Shiro配置Session检测时Quartz版本冲突

项目背景: shiro 1.3 + quartz 2.x

2018-9-11 22:20:35补充:

经过测试,本人发现 ,通过实现 org.apache.shiro.session.mgt.ExecutorServiceSessionValidationScheduler  同样能解决相关问题,具体原因正在查找.

利用该类进行实现则不必自定义了.完整配置如下:(异同部分已高亮)

<!-- 配置session的定时验证检测程序类，以让无效的session释放 -->
    <bean id="sessionValidationScheduler"
          class="org.apache.shiro.session.mgt.ExecutorServiceSessionValidationScheduler">
        <!-- 设置session的失效扫描间隔，单位为毫秒 -->
        <property name="interval" value="1800000"/>
        <!-- 随后还需要定义有一个会话管理器的程序类的引用 -->
        <property name="sessionManager" ref="sessionManager"/>
    </bean>

如果上面的方式不能解决问题,那么可以选择下面这种方式:

-------------------------------------------------------------------------华丽的分割线--------------------------------------------------------------------------------------------

期初的session会话配置如下:

 <bean id="sessionValidationScheduler"
          class="org.apache.shiro.session.mgt.quartz.QuartzSessionValidationScheduler">
        <!-- 设置session的失效扫描间隔，单位为毫秒 -->
        <property name="sessionValidationInterval" value="1800000"/>
        <!-- 随后还需要定义有一个会话管理器的程序类的引用 -->
        <property name="sessionManager" ref="sessionManager"/>
    </bean>

class="org.apache.shiro.session.mgt.quartz.QuartzSessionValidationScheduler" 默认shiro使用的是这个来编译,但是quartz2.x之后实现方式变了,所以需要自定义实现:自定义实现类如下:

代码是从网上找的,也试过没啥问题.直接复制就好,不需要做修改.
