Json解析数据遇到的问题

最近做项目的时候，涉及多次Json解析，但是突然发现调用同一种解析方法，竟然有的成功，有的不能成功，一下就懵逼了。。

先上代码：

public class ProjectParamVo {
@JsonProperty("VERSION")
private String version;

@JsonProperty("BUSINESSID")
private String businessId;

@JsonProperty("PARAMS")
private List<ProjectParamParamVo> params = new LinkedList<ProjectParamParamVo>();

//构造器,getter/setter

}

InputStream f = new FileInputStream(f);

BufferedReader br = new BufferedReader(new InputStreamReader(f));
String line = null;
while ((line = br.readLine()) != null) {
data.append(line);
}
br.close();
businessID = JsonUtil.getParamJsonId(data.toString());

public static String getParamJsonId(String data) throws IOException {
if (data == null || data.isEmpty()) {
return null;
}

ProjectParamVo paramVo = JsonUtil.getObjectMapper().readValue(data, ProjectParamVo.class);
return paramVo.getBusinessId();
}

文件内容：

{
"BUSINESSID" : "00000001",
"PARAMS" : [ {
"desc" : " ",
"edittype" : "0",
"selData" : "",
"tag" : "03000001",
"value" : "450001"
}{
"desc" : "适用于NAC",
"edittype" : "0",
"selData" : "",
"tag" : "04000014",
"value" : "8134"
}{
"desc" : "1是0否，第一位：消费撤销，第二位：预授权撤销，第三位：预授权完成撤销，第四位：预授权完成（请求）",
"edittype" : "0",
"selData" : "",
"tag" : "02000002",
"value" : "0111"
} ],
"VERSION" : "150803093707"
}

代码怎么看都没问题，跟文件内容比较觉得可以准确解析，可现实总是那么骨感：org.codehaus.jackson.JsonParseException: Unexpected character ('e' (code 101)): was expecting comma，经过排除查找了才发现。。原来中文乱码竟然会有影响。。马不停蹄地改了上面文件流的传入编码：

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(f), "utf-8"));

问题解决。
