我试图在Apache Commons Configuration库的帮助下解析apple的plist文件。当我尝试下面的例子作为Java应用程序一切正常，但Android上的相同代码抛出异常。
好的，有关详细信息，请参阅以下代码：
这是我的Android应用程序的入口点：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
Log.i("AC", "Hello");
XMLPropertyListConfiguration plist = new XMLPropertyListConfiguration();
plist.setFileName("assets/data.plist");
plist.load();
Object prop = plist.getProperty("Resorts");
if(prop instanceof List) {
List<XMLPropertyListConfiguration> resorts = (List<XMLPropertyListConfiguration>) prop;
Log.i("AC",resorts.get(0).getClass().toString());
Log.i("AC",resorts.get(1).getClass().toString());
for(int i=0; i<resorts.size(); i++) {
String folder = (String) resorts.get(i).getProperty("Folder");
List<XMLPropertyListConfiguration> courses = (List<XMLPropertyListConfiguration>) resorts.get(i).getProperty("Courses");
Log.i("AC","Resort "+i+" in folder "+folder);
for(int j=0; j<courses.size(); j++) {
BigInteger course_index = (BigInteger) courses.get(j).getProperty("Index");
String course_name = (String) courses.get(j).getProperty("Name");
Log.i("AC","- Course "+course_index+": "+course_name);
}
}
}
} catch (ConfigurationException e) {
Log.e("AC","ConfigurationException");
e.printStackTrace();
}
}
这是我要解析的plist：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Resorts</key>
<array>
<dict>
<key>Courses</key>
<array>
<dict>
<key>Index</key>
<integer>1</integer>
<key>Name</key>
<string>Black Stork International</string>
</dict>
<dict>
<key>Index</key>
<integer>2</integer>
<key>Name</key>
<string>Black Stork Panorama</string>
</dict>
<dict>
<key>Index</key>
<integer>3</integer>
<key>Name</key>
<string>Black Stork Village</string>
</dict>
</array>
<key>Folder</key>
<string>01</string>
</dict>
</array>
</dict>
</plist>
在构建路径中，我添加了外部jar：
结果异常：

希望有一些大师为我提供答案：）
答案 0 :(得分：0)
异常“没有可用的验证Saxparser实现”确实是因为在文件XMLPropertyListConfiguration中将Saxparser工厂的验证设置为true。
最终我使用了这个解决方案： 我在项目的源文件夹中创建了新类XMLPropertyListConfiguration2，它与外部JAR中的XMLPropertyListConfiguration类相同，但验证更改为false。
然后在我的Activity的onCreate方法中，我使用了这个类而不是XMLPropertyListConfiguration。
