LENA

SpringBoot 기반 애플리케이션 LENA 배포 시 가이드

탕탕자·2026년 9월 22일·조회 5

개요

A사의 LENA 도입을 진행 예정이며, 현재 로컬 개발 환경에서 SpringBoot 3.5.2 버전을 사용 중에 있다.

이에 현재 로컬에서 Embedded Tomcat 기반의 SpringBoot 애플리케이션을 WAR로 변환하여 설치형 LENA로 배포할 수 있는 환경을 만들어야 한다.

이를 위해서 아래 2개 작업이 선행되어야 한다.

  • JAR 형태의 자바 실행 환경을 WAR로 Export하여 LENA WAS에 배포

  • SpringBoot Hikari풀(내장 방식)의 DB 연결을 LENA 데이터소스 방식으로 변경

가이드

서버 및 솔루션 버전 정보

  • OS: Windows 11

  • Java: OpenJDK 21

  • LENA 1.3.4.7 (EN10) Tomcat 10.1.55 Based

  • SpringBoot 3.5.2

  • DBMS SQL Server 2025

  • jdbc driver(mssql-jdbc-13.4.0.jre11.jar)

  • Embedded Tomcat Port: 8080

  • LENA WAS Port: 10000

SpringBoot(Embedded Tomcat) + MS SQL Server 2025 + JDK21 구성

1. SpringBoot 디렉토리 구조

app.yml

1. Spring Boot는 application.yml(공통)을 먼저 읽고
2. spring.profiles.active 값에 해당하는 application-{프로필명}.yml을 추가로 읽어서 덮어씁니다

※ mvn spring-boot:run -Dspring-boot.run.profiles=dev → mvn 실행 예시

웹 브라우저 호출하여 정상 서비스 확인

Export WAR + LENA + HikariCP 사용 시 가이드

사전 준비 사항

  • Windows 환경, LENA 1.3.4.7 설치

  • MS SQL Server 2025 구성  

1. pom.xml 수정

1.1. packaging 추가

<groupId>com.example</groupId>
<artifactId>db-test-app</artifactId>
<packaging>war</packaging> ← 추가

1.2. spring-boot-starter-web 밑에 Tomcat 의존성 추가

       <!-- WAR로 배포 시 외부 WAS의 서블릿 컨테이너를 쓰도록 함
             (내장 톰캣은 빌드에만 포함되고 실제 배포에는 제외됨) -->

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

2. ServletInitializer.java 파일 추가

Spring Boot를 WAR로 배포하려면, 외부 WAS가 애플리케이션을 어떻게 실행시킬지 알려주는 클래스가 하나 필요합니다.

※ 소스 경로: src/main/java/com/example/dbtest/ServletInitializer.java

package com.example.dbtest;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DbTestAppApplication.class);
    }

}

3. mvn clean & package

mvn package (WAR 패키징)

  • 우측 mvn 아이콘 선택 > 라이프사이클 > package 버튼 클릭하여 target 경로에 WAR 파일 생성

4. LENA APP 배포 및 서비스 호출

  • Manager > Resource > ROOT.war 애플리케이션 배포

  • 서비스 호출하여 정상 서비스 확인

5. 진단 > 데이터소스 모니터링

  • spring.active.profile 설정 없을 경우 (dev가 default)

    • 데이터소스 커넥션 풀이 개발기 설정에 맞게 세팅

  • spring.active.profile=prod 설정 시

    • 데이터소스 커넥션 풀이 운영기 설정에 맞게 세팅

Export WAR + LENA Datasource 사용 시 가이드

사전 준비 사항

  • Windows 환경, LENA 1.3.4.7 설치

  • MS SQL Server 2025 구성  

1. pom.xml 수정

1.1. packaging 추가

<groupId>com.example</groupId>
<artifactId>db-test-app</artifactId>
<packaging>war</packaging> ← 추가

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DbTestAppApplication.class);
    }

}

3. application.yml 파일 수정

application.yml (공통)
# DB 연결 정보와 HikariCP 관련 설정이 모두 제거 됨.
------------------------
server:
  port: 8080

spring:
  application:
    name: db-test-app

  profiles:
    active: dev


application-prod.yml (운영)
# spring.datasource.jndi-name을 통해 외부 WAS의 JNDI에 등록된 데이터소스와 연결한다.
------------------------
spring:
  datasource:
    jndi-name: java:comp/env/jdbc/test
# Hikari가 커넥션 풀을 만드는 게 아니라, **LENA의 server.xml/context.xml에 정의된 DataSource를 JNDI로 조회(lookup)**해서 사용함. 
# Spring Boot는 spring.datasource.jndi-name 속성만 있으면 자동으로 Hikari 대신 JNDI 조회를 사용함.

4. LENA 데이터소스 등록

  • JNDI Name: jdbc/test 

5. mvn clean & package

mvn clean
