Unclosed character class near index 2 ],[

今天做项目用了一个切割字符串，断点在String[] s = sb.toString().replaceAll("],[", "=").split("=");这里报错。![]()
报 Unclosed character class near index 2 ],[的错但检查代码一直感觉不出有什么问题，后来想起以前培训的时候讲师说过有一些特殊的东西在java中有特殊的用途，所以在使用他们的时候要加上转移符所以就改成String[] s = sb.toString().replaceAll("\\],\\[", "=").split("=");这样![]()
就可以了
