The procedure for utilizing item reader in Spring Batch to interpret outcomes from an mdb file:

1. Create a Spring Batch project and include the required dependencies for reading and processing mdb files.
2. Define a bean for the item reader, which uses the JdbcCursorItemReader provided by Spring Batch to read data from the mdb file.
3. Configure the item reader with the necessary information such as database connection details, SQL query to retrieve data, and mapping of columns to fields in the output.
4. Define a job and a step in the Batch configuration, and use the item reader in the step to read and process data from the mdb file.
5. Optionally, define a processor and a writer to further process the data read by the item reader and to output it to the desired destination.

Here is an example configuration for an item reader that reads data from an mdb file using JdbcCursorItemReader:

@Bean
public JdbcCursorItemReader<Data> itemReader() {
    JdbcCursorItemReader<Data> reader = new JdbcCursorItemReader<>();
    reader.setDataSource(dataSource);
    reader.setSql("SELECT * FROM mytable") // SQL query to retrieve data
    reader.setRowMapper(new BeanPropertyRowMapper<>(Data.class)); // mapping of columns to fields
    return reader;
}

In this example, the Data class is a simple Java bean with properties that correspond to the columns in the mdb file. The item reader uses the BeanPropertyRowMapper provided by Spring Batch to map the columns in the result set to the properties of the Data class.
