Cannot instantiate the type Map<String,Boolean>

无法实例化类型Map<String,Boolean>

错误代码:

Map<String, Boolean> modelPropertys = new Map<String, Boolean>();

看了一下Map的定义,public abstract interface java.util.Map

原来是抽象接口,不能直接实例化,需要使用它的实现类;

正确写法如下:

Map<String, Boolean> modelPropertys = new HashMap<String, Boolean>();

javaBean与Map&lt;String,Object&gt;互转

1. 为什么要实现javaBean与Map<String,Object>相互转换? 用过spring的都知道spring的MVC框架中有一个BaseCommandController对象,利用这个对象我们就可以很方便的将从客户端传递过来的参数封装到一个JavaBean对象中去,而不需要我们request.getParameter("name");bean.setName(name);了,从而也简化了不少的工作.如果大家用过BeanUtils.populate的话,就知道,这

升级AutoMapper后遇到的“Missing map”与“Missing type map configuration or unsupported mapping”问题

前几天发现 AutoMapper 3.3 的一个性能问题(详见:遭遇AutoMapper性能问题:映射200条数据比100条慢了近千倍),于是将 AutoMapper 升级至最新的 5.1.1 看是否也存在这个性能问题. 升级中想当然地将之前的map配置代码: Mapper.CreateMap<AEntity, ADto>(); Mapper.CreateMap<BEntity, BDto>(); 改为: Mapper.Initialize(cfg => cfg.Create
