This article mainly introduces "how to use golang imitating spring ioc/aop annotation-based static code enhancer / generator". In daily operation, it is believed that many people have doubts about how to use golang imitating spring ioc/aop annotation-based static code enhancer / generator. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful to answer the question of "how to use golang imitating spring ioc/aop annotation-based static code enhancer / generator"! Next, please follow the editor to study!

Hand-play golang spring ioc/aop 2

SpringSpring implements a lightweight Java Web Service system application framework based on J2EE technology. It has many excellent features, and many companies choose Spring as the basic development architecture of their products or projects. Spring features include lightweight, control inversion (Inversion of Control, IoC), container-oriented, aspect-oriented (AspectOriented Programming, AOP) and framework flexibility.

Subgoal (Day 2)

Conceive the mode of operation of app:

Local standlone mode operation

Provide real-time command line interaction based on cli

Generate bypass code: only scan the source code, do not modify the source code, and add a unified suffix to the enhanced code

Design the cli interactive instruction set:

Config save: saving configuration

Config saveas: saving configuration

Watch add: adding code to scan directories

Watch del: remove code scan directory

Watch list: displays the collection of code directories currently scanned

Gen: generate enhancement code, that is, scan all annotations and generate enhancement classes and enhancement methods

Config/IConfiguration.go

Configure Interfac

Package config// IConfiguration defines system configuration interfacetype IConfiguration interface {GetProjectName () string SetProjectName (string) GetWatchPaths () [] string AddWatchPath (string) DelWatchPath (string) Save () error SaveAS (string) error} command/ICmd.go

Instruction interface

Package commandimport "fmt" / / ICmd defines cli command interfacetype ICmd interface {fmt.Stringer / / Apply apply current command into use Apply (ICmdContext) error} command/ICmdBuilder.go

Instruction builder interface

Package command// ICmdBuilder parse input string and create an ICmd instancetype ICmdBuilder interface {Build (string) (error, ICmd)} command/ICmdContext.go

Instruction execution context interface

Package commandimport "learning/gooop/spring/autogen/config" / / ICmdContext provides context info for all commandstype ICmdContext interface {GetConfiguration () config.IConfiguration} config_cmd/SaveCmd.go

Save configuration

Package config_cmdimport ("learning/gooop/spring/autogen/command") / / SaveCmd calls service.Save () to save current configuration In JSON formattype SaveCmd int// SaveCmdBuilder parse cli input and build a SaveCmd instancetype SaveCmdBuilder intconst gSaveCmdString = "config save" var gSaveCmdInstance = new (SaveCmd) func (me * SaveCmd) String () string {return gSaveCmdString} func (me * SaveCmd) Apply (c command.ICmdContext) error {/ / todo: fixme panic ("implements me")} func (me * SaveCmdBuilder) Build (line string) (error, command.ICmd) {if line! = gSaveCmdString {return nil Nil} return nil, gSaveCmdInstance} config_cmd/SaveASCmd.go

Save configuration

Package config_cmdimport ("errors"learning/gooop/spring/autogen/command"strings") / / SaveASCmd calls service.SaveAS () to save current config into specific file In JSON formattype SaveASCmd struct {file string} / / SaveASCmdBuilder parse cli input and returns a SaveASCmd instancetype SaveASCmdBuilder intconst gSaveASCmdPrefix = "config saveas" func (me * SaveASCmd) String () string {return gSaveASCmdPrefix + me.file} func (me * SaveASCmd) Apply (c command.ICmdContext) error {/ / todo: fixme panic ("implements me") func (me * SaveASCmdBuilder) Build (line string) (error, command.ICmd) {if! strings.HasPrefix (line) GSaveASCmdPrefix) {return nil, nil} file: = strings.TrimSpace (line [len (gSaveASCmdPrefix):]) if len (file)
