Java支持读取CSV文件并将其转换为Java Bean对象。这通常可以通过使用第三方库（如OpenCSV）来实现。

首先，需要创建一个Java Bean类，它映射到CSV文件中的每一行数据。然后，可以使用OpenCSV库的API读取CSV文件，将其转换为Java Bean对象的列表。

代码示例：

import java.io.FileReader;
import java.util.List;

import com.opencsv.bean.CsvToBeanBuilder;

public class CSVReader {
    public static void main(String[] args) throws Exception {
        FileReader fileReader = new FileReader("file.csv");

        List<YourJavaBeanClass> beans = new CsvToBeanBuilder(fileReader)
                .withType(YourJavaBeanClass.class)
                .build()
                .parse();

        for (YourJavaBeanClass bean : beans) {
            System.out.println(bean);
        }
    }
}

这是一个使用OpenCSV读取CSV文件并将其转换为Java Bean的简单示例。
