Bagaimana untuk menyimpan log konsol dalam projek SpringBoot-javaTutorial-php.cn

Konfigurasi penjimatan log konsol SpringBoot

Senario: Log konsol perlu disimpan dalam projek SpringBoot.

Kaedah pelaksanaan:

1. Konfigurasikan fail konfigurasi application-prod.yml

seperti berikut:

logging:
  config: classpath:logback-spring-prod.xml

Salin selepas log masuk

2.logback-spring-prod. xml

Fail ini ialah laluan untuk menyimpan log cetakan konsol Konfigurasi adalah seperti berikut:

Bagaimanakah projek SpringBoot menyimpan log masa jalan perkhidmatan?

Masalah ini agak mudah Anda hanya perlu melengkapkan dua langkah

Konfigurasikan fail log keluaran log4j

Anda perlu memetik kebergantungan lombok dalam pom, dan versi boleh mengikut versi springboot anda

Fail log keluaran Log4j, letakkan sahaja di bawah sumber Perhatikan bahawa perkara dalam fileNamePattern tag digantikan dengan logo Fungsi perkhidmatan mikro anda, seperti sistem pengurusan pelajar yang saya tulis, jadi saya menggunakan pelajar

Nyatakan lokasi fail konfigurasi ini dalam aplikasi

logging:
  level:
    com.netflix.discovery.shared.resolver.aws.ConfigClusterResolver: WARN
