您好我正在尝试使用 Xstream 解析器将以下 xml 转换为对象。我尝试使用下面的代码来转换 xml，但我得到了

Duplicate field ERRORS
---- Debugging information ----
field               : ERRORS
class               : com.avidev9.Fees.GCSFeesResponse$DebitsWSDS
required-type       : com.avidev9.Fees.GCSFeesResponse$DebitsWSDS
converter-type      : com.thoughtworks.xstream.converters.reflection.ReflectionConverter
path                : /DebitsWSDS/ERRORS[2]
line number         : 1
version             : null

我使用的代码

   xstream.alias("DebitsWSDS", DebitsWSDS.class);
            xstream.alias("DEBITS", DebitsWSDS.DEBITS.class);
            xstream.alias("list", DebitsWSDS.class);
            xstream.addImplicitCollection(DebitsWSDS.class, "ERRORS");


            xstream.alias("ERROR_ID", String.class);
            xstream.alias("TABLE_NAME", String.class);
            xstream.alias("TABLE_ID", String.class);
            xstream.alias("ROW_ID", String.class);
            xstream.alias("ERROR_TEXT", String.class);
            xstream.alias("ERROR_CODE", String.class);
            xstream.alias("COLUMN_ID", String.class);
            xstream.alias("ERROR_TYPE", String.class);

        public DEBITS DEBITS;

    public class ERROR {
        public String TABLE_NAME;

        public String ERROR_CODE;
        public String COLUMN_ID;
        public String ERROR_TYPE;
    }

    public class DEBITS {

通过 xstream 处理 List 有点棘手。您需要为部分添加implicitCoolection

xstream.alias("list", ERRORS.class);
xstream.addImplicitCollection(ERRORS.class, "ERRORS");

希望这可以帮助！！

在您的班级中，您有字符串和整数变量的组合。但是在使用 alias() 时，您只提到了String.class.

您应该将所有变量声明为 String 并尝试运行您的代码。
