Hello World模式
环境搭建
这里使用gradle项目
apply plugin: 'eclipse' apply plugin: 'maven' apply plugin: 'java' sourceCompatibility = 1.8 [compileJava,compileTestJava,javadoc]*.options*.encoding = 'UTF-8' repositories { maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'} mavenCentral() jcenter() } dependencies { compile group: 'com.rabbitmq', name: 'amqp-client', version: '4.1.0' compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.25' }
Hello World模式(点对点)
