方案一:Jrebel(推荐)
IDE(STS或Idea)安装Jrebel插件

下面介绍如何获取Jrebel的激活码,注意Jrebel激活码使用时会连接服务器实时监测,一个账号只允许一个终端使用;

  1. 打开https://my.jrebel.com(需要翻墙),需要第三方facebook或twitter账号登录后进行授权
    title
  2. 需要填写个人资料(手机什么的可以瞎填目前没有做校验);
    title
    title
  3. 注册成功后就可以获取到免费的激活码
    title
  4. 输入IDE->Jrebel->Activation code完成激活;

使用Jrebel热启动:

注意:idea修改源码后热部署前需要触发重新编译快捷键ctrl+f9

方案二:spring-loaded
spring-loaded有两种集成方式

  1. spring-loaded热插拔设置,首先下载springloaded然后配置JVM启动参数
    Run As->Run Configurations…->Java Application->->Arguments(VM arguments)
    add:
    -javaagent:/Users/Robert/.springloaded/springloaded-1.2.6.RELEASE.jar -noverify

  2. 使用maven pluin,然后使用 mvn spring-boot:run启动工程



    org.springframework.boot
    spring-boot-maven-plugin


    org.springframework
    springloaded
    1.2.3.RELEASE



个人推荐使用Jrebel,功能比springloaded更强大也更稳定,支持热部署class和部分配置文件及XML(具体可以自行尝试),最新版的Jrebel可能不支持免费的注册码
