我正在尝试将我的 java 应用程序部署在 tomcat 服务器（在 Windows 中）上，但出现以下错误。请帮助我就以下连接错误提供一些指导。我有管理员权限，服务器在本地运行。

C:\builds>cap local deploy
DL is deprecated, please use Fiddle

  * 2013-04-01 14:19:06 executing `deploy'

请在下面找到使用的部署脚本

set :application, "myApp"
#set :scm, "git"
set :repository, "C:/_Savita/app/my-app"
#set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true 

task :local do
    roles.clear
    server "localhost", :app 
    set :user, "Savita Doddamani" 
    set :java_home, "C:/Program Files (x86)/Java/jdk1.6.0_25" 
    set :tomcat_home, "C:/Program Files (x86)/Apache Software Foundation/Tomcat 6.0"
    set :tomcat_manager, "user"
    set :tomcat_manager_password, "pwd"
    set :maven_home, "C:/_Savita/softwares/apache-maven-2.2.1"
    set :deploy_to, "C:/builds/" 
    set :use_sudo, false
    namespace :tomcat do
      task :deploy do
        puts "==================Building with Maven======================" #Line 22
        run "export JAVA_HOME=#{java_home} && cd #{deploy_to}/ && #{maven_home}/bin/mvn clean install package -DskipTests"
        puts "==================Undeploy war======================"#Line 24
        run "curl --user #{tomcat_manager}:#{tomcat_manager_password} http://$CAPISTRANO:HOST$:8080/manager/text/undeploy?path=/#{application}"
        puts "==================Deploy war to Tomcat======================" #Line 26
        run "curl --upload-file #{deploy_to}/current/target/dist/local/#{application}*.war --user #{tomcat_manager}:#{tomcat_manager_password} http://$CAPISTRANO:HOST$:8080/manager/text/deploy?path=/#{application}"
      end
    end
    after "deploy", "tomcat:deploy" #Line 30
    after "tomcat:deploy", "deploy:cleanup" # keep only the last 5 releases
end

ECONNREFUSED是connect(2)系统调用的返回。这意味着服务器进程没有在 TCP 端口 8080 上侦听。Java 需要时间来启动，您可能试图通过curl太快进行连接，或者您尚未将 Tomcat 配置为侦听端口 8080，或者您根本没有启动 Tomcat。
