是什么导致 java.lang.IllegalStateException：为 HTTP 路径映射的不明确的处理程序方法

Question

我收到主题错误消息，但我不知道为什么。我有一组相当复杂的控制器。主体控制人如下：

package ws.daley.hollow.web.controller.admin;

import java.util.Locale;

import javax.annotation.PostConstruct;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;

    public MyModelAndView adminWithEntityNew(Model model, Locale locale) {return super.adminWithEntityNew(model, locale, getElementParameters());}

    @PostMapping(value = STUB, params = { ENTITY_NAME, SUBMIT })
    public MyModelAndView adminWithEntitySave(@ModelAttribute(ENTITY_NAME) PiProcessor entity, @RequestParam("action") String action, Model model, Locale locale)
    {
        return super.adminWithEntitySubmit(model, locale, action, entity);
    }
}

        {
            Collection<PiProcessor> piProcessors = this.piProcessorService.queryByNode(entity.getName());

            }
        }
        return super.adminWithEntitySubmit(model, locale, action, entity);
    }
}

参数为：

STUB=/server-admin
EDIT=edit
NEW=new
SUBMIT=submit

我还制作了一个 AbstractHandler 的副本，并将其放在我自己的源代码树中的包 org.springframework.web.servlet.handler 中。我添加了对它进行了以下更改：

添加

private static Logger logger = LoggerFactory.getLogger(AbstractHandlerMethodMapping.class);

添加

            logger.warn("Url :"+request.getContentType().toString());
            logger.warn("Request: "+request.toString());
            logger.warn("Context Path: "+request.getContextPath().toString());
            logger.warn("Method: "+request.getMethod().toString());
            logger.warn("Query string: "+request.getQueryString().toString());
            logger.warn("Scheme: "+request.getScheme().toString());
            Enumeration<String> e = request.getParameterNames();
            while(e.hasMoreElements())
            {
                String parameterName = e.nextElement();
                String parameter = request.getParameter(parameterName).toString();
                logger.warn("Parameter: "+parameterName+"->"+parameter);
            }
            logger.warn("matches:");
            for(Match match:matches)
                logger.warn("\t"+match.toString());
            logger.warn("bestMatch: "+bestMatch.toString());
            logger.warn("secondBestMatch: "+secondBestMatch.toString());

就在声明之前：

                    throw new IllegalStateException("Ambiguous handler methods mapped for HTTP path '" +
                        request.getRequestURL() + "': {" + m1 + ", " + m2 + "}");

输出是：

我忘了提到我使用的是 spring-boot 1.5.10.RELEASE 并且已经移动到 2.0.0.RC1 并且都有这个问题。

此外，在另外十几个模块中，我有完全相同的结构。 AdminPiProcessorController 是唯一表现出这种行为的模块。模型、存储库、服务和控制器被高度抽象化，以完全允许这种风格的代码。不幸的是，构建一个简单的测试用例变得非常困难。

Answer 1

虽然从技术上讲不是一个答案，但问题已经自行消失了。我认为类似的问题之前的行为方式相同......

Answer 2

你在两个控制器中有相同的映射

 AdminPiProcessorController 
 AdminNodeController 

因为映射对于应用程序来说是全局的，所以您不能为两个不同的控制器使用相同的 uri。

希望对你有帮助。

控制器类 AdminPiProcessorController ：

@GetMapping(value = STUB, params = ENTITY_NAME)
    @Override
    public MyModelAndView adminEditEntityList(Model model, Locale locale) {return super.adminEditEntityList(model, locale);}

具有与 AdminNodeController 中相同的映射

@GetMapping(value = STUB, params = ENTITY_NAME)
    @Override
    public MyModelAndView adminEditEntityList(Model model, Locale locale) {return super.adminEditEntityList(model, locale);}

请检查其他方法。
