Tomcat/Spring - get parameters not decoded

Question

For some reason my Tomcat/Spring configuration doesn't automatically decode the GET parameters ( I assume it should be done automatically ).

Here is my setup:

@RestController public class MyController { @RequestMapping(value = "/do-something", method = RequestMethod.GET) public String doSomething(RequestPojo req) { // req.getPhone -- is not decoded, ie might be something like 00%204 instead of 004 } } public class RequestPojo { private String phone; // getter and setter }

Here is the content of mvc-dispatcher-servlet:

<mvc:default-servlet-handler/> <mvc:annotation-driven> <mvc:message-converters register-defaults="false"> <ref bean="customJsonHttpMessageConverter"/> </mvc:message-converters> </mvc:annotation-driven> <context:component-scan base-package="com.onoff.controller"> <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/> </context:component-scan> <bean id="multipartResolver" name="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="1073741824"/> <property name="defaultEncoding" value="utf8"/> </bean> <bean id="customJsonHttpMessageConverter" class="com.onoff.util.CustomJsonHttpMessageConverter"> <property name="supportedMediaTypes" value="application/json; charset=utf-8"/> </bean>

I've checked some suggestions before posting. URIEncoding="UTF-8" is specified in server.xml in Tomcat.

Any clues? Any help/suggestions will be highly appreciated.

Thank you in advance.

00%204 isn't the same as 004. It's the same as 00 4. Maybe your parameters are being doubly encoded? — user207421

Yes, sorry, it should be "00 4". No, my parameters aren't encoded twice — user3489820

1. You do not need to configure a message converter for JSON. As long as the Jackson Jars on are the class path this message converter will automatically be supported so I would remove that from the config. 2. I believe the "supportedMediaTypes" should just be "application/json" not "application/json; charset=utf-8" If you are going to set this as the media type then you have to set that in the header as the ContentType value instead of "application/json" — BrianC

3. If it still is not working I would try changing doSomething(RequestPojo req) to doSomething(@RequestBody RequestPojo req). If that makes no difference then I would start taking a detailed look at the request because something is likely off in the way the content is coming in or the way the headers are being passed. — BrianC

Please try with @ModelAttribute

 public String doSomething(@ModelAttribute RequestPojo req) { // req.getPhone -- is not decoded, ie might be something like 00%204 instead of 004 }
