This article mainly explains "how to get all the interfaces of the Springboot project". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to get all the interfaces of the Springboot project".

Catalogue

The Springboot project gets all interfaces

Get the information of all http interfaces under the project

Interface information class

II. Unit testing

The Springboot project gets all interfaces @ Autowiredprivate WebApplicationContext applicationContext; @ Overridepublic List getAllUrl () {RequestMappingHandlerMapping mapping = applicationContext.getBean (RequestMappingHandlerMapping.class); / / gets the corresponding information between url and classes and methods Map map = mapping.getHandlerMethods (); List list = new ArrayList (); for (Map.Entry m: map.entrySet ()) {Map map1 = new HashMap (); RequestMappingInfo info = m.getKey (); HandlerMethod method = m.getValue () / / get the class name of the current method Class bean = method.getBeanType (); / / use reflection to get the annotated content of the current class Api api = bean.getAnnotation (Api.class); RequestMapping requestMapping = bean.getAnnotation (RequestMapping.class); String [] value = requestMapping.value () Map1.put ("parent", value [0]) / / get the annotations on the method and the annotation values ApiOperation methodAnnotation = method.getMethodAnnotation (ApiOperation.class); String privilegeName = methodAnnotation.notes (); PatternsRequestCondition p = info.getPatternsCondition (); for (String url: p.getPatterns ()) {map1.put ("url", url) } map1.put ("className", method.getMethod (). GetDeclaringClass (). GetName ()); / / Class name map1.put ("method", method.getMethod (). GetName ()); / / method name RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition (); for (RequestMethod requestMethod: methodsCondition.getMethods ()) {map1.put ("type", requestMethod.toString ()) } list.add (map1);} return list;} get the information of all http interfaces under the project 1. Interface information class

Create a new class to store information about the http interface

Class RequestToMethodItem {public String controllerName; public String methodName; public String requestType; public String requestUrl; public Class [] methodParmaTypes; public String getControllerName () {return controllerName;} public void setControllerName (String controllerName) {this.controllerName = controllerName;} public String getMethodName () {return methodName } public void setMethodName (String methodName) {this.methodName = methodName;} public String getRequestType () {return requestType;} public void setRequestType (String requestType) {this.requestType = requestType;} public String getRequestUrl () {return requestUrl } public void setRequestUrl (String requestUrl) {this.requestUrl = requestUrl;} public Class [] getMethodParmaTypes () {return methodParmaTypes;} public void setMethodParmaTypes (Class [] methodParmaTypes) {this.methodParmaTypes = methodParmaTypes } public RequestToMethodItem (String requestUrl, String requestType, String controllerName, String requestMethodName, Class [] methodParmaTypes) {this.requestUrl = requestUrl; this.requestType = requestType; this.controllerName = controllerName; this.methodName = requestMethodName; this.methodParmaTypes = methodParmaTypes;}} II. Unit test

Write two http interfaces for testing

Import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.ResponseBody @ Controllerpublic class TestController {@ GetMapping (value = "/ test1") @ ResponseBody public void test1 (Integer a) {} @ PostMapping (value = "/ test2") @ ResponseBody public void test2 (Integer AME Integer b) {}}

Test unit

Import java.util.ArrayList;import java.util.List;import java.util.Map;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner;import org.springframework.web.context.WebApplicationContext;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;import cn.hutool.json.JSONUtil; / / hutool is a very convenient toolkit @ SpringBootTest@RunWith (SpringRunner.class) public class Test {@ Autowired WebApplicationContext applicationContext; @ org.junit.Test public void index () {List requestToMethodItemList = new ArrayList () RequestMappingHandlerMapping requestMappingHandlerMapping = applicationContext.getBean (RequestMappingHandlerMapping.class); Map handlerMethods = requestMappingHandlerMapping.getHandlerMethods (); for (Map.Entry requestMappingInfoHandlerMethodEntry: handlerMethods .entrySet ()) {RequestMappingInfo requestMappingInfo = requestMappingInfoHandlerMethodEntry.getKey (); RequestMethodsRequestCondition methodCondition = requestMappingInfo.getMethodsCondition () PatternsRequestCondition patternsCondition = requestMappingInfo.getPatternsCondition (); HandlerMethod mappingInfoValue = requestMappingInfoHandlerMethodEntry.getValue (); / / request type String requestType = methodCondition.getMethods () .toString () / / request path String requestUrl = patternsCondition.getPatterns () .iterator () .next (); / / Controller name String controllerName = mappingInfoValue.getBeanType () .toString () / / request method name String requestMethodName = mappingInfoValue.getMethod () .getName (); / / request parameter Class [] methodParamTypes = mappingInfoValue.getMethod () .getParameterTypes () / / Spring performs unified exception handling through BasicErrorController, excluding these API if ("class org.springframework.boot.autoconfigure.web.servlet.error.BasicErrorController" .equals (controllerName)) {continue } RequestToMethodItem item = new RequestToMethodItem (requestUrl, requestType, controllerName, requestMethodName, methodParamTypes); requestToMethodItemList.add (item) } System.out.println (JSONUtil.toJsonStr (requestToMethodItemList));}}
