【问题讨论】：
将您的记录器转为 DEBUG 并重试。它应该会告诉您问题出在哪里。 是的，我在 Spring 4.0.0 上工作得很好。我们需要查看这些日志。 添加了日志和日志语句。 您的日志似乎完全不相关。将您的日志级别设置为 DEBUG 并发送得到 406 响应的请求。 我的日志记录被搞砸了，更新了与页面被点击时间相关的正确日志记录。我认为 Java 没有正确地编组为 XML。我一直在寻找像 JSON 的 jackson 插件这样的 XML mashaller，但还没有找到。 【参考方案1】：406 表示请求内容被服务器视为不可接受。尝试删除Accept 标头或将headers="Accept=*/*" 添加到@RequestMapping 注释中。
【讨论】：
我觉得你说错了。它与请求的内容无关。该请求指定它在其Accept 标头中接受的内容类型。如果服务器无法生成该内容，它会以 406 响应。
我尝试添加 [code]header="Accept=*/*"[/code] 但它仍然不起作用。见编辑。我知道问题是响应，问题是我不知道如何修复响应。【参考方案2】：
只是花了几个小时来研究这个，所以我要离开这里，什么对我有用（我正在使用 Spring 4.0.6）以及我认为对你有用的东西（Spring 3.0.x )。
春季 4.0.x
由于MappingJackson2HttpMessageConverter 自动选择Jackson 数据绑定库并启用带有@ResponseBody 注释的控制器方法以自动返回JSON，因此通常假设XML 也存在这样的工具，但事实并非如此。
为了启用 XML，我必须手动创建一个带有两个消息转换器的 RequestMappingHandlerAdapter，一个 MarshallingHttpMessageConverter，后跟一个 MappingJackson2HttpMessageConverter。
这也允许使用 Spring 提供的任何编组器，只需将其设置为 MarshallingHttpMessageConverter 的属性即可。
结果spring-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- ... -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller">
<bean class="org.springframework.oxm.xstream.XStreamMarshaller"></bean>
</property>
</bean>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
</list>
</property>
</bean>
<!-- ... -->
</beans>
春季 3.0.x
注意：我假设此版本来自您的 x-servlet.xml 中的架构位置。
根据http://spring.io/blog/2013/05/11/content-negotiation-using-spring-mvc和http://spring.io/blog/2013/06/03/content-negotiation-using-views/，有两种方法可以在Spring 3中实现你想要的。第一种是使用ContentNegotiationManager，它仅从3.2.x版本开始可用，因此不适用于你的版本。第二个是使用ContentNegotiatingViewResolver，它根据请求的内容类型将视图的解析委托给其他解析器（无论是由Accept 标头定义，通过扩展，还是默认情况下是可配置的）。
基本上，您需要为ContentNegotiatingViewResolver 配置两个解析器，一个用于 XML，另一个用于您的 JSP 视图。
spring-servlet.xml:
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="viewResolvers">
<list>
<bean class="org.springframework.web.servlet.view.XmlViewResolver">
<property name="location" value="spreadsheet-views.xml"/>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="WEB-INF/views"/>
<property name="suffix" value=".jsp"/>
</bean>
</list>
</property>
</bean>
例如，您可以为 JSON 添加视图解析器，但您必须实现它，因为 Spring 没有提供。第二篇博文展示了如何实现一个简单的。

【参考方案3】：我在尝试解决同一问题时遇到了这个问题。在查看 pfac 的答案后，我发现只需将 jackson-dataformat-xml 库添加到我的项目中即可解决我的问题。
如果使用 maven：
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.3.2</version>
</dependency>
【讨论】：
【参考方案4】：我正在努力解决类似的问题。尽管我在注释中设置了“produces=application/xml”参数，但由于某种原因，我的 Web 应用程序似乎没有默认提供 xml 数据类型。
我只是通过为我的 applicationContext.xml 添加额外的 bean 配置来解决它：
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="defaultContentType" value="application/xml" />
</bean>
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" />
或通过 Java Config 类：
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter
@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer)
configurer.defaultContentType(MediaType.APPLICATION_XML);
