PathVariable not working at all

Question

For some reason, my @PathVariable annotation doesn’t work at all, after doing some Google search, I couldn’t find anyone else with the same problem, this is the code:

 @Controller @RequestMapping("/bot") public class BotController { @RequestMapping(value = "/test", method = RequestMethod.GET) public void test() { System.out.println("test"); Store.INSTANCE.getChatBot().postMessage("test"); } @RequestMapping(value = "/say/{text}", method = RequestMethod.GET) public void say(final @PathVariable("text") String text) { System.out.println("say: " + text); Store.INSTANCE.getChatBot().postMessage(text); } } 

This works: http://localhost:8080/GithubHookSEChatService/bot/test

This does not work: http://localhost:8080/GithubHookSEChatService/bot/say/realtest

Also, System.out.println("say: " + text) does not exist, the only other key that I have is:

 24-Aug-2014 17:25:21.611 WARNING [http-apr-8080-exec-24] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/GithubHookSEChatService/bot/say/realtest] in DispatcherServlet with name 'dispatcher' 

I'm running out of tips, does anyone know what is going on? Why don't the latter work?

My current web.xml :

 <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> </web-app> 

and

dispatcher-servlet.xml :

 <?xml version='1.0' encoding='UTF-8' ?> <!-- was: <?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" xmlns:context="http://www.springframework.org/schema/context"> <!-- auto scan --> <context:component-scan base-package="com.skiwi.githubhooksechatservice" /> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <value>classpath:githubhooksechatservice-environment.properties</value> </property> </bean> <!-- properties --> <bean id="configuration" class="com.skiwi.githubhooksechatservice.mvc.configuration.Configuration"> <property name="rootUrl" value="${env.rootUrl}"/> <property name="chatUrl" value="${env.chatUrl}"/> <property name="botEmail" value="${env.botEmail}"/> <property name="botPassword" value="${env.botPassword}"/> <property name="roomId" value="${env.roomId}"/> </bean> <!-- startup bean --> <bean name="startup" init-method="start" class="com.skiwi.githubhooksechatservice.mvc.beans.StartupBean" lazy-init="false" /> </beans> 

Answer 1

This problem, apparently, is not only related to @PathVariable , it also does not work:

 @RequestMapping(value = "/test/test", method = RequestMethod.GET) @ResponseBody public void test() { System.out.println("test"); Store.INSTANCE.getChatBot().postMessage("test"); } 

This is because there are several levels of subfolders, I found a solution to my problem in Spring MVC, how can I map sub-URLs like / settings /, / settings / users / and / settings / users / delete?

The only thing you need to do is include the following in dispatcher-servlet.xml :

 <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> 

And then everything works as expected!

I know this is an old question. But the answer will be helpful to others.

(1) Add the line below to dispatcher-servlet.xml, assuming the dispatcher is your DispatcherServlet name in web.xml

<mvc:annotation-driven/>
