今天对接服务器接口获取数据的时候,一直返回获取失败,但不报错.一开始一直以为联网逻辑的问题,但是在联网层打印log是可以拿到返回的数据的,好奇怪的样子,折腾了足足两个小时,来回换了几种联网操作都不行,最后把问题定位在json解析过程中,需要说明一下,我们公司用的是retrofit2框架,数据解析也封装在里面了,但是如果解析失败控制台不打印任何log,这就很坑了,我用as插件gsonformat自动生成的bean,直接上图吧

你能看出来有哪里不对吗
对,没错,倒数第三个字段cr,gsonformat自动生成的是int型的,而注意看json串里的sData集合里有三个对象,第一个对象的cr是77,第二个是23,第三个是12.3,那么问题就出在这里,gsonformat会根据第一个对象的cr是77来设定类型,所以自动生成为int型,而这个cr是有可能是带小数点的,所以应该为float或者double型才对,太坑了有没有!!!
