Functions ¶
func AddInitializingBean ¶
func AddInitializingBean(handler InitializingBeanHandler)
AddInitializingBean 注册完成回调接口， 执行check成功后会调用回调接口
func AddInitializingBeanFunc ¶
func AddInitializingBeanFunc(handler func())
AddInitializingBeanFunc 注册完成回调方法， 执行check成功后会调用回调方法
func Autowired ¶
func Autowired(is ...interface{})
AutowiredManager 声明需要注入的接口变量 如果目标接口还没有注入实例，会在注入后给将接口实例赋值给指针 如果目标接口类型已经被注入，会立刻获得有效的接口实例
Example ¶
package main
import (
"log"
)
type NameInterface interface {
DO()
}
type TestImpl struct {
name string
}
func (t *TestImpl) DO() {
log.Println("do by:", t.name)
}
func init() {
var nameInterface NameInterface
// 这里一定要要用指针
Autowired(&nameInterface)
AddInitializingBeanFunc(func() {
log.Println("auto wired done")
nameInterface.DO()
})
}
func main() {
t := &TestImpl{name: "demo bean"}
// 转换成注入目标的类型
var i NameInterface = t
// 这里也要用指针，否则反射识别类型会出问题
Injection(&i)
// 检查是否有缺失
err := Check()
if err != nil {
panic(err)
}
}
func GetListByName ¶
func GetListByName(namespaces ...string) []interface{}
func InjectionDefault ¶
func InjectionDefault(i interface{})
InjectionDefault 注入一个构造好的默认实例 * 如果注入多个相同接口类型，后注入的实例会覆盖先注入的实例，default实例不会覆盖普通实例
func RegisterByName ¶
func RegisterByName(namespace string, m interface{})
Types ¶
type Container ¶
type Container interface {
Autowired(p interface{})
Injection(i interface{})
InjectionDefault(i interface{})
Check() error
AddInitializingBean(handler InitializingBeanHandler)
AddInitializingBeanFunc(handler func())
}
Container bean 容器接口
type InitializingBeanHandler ¶
type InitializingBeanHandler interface {
AfterPropertiesSet()
}
InitializingBeanHandler 注入完成后的回调
