接到运维反馈线上已正常运行一年多的服务下发短信功能异常，短信下发功能不可用一直报空指针异常，其他功能则正常。重启后恢复正常隔一段时间又复现。报错如下

关键位置：
at com.ebupt.cmi.sms.utils.Utils.doPost(Utils.java:167)
代码如下：
public static JSONObject doPost(RestTemplate restTemplate, String url, Object params) {
StringHttpMessageConverter t = new StringHttpMessageConverter();
//设置为false就可以修改header中的accept-charset属性
t.setWriteAcceptCharset(false);
restTemplate.getMessageConverters().add(0, t);
HttpHeaders header = new HttpHeaders();
header.setContentType(MediaType.APPLICATION_JSON_UTF8);
header.set(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_UTF8_VALUE);
header.set("accept-charset", "utf-8,gbk,gb2312");
log.info("params：{}", JSON.toJSONString(params));
HttpEntity httpEntity = new HttpEntity<>(params, header);
ResponseEntity response;
try {
response = restTemplate.postForEntity(url, httpEntity, String.class);
log.info("response：{}", JSON.toJSONString(response));
JSONObject json = JSONObject.parseObject(response.getBody());
if (response.getStatusCode() != HttpStatus.OK || !"0000".equals(json.get("code").toString())) {
log.warn("nurl：{}n负载：{}n result：{}", url, params, json);
return new JSONObject();
} else {
// log.info("nurl：{}n负载：{}n result：{}", url, params, json);
}
return json;
} catch (Exception e) {
log.error("",e);
return new JSONObject();
}
}
分析日志知道了入参完全没问题，同样的参数在重启后完全能正常发送，进入源码发送，第一反应可能时下游短信服务返回为空导致，但是短信服务功能正常，而且分析日志发现请求压根没到达短信服务，问题不在于此
查看异常堆栈第一行：
at org.springframework.web.client.RestTemplate$AcceptHeaderRequestCallback.canReadResponse(RestTemplate.java:862)
找到相应源码：
空指针是代码1处抛出，则是converter为null, 调用的地方是代码2,那么就是方法getMessageConverters()返回的list中有元素为空。
突然想到当初为了修改header中的accept-charset属性从网上无脑copy了几行代码贴在doPost方法里面：
默认的accept-charset非常长，下游接口接收的参数长度超长报错了，这才需要修改，但是用set方法设置了没有生效，百度一查说需要把StringHttpMessageConverter的writeAcceptCharset属性设置为false才会生效，这才复制粘贴了这几行代码。
导致每发送一次请求都会向restTemplate 里添加一个消息转换器：
解决方案将红框中的代码移到restTemplate bean注入的地方即可，还可以将
restTemplate.getMessageConverters().add(0, t);修改为：
restTemplate.getMessageConverters().set(1, t);也不会出错，无脑cv不可取！！！
但是报错应该是内存溢出而不是空指针，决定在本地模拟一下，果然报错是内存溢出：

为什么会报空指针暂时不知，先把问题解决然后存档以后慢慢查找！
