   1.但我看实际传过来的数据Boolean类型的值是 T, 源码 `case tag == BC_TRUE: // 'T': //true` 就有处理

   @xfstart07  There is only classes definition，I don't find the unit test.

   查出的问题记录:
   1. https://github.com/apache/dubbo-go-hessian2/blob/master/object.go#L472
   断言 bool 值是返回的 err = nil, 导致无法报出实际的错误
   
   2.如果 Go 的结构体定义中存在小写开头字段,会导致解析出错,原本应该读取的数据没有读取,这样数据就错乱了

   @xfstart07 can u try to simulate the issue problem following the example below:
   - https://github.com/apache/dubbo-go-hessian2/blob/f989170905c309700aba409389fefcd8f02849b3/test_hessian/src/test/java/unit/GoStringTest.java?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L32

   1. 没明白 boolean 不支持是什么意思? 那 object.go#L472 支持的啥?
   2. 第二个问题准确的说是序列化读取数据时强依赖于 go struct 的定义,如果定义少了某个字段,数据读取就错乱了,我感觉是不合理的,不过我对 hessian 协议不是很理解,hessian 是有这个规定的吗?

   1:boolean 和 java.lang.Boolean 是不一样的，你使用的是Boolean在java那边定义，在go这边hessian2 暂时还不支持编解码，你可以改为boolean
   2:dubbo-go-hessian2 因为是按照字节顺序读取的,不支持skip. 建议使用的时候 序列化/反序列化的结构体是对应的。

   1: bool 在java 这边定义为boolean， 使用Boolean 现在还不支持.
   2:go结构体字段不要定义为小写，定义为小写无法编解码.
