### Demo3 获取好友头像图片示例

代码自释吧，需要注意的是需要自己设定保存头像文件的路径，收到`111`消息后，将会下载所有好友的头像。

```java
package cn.zhouyafeng.itchat4j.demo.demo3;

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.List;

public class PicYourFriends implements IMsgHandlerFace {
private static Logger LOG = LoggerFactory.getLogger(PicYourFriends.class);
private static final Core core = Core.getInstance();
private static final MyHttpClient myHttpClient = core.getMyHttpClient();
private static final String path = "D://itchat4j//head"; // 这里需要设置保存头像的路径

@Override
public String textMsgHandle(JSONObject msg) {

if (!msg.getBoolean("groupMsg")) { // 群消息不处理

// String fileName = friend.getString("NickName");
String headPicPath = path + File.separator + i + ".jpg";

try {
OutputStream out = new FileOutputStream(headPicPath);
byte[] bytes = EntityUtils.toByteArray(entity);
out.write(bytes);
out.flush();
out.close();

} catch (Exception e) {
LOG.info(e.getMessage());

@Override
public String nameCardMsgHandle(JSONObject msg) {

return null;
}

public static void main(String[] args) {
String qrPath = "D://itchat4j//login"; // 保存登陆二维码图片的路径，这里需要在本地新建目录
IMsgHandlerFace msgHandler = new PicYourFriends(); // 实现IMsgHandlerFace接口的类
Wechat wechat = new Wechat(msgHandler, qrPath); // 【注入】
wechat.start(); // 启动服务，会在qrPath下生成一张二维码图片，扫描即可登陆，注意，二维码图片如果超过一定时间未扫描会过期，过期时会自动更新，所以你可能需要重新打开图片
}

}

### Demo3 itchat4j集成在SpringMVC应用中


### itchat4j集成在SpringMVC应用中

若需要将itchat4j集成在自己的应用中，打开项目pom.xml文件所在目录，运行`mvn package`，将生成的itchat4j的jar包引入即可。

这个示例要讲起来就比较困难了，因为SpringMVC本身就是一个复杂的东西，先在这里挖个坑吧。其实在SpringMVC中集成与上面两个示例并没有太大的不同，我的个人博客是基于SpringMVC的，我已经将集成在这个项目里了，这样我就可以通过微信来更新我的博客了。详细的就不多说了，大家先看看这个项目结构吧。
