对接口方法进行抽象 

@Data
public class ControllerMethodItem {
	public String controllerName;
    public String methodName;
    public String requestType;
    public String requestUrl;
    public Class<?>[] 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;
