首先出现:Annotations are not allowed here 贴一张图: 一开始没注意到那个分号,就戳了该注解的源码,检查它的target,作用于method,没错啊,并且value就是一个Class数组。百度一番无果,起身上了个洗手间,回来的时候,定睛一看,害,居然多了一个分号。在Java里边分号可以独立成为一条语句,就是代表啥也不干,但是它不...
首先出现:Annotations are not allowed here这个提示往往是注解的作用范围不允许,比如只能作用到Method的注解,却放到了class或者method内部。 贴一张图: 一开始没注意到那个分号,就戳了该注解的源码,检查它的target,作用于method,没错啊,并且value就是一个Class数组。百度一番无果,起身上了个洗手间,回来的时候,定睛...
【娱乐】@ExceptionHandler 提示 Annotations are not allowed here,程序员大本营,技术文章内容聚合第一站。
注意:在Java里边分号可以独立成为一条语句,就是代表啥也不干,但是它不是一个函数。故不管是idea在编码检查还是试图执行的时候,均会报错。(这句话摘自他人博客)
再向自定义注解添加元注解时,遇到一个错误 Annotations are not allowed here 排除写错和导入单元测试和Maven依赖的问题,百度一下并没有找到解决的办法,于是Google搜索一下,在SO上找到解决办法 意思就是说,在注解后面添加了“;”号导致的,一看自己的代码确实是这
New syntax is necessary mostly because they are not allowed inside class definitions in ES6. This is also why Yehuda proposed them when they switched Ember to ES6 (iirc - i can't find the right esdiscuss thread) Secondly, mutating decorators have implications for typing. If a decorator modif...
