Detailed tutorial on splitting text strings

Question: In the project, when the saved data exceeds the database field column length limit, how to solve it?

A common solution is: string truncation and access. As the name suggests, large text data is intercepted according to the specified length, and the returned result set is stored in a new table in the order of interception. And by creating a type field in the new table to identify that the intercepted content in the new table corresponds to the field name in the old table, the corresponding fields in the old table no longer directly store large text data, but store identifiers.

Here, a tool class is provided to split text strings and return a List result set for the next step.

public class StringUtil {/**  
    * @Name: getContentByList
    * @Description: 字符串切割
    * @Author: 张（作者）
    * @Version: V1.00 （版本号）
    * @Create Date: 2017-6-26（创建日期）
    * @Parameters: wholecontent：传递的文本字符串；
                   cutcount：切割字符串的长度
    * @Return: List：切割字符串形成的集合，存放结果集*/public static List<string> getContentByList(String wholecontent,int cutcount){
        List<string> list = new ArrayList<string>();//获取完整内容字符串的总长度int contentlen = wholecontent.length(); //内容截取，用内容总长和截取长度进行比较，无须截取的话直接插入if (contentlen </string></string></string>
