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
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
<table class="tableList" >
<tr>
<th>类名</th>
<th>方法名</th>
<th>URL</th>
<th>类型</th>
<tr>
<c:forEach items="${list}" var="mvc" varStatus="status">
<tr id="${status.index}">
<td>${mvc.className}</td>
<td>${mvc.method}</td>
<td>
<c:choose>
<c:when test="${!fn:contains(mvc.url,'}') and (mvc.type=='GET' or mvc.type=='')}">
<a href="${ctx}${mvc.url}" target="_blank">${mvc.url}</a>
</c:when>
<c:otherwise>${mvc.url}</c:otherwise>
</c:choose>
</td>
<td>${mvc.type}</td>
</tr>
</c:forEach>
</table>
