“请求的资源不可用”在Tomcat

Question

我收到请求的资源（）在浏览器中显示不可用，我无法理解我做错了什么。

我知道，关于这个问题的帖子太多但是我还是这个错误， 阅读官方文档对我没有帮助spring boot maven plugin。

在IDE（嵌入式tomcat）上正常工作。

这是我的pom.xml

主要应用类

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
  return application.sources(Application.class);
  }
  public static void main(String[] args) {
  SpringApplication.run(Application.class, args);
}

}

主控制器

@Controller
public class MainController {

  @RequestMapping("/")
  public String index(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
  model.addAttribute("name", name);
  return "index";
  }

}

此示例工作没有问题java sample war

在Catalina日志中我可以看到错误

  

“引起：java.lang.NoSuchMethodError：java.util.concurrent.ConcurrentHashMap.keySet（）Ljava / util / concurrent / ConcurrentHashMap $ KeySetView;”

阅读这个可以通过java版本的不匹配来生成，在我的编辑器中我从java8开始然后我下降到7，目前我正在使用maven3构建，使用open-jdk 7和Tomcat7相同
