使用spring-boot配置自己的messageSource

标签： spring-boot

我使用的是spring-boot并且正在使用MessageSourceAutoConfiguration，但现在对于messageSource，我想使用parentMessageSource定义ResourceBundleMessageSource。但是，我无法通过启动的自动配置了解如何执行此操作。我尝试排除MessageSourceAutoConfiguration.class，但在尝试定义自己的messageSource bean时遇到了例外情况 非常感谢任何帮助。

答案 0 :(得分：1)

我在WebFlowConfig @Configuration类中定义了'messageSource'和'parentMessageSource'@ Bean。我将这两个@ Bean发送到他们自己的MessageConfig @Configuration类，一切正常！我的灵感来自于类似的问题：How do I add method based security to a Spring Boot project?并附有解释：

“尝试把...”{在这里插入你的bean}“...在一个单独的@Configuration类中。你似乎在ServletContext准备好之前强制它被实例化了......”
