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‘
}
