logback-spring.xml中<property name="log.path" value="./mrm_logs" />的value来自yml

你好！对于这个问题，您可以在yml配置文件中设置一个属性，然后将该属性的值传递给logback-spring.xml中的<property>元素的value属性。具体步骤如下：

1. 在您的application.yml或application.properties文件中添加一个属性，例如：

myapp:
  log:
    path: ./mrm_logs

2. 在logback-spring.xml中，使用`${}`语法引用该属性的值，如下所示：

<configuration>
  <property name="log.path" value="${myapp.log.path}" />
  ...
</configuration>

这样，logback-spring.xml中的log.path属性的值将会从yml配置文件中获取，并且可以动态地根据需要进行更改。
