今天将项目从eclipse导入到idea时 项目启动报了如上的错误,debug启动 下面代码发现 configClass是有获取到class文件路径的 但是运行到下一步时 temp依然是null 最后导致项目启动失败 不知道这种情况到底是什么原因造成的,希望能得到前辈们的指点

   try {

                temp = Class.forName(configClass).newInstance();

            } catch (Exception var4) {

                throw new RuntimeException("Can not create instance of class: " + configClass, var4);

            }

            if (temp instanceof JFinalConfig) {

                this.jfinalConfig = (JFinalConfig)temp;

            } else {

                throw new RuntimeException("Can not create instance of class: " + configClass + ". Please check the config in web.xml");

            }
