java中Web Project中加载dll文件的终极解决方案

package com.anllin.jni;

public class TestDLL
{
public TestDLL(String... filenames)
{
// 取得src下的物理路径，
String path = TestDLL.class.getResource("/").getPath();
// 将路径里的%20替换成空格，不然在src目录下会找不到dll文件
path = path.replaceAll("%20", " ");
//output : /D:/myEclispe8.6 projects/jnitest/WebRoot/WEB-INF/classes/
System.out.println(path);
//注：使用System.load()时，文件名必须包含.dll后缀，如test1.dll
for (String filename : filenames)
{
System.load(path + filename);
}
}

public native void test1();

public native void test2();

public native void test3();
}

package com.anllin.jni;

public class TestInvoker
{
private TestDLL testDll;

public TestInvoker()
{
// 注意，一定要确定DLL之间的依赖关系，谁先加载，谁后加载，不然会报错，先加载的放在前面
　　　　 testDll = new TestDLL("test1.dll", "test2.dll", "test3.dll");
}

public void test1()
{
testDll.test1();
}

public void test2()
{
testDll.test2();
}

public void test3()
{
testDll.test3();
}
}
