java – HotSwaping代码到“mvnDebug tomcat：run”

通常我使用mvnDebug tomcat：run启动tomcat.

代码更改后我需要使用mvn tomcat：redeploy.

这是次优的,因为我经常只改变现有方法体的内容.

我可以将方法的主体HotSwap到运行时,并作为回退进行热重新部署吗？

不幸的是,我发现像maven-hotswap-plugin一样.

faces-config.xml中

... <application>
  <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
  <locale-config>
   <default-locale>de_DE</default-locale>
  </locale-config>
  <resource-bundle>
   <base-name>Message</base-name>
   <var>message</var>
  </resource-bundle>
  <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
 </application>
</faces-config>

web.xml中：

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
</listener>

解决方法

您可以使用 Jrebel – 它完全按照您的预期工作.您只需要指定javaagent,它将在运行时重新加载所有类和框架更改.它也适用于远程服务器

要将其与maven项目集成,您必须添加jrebel-maven-plugin,这将生成所有配置(rebel.xml)文件.

如果没有JRebel,您可以使用标准的HotSwap机制,但它只允许重新加载方法体
