SpringBoot環境下 XStream XML與Bean 相互轉換

SpringBoot環境下 XStream XML與Bean 相互轉換

---

SpringBoot環境下，XML轉對象時，同一個類無法進行轉換，原因是因爲SpringBoot重新加載了對象；若未指定classloader的時候，SpringBoot未正確使用classloader，需要指定classloader，需要在方法中指定加載的類，添加如下代碼：
xstream.setClassLoader(clazz.getClassLoader());

如：

public static <T> T toBean(Class<T> clazz, String xml) {
    try {
        XStream xstream = new XStream();
        xstream.processAnnotations(clazz);
        xstream.autodetectAnnotations(true);
        return (T) xstream.fromXML(xml);
    } catch (Exception e) {
        log.error("[XStream]XML轉對象出錯:{}", e.getCause());
        throw new RuntimeException("[XStream]XML轉對象出錯");
    }
}

更改爲：

public static <T> T toBean(Class<T> clazz, String xml) {
        try {
            XStream xstream = new XStream();
            xstream.processAnnotations(clazz);
            xstream.autodetectAnnotations(true);
            xstream.setClassLoader(clazz.getClassLoader());
            return (T) xstream.fromXML(xml);
        } catch (Exception e) {
            log.error("[XStream]XML轉對象出錯:{}", e.getCause());
            throw new RuntimeException("[XStream]XML轉對象出錯");
        }
    }
