Development environment: windows. Please be sure to do this operation in the windows operating system, because word needs to be converted to pdf on the server.
Please install word on your computer, pay attention to installing word, not wps (this is very important).
Please install the word to pdf plug-in on your computer: "Software name: SaveAsPDFandXPS", download address: http://download.csdn.net/download/tiandixuanwuliang/10006993
Please put the dll file that the system needs to call in the bin directory of jre in the java environment, for example: C:\Program Files\Java\jdk1.7.0_13\bin\jacob-1.18-x64.dll, (please pay attention to your computer 32 Bit or 64 bit) download address: http://download.csdn.net/download/tiandixuanwuliang/10007003
Put jacob.jar in the C:\Windows\System32 directory. At the same time, it is introduced into the project file.
The usage in the project is as follows:
