日志

用户自定义日志管理。

概念

日志默认会打印到 stdout.

安装

$ go get github.com/rookie-ninja/rk-boot/v2
$ go get github.com/rookie-ninja/rk-gin/v2
$ go get github.com/rookie-ninja/rk-db/mysql

日志 level

日志级别默认为 warn。

支持的日志级别:

• info
• warn
• error
• silent

1.创建 boot.yaml

---
gin:
  - name: user-service
    port: 8080
    enabled: true
mysql:
  - name: demo-db
    enabled: true
    addr: "localhost:3306"
    logger:
      level: info             # Set log level to info
    database:
      - name: demo
        autoCreate: true

2.创建 main.go

package main

import (
    "context"
    "github.com/rookie-ninja/rk-boot/v2"
    "github.com/rookie-ninja/rk-db/mysql"
    _ "github.com/rookie-ninja/rk-db/mysql"
    "gorm.io/gorm"
    "time"
)

func main() {
    boot := rkboot.NewBoot()

    boot.Bootstrap(context.TODO())

    // Auto migrate database and init global userDb variable
    mysqlEntry := rkmysql.GetMySqlEntry("demo-db")
    userDb := mysqlEntry.GetDB("demo")

    if !userDb.DryRun {
        userDb.AutoMigrate(&User{})
    }

    boot.WaitForShutdownSig(context.TODO())
}

// *************************************
// *************** Model ***************
// *************************************

type Base struct {
    CreatedAt time.Time      `yaml:"-" json:"-"`
    UpdatedAt time.Time      `yaml:"-" json:"-"`
    DeletedAt gorm.DeletedAt `yaml:"-" json:"-" gorm:"index"`
}

type User struct {
    Base
    Id   int    `yaml:"id" json:"id" gorm:"primaryKey"`
    Name string `yaml:"name" json:"name"`
}

输出

...
2022-09-19T00:42:46.790+0800    INFO    mysql@v1.3.6/migrator.go:250    [1.337ms] [rows:-] SELECT DATABASE()
2022-09-19T00:42:46.794+0800    INFO    mysql@v1.3.6/migrator.go:253    [3.696ms] [rows:1] SELECT SCHEMA_NAME from Information_schema.SCHEMATA where SCHEMA_NAME LIKE 'demo%' ORDER BY SCHEMA_NAME='demo' DESC,SCHEMA_NAME limit 1
...

日志路径

1.创建 boot.yaml

---
gin:
  - name: user-service
    port: 8080
    enabled: true
mysql:
  - name: demo-db
    enabled: true
    addr: "localhost:3306"
    logger:
      level: info
      outputPaths: [ "log/db.log" ]

2.验证

.
├── boot.yaml
├── go.mod
├── go.sum
├── log
│   └── db.log
└── main.go

所有选项

mysql:
  - name: demo-db                               # Required
    enabled: true                               # Required

      encoding: json                            # Optional, default: console, options: [json, console]
      outputPaths: [ "log/db.log" ]             # Optional, default: empty

      ignoreRecordNotFoundError: false          # Optional, default: false
    database:
      - name: demo                              # Required
        plugins:
          prom:
            enabled: false
        autoCreate: true                        # Optional, default: false
        dryRun: false                           # Optional, default: false
        params: []                              # Optional, default: ["charset=utf8mb4","parseTime=True","loc=Local"]
