如何利用JAXBContext Unmarshaller读取xml里面的汉字?

Question

JAXBContext jc = JAXBContext.newInstance(A.class);
Unmarshaller un = jc.createUnmarshaller();
un.setSchema(getSchema());

如果我的xml文件里面包含了汉字,那么就会产生, 错误, 有没有什么办法可以做到可以在xml写汉字,读取不出错呢?

是不是你自己xml文件编码问题，我这样不会有问题：
[code="java"]

import java.io.FileReader;
import java.io.FileWriter;
import java.io.Writer;
import java.util.Date;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

import com.ulinkwo.example.Event;

public class XmlMashaller {

private static final String XML = "event.xml";

public static void main(String[] args) throws Exception {
    marshall();
    unmarshall();
}

private static void marshall() throws Exception {
    Event event = new Event();
    event.setDate(new Date());
    event.setName("开机");

    JAXBContext context = JAXBContext.newInstance(Event.class);
    Marshaller m = context.createMarshaller();
    m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
    m.marshal(event, System.out);

    Writer w = null;
    try {
        w = new FileWriter(XML);
        m.marshal(event, w);
    } finally {
        try {
            w.close();
        } catch (Exception e) {
        }
    }
}

private static void unmarshall() throws Exception {
    JAXBContext jc = JAXBContext.newInstance(Event.class);
    Unmarshaller un = jc.createUnmarshaller();
    Event event = (Event) un.unmarshal(new FileReader(XML));

    System.out.println(event.getName());

}

}

先生成xml，再解析出来。
