Conclusion:golang不支持解析string然后执行。golang的反射机制只能存在于已经存在的对象上面。It is not known whether the subsequent versions are planned, and now only the registration can be loaded, and then a reflection similar to the Java Factory pattern is implemented.code example: T: = reflect.

the original code when expanding the function. Regardless of the software refactoring level, when the new recruits take over the boss's code, I think the most headache is to increase demand, because you do not know what to change the code to bring a hidden BUG.We always ideal can use the "plug-in" thinking to adapt to demand, write a good framework, and then classify, each of the abstract role is a large container, and then each time to the container plug into a plug-in, to a demand, do a plug-
