java解析xml

在这段代码中~~~~我解析的是海词提供的xml~~~~~~~~~~~~~运行环境是Eclipse~~~~~~~~~~不过在编码部分还存在一定的问题~~~~~~~~~有待努力~~~~~~~继续提高~~~~~~~~~~嘿嘿~~~~~~~~~~~~~~~

[转]在Java中调用C语言生成的DLL文件

一、JAVA中所需要做的工作

在JAVA程序中，首先需要在类中声明所调用的库名称，如下：

static {

System.loadLibrary(“goodluck”);

}

在这里，库的扩展名字可以不用写出来，究竟是DLL还是SO，由系统自己判断。

还需要对将要调用的方法做本地声明，关键字为native。并且只需要声明，而不需要具体实现。如下：

public native static void set(int i);

public native static int get();

然后编译该JAVA程序文件，生成CLASS，再用JAVAH命令，JNI就会生成C/C++的头文件。

例如程序testdll.java，内容为：

public class testdll

{

static

{

System.loadLibrary("goodluck");

}

public native static int get();

public native static void set(int i);

public static void main(String[] args)

{

testdll test = new testdll();

test.set(10);

System.out.println(test.get());

}

}

用javac testdll.java编译它，会生成testdll.class。

再用javah testdll，则会在当前目录下生成testdll.h文件，这个文件需要被C/C++程序调用来生成所需的库文件。

二、C/C++中所需要做的工作

对于已生成的.h头文件，C/C++所需要做的，就是把它的各个方法具体的实现。然后编译连接成库文件即可。再把库文件拷贝到JAVA程序的路径下面，就可以用JAVA调用C/C++所实现的功能了。

接上例子。我们先看一下testdll.h文件的内容：

/* DO NOT EDIT THIS FILE - it is machine generated */

#include

/* Header for class testdll */

#ifndef _Included_testdll

#define _Included_testdll

#ifdef __cplusplus

extern "C" {

#endif

/*

* Class: testdll

* Method: get

* Signature: ()I

*/

JNIEXPORT jint JNICALL Java_testdll_get

(JNIEnv *, jclass);

/*

* Class: testdll

* Method: set

* Signature: (I)V

*/

JNIEXPORT void JNICALL Java_testdll_set

(JNIEnv *, jclass, jint);

#ifdef __cplusplus

}

#endif

#endif

在具体实现的时候，我们只关心两个函数原型

JNIEXPORT jint JNICALL Java_testdll_get (JNIEnv *, jclass);

和

JNIEXPORT void JNICALL Java_testdll_set (JNIEnv *, jclass, jint);

这里JNIEXPORT和JNICALL都是JNI的关键字，表示此函数是要被JNI调用 的。而jint是以JNI为中介使JAVA的int类型与本地的int沟通的一种类型，我们可以视而不见，就当做int使用。函数的名称是JAVA_再加 上java程序的package路径再加函数名组成的。参数中，我们也只需要关心在JAVA程序中存在的参数，至于JNIEnv*和jclass我们一般没有必要去碰它。

好，下面我们用testdll.cpp文件具体实现这两个函数：

#include "testdll.h"

int i = 0;

JNIEXPORT jint JNICALL Java_testdll_get (JNIEnv *, jclass)

{

return i;

}

JNIEXPORT void JNICALL Java_testdll_set (JNIEnv *, jclass, jint j)

{

i = j;

}

编译连接成库文件，本例是在WINDOWS下做的，生成的是DLL文件。并且名称要与JAVA中需要调用的一致，这里就是goodluck.dll

把goodluck.dll拷贝到testdll.class的目录下，java testdll运行它，就可以观察到结果了。
