<context:annotation-config> declares support for general annotations such as @Required, @Autowired, @PostConstruct, and so on.
<mvc:annotation-driven /> is actually rather pointless. It declares explicit support for annotation-driven MVC controllers (i.e.@RequestMapping, @Controller, etc), even though support for those is the default behaviour.
My advice is to always declare <context:annotation-config>, but don't bother with <mvc:annotation-driven /> unless you want JSON support via Jackson.
当我们需要controller返回一个map的json对象时,可以设定<mvc:annotation-driven />,
同时设定<mvc:message-converters> 标签,设定字符集和json处理类
本文深入解析了Spring MVC中的mvc:annotation-driven注解的意义、用途及应用场景,包括自动配置、数据绑定、JSON支持等核心功能,并探讨了如何在控制器返回JSON对象时的实践方法。
