找到这个字段的定义, 或者getter方法.

You will need a field bridge.

For example:

@Field(index = Index.NO, store = Store.YES)
@FieldBridge(impl = MyFieldBridge.class)
private byte[] file;

//The file bridge
public class MyFieldBridge implements StringBridge {

    @Override
    public String objectToString(final Object object) {

        byte[] file = (byte[]) object;

        return MagicFileUtil.getTextContent(file)
    }
}

由于没有找到这个MagicFileUtil类,所以自己转换byte[]==>String

MyFieldBridge.java改成

import org.hibernate.search.bridge.StringBridge;

public class MyFieldBridge implements StringBridge {

    @Override
    public String objectToString(final Object object) {

        byte[] file = (byte[]) object;

        //return MagicFileUtil.getTextContent(file);
        return String.valueOf(file);
    }
}
