org.springframework.web.servlet.FrameworkServlet.initServletBean Initializing Servlet 'MVC'

As an AI language model, I do not have enough context to provide a complete answer. However, I can tell you that this message is related to the initialization of a Spring MVC Framework Servlet. The FrameworkServlet is a core component of the Spring MVC framework that handles HTTP requests and responses. When the servlet is initialized, the initServletBean method is called to set up the servlet's configuration and other related properties.

这是一个 Spring MVC 中的异常，提示请求的 Content-Type 是 'application/json;charset=UTF-8'，但是后台并没有相应的消息转换器将其转化为对应的 Java 对象，导致服务无法处理请求。可能需要在 Spring 配置文件中增加相应的消息转换器，例如使用 Jackson 库将 JSON 字符串转化为 Java 对象。

这个错误提示是因为 Spring 框架中没有支持 'text/plain;charset=UTF-8' 这种类型的数据传输。你可以修改请求的 Content-Type，或者在 Spring 配置文件中添加一个支持该类型的转换器。具体方法可以参考以下步骤：

1. 修改请求的 Content-Type，例如改为 'application/json'。
2. 在 Spring 配置文件中添加一个支持 'text/plain;charset=UTF-8' 的转换器，例如：

<bean class="org.springframework.http.converter.StringHttpMessageConverter">
	<property name="supportedMediaTypes">
		<list>
			<value>text/plain;charset=UTF-8</value>
		</list>
	</property>
</bean>

这样应该就可以解决这个错误了。
