  1. POPOST request with Spring RestTemplate- BadRequest 400
    text
    copied!<p>Hope a Spring guru could help me on this, Iam developing a multi web servces application, All these Web Services are based on a Jar called based-server, which got all base classes which can be inherited where ever required. So this base-server project i have a BaseClient class which has a spring RestTemplate property. when i try to use this client (of cause inheriting) in a actual implemented web service class, when i try to do POST request it gives me http 400 Bad Request error. However it works without giving any trouble for GET requests. Appriciate if someone can point out where i got it wrong.</p> <p>RestTemplate in Base server</p> <pre><code>&lt;bean id="restTemplate" class="org.springframework.web.client.RestTemplate"&gt; &lt;constructor-arg ref="httpClientFactory"/&gt; &lt;property name="messageConverters"&gt; &lt;list&gt; &lt;bean id="jsonViewResolver" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" &gt; &lt;property name="objectMapper" ref="JacksonObjectMapper" /&gt; &lt;property name="supportedMediaTypes"&gt; &lt;list&gt; &lt;bean class="org.springframework.http.MediaType"&gt; &lt;constructor-arg value="application" /&gt; &lt;constructor-arg value="json" /&gt; &lt;constructor-arg value="#{T(java.nio.charset.Charset).forName('UTF-8')}"/&gt; &lt;/bean&gt; &lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean class="org.springframework.http.converter.FormHttpMessageConverter" /&gt; &lt;bean class="org.springframework.http.converter.StringHttpMessageConverter" /&gt; &lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean id="JacksonObjectMapper"

&lt;/bean&gt; </code></pre> <p>Actual usage of this resttemplate</p> <pre><code>@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&lt;String, String&gt; map = new LinkedMultiValueMap&lt;String, String&gt;(); 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(); } </code></pre> <p>This method does not execute, it gives me BadRequest error, Following is the end point of other web service.</p> <pre><code>@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); } </code></pre> <p>This is the cosole error.</p> <pre><code> 13:21:41,851 ERROR [STDERR]
