springboot集成netty部署在weblogic上停止再啟動(dòng)時(shí)端口占用

最近手頭上出現(xiàn)了一個(gè)問(wèn)題，將springboot集成netty編寫(xiě)的項(xiàng)目打成war包部署在weblogic11g上時(shí)，使用weblogic啟動(dòng)一次項(xiàng)目再關(guān)閉項(xiàng)目，再次啟動(dòng)的時(shí)候netty就發(fā)生了端口占用問(wèn)題，經(jīng)檢查發(fā)現(xiàn)是weblogic關(guān)閉項(xiàng)目的時(shí)候netty并沒(méi)有關(guān)閉，使得項(xiàng)目再次啟動(dòng)初始化netty的時(shí)候報(bào)錯(cuò)，請(qǐng)問(wèn)有什么好的解決辦法嗎？
