ssm project in Chinese characters garbled

　　Yesterday a mistake to change the students in SSM project, String type of form input, the Chinese character values, always garbled, the data controller layer acquisition began garbled, we have carried out the investigation as follows:

web.xml configuration settings listener character encoding (filters),
Jsp page encoding format, use Notepad to open view,
Setting encoding format jsp page

After completion of the investigation, there is no problem, or distortion, and then this morning to ask the teacher. The teacher gave a solution.

After the controller layer obtained data string, the string processing to convert the string to an array of bytes, then the specified string is encoded in the encoding.
