at com.alibaba.druid.support.http.WebStatFilter.doFilter(WebStatFilter.java:123) ~[druid-1.0.18.jar:1.0.18]由於Spring boot 已經放棄對velocity的集成支持，所以需要自己集成，集成中發現，設置 toolbox一直有報錯！
velocityViewResolver.setToolboxConfigLocation("velocity-toolbox.xml");
跟蹤發現
最終
應放置於
resources 資源目錄下新建 META-INF目錄 和resources子目錄 將velocity-toolbox.xml至於目錄下
經測可用
