在之前并没有报这个错。因为添加了一个struts的json JAR包，报错。猜测是JAR包版本冲突。

<!-- struts2 -->
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.16</version>
<!-- 这里的 exclusions 是排除包，因为 Struts2中有javassist，Hibernate中也有javassist,
所以如果要整合Hibernate，一定要排除掉Struts2中的javassist，否则就冲突了。-->
<exclusions>
<exclusion>
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- json格式和map格式的对应 -->
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>2.3.16</version>
</dependency>
