[BUG] parseObject异常抛出文案不友好

oday-xiexin commented 2 years ago

问题描述

简要描述您碰到的问题。

环境信息

请填写以下信息：

OS信息： [e.g.：windows10]
JDK信息： [e.g.：Openjdk 1.8.0_312]
版本信息：[e.g.：Fastjson2 2.0.6]

重现步骤

如何操作可以重现该问题：

使用 xxx.xxx 方法
输入 ... 数据
出现 ... 错误
```
//可在此输入示例代码
```

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。 相比1.2.84 转换异常抛出的文案比较友好，如java.lang.Integer cannot be cast to com.alibaba.fastjson.JSONObject，但fastjson2 只会抛出com.alibaba.fastjson.JSONException: illegal input， offset 1, char 2

https://oss.sonatype.org/content/repositories/snapshots/com/alibaba/fastjson2/fastjson2/2.0.7-SNAPSHOT/

问题已经修复，已经和fastjson 1.x一样，补上错误信息。你可以先用2.0.7-SNAPSHOT版本验证
