker run -it --rm \
 --network host \
 postgres:16 \
 psql -h localhost -U postgres -d session_db

Create session_db database

CREATE DATABASE session_db
 WITH
 OWNER = postgres
 TEMPLATE = postgres
 ENCODING = 'UTF-8'
 LC_COLLATE = 'C'
 LC_CTYPE = 'C'
 TABLESPACE = pg_default
 CONNECTION LIMIT = -1
 IS_TEMPLATE = False;

Create Spring Session tables

DROP TABLE IF EXISTS SPRING_SESSION_ATTRIBUTES;
DROP TABLE IF EXISTS SPRING_SESSION;
CREATE TABLE IF NOT EXISTS SPRING_SESSION
(
 PRIMARY_ID CHAR(36) NOT NULL,
 SESSION_ID CHAR(36) NOT NULL,
 CREATION_TIME BIGINT NOT NULL,
 LAST_ACCESS_TIME BIGINT NOT NULL,
 MAX_INACTIVE_INTERVAL INT NOT NULL,
 EXPIRY_TIME BIGINT NOT NULL,
 PRINCIPAL_NAME VARCHAR(100),
 CONSTRAINT SPRING_SESSION_PK PRIMARY KEY (PRIMARY_ID)
);
CREATE UNIQUE INDEX IF NOT EXISTS SPRING_SESSION_IX1 ON SPRING_SESSION (SESSION_ID);
CREATE INDEX IF NOT EXISTS SPRING_SESSION_IX2 ON SPRING_SESSION (EXPIRY_TIME);
CREATE INDEX IF NOT EXISTS SPRING_SESSION_IX3 ON SPRING_SESSION (PRINCIPAL_NAME);
CREATE TABLE IF NOT EXISTS SPRING_SESSION_ATTRIBUTES (
 SESSION_PRIMARY_ID CHAR(36) NOT NULL,
 ATTRIBUTE_NAME VARCHAR(200) NOT NULL,
 ATTRIBUTE_BYTES BYTEA NOT NULL,
 CONSTRAINT SPRING_SESSION_ATTRIBUTES_PK PRIMARY KEY (SESSION_PRIMARY_ID, ATTRIBUTE_NAME),
 CONSTRAINT SPRING_SESSION_ATTRIBUTES_FK FOREIGN KEY (SESSION_PRIMARY_ID) REFERENCES SPRING_SESSION(PRIMARY_ID) ON DELETE CASCADE
);

Verify Spring Session via logs

docker logs spring-session-postgres

Run tests with Maven

mvn clean install -Dspring.profiles.active=test

Common Maven Commands

Compile the project

mvn compile

Install the project to the local repository

mvn clean install

Run tests

mvn test

Run all tests in a specific class

mvn -Dtest=TestClassName test

Run multiple tests (comma-separated)

mvn -Dtest=TestClassName1,TestClassName2,TestClassName3#testMethodName test

Run a specific test method

mvn -Dtest=TestClassName#testMethodName test

Optional: to skip compiling first if already built, use

mvn -DskipCompile=true -Dtest=TestClassName#testMethodName test

mvn -Dtest=TestClassName#testMethodName surefire:test

Package the application into a JAR file

mvn package

Run application

mvn spring-boot:run
