Question

我的控制器方法由我的自定义注释注释。当我选择它们时，我会收到方法列表，我想获取每种方法的URL。

例如：

@RequestMapping("/test")
@Controller
public class TestController {

    @RequestMapping(method = RequestMethod.GET)
    public String methodOne(){}

    @RequestMapping(value = "/2", method = RequestMethod.GET)
    public String methodTwi(){}

}

我想收到：

for methodOne - / test

for methodTwo - / test / 2

这样的事可能。首先使用映射3个URL的2个方法编写一个控制器：

@Controller
@RequestMapping("/test")
public class DemoController {

    @RequestMapping(method = RequestMethod.GET)
    public String firstMethod(Model model) {
        model.addAttribute("name", "Olivier");
        return "firstPage";
    }

    @RequestMapping(method = RequestMethod.GET, value = {"/demo", "/demo1"})
    public String secondMethod(Model model) {
        model.addAttribute("name", "Olivier");
        return "secondPage";
    }
}

然后在你的@Configuration类中创建RequestMappingHandlerMapping bean：

@Configuration
public class DemoSpringApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoSpringApplication.class, args);
    }

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping mapping = new RequestMappingHandlerMapping();
        return mapping;
    }
}

创建一个反转Map的特殊控制器：

@Controller
@RequestMapping("/requests")
public class RequestMappingController {
    @Autowired
    private RequestMappingHandlerMapping handler;

    @RequestMapping(method = RequestMethod.GET)
    public String showDoc(Model model) {
        model.addAttribute("methods", handler.getHandlerMethods());
        Map<RequestMappingInfo, HandlerMethod> map = handler.getHandlerMethods();

        Set<RequestMappingInfo> mappings = map.keySet();
        Map<String, String> reversedMap = new HashMap<String, String>();
        for(RequestMappingInfo info : mappings) {
            HandlerMethod method = map.get(info);
            reversedMap.put(method.toString(), info.getPatternsCondition().toString());
        }
        model.addAttribute("methods", reversedMap);

        return "showDoc";
    }
}

在showDoc页面中，遍历新构建的地图：

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Documentation</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
    <h1>Documentation of Spring MVC URL's</h1>
    <p th:each="methods: ${methods}">
        <p><span th:text="'JAVA method:' + ${methods.key} + ', URL:' + ${methods.value}"></span></p>
    </p>
</body>
</html>

这将提供以下视图（按方法排序并提供映射的URL）：
