在代碼中調用ResponseBody註解進行jasn注入,引入jackson包後出現問題,Request processing failed; nested exception is java.lang.IllegalArgumentException: No converter found for return value of type: class com.pawn.ssm.bean.Msg,刪掉導入的jackson包依然報這個錯誤,錯誤緣由,導入的jackson包未起做用,解決方法,在mvc配置文件中添加對<mvc:annotation-driven />的註解,添加內容爲html
1 <mvc:message-converters> 2 <bean class="org.springframework.http.converter.StringHttpMessageConverter"> 3 <property name="supportedMediaTypes"> 4 <list> 5 <value>text/plain;charset=UTF-8</value> 6 </list> 7 </property> 8 </bean> 9 </mvc:message-converters>
問題得以解決,java
