demo目录：
upload文件夹主要放置上传的头像文件，main是主文件，所有效果如下：

删除：
新增/修改会员：
app.conf配置文件：
appname = easyui_crud httpport = 8080 runmode = dev #数据库配置 db.host = 192.168.20.132 db.port = 3306 db.user = root db.pass = root db.name = test db.timezone = Asia/Shanghai
base.go主要放置一些公共操作：
package controllers
import (
"github.com/astaxie/beego"
)
type BaseController struct {
beego.Controller
}
func (this *BaseController) Rsp(status bool, str string) {
this.Data["json"] = &map[string]interface{}{"succ": status, "msg": str}
this.ServeJSON()
}
userController：
package controllers
import (
m "easyui_crud/models"
"fmt"
)
type UserController struct {
BaseController
}
func (this *UserController) Index() {
user := this.GetSession("userinfo")
if user != nil {
this.Data["userinfo"] = user
this.TplName = "main.html"
return
}
this.Redirect("/", 302)
}
func (this *UserController) UserIndex() {
this.TplName = "user/usermanage.html"
}
func (this *UserController) UserList() {
page, _ := this.GetInt64("page")
pageSize, _ := this.GetInt64("rows")
u := m.User{}
if this.GetString("id") != "" {
u.Id, _ = this.GetInt("id")
}
if this.GetString("name") != "" {
u.Name = this.GetString("name")
}
if this.GetString("phone") != "" {
u.Phone = this.GetString("phone")
}
nodes, cnt := m.GetUserList(page, pageSize, &u)
this.Data["json"] = &map[string]interface{}{"total": cnt, "rows": &nodes}
this.ServeJSON()
}
func (this *UserController) UserDel() {
idstr := this.GetString("ids")
err := m.DelUser(idstr)
if err != nil {
this.Rsp(false, err.Error())
} else {
this.Rsp(true, "删除成功")
}
}
func (this *UserController) UserAdd() {
u := m.User{}
u.Id, _ = this.GetInt("Id")
if err := this.ParseForm(&u); err != nil {
this.Rsp(false, err.Error())
return
}
id, err := m.AddUser(&u)
if err == nil && id > 0 {
this.Rsp(true, "新增成功")
return
} else {
this.Rsp(false, err.Error())
return
}
}
func (this *UserController) UserUpdate() {
u := m.User{}
if err := this.ParseForm(&u); err != nil {
this.Rsp(false, err.Error())
return
}
id, err := m.UpdateUser(&u)
if err == nil && id > 0 {
this.Rsp(true, "修改成功")
return
} else {
this.Rsp(false, err.Error())
return
}
}
func (this *UserController) UserUpload() {
f, fh, err := this.GetFile("uploadFile")
defer f.Close()
if err != nil {
fmt.Println("get file error ", err)
this.Data["json"] = &map[string]interface{}{"path": "", "succ": false}
this.ServeJSON()
} else {
fmt.Println(fh.Filename)
this.SaveToFile("uploadFile", "static/upload/"+fh.Filename)
this.Data["json"] = &map[string]interface{}{"path": "/static/upload/" + fh.Filename, "succ": true}
this.ServeJSON()
}
}
models下的init主要用来进行数据库初始化：
package models
import (
"net/url"
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql"
)
func init() {
dbhost := beego.AppConfig.String("db.host")
dbport := beego.AppConfig.String("db.port")
dbname := beego.AppConfig.String("db.name")
dbuser := beego.AppConfig.String("db.user")
dbpass := beego.AppConfig.String("db.pass")
timezone := beego.AppConfig.String("db.timezone")
if dbport == "" {
dbport = "3306"
}
dsn := dbuser + ":" + dbpass + "@tcp(" + dbhost + ":" + dbport + ")/" + dbname + "?charset=utf8"
if timezone != "" {
dsn = dsn + "&loc=" + url.QueryEscape(timezone)
}
orm.RegisterDataBase("default", "mysql", dsn, 5, 30)
if beego.AppConfig.String("runmode") == "dev" {
orm.Debug = true
}
}
user models，user类的增删改查具体实现封装：
package models

"time"
"github.com/astaxie/beego/orm"

}
qs.Limit(pageSize, offset).OrderBy("-Id").All(&userlist)
count, _ = qs.Count()
return userlist, count
}
func DelUser(idstr string) error {

user.Remark = u.Remark
user.Regtime = strconv.FormatInt(time.Now().Unix(), 10) //获取当前时间戳
id, err := o.Insert(user)
return id, err
}
func UpdateUser(u *User) (int64, error) {
if err := checkUser(u); err != nil {
return 0, err
}
o := orm.NewOrm()
user := make(orm.Params)
if len(u.Name) > 0 {
user["Name"] = u.Name
}
if len(u.Phone) > 0 {
user["Phone"] = u.Phone
}
if len(u.Addr) > 0 {
user["Addr"] = u.Addr
}
if len(u.Email) > 0 {
user["Email"] = u.Email
}
if len(u.Birth) > 0 {
tm, _ := time.Parse("2006-02-02", u.Birth) //日期字符串转为时间戳
user["Birth"] = strconv.FormatInt(tm.Unix(), 10)
}
if len(u.Image) > 0 {

}
if len(u.Remark) > 0 {

}
if len(user) == 0 {

}
var table User
num, err := o.QueryTable(table).Filter("Id", u.Id).Update(user)
return num, err
}
func GetUserByUsername(username string) (user User) {
