Something went wrong when using spring boot with jboss

Question

When I used spring-boot with the wildfly, something went wrong. The following is my application and conf.

1. pom.xml:

   <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.5.1.RELEASE</version>
   </parent>
   
   <dependencies>
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
           <exclusions>
               <exclusion>
                   <groupId>org.springframework.boot</groupId>
                   <artifactId>spring-boot-starter-tomcat</artifactId>
               </exclusion>
           </exclusions>
       </dependency>
   
       <dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>servlet-api</artifactId>
           <version>3.0-alpha-1</version>
       </dependency>
   </dependencies>
   

2. Main code: Application.java (return JSON data)

   @RequestMapping("/")
   public Map<String, String> hello() {
       Map<String, String> retMap = new HashMap<String, String>();
       retMap.put("success", "true");
       return retMap;
   }
   

3. Wildfly version:

   WildFly 8.1.0.Final

4. Exception:
