spring mvc 获取所有的controller和url映射关系

有时候需要根据url反查controller，如果能获取所有的url，则不用跟据url去代码里搜了，方便开发人员、调试人员或交接人。

关键对象：RequestMappingHandlerMapping

Java代码  

1. import java.util.ArrayList;
2. import java.util.HashMap;
3. import java.util.List;
4. import java.util.Map;
5. import org.springframework.beans.factory.annotation.Autowired;
6. import org.springframework.stereotype.Controller;
7. import org.springframework.ui.Model;
8. import org.springframework.web.bind.annotation.RequestMapping;
9. import org.springframework.web.method.HandlerMethod;
10. import org.springframework.web.servlet.mvc.condition.PatternsRequestCondition;
11. import org.springframework.web.servlet.mvc.condition.RequestMethodsRequestCondition;
12. import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
13. import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
14. @Controller
15. public class MappingController {
16. @Autowired
17. private RequestMappingHandlerMapping requestMappingHandlerMapping;
18. @RequestMapping(value = "/mappings")
19. public String list(Model model) {
20. List<HashMap<String, String>> urlList = new ArrayList<HashMap<String, String>>();
21. Map<RequestMappingInfo, HandlerMethod> map = requestMappingHandlerMapping.getHandlerMethods();
22. for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {
23. HashMap<String, String> hashMap = new HashMap<String, String>();
24. RequestMappingInfo info = m.getKey();
25. HandlerMethod method = m.getValue();
26. PatternsRequestCondition p = info.getPatternsCondition();
27. for (String url : p.getPatterns()) {
28. hashMap.put("url", url);
29. }
30. hashMap.put("className", method.getMethod().getDeclaringClass().getName()); // 类名
31. hashMap.put("method", method.getMethod().getName()); // 方法名
32. RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition();
33. String type = methodsCondition.toString();
34. if (type != null && type.startsWith("[") && type.endsWith("]")) {
35. type = type.substring(1, type.length() - 1);
36. hashMap.put("type", type); // 方法名
37. }
38. urlList.add(hashMap);
39. }
40. model.addAttribute("list", urlList);
41. return "/console/system/mappingList";
42. }
43. }

import java.util.ArrayList;

import java.util.Map;

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

import org.springframework.web.servlet.mvc.condition.RequestMethodsRequestCondition;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Controller
public class MappingController {

	@Autowired
	private RequestMappingHandlerMapping requestMappingHandlerMapping;

	@RequestMapping(value = "/mappings")
	public String list(Model model) {
		List<HashMap<String, String>> urlList = new ArrayList<HashMap<String, String>>();

		Map<RequestMappingInfo, HandlerMethod> map = requestMappingHandlerMapping.getHandlerMethods();
		for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {
			HashMap<String, String> hashMap = new HashMap<String, String>();
			RequestMappingInfo info = m.getKey();
			HandlerMethod method = m.getValue();
			PatternsRequestCondition p = info.getPatternsCondition();
			for (String url : p.getPatterns()) {
				hashMap.put("url", url);
			}
			hashMap.put("className", method.getMethod().getDeclaringClass().getName()); // 类名
			hashMap.put("method", method.getMethod().getName()); // 方法名
			RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition();
			String type = methodsCondition.toString();
			if (type != null && type.startsWith("[") && type.endsWith("]")) {
				type = type.substring(1, type.length() - 1);
				hashMap.put("type", type); // 方法名
			}
			urlList.add(hashMap);
		}
		model.addAttribute("list", urlList);
		return "/console/system/mappingList";
	}

}

然后再在页面上遍历list即可【java框架源码下载】

1. <table class="tableList" >
