spring mvc 获取所有的controller和url映射关系

标签：

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.   
6. import org.springframework.beans.factory.annotation.Autowired;  
7. import org.springframework.stereotype.Controller;  
8. import org.springframework.ui.Model;  
9. import org.springframework.web.bind.annotation.RequestMapping;  
10. import org.springframework.web.method.HandlerMethod;  
11. import org.springframework.web.servlet.mvc.condition.PatternsRequestCondition;  
12. import org.springframework.web.servlet.mvc.condition.RequestMethodsRequestCondition;  
13. import org.springframework.web.servlet.mvc.method.RequestMappingInfo;  
14. import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;  
15.   
16. @Controller  
17. public class MappingController {  
18.   
19.     @Autowired  
20.     private RequestMappingHandlerMapping requestMappingHandlerMapping;  
21.   
22.     @RequestMapping(value = "/mappings")  
23.     public String list(Model model) {  
24.         List<HashMap<String, String>> urlList = new ArrayList<HashMap<String, String>>();  
25.   
26.         Map<RequestMappingInfo, HandlerMethod> map = requestMappingHandlerMapping.getHandlerMethods();  
27.         for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {  
28.             HashMap<String, String> hashMap = new HashMap<String, String>();  
29.             RequestMappingInfo info = m.getKey();  
30.             HandlerMethod method = m.getValue();  
31.             PatternsRequestCondition p = info.getPatternsCondition();  
32.             for (String url : p.getPatterns()) {  
33.                 hashMap.put("url", url);  
34.             }  
35.             hashMap.put("className", method.getMethod().getDeclaringClass().getName()); // 类名  
36.             hashMap.put("method", method.getMethod().getName()); // 方法名  
37.             RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition();  
38.             String type = methodsCondition.toString();  
39.             if (type != null && type.startsWith("[") && type.endsWith("]")) {  
40.                 type = type.substring(1, type.length() - 1);  
41.                 hashMap.put("type", type); // 方法名  
42.             }  
43.             urlList.add(hashMap);  
44.         }  
45.         model.addAttribute("list", urlList);  
46.         return "/console/system/mappingList";  
47.     }  
48.   
49. }  

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.mvc.condition.PatternsRequestCondition;
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】

Java代码  

1. <table class="tableList" >  
2. <tr>  
3.         <th>类名</th>  
4.         <th>方法名</th>  
5.         <th>URL</th>  
6.         <th>类型</th>  
7. <tr>  
8.     <c:forEach items="${list}" var="mvc" varStatus="status">  
9.     <tr id="${status.index}">  
10.         <td>${mvc.className}</td>  
11.         <td>${mvc.method}</td>  
12.         <td>  
13.             <c:choose>  
14.             <c:when test="${!fn:contains(mvc.url,‘}‘) and (mvc.type==‘GET‘ or mvc.type==‘‘)}">  
15.                 <a href="${ctx}${mvc.url}" target="_blank">${mvc.url}</a>  
16.             </c:when>  
17.             <c:otherwise>${mvc.url}</c:otherwise>  
18.             </c:choose>  
19.         </td>  
20.         <td>${mvc.type}</td>  
21.     </tr>  
22.     </c:forEach>  
23. </table>  

	<table class="tableList" >
	<tr>
			<th>类名</th>
			<th>方法名</th>
			<th>URL</th>
			<th>类型</th>
	<tr>
		<c:forEach items="${list}" var="mvc" varStatus="status">
