基于itextpdf的java读取和更新pdf表单域字段值功能
执行结果为:
Hello World!
key=topmostSubform[0].Page1[0].qhjc[0]
key=topmostSubform[0].Page1[0].qhmc[0]
key=topmostSubform[0].Page1[0].cqzh[0]
key=topmostSubform[0].Page1[0].fm_year[0]
key=topmostSubform[0].Page1[0].nd[0]
key=topmostSubform[0].Page1[0].fm_day[0]
key=topmostSubform[0].Page1[0].fj[0]
key=topmostSubform[0].Page1[0].qt[0]
