Boot4go

a framework to start a web application quickly like as spring-boot

INTRO

Boot4go helps you to create production-grade applications and services with absolute minimum fuss. It takes an opinionated view of the Spring platform so that new and existing users can quickly get to the bits they need.

You can use Boot4go to create stand-alone applications that can be started.

Our primary goals are:

• Provide a radically faster and widely accessible getting started experience for all Spring development.

• Be opinionated, but get out of the way quickly as requirements start to diverge from the defaults.

• Provide a range of non-functional features common to large classes of projects (for example, embedded servers, security, metrics, health checks, externalized configuration).

• Absolutely no code generation and no requirement for XML configuration.

Installation and Getting Started

• Import

import (
	"fmt"
	"github.com/gohutool/log4go"
	"github.com/gohutool/boot4go"
)

The reference documentation includes detailed installation instructions as well as a comprehensive getting started guide.

Code example:

• Autoconfiguration

apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
  name: mysql-snapshot
  version: v1.0.1
  major: 1
tag:
  hello: TAG-HELLO-A
  hello2: TAG-HELLO-B
spec:
  privileged: false
  allowPrivilegeEscalation: false
  volumes:
    - "*"
    - "*.json"
  hostNetwork: false
  hostIPC: false
  hostPID: false
  runAsUser:
    rule1: RunAsAny1
    rule2: RunAsAny2
    rule3: RunAsAny3
  seLinux:
    rule: RunAsAny
  supplementalGroups:
    rule: RunAsAny
  fsGroup:
    rule: RunAsAny

• Test struct

Sample code will autowire test struct, it will autofill the properties using the yaml's configuration

type Test struct {
	age     int16          `bootable:"${metadata.major}"`
	name    string         `bootable:"${metadata.name}"`
	version string         `bootable:"${metadata.version}"`
	data    map[string]any `bootable:"${spec.runAsUser}"`
	list    []any          `bootable:"${spec.volumes}"`
}

• Test autowired properties with expression string

func TestContextConfiguration(t *testing.T) {
	logger := log4go.LoggerManager.GetLogger("test")
	
	logger.Info("YAML %v", ConfigurationContext.ToMap())

	logger.Info("YAML %v", ConfigurationContext.GetValue("${metadata.name}"))
	logger.Info("YAML %v", ConfigurationContext.GetValue("${spec.volumes[0]}"))

	time.Sleep(10 * time.Second)
}
