jacob.jar1.19及使用方法
解压后获得3个文件
jacob.jar
jacob-1.17-x64.dll
jacob-1.17-x86.dll
jacob.jar 放到项目的lib目录
win7
jacob-1.17-x64.dll 放到C:\Windows\System32
jacob-1.17-x86.dll 放到C:\Windows\SysWOW64
win7就是这么设计的, System32放64位dll,SysWOW64放32位dll,是不是很诡异。
还要注意的是,32位JDK只能加载32位DLL,64位JDK只能加载64位DLL,不能互相兼容。
还可以把jacob-1.17-x86.dll 放到jdk/jre/bin下,我选的这个
若找不到jacob.dll,会报如下错误
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jacob-1.17-x86 in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)

如果不清楚java.library.path,输出一下即可。代码如下
System.out.println(System.getProperty("java.library.path"));
