1. application
.\gradlew runnormal!
2. war
.\gradlew warDrag the war package to the tomcat webapps directory.
Notice Application.kt:
internal fun main() {
val port = 8080
// if tomcat server war
val contextPath = "/ssm-mvc" // <-
// if jar
// val contextPath = ""
...
}normal!
3. jar
This is a standard Java Web MVC project using embedded Tomcat. The main startup class Application.kt is as follows:
package edu.tyut
import org.apache.catalina.connector.Connector
import org.apache.catalina.startup.Tomcat
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import java.io.File
private val logger: Logger = LoggerFactory.getLogger("Application")
internal fun main() {
val port = 8080
// if tomcat server war
// val contextPath = "/ssm-mvc"
// if jar
val contextPath = ""
val webAppDir = File("src/main/webapp")
val tomcatBaseDir = "build/tomcat"
val tomcat = Tomcat()
tomcat.setPort(port)
tomcat.setBaseDir(tomcatBaseDir)
logger.info("Starting tomcat on Port: {}", port)
logger.info("Starting tomcat on contextPath: {}", contextPath)
logger.info("Starting tomcat on webAppDir: {}", webAppDir.absolutePath)
logger.info("Starting tomcat on tomcatBaseDir: {}", tomcatBaseDir)
tomcat.addWebapp(contextPath, webAppDir.absolutePath)
tomcat.start()
val connector: Connector = tomcat.connector
logger.info("Starting success connector: $connector ...")
tomcat.server.await()
}
The script for packaging into a JAR is as follows:
tasks.jar {
archiveFileName.set("${project.name}.jar")
manifest {
attributes["Main-Class"] = "edu.tyut.ApplicationKt"
}
from(configurations.runtimeClasspath.get().map { zipTree(it) }) {
exclude("META-INF/*.RSA", "META-INF/*.SF", "META-INF/*.DSA")
}
duplicatesStrategy = DuplicatesStrategy.EXCLUDE
}packaging and run
.\gradlew jar
java -jar ssm-mvc.jarUnfortunately, the embedded Tomcat failed to load the WebApplicationInitializer implementation (specifically edu.tyut.config.WebInitializer), resulting in only the startup logs from Application.kt being visible.
The jar package doesn't work properly
Access the URL http://localhost:8080/hello in a browser, is 404
Expectation
The jar package works normally. Access the URL http://localhost:8080/hello in a browser, is 200.
