初始化logback之前的spring JNDI日志记录

Question

我有一个弹簧启动应用程序,在初始化logback之前,在启动时输出大约1500行JNDI调试日志记录到stdout.有谁知道造成这种情况的原因以及是否有办法在此之前初始化后退？我有-Dlogback.debug = true但它没有多大帮助.

使用自定义logback-spring.xml时,我也看到了Spring Boot 1.5.1.如果logback-spring.xml不存在,则不会出现调试语句.

我能够通过禁用JNDIPropertySource解决它.在类路径根目录中创建一个文件spring.properties:

# Disable the JNDIPropertySource. This avoids dozens of spurious DEBUG messages
# when starting up with a custom logback-spring.xml. We're not alone:
# http://stackoverflow.com/questions/42446013/spring-jndi-logging-before-logback-is-initialized
spring.jndi.ignore=true

spring.jndi.ignore已添加到https://jira.spring.io/browse/SPR-14026.

这种方法感觉很乱,但是因为我没有在JNDI有用的容器中运行,所以它不会破坏我的任何东西.
