DI, IoC container
A library for creating objects and managing their dependencies. This library can be used for managing dependencies in a unified way, managing global objects, and refreshing dynamic configurations.
go get github.com/mix-go/xdi
Create a singleton through dependency configuration
package main
import (
"github.com/mix-go/xdi"
)
type Foo struct {
}
func init() {
obj := &xdi.Object{
Name: "foo",
New: func() (interface{}, error) {
i := &Foo{}
return i, nil
},
}
if err := xdi.Provide(obj); err != nil {
panic(err)
}
}
func main() {
var foo *Foo
if err := xdi.Populate("foo", &foo); err != nil {
panic(err)
}
// use foo
}Refer to another dependency configuration instance in the dependency configuration
package main
import (
"github.com/mix-go/xdi"
)
type Foo struct {
Bar *Bar
}
type Bar struct {
}
func init() {
objs := []*xdi.Object{
{
Name: "foo",
New: func() (interface{}, error) {
// reference bar
var bar *Bar
if err := xdi.Populate("bar", &bar); err != nil {
return nil, err
}
i := &Foo{
Bar: bar,
}
return i, nil
},
},
{
Name: "bar",
New: func() (interface{}, error) {
i := &Bar{}
return i, nil
},
NewEverytime: true,
},
}
if err := xdi.Provide(objs...); err != nil {
panic(err)
}
}
func main() {
var foo *Foo
if err := xdi.Populate("foo", &foo); err != nil {
panic(err)
}
// use foo
}When the configuration information changes during program execution, Refresh() can refresh the singleton instance to switch to using the new configuration. It is commonly used in microservice configuration centers.
obj, err := xdi.DefaultContainer.Object("foo")
if err != nil {
panic(err)
}
if err := obj.Refresh(); err != nil {
panic(err)
