----------------------------------

             Summary: "Values not bound to statement" when using JDBC appender 
                 Key: LOG4J2-2667
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2667
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders, Core
    Affects Versions: 2.12.0, 2.11.2
         Environment: Oracle Java 11.0.3

Windows Server 2016

Spring Boot 2.1.6
            Reporter: Edith Chui
             Fix For: 2.12.0, 2.11.2


 

Since version 2.11.2, the log4j2 library was unable to log message on database via JDBC connection. While using 2.11.1, no such problem was found. 

root cause: 

In org.sqlite.core.CorePreparedStatement, below function was called, but paramValid local variable is not initialized. Value of "paramValid.cardinality()" is always 0 which does not match with the total number of parameter.

protected void checkParameters() throws SQLException {
 if (paramValid.cardinality() != paramCount)
 throw new SQLException("Values not bound to statement");
 }

 

Sample appender in log4j2.xml

<JDBC name="jdbcAppender" tableName="LOG_TABLE" bufferSize="0">
<ConnectionFactory class="MY.SQLiteConnectionFactory" method="getDatabaseConnection" />
<ColumnMapping name="FIELD1" type="java.lang.Integer" pattern="%X\{FIELD1}" />
<ColumnMapping name="FIELD2" type="java.lang.String" pattern="%X\{FIELD2}" />
<ColumnMapping name="FIELD3" type="java.lang.String" pattern="%X\{FIELD3}" />
<ColumnMapping name="FIELD4" type="java.sql.Types.TIMESTAMP" pattern="%d\{yyyy-MM-dd HH:mm:ss.SSS}" />
</JDBC>
