kindeditor的圖片上傳，報如下錯誤，在網上找了很久資料也沒解決，借此寶地，求大神指教：
1、圖片上傳其實也成功了。2、圖片上傳路徑、型別也入庫成功了。
就是報如下錯誤。
org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver.logException(AbstractHandlerExceptionResolver.java:197) - Resolved [org.springframework.http.converter.HttpMessageNotWritableException: No converter found for return value of type: class java.util.HashMap]
配置情況：pom.xml ,這些也是最新的了。
