how to read CSV file with apache-spark spring boot

I'm new to Apache Spark and am attempting to use Java Spring Boot to read a CSV file from Apache Spark. however, I kept getting the below exception despite trying several different approaches.

Is there a need for additional configuration?

SparkSession spark = SparkSession
                .builder()
                .appName("Java Spark SQL Example")
                .getOrCreate();
    
    
    StructType schema = new StructType()
            .add("department", "string")
            .add("designation", "string")
            .add("ctc", "long")
            .add("state", "string");
    
    
    Dataset<Row> df = spark.read()
            .option("mode", "DROPMALFORMED")
            .schema(schema)
            .csv("C://exampl/bands-csv.csv");
