springboot/springmvc 获取项目中的所有请求路径
1. 编写业务代码
@Autowired
private WebApplicationContext applicationContext;
@GetMapping("/getAllURL")
public RestfulResult getAllURL() {
// 获取springmvc处理器映射器组件对象 RequestMappingHandlerMapping无法直接注入
RequestMappingHandlerMapping mapping = applicationContext.getBean(RequestMappingHandlerMapping.class);
//获取url与类和方法的对应信息
Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();
List<Map<String, Object>> result = new ArrayList<Map<String, Object>>();
for (Map.Entry<RequestMappingInfo, HandlerMethod> handlerMethodEntry : map.entrySet()) {
Map<String, Object> urlInfoMap = new HashMap<String, Object>();
RequestMappingInfo info = handlerMethodEntry.getKey();
HandlerMethod method = handlerMethodEntry.getValue();
// 获取url
PatternsRequestCondition patternsCondition = info.getPatternsCondition();
for (String url : patternsCondition.getPatterns()) {
urlInfoMap.put("url", url);
}
// 反射获取url对应类名和方法名
// 类名
urlInfoMap.put("className", method.getMethod().getDeclaringClass().getName());
// 方法名
urlInfoMap.put("method", method.getMethod().getName());
// 获取请求类型
RequestMethodsRequestCondition methodsRequestCondition = info.getMethodsCondition();
List<String> requestMethodList = new ArrayList<String>(methodsRequestCondition.getMethods().size());
for (RequestMethod requestMethod : methodsRequestCondition.getMethods()) {
requestMethodList.add(requestMethod.toString());
}
urlInfoMap.put("type", requestMethodList);
result.add(urlInfoMap);
}
return RestfulResult.getSuccessResult(result);
}
2. 异常信息
No qualifying bean of type 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping' available: expected single matching bean but found 3: swagger2ControllerMapping,requestMappingHandlerMapping,controllerEndpointHandlerMapping
原因就是： 基于 RequestMappingHandlerMapping.class 找到了三个 ，故加 上name属性获取

3. 调整后的代码
@Autowired
private WebApplicationContext applicationContext;
@GetMapping("/getAllURL")
public RestfulResult getAllURL() {
// 获取springmvc处理器映射器组件对象 RequestMappingHandlerMapping无法直接注入
Map<RequestMappingInfo, HandlerMethod> mapping = applicationContext.getBean("requestMappingHandlerMapping", RequestMappingHandlerMapping.class).getHandlerMethods();
//获取url与类和方法的对应信息
List<Map<String, Object>> result = new ArrayList<Map<String, Object>>();
for (Map.Entry<RequestMappingInfo, HandlerMethod> handlerMethodEntry : mapping.entrySet()) {
Map<String, Object> urlInfoMap = new HashMap<String, Object>();
RequestMappingInfo info = handlerMethodEntry.getKey();
HandlerMethod method = handlerMethodEntry.getValue();
// 获取url

}
return RestfulResult.getSuccessResult(result);
}
