1.java代码：
确定是由于【PageHelper.orderBy(params.get("orderBy").toString());】这段代码引起的
@Override
public List<Clerk> findClerkList(Map<String, Object> params) {
PageHelper.startPage(((Integer) params.get("pageNum")),
((Integer) params.get("pageSize")));
if (params.containsKey("orderBy")) {
if (!StringUtil.empty(params.get("orderBy").toString())) {
PageHelper.orderBy(params.get("orderBy").toString());
}
}
List<Clerk> clerkList = clerkMapper.findClerkList(params);
for (Clerk c : clerkList){
String sellerStartLevel = StartLevelEnum.getEnumValueByKey(c.getSellerStartLevel());
c.setSellerStartLevel(sellerStartLevel);
}
return clerkList;
}完整异常如下：
由【net.sf.jsqlparser.JSQLParserException】可看出是因为组装的sql语句解析过程中抛出"非RuntimeException异常"，异常被程序捕抓处理且未出现新异常，异常后的代码继续执行，所以不影响一个完整Retrieve操作。而一些"RuntimeException异常"，例如：空指针(NullPointerException)、数组越界(IndexOutOfBoundsException)、类型转换(ClassCastException)等会被JVM自动处理，会在console控制台捕抓并打印异常日志。

SELECT
1 AS all_apply_customer,
count(if(xataa.accept_status = 1, TRUE, NULL)) AS accept_apply_customer,
count(if(xataa.accept_status = 0, TRUE, NULL)) AS reject_apply_customer,
count(if(xataa.accept_status = 2, TRUE, NULL)) AS invalid_apply_customer
FROM xft_apply_task_assign_agent xataa
ORDER BY all_apply_customer DESC3. 从PageHelper官网看到其是引用了sql解析工具jsqlparser.jar，是工具包抛出的异常
虽然后台抛出JSQLparseException，但是不影响sql查询结果。
原因是count函数中嵌套了if函数导致抛异常，不使用“count(if(exprt))”嵌套函数就不会出现异常；
看到有博主留言说将sql写成视图就不会出现这个异常，亲测后，仍然会抛异常；
升级pagehelper的版本为v4.1.6仍旧会抛异常；
