Question

我将以下的ReloadableResourceBundleMessageSource实例化为Spring bean。

<bean id="resourceBundleMessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="locale/messages"/>
    <property name="cacheSeconds" value="-1"/>
    <property name="defaultEncoding" value="UTF-8"/>
</bean>

然后在我的服务bean中使用它：

@Qualifier("resourceBundleMessageSource")
private final ReloadableResourceBundleMessageSource messageSource;

@Autowired
public MyClassName(ReloadableResourceBundleMessageSource messageSource) {
    this.messageSource = messageSource;
}

public void myMethod() {
    String message = messageSource.getMessage("notification.sample", null, getUsersLocale(guest));
    // (...)
}

我的resources/locale/messages_en.properties看起来如下：

notification.sample: This is a sample translation.

但是它引发了以下异常：

[web.1]: SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.context.NoSuchMessageException: No message found under code 'notification.sample' for locale 'en'.] with root cause

尝试将@Autowired注释移动到字段，而不是构造函数。

@Autowired
@Qualifier("resourceBundleMessageSource")
private final ReloadableResourceBundleMessageSource messageSource;


public MyClassName() {

}

ReloadableResourceBundleMessageSource：org.springframework.context.NoSuchMessageException
