1 当web.xml中没有配置以下拦截时,会出现

<filter>
<filter-name>openSessionInView</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>sessionFactoryBeanName</param-name>
<param-value>sessionFactory</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>openSessionInView</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

103 note The full stack trace of the root cause is available in the Apache Tomcat/8.0.20 logs.

105 Apache Tomcat/8.0.20
当hibernate的javassist-GA.jar和Struts2的javassist-.GA.jar包冲突时,出现的错误,解决该错误方法:删除Struts2的javassist-3.11.0.GA.jar包,保留hibernate的javassist-3.11.0.GA.jar包

 

 所以解决该错误:

1 必须在web.xml配置好,拦截器

2 必须有Hibernate的javassist-3.18.1-GA.jar包,而且不能有Struts2的javassist-3.18.1-GA.jar,因为这两个jar包冲突。
