進行更改後MappingJacksonHttpMessageConverter我在下面片段在我的pom.xml嵌套的例外是java.lang.NoClassDefFoundError：在pom.xml中
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
</parent>
，並得到了以下異常：去除後
nested exception is java.lang.NoClassDefFoundError: org/springframework/http/converter/json/MappingJacksonHttpMessageConverter
上面的標籤，這個春天的應用程序運行良好。我想知道爲什麼？
