java.lang.reflect.InvocationTargetException报错

//1.接收数据
BufferedReader reader = request.getReader();
String params = reader.readLine();//json的字符串
//转为int[] 数组 params = "[1,2]"
int[] id = JSON.parseObject(params, int[].class);
上面的代码是把接收过来的数据进行JSON.parseObject(params, int[].class);转换，但是在运行的时候报的错是：
java.lang.reflect.InvocationTargetException
代码
mybatis里面的代码：

web.Servlet里面的代码：

service里面的代码：

mapper里面接口

这是你上面发的拿过来转换的，用的是fastjson，如果用的一样，你看看是不是获取的数据有问题
