To externalize static resources folder you can run app without public folder packaged and later create such folder with needed content near to jar file
by default spring is using folders
static/ and public/:spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
so you cd to application jar file folder and can create here needed one:
mkdir -p demo cd demo/ curl https://start.spring.io/starter.zip -d dependencies=web | tar -xzvf - bash ./mvnw clean package cd target/ mkdir -p public echo "<html><body>Hello</body></html>" > ./public/index.html java -jar *.jar http :8080 tree . . ├── demo-0.0.1-SNAPSHOT.jar └── public └── index.html
or create public folder where you are relatively to jar file (public folder located in
$PWD):mkdir -p demo
cd demo/
curl https://start.spring.io/starter.zip -d dependencies=web | tar -xzvf -
bash ./mvnw clean package
mkdir -p public
echo "<html><body>Hello</body></html>" > ./public/index.html
java -jar ./target/*.jar
http :8080
tree .
.
├── public
│ └── index.html
└── target
└── demo-0.0.1-SNAPSHOT.jar
or simply use spring boot executable launch scripts (public folder located near jar-file):
wget https://start.spring.io/starter.zip -O /tmp/gradle-demo.zip --post-data="dependencies=web&type=gradle-project"
mkdir -p /tmp/gradle-demo
unzip /tmp/gradle-demo.zip -d /tmp/gradle-demo
cd /tmp/gradle-demo/
echo 'bootJar { launchScript() }' >> build.gradle
bash gradlew build
bash ./build/libs/*.jar
http :8080 || true
mkdir -p ./build/libs/public
echo "<html><body>Hello</body></html>" > ./build/libs/public/index.html
bash ./build/libs/*.jar
http :8080
