This worked for me with log4j2 and xml parameters:

    
        /some_path/logs/
        my_app
    

    
        
            
                [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
                
            
            
                
            
        

        
            
        
    
    

        
            
            
        

        
            
            
        
    

Result console and file log was:

JdbcTemplate - Executing prepared SQL query
JdbcTemplate - Executing prepared SQL statement [select a, b from c where id = ? ]
StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [my_id], value class [java.lang.String], SQL type unknown

Just copy/past
