To dig in and see how to debug an application, let's put together something simple: an app that monitors incoming messages from the network. These messages can indicate different levels of network degradation or recovery as reported by various devices.
For a pretty basic JMS-based app that runs on top of ActiveMQ, we can use the following build.gradle build file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.6.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'spring-boot'
jar {
baseName = 'network-monitor'
version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
// tag::clean[]
clean {
delete "activemq-data"
}
// end::clean[]
dependencies {
compile("org.springframework.boot:spring-boot-starter")
compile("org.springframework:spring-jms")
compile...
