Versi Springboot ialah 1.3.5
versi log balik ialah 1.1.7

Answer 1

Tomcat7.0 naik taraf kepada 8.0 penyelesaian masalah

Answer 2

Bolehkah saya berperang secara tempatan?

Answer 3

Sebab: Hubungan antara ClassLoader, pelaksanaan ClassLoader dalam IDE adalah berbeza daripada Spring Boot JarLauncher, oleh itu, balang yang berbeza dimuatkan. log4j-slf4j dan logback ialah kedua-dua pelaksanaan slf4j-api, jadi ia bercanggah.

Penyelesaian: Alih keluar pergantungan log4j-slf4j (melalui Maven)
