? websocket配置 ?
- 首先2022-06-10下载下来的源码心跳模块的日志打印都是关掉的,所以咱们看不出来心跳传送,这里记录下怎么把日志放开调试的步骤
- 到官方源码看websocket配置代码,位置在这:
ant-design-vue-jeecg/src/components/tools/HeaderNotice.vue
- 注意这几个被注释的地方
- 看后端websocket配置
jeecg-boot/jeecg-boot-module-system/src/main/java/org/jeecg/modules/message/websocket/WebSocket.java
- 后端无需改什么代码,可以启动调试下,多在前后端进行debugger即可,如有疑问可留言交流哈,附上前端改动及弹窗代码
