jackson json-lib配合完成xml json互换

前段时间优化性能,将原来用的json-lib转换为了jackson,现在要解析xml,发现jaconson解析xml有问题,它对数组元素直解析最后一个,真不知是出于什么考虑?

 

而json-lib则没有这个问题,但是json-lib输出的json格式有些多余的双引号转义,不是很标准,它生成的json是无法让jackson解析的。

 

尝试了xstream,要自己写代码解析,不能用。

 

最后只好两个结合起来用:

 

  public static Map<String,Object> parseXml(String xml){
        try
        {
            xml = xml.replaceAll(">\s+<", "><");
            JSON json1 = (new XMLSerializer()).read(xml);
            String resoult = null;
            Map<String,Object> map = null;
            if(json1.isArray())
            {
                JSONArray jsonarray = (JSONArray)json1;
                map = (Map<String,Object>)jsonarray.get(0);
            }else{
                map = (Map<String,Object>)json1;
            } 

            return map;
        }
        catch (Exception e)
        {
            throw ExceptionUtils.silence(e);
        }
    }

 

转换为map后就好说了,再用jackson来转换为string

public static String toJsonString(Object obj) {
		if (null == obj) {
			return "null";
		}
		StringWriter writer = new StringWriter();
		ObjectMapper mapper = new ObjectMapper();
		try {
			mapper.writeValue(writer, obj);
		} catch (Exception e) {
			throw ExceptionUtils.silence(e);
		}

		return writer.toString();
	}
