go-spring's Introduction

Go-Spring 的愿景是让 Go 程序员也能用上如 Java Spring 那般威力强大的编程框架。

其特性如下:

  1. 提供了完善的 IoC 容器,支持依赖注入、属性绑定;
  2. 提供了强大的启动器框架,支持自动装配、开箱即用;
  3. 提供了常见组件的抽象层,支持灵活地替换底层实现;

Go-Spring 当前使用 Go1.12 进行开发,使用 Go Modules 进行依赖管理。

IoC 容器

Go-Spring 不仅实现了如 Java Spring 那般功能强大的 IoC 容器,还扩充了 Bean 的概念。在 Go 中,对象(即指针)、数组、Map、函数指针,这些都是 Bean,都可以放到 IoC 容器里。

常用的 Java Spring 注解 对应的 Go-Spring 实现
@Value value:"${}"
@Autowired @Qualifier @Required autowire:"?"
@Configurable WireBean()
@Profile ConditionOnProfile()
@Primary Primary()
@DependsOn DependsOn()
@ConstructorBinding RegisterBeanFn()
@ComponentScan @Indexed Package Import
@Conditional NewConditional()
@ConditionalOnExpression NewExpressionCondition()
@ConditionalOnProperty NewPropertyValueCondition()
@ConditionalOnBean NewBeanCondition()
@ConditionalOnMissingBean NewMissingBeanCondition()
@ConditionalOnClass Don't Need
@ConditionalOnMissingClass Don't Need
@Lookup ——

属性绑定

Go-Spring 不仅支持对普通数据类型进行属性绑定,也支持对自定义值类型进行属性绑定,而且还支持对结构体属性的嵌套绑定。

type DB struct {
	UserName string `value:"${username}"`
	Password string `value:"${password}"`
	Url      string `value:"${url}"`
	Port     string `value:"${port}"`
	DB       string `value:"${db}"`
}

type DbConfig struct {
	DB []DB `value:"${db}"`
}

上面这段代码可以通过下面的配置进行绑定:

db:
  -
    username: root
    password: 123456
    url: 1.1.1.1
    port: 3306
    db: db1
  -
    username: root
    password: 123456
    url: 1.1.1.1
    port: 3306
    db: db2

Boot 框架

Go-Spring 提供了一个功能强大的启动器框架,不仅实现了自动加载、开箱即用,而且可以非常容易的开发自己的启动器模块,使得代码不仅仅是库层面的复用。

快速示例

下面的示例使用 v1.0.5 版本测试通过。

import (
	"context"

	"github.com/go-spring/spring-boot"
	_ "github.com/go-spring/starter-echo"
)

func init() {
	SpringBoot.RegisterBean(new(Service)).Init(func(s *Service) {
		SpringBoot.GetBinding("/", s.Echo)
	})
}

type Service struct {
	GoPath string `value:"${GOPATH}"`
}

type EchoRequest struct{}

func (s *Service) Echo(ctx context.Context, req *EchoRequest) interface{} {
	return s.GoPath
}

func main() {
	SpringBoot.RunApplication()
}

启动上面的程序,控制台输入 curl http://localhost:8080/, 可得到如下结果:

{"code":200,"msg":"SUCCESS","data":"/Users/didi/go"}
