java Spring MVC国际化不起作用
我试图让我的网络应用程序根据用户选择的语言显示不同的标签,但我似乎无法让它正常工作。它确实在读信息。每当我更改servlet xml文件中的“defaultLocale”时,属性和消息\u de.properties文件。。。?朗=恩和。。。?然而,lang=de根本不起作用
<property name="defaultLocale" value="de" />
我的xml文件如下:
网络。xml
<?xml version="1.0" encoding="UTF-8"?>

# 1 楼答案
您在根上下文中错误地定义了MVC处理(
<context:component-scan>
在控制器上,<mvc:annotation-driven>
在application-context.xml中)。将其移动到servlet上下文(SpringTest3-sevlet.xml)并通过以下方式初始化locale拦截器:同时删除不必要的处理程序映射定义(
ControllerClassNameHandlerMapping
)如果您不确定root和servlet上下文之间有什么区别,请查看有关此主题的其他答案(例如Difference between applicationContext.xml and spring-servlet.xml in Spring Framework)
