我ReloadableResourceBundleMessageSource在我的 web 项目中使用，并将类注入到 servlet，问题是我想使用 Spring 注释注入类，但它似乎不起作用？我的代码是：
my.xml
我的.xml
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>classpath:myList</value>

myServletClass.java
myServletClass.java
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("my.xml");
String message = applicationContext.getMessage(message, null, "Default
", null);
}
How do I inject the ReloadableResourceBundleMessageSourceusing annotations?

Change the bean to autowire by name
将 bean 更改为按名称自动装配
<bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
autowire="byName">
<property name="basenames">
<list>
<value>classpath:myList</value>
</list>
</property>
<property name="cacheSeconds" value="1"/>
</bean>
Autowire the Message Source within your Servlet
在 Servlet 中自动装配消息源
public Class MyServlet extends HttpServlet{
@Autowired
MessageSource messageSource;
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException{
String message = messageSource.getMessage("test.prop", null, "Default",null);
}
}

src/main/resources/myList.properties
src/main/resources/myList.properties
test.prop=Hope this helps.
If you are not using Spring MVC you may need to create a Spring application context when starting your application. This can be configured in your Web.xml file using the ContextLoaderListener.
如果您没有使用 Spring MVC，您可能需要在启动应用程序时创建一个 Spring 应用程序上下文。这可以使用 ContextLoaderListener 在您的 Web.xml 文件中进行配置。

Did you try this in your servlet?
你在你的servlet中试过这个吗？
private ApplicationContext getApplicationContext() {
ApplicationContext wac =
WebApplicationContextUtils.getRequiredWebApplicationContext(
this.getServletContext());
return wac;
} // getAppliationContext
Then, when you want to gain access to the bean:
然后，当您想要访问 bean 时：
ReloadableResourceBundleMessageSource reloadableConfig =
(ReloadableResourceBundleMessageSource)
getApplicationContext().getBean("messageSource");
