iocgo

An IOC container in Golang

This project is inspired by the IOC-Golang and K8S controller-tools projects

Design ideas

1.BeanDefinition

• bean name

• scope

• autowire enabled

• configuration struct

• factory func

• init func

• destroy func

• description

• // +ioc:autowired:beandefinition  // mark a beandefinition
  
  type DumpyBeanDefinition struct {
  	Name              string      // bean name
  	Scope             scope.Scope // scope of bean
  	AutowireCandidate bool        // autowire enabled
  	Configuration     string      // configuration struct
  	FactoryFunc       string      // factory func
  	InitFunc          string      // init func
  	DestroyFunc       string      // destroy func
  	Description       string      // description of bean
  }
  

2.BeanFactory

• Register
• GetBean
• Destroy

3.LifeCycle

• InitializingBean
  • AfterPropertiesSet()
• DisposableBean
  • Destroy()

4.Configuration

// +ioc:autowired:factorybean // mark a bean is a factory bean

type Person struct {
ID   int64  `json:"id"`
Name string `json:"name"`
Age  uint8  `json:"age"`
}

// +ioc:autowired:configuration // mark a configuration struct -> @Configuration
type PersonConfiguration struct {
}

// +ioc:autowired:factoryfunc // mark a func is configuration factory func -> @Bean
// +ioc:autowired:scope=singleton // mark a bean scope is singleton

func (config *PersonConfiguration) CreatePerson(ctx context.Context) Person {
return Person{
ID:   9527,
Name: "photowey",
Age:  18,
}
}
