springboot 如何将一个list写入到csv文件中呢？

实现思路:
    1.引入相应的jar包
	2.编写相应的工具类
	  遍历写入数据到csv文件中

1.引入依赖jar
 <dependency>
     <groupId>net.sourceforge.javacsv</groupId>
     <artifactId>javacsv</artifactId>
     <version>2.0</version>
 </dependency>

2.工具类
public class CsvFileUtils {
   /**
     * 写方法
     * @param dataset  写入内容list
     * @param csvFilePath 保存路径
     * @param csvHeaders  csv文件表头
     * @param <T>
     */
    public static <T> void writeCSV(Collection<T> dataset, String csvFilePath, String[] csvHeaders) {
        try {
            // 定义路径，分隔符，编码
            CsvWriter csvWriter = new CsvWriter(csvFilePath, ',', Charset.forName("GBK"));
            // 写入表头
            csvWriter.writeRecord(csvHeaders);
            // 将list 组装成字符串类型数据
            Iterator<T> it = dataset.iterator();
            while (it.hasNext()) {
                T t = (T) it.next();
                //获取类属性
                Field[] fields = t.getClass().getDeclaredFields();
                String[] csvContent = new String[fields.length];
                for (short i = 0; i < fields.length; i++) {
 
 
                    Field field = fields[i];
                    String fieldName = field.getName();
                    String getMethodName = "get"
                            + fieldName.substring(0, 1).toUpperCase()
                            + fieldName.substring(1);
                    try {
                        Class tCls = t.getClass();
                        Method getMethod = tCls.getMethod(getMethodName, new Class[]{});
                        Object value = getMethod.invoke(t, new Object[]{});
                        if (value == null) {
                            continue;
                        }
                        //取值并赋给数组
                        String textvalue = value.toString();
                        csvContent[i] = textvalue;
                    } catch (Exception e) {
                        e.getStackTrace();
                    }
                }
                //迭代插入记录
                csvWriter.writeRecord(csvContent);
            }
            csvWriter.close();
            System.out.println("<--------CSV文件写入成功-------->");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

  public static void main(String[] args) {
        String[] csvHeaders = {"name", "age"};
        String csvFilePath = "d:/testInfo.csv";
        List<User> list = new ArrayList<>();
        
        User p = new User();      
        p.setName("java265");
		p.setage(28);
