一、在java中加载ddl文件的方法:
System.load(dllPath); //dllPath为dll文件的绝对路径。 或者
System.loadLibrary(libname); //libname为dll文件名,该dll要放到类路径中。
二、在java中卸载dll文件的方法:
private void unloadNativeLibs() {
try {
ClassLoader classLoader = this.getClass().getClassLoader();
Field field = ClassLoader.class.getDeclaredField("nativeLibraries");
field.setAccessible(true);
Vector libs = (Vector) field.get(classLoader);
Iterator it = libs.iterator();
Object o;
while (it.hasNext()) {
o = it.next();
Method finalize = o.getClass().getDeclaredMethod("finalize", new Class[0]);
finalize.setAccessible(true);
finalize.invoke(o, new Object[0]);
}
} catch (Exception ex) {
log.error("卸载dll文件出错,需要重启服务器!", ex);
throw new RuntimeException(ex);
}
}
