项目结构

如何快速上手

http篇

1、controller包就相当于@RestController，这里返回了一个Person对象，当你需要新建一个接口时，再新写一个func仿照下面的方法就行了

package controllerimport ("net/http""testproject12/common""testproject12/entity""testproject12/util"
)// PersonHandler 无入参，返回person类
func PersonHandler(w http.ResponseWriter, r *http.Request) {// 创建一个Person对象person := entity.Person{Name:  "John Doe",Age:   30,Title: "Software Engineer",}messageHex := "FFFFFF"util.SendHexMessageToAllUser(messageHex)// 封装为JSON格式的CommonResult并写入响应体common.WriteJSONResponse(w, http.StatusOK, common.DefaultSuccessMsg, person)
}

2、router.go负责配置路由，下面的代码中，server.AddRoute的key相当于@RequestMapping(“/person”)，value是上面文件在controller包下，方法是PersonHandler

package routerimport ("testproject12/controller""testproject12/httpServer"
)func SetupRoutes(server *httpServer.HTTPServer) {// 添加路由server.AddRoute("/person", controller.PersonHandler)// Add more routes as needed
}

tcp篇

用SocketTool新建一个客户端


http://localhost:8080/person

服务器收到数据FFFFFF

总结

实现了http请求与tcp请求，如果有需要的话请fork我的github代码
