发现问题是由于这行代码的参数为null，但这里有两个参数，经过查询代码发现是第二个参数为null，原因是我通过PropertiesUtil类对其外部配置的文件进行获取，但在外部配置的文件中并没有pageSize这个属性，因此发生了报错。解决方法：在外部的properties设置其pageSize的值即可！当pageSize的值设置为2时，页面显示两条记录。当pageSize的值设置为5时，页面显示五条记录。

HTTP Status 500 - Request processing failed; nested exception is java.lang.NumberFormatException: For input string: "null"

HTTP Status 500是一种服务器错误状态码，表示服务器在处理请求时发生了内部错误。"Request processing failed; nested exception is java.lang.NumberFormatException: For input string: "null""是一个具体的错误信息，表明在处理请求时发生了一个NumberFormatException异常，该异常是由于将一个无效的字符串转换为数字时引发的。 NumberFormatException异常通常发生在将字符串转换为数字的过程中，当字符串无法被正确解析为数字时就会抛出该异常。在这个具体的错误信息中，字符串"null"无法被解析为数字，因此引发了NumberFormatException异常。 可能的原因是在请求中传递了一个值为"null"的字符串，而在处理过程中期望得到一个有效的数字。要解决这个问题，你可以检查请求中传递的参数是否正确，并确保传递的值可以正确地转换为数字。
