NullableKey：解决Dictionary中键不能为null的问题 zt

2012-12-29 02:26 by 老赵, 1745 visits 众所周知,.NET中Dictionary的键不能为null,否则会抛出NullReferenceException,这在某些时候会显的很麻烦.与此相对的是Java中的HashMap支持以null为键,则方便许多.尽管null的确不是个好东西,但它既然已经存在,既然给我们造成了麻烦,我们就要想办法去解决它.实现一个自己的字典类自然可行,但要精心实现一个高效的字典并不是件容易的事情,例如BCL中的Dictionary.cs就有超…

解决spring中不同配置文件中存在name或者id相同的bean可能引起的问题

小总结: 如果启用组件扫描,bean名称不同时,Spring将尝试创建一个bean,即使该类的bean已经在spring-config.xml中定义了. 但是,如果在spring配置文件中定义的bean和自动发现的bean具有相同的名称,那么在组件扫描时,spring不会创建一个新的bean. spring.xml 与 spring-mvc.xml 定义具有相同名称的 bean 后者覆盖前者 如果一个bean没有一个no-args构造函数,至少有一个构造函数必须是自动连接的. 如果没有构造函数是…
