我在xml文件中添加了下面的代码但是当我删除下面的代码然后它工作正常。所以请让我知道我在哪里做错了代码。
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
</bean>
<bean class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<array>
<bean class = "org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
</bean>
</array>
</property>
</bean>
我在
上有例外<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
<bean class="pakage">
<property name="domainManager" ref="domainManager" />
<property name="userProfileDao" ref="userProfileDao" />
</bean>
我的MVC-dispatcher-servlet.xml以及两个上面的bean标记

我花了一些时间来解释Spring文档中的大量读数。
在Spring MVC中，需要映射 请求 - ＆gt;处理程序对象 我们需要使用Handler Mapping接口。
这是在 org.springframework.web.servlet 中，因为Spring使用了servlet技术。
在dispatcher-servlet中，您可以实现任何处理程序映射。
但默认使用dispatcher-servlet，包含 BeanNameUrlHandletMapping 和 DefaultAnnotationHandlerMapping 。
<强>解决方案
由于BeanNameUrlHandletMapping默认为，因此您无需在调度程序中再次覆盖它。 如果您已经完成，只需删除即可正常。并为我工作。 ：D
有关详细信息，请参阅我的blog post。

您需要在配置中添加<mvc:annotation-driven />。使用<context:annotation-config />将启用对@Autowired等注释的支持。
您可以从配置中删除StringHttpMessageConverter和AnnotationMethodHandlerAdapter，因为它不会执行任何操作。支持所有媒体类型的StringHttpMessageConverter将由AnnotationMethodHandlerAdapter注册，然后通过添加<mvc:annotation-driven />进行注册。
