First, let’s talk about Chinese garbled characters Problem, javapdf uses ISO-8859-1 encoding internally, and usually our database encoding is UTF-8 or GBK. If transcoding is not performed before javapdf is written, the exported file will be garbled in Chinese, so after traversing each This code should be added to the data of each field

 if(object instanceof String){  
         object = new String(((String)object).getBytes("GBK"),"ISO-8859-1");  
}

The GBK here is the encoding of the database where the data is located, which changes according to your own situation.

Let’s talk about data misalignment, because the maximum field length supported by PDF is only 255, so when the field length you pass in is greater than 255, javapdf will perform a %6 operation with you to ensure that the field length is less than 256 , and data misalignment is usually caused by this operation, so we can only control the length of the incoming field data on the code side and intercept it appropriately to ensure that the length of the field you transfer cannot be greater than 255, while ensuring that your field data It will not be greater than 255, and Chinese must be divided by 2.
