POST-Anfrage mit Feder RestTemplate - BadRequest 400

Hoffen, dass ein Feder-guru helfen könnte, mich auf diese,
Iam-Entwicklung eines multi-web-servces-Anwendung, die Alle diese Web-Services basieren auf einem Glas genannt-basierte-server, die haben alle base-Klassen, die vererbt werden können, wo immer erforderlich.
Also das base-server-Projekt habe ich eine BaseClient Klasse, die hat eine Feder RestTemplate Eigenschaft.
wenn ich versuche, mit diesem client (Ursache-Erben) in eine tatsächliche umgesetzte web service Klasse, wenn ich versuche zu tun POST-Anforderung, es gibt mir http 400 Bad Request Fehler. Aber es funktioniert ohne Probleme für GET-Anforderungen.
Appriciate, wenn jemand kann mir zeigen wo ich falsch lag.

RestTemplate in Base-server

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
   <constructor-arg ref="httpClientFactory"/> 

    <property name="messageConverters">
        <list>
            <bean id="jsonViewResolver" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" >
               <property name="objectMapper" ref="JacksonObjectMapper" />               
               <property name="supportedMediaTypes">
                          <list>
                            <bean class="org.springframework.http.MediaType">
                               <constructor-arg value="application" />
                               <constructor-arg value="json" />
                               <constructor-arg value="#{T(java.nio.charset.Charset).forName('UTF-8')}"/>
                             </bean>
                          </list>
                </property>
            </bean> 
            <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
            <bean class="org.springframework.http.converter.StringHttpMessageConverter" />                              
        </list>
    </property>
</bean>
<bean id="JacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper" />

 <bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
    <constructor-arg ref="httpClientParams"/>
</bean>

 <bean id="httpClientParams" class="org.apache.commons.httpclient.params.HttpClientParams">

    <property name="connectionManagerClass"
              value="org.apache.commons.httpclient.MultiThreadedHttpConnectionManager"/>
</bean>

<bean id="httpClientFactory" class="org.springframework.http.client.CommonsClientHttpRequestFactory">
    <constructor-arg ref="httpClient"/>
</bean>

 <bean id="baseClient" class="com.tapgift.base.client.BaseClientImpl" >
    <property name="restTemplate" ref="restTemplate" />
 </bean>

Tatsächliche Nutzung dieser resttemplate

@Override
public BaseResponse updateItemAvailableQuantity(final String token,final Integer qty, final Integer itemId) {
    LOG.info("Entering method: updateItemAvailableQuantity : param:- token= "+ token+", qty= "+ qty+", itemId= "+ itemId);
    MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
    map.add("token", token);
    map.add("itemId", itemId.toString());
    map.add("qty", qty.toString());
    return getRestTemplate().postForEntity("http://localhost:8080/merchant/api/merchant/update_item_qty",
    map, BaseResponse.class).getBody();
}

Diese Methode nicht ausführen, es gibt mir Fehler BadRequest, Folgenden ist der Endpunkt der anderen web-service.

@RequestMapping(value = "/merchant/update_item_qty", method = RequestMethod.POST)
public @ResponseBody BaseResponse updateAvailableQuantity(@RequestParam("token") String token,
        @RequestParam("itemId") final Integer itemId, @RequestParam("qty") final Integer qty)
{

    return getItemSupport().updateAvailableQuantity(token, qty,itemId);
}

Dies ist die cosole Fehler.

resttemplate

Gut, endlich fand ich den Grund für das scheitern, Es ist in der Tat ein verfy lustige Lösung. Was ich Tat, war die Reihenfolge geändert der Bohnen von messagesConvertersvon restTemplate
bean.

Früher war es,

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">

<property name="messageConverters">
    <list>
        <bean id="jsonViewResolver" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" >
           <property name="objectMapper" ref="JacksonObjectMapper" />               
           <property name="supportedMediaTypes">
                      <list>
                        <bean class="org.springframework.http.MediaType">
                           <constructor-arg value="application" />
                           <constructor-arg value="json" />
                           <constructor-arg value="#{T(java.nio.charset.Charset).forName('UTF-8')}"/>
                         </bean>
                      </list>
            </property>
        </bean> 
        <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
        <bean class="org.springframework.http.converter.StringHttpMessageConverter" />                              
    </list>
</property>

und ich habe ihn an folgenden Reihenfolge,

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
   <constructor-arg ref="httpClientFactory"/> 

    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
            <bean class="org.springframework.http.converter.StringHttpMessageConverter" /> 
            <bean id="jsonViewResolver" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" >
               <property name="objectMapper" ref="JacksonObjectMapper" />               
               <property name="supportedMediaTypes">
                          <list>
                            <bean class="org.springframework.http.MediaType">
                               <constructor-arg value="application" />
                               <constructor-arg value="json" />
                               <constructor-arg value="#{T(java.nio.charset.Charset).forName('UTF-8')}"/>
                             </bean>
                          </list>
                </property>
            </bean> 

        </list>
    </property>
</bean>

und es funktionierte.
Ist es nicht eine komische Lösung?
