64位的程序是不能加载32位的库，32位的库和64位应用程序是不兼容的。 所以如果在load过程中发现出错，首先得确定所加载的库是64的。如何判断库是64位的？dumpbin.exe 它用来分析二进制库和程序的结构。在应用程序中找到 VS2010 -> VS tools -> VS x64 Win64 Command Prompt 执行dumpbin命令。下面分别为32位和64位库的不同。 32bit DLL C:\Program Files (x86)\Java50\jre\bin\j9vm>dumpbin /headers jvm.dll Microsoft (R) COFF/PE Dumper Version 10.00.30319.01 Copyright (C) Microsoft Corporation.
