以下测试以上面这段JSON作为参考进行测试。
第三方JAR包：（阿里巴巴）fastjson-1.2.5.jar （谷歌）gson-2.2.4.jar
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import com.alibaba.fastjson.JSON;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken; public class MainActivity extends Activity {
public final String TAG = "MainActivity"; Gson my_gson = new Gson();
java.lang.reflect.Type my_type = new TypeToken<TestBean1>() {
}.getType(); @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); new Thread(new Runnable() {
@Override
public void run() {
doSth();
}
}).start();
} private void doSth() {
Log.i(TAG, "start...");
try {
long startTime2 = System.currentTimeMillis();
String json = LocalFileUtils.getStringFormAsset(this, "testbean1.json");
for(int n = 0;n < 100000; n++) {
TestBean1 toBean = JSON.parseObject(json, TestBean1.class);
System.out.println(toBean);
}
long endTime2 = System.currentTimeMillis() - startTime2;
Log.i(TAG, "fastjson....." + endTime2); long startTime4 = System.currentTimeMillis();
String my_json = LocalFileUtils.getStringFormAsset(this, "testbean1.json");
for (int n = 0; n < 100000; n++) {
// 使用JSON 操作 工具将JSON字符串封装到实体类
TestBean1 toBean = my_gson.fromJson(my_json, my_type);
System.out.println(toBean);
}
long endTime4 = System.currentTimeMillis() - startTime4;
Log.i(TAG, "gson....." + endTime4); } catch (Exception e) {
e.printStackTrace();
}
} }
public class TestBean1 {
public String testStr;
public Integer testInt;
public List<NewsItem> data;
public List<Integer> extend;
public int retcode;
public class NewsItem {
public List<NewsCategory> children;
public int id;
public String title;
public int type;
public String url;
public String url1;
public String dayurl;
public String excurl;
public String weekurl;
public class NewsCategory {
public int id;
public String title;
public int type;
public String url;
}
}
}
运行结果：
gson.....122298
fastjson.....138429
