为什么每个类只能有一个构造器被标记为required=true????????????????
规定的吧,如果设置两个构造函数required=true运行会出现下列错误
Invalid autowire-marked constructor: public com.imooc.beanannotation.jsr.JsrServie(). Found another constructor with 'required' Autowired annotation: public com.imooc.beanannotation.jsr.JsrServie(com.imooc.beanannotation.jsr.JsrDAO)
