#### 使用springboot遇到问题 ####

Found multiple occurrences of org.json.JSONObject on the class path:
    
            jar:file:/C:/Users/Chloe/.m2/repository/org/json/json/20140107/json-20140107.jar!/org/json/JSONObject.class
            jar:file:/C:/Users/Chloe/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class
