代码段：

@RequestMapping(method = RequestMethod.POST)//,  headers = "content-type=application/x-www-form-urlencoded")
public ModelAndView create(@RequestBody UserAccountBean account) {
    try{
        accounts.put(account.assignId(), account);
    }catch(RuntimeException ex)
    {
        return new ModelAndView("account/registerError");
    }
    return new ModelAndView("account/userVerification");
}

收到请求后，我得到的是Http状态代码415：服务器拒绝了此请求，因为请求实体的格式不受请求的方法所请求的资源的支持。

如果我将代码更改为此：

代码段：

@RequestMapping(method = RequestMethod.POST,headers = "content-type=application/x-www-form-urlencoded")
public ModelAndView create(@RequestBody UserAccountBean account) {
    try{
        accounts.put(account.assignId(), account);
    }catch(RuntimeException ex)
    {
        return new ModelAndView("account/registerError");
    }
    return new ModelAndView("account/userVerification");
}

我将获得405方法不允许。有趣的是，在响应的allow标头中，它列出了GET和POST作为允许的方法。

我有一个做JOSN映射的类：

@Component
public class JacksonConversionServiceConfigurer implements BeanPostProcessor {

private final ConversionService conversionService;

@Autowired
public JacksonConversionServiceConfigurer(ConversionService conversionService) {
    this.conversionService = conversionService;
}

public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
    return bean;
}

public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
    if (bean instanceof AnnotationMethodHandlerAdapter) {
        AnnotationMethodHandlerAdapter adapter = (AnnotationMethodHandlerAdapter) bean;
        HttpMessageConverter<?>[] converters = adapter.getMessageConverters();
        for (HttpMessageConverter<?> converter : converters) {
            if (converter instanceof MappingJacksonHttpMessageConverter) {
                MappingJacksonHttpMessageConverter jsonConverter = (MappingJacksonHttpMessageConverter) converter;
                jsonConverter.setObjectMapper(new ConversionServiceAwareObjectMapper(this.conversionService));
            }               
        }
    }
    return bean;
}

}

从Spring示例复制。与JSON内容类型配合使用时效果很好。

一个更普遍的问题是如何使spring mvc请求处理程序与不同的请求内容类型一起工作。任何建议将不胜感激。
