JNI 实例， 可以作为模板供初学者学习， 例子很详细

package com.ostrichmyself.jni; public class Main { /** * @param args */ static{ System.loadLibrary("BasicJNI"); } public static void main(String[] args) { arrayTest(); } public static void basicDLL() { BasicJNI bs = new BasicJNI(); System.out.println(bs.getBoolean(true)); System.out.println(bs.getDouble(1.15d)); System.out.println(bs.getInt(1)); System.out.println(bs.getString("helloworld ha")); } public static void arrayTest() { JNIArray ja = new JNIArray(); Structure[] structures = new Structure[]{new Structure("a1", 1111), new Structure("a2", 222)}; structures = ja.processsStructures(structures); for (int i = 0; i < structures.length; i++) { System.out.println(structures[i].nameString); } } public static void objectTest() { JNIObject joJniObject = new JNIObject(); String string = joJniObject.processString("abc"); System.out.println(string); Structure structure = joJniObject.processObject(new Structure("aa", 12)); System.out.println(structure.number); } public static void testDll() { JNI jni = new JNI(); System.out.println(jni.getInt()); System.out.println(jni.getString()); System.out.println(); String[] stringArr = jni.getStringArr(); for (int i = 0; i < stringArr.length; i++) { System.out.print(stringArr[i] + " "); } System.out.println(); Structure structure = jni.getStructure(); System.out.println(structure.nameString); System.out.println(structure.number); } }
