问题解决：
1.
//error 输入
type (

}
)
// mark 输入
type(
SimpleUserReq struct {
Id int `uri:"id" binding:"required,min=100"`
}
)
error
//GET /users/123
func(this UserController) UserDetail(ctx *gin.Context) goft.Json {
simpleUserReq := &dto.SimpleUserReq{}
ctx.ShouldBindUri(simpleUserReq)
return this.UserSvr.GetSimpleUserInfo(simpleUserReq)
}
mark
//GET /users/123
func(this *UserController) UserDetail(ctx *gin.Context) goft.Json {
simpleUserReq := &dto.SimpleUserReq{}
ctx.ShouldBindUri(simpleUserReq)
return this.UserSvr.GetSimpleUserInfo(simpleUserReq)
}
实现1
func NewUserService() *UserService {
return &UserService{
UserRepo: dao.NewUserRepo(),
}
}
usr := NewUserService()
usr.UserRepo.FindById(userModel)
//this.UserRepo.FindById(userModel)
实现2
func main(){
goft.Ignite().
Config(configs.NewUserServiceConfig(), configs.NewDBConfig(), configs.NewRepoConfig()).
Mount("v1",controllers.NewUserController()).
Launch()
}
type RepoConfig struct {
}
func NewRepoConfig() *RepoConfig {
return &RepoConfig{}
}
func(*RepoConfig) UserRepo() repos.IUserRepo{
return &dao.UserRepo{}
}
type UserService struct {
AssUserReq *assembler.UserReq
AssUserRsp *assembler.UserRsp
UserRepo repos.IUserRepo `inject:"-"`
UserLogRepo repos.IUserLogRepo `inject:"-"`
}
this.UserRepo.FindById(userModel)
总结：
1.大小写的问题
type UserService struct {
AssUserReq *assembler.UserReq
AssUserResp *assembler.UserResp
UserRepos repos.IUserRepos `inject:"-"`
//userRepos repos.IUserRepos `inject:"-"` error 无法被注入
UserLogRepo repos.IUserLogRepos `inject:"-"`
}
2.注入问题
`inject:"-"`
3.库的引入
"gorm.io/gorm"
or 不同
"github.com/jinzhu/gorm"
