关于dom4j解析xml的小问题 - Java / Java相关

package com.javabean.xml;

import java.net.MalformedURLException;
import java.net.URL;
import org.dom4j.io.SAXReader;
import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.VisitorSupport;

public class test {
public static void main(String[] args) {
Document document;
try {
document = new test().parse(new URL(
"http://www.douban.com/feed/people/aasd/interests"));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
bar(document); <------这个位置报错:局部变量 document 可能尚未初始化
}
public Document parse(URL url) throws DocumentException {
SAXReader reader = new SAXReader();
Document document = reader.read(url);
return document;
}

public static void bar(Document document) {
Element root = document.getRootElement();
String content = root.asXML();
System.out.println(content);
}
}

错误就是上面那一个求解决方法
