如果spring 版本为4.3.4 disparcher-servlet 中就得用 MappingJackson2HttpMessageConverter 相应的pom中那个jackson 依赖就得换成这三个

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.5</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.5</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.8.5</version>
</dependency>

还要修改JsonUtil。。。一连串的连锁反映啊
