Background: As usual, we have different life cycles, such as dev. stage, lt, prod they are all selected during deployment from the environment variable $ {lifecycle}. Thus, the JNDI parameter is stored in $ {lifecycle} .properties as the variable datasource.jndi.name = jdbc / xxx. Since other beans also use this properties file, it is verified that such a variable is loaded and the file is in the classpath, but somehow I cannot use this variable in log4j2.xml below the JDBC Appender.
<JDBC name="DBAppender" tableName="V1_QUERY_LOG" bufferSize="4" ignoreExceptions="false">
<DataSource jndiName="${sys:datasource.jndi.name}" />
<Column name="event_date" isUnicode="false" isEventTimestamp="true" />
<Column name="log_level" isUnicode="false" pattern="%level" />
<Column name="logger" isUnicode="false" pattern="%logger" />
<Column name="message" isUnicode="false" pattern="%message" />
<Column name="exception_msg" isUnicode="false" pattern="%ex{full}" />
</JDBC>
I also tried the option "$ {datasource.jndi.name}" or is there a way that I can match the solution in
<Properties>
<Property name="datasource.jndi.name">get datasource.jndi.name from {lifecycle}.properties</property>
</Properties>
