Hibernate里不能获得session值

Question

那就是你的super.getHibernateTemplate()这个没有得到
检查你的spring中sessionFactory配置文件注入是否正确

Answer 1

spring的配置文件，大家看看有没什么问题： 
<!-- DataSource --> 
    <bean id="dataSource" 
        class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
        <property name="driverClassName" 
        value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/> 
        <property name="url" 
        value="jdbc:sqlserver://localhost:1433;DatabaseName=MyOffice;SelectMethod=cursor"/> 
        <property name="username" value="sa"/> 
        <property name="password" value="123456"/> 
    </bean>     <!-- SessionFactory --> 
    <bean id="sessionFactory"

Answer 2

executeFind 具有LAZY特性，CRUD操作你配置openSessionInView了么，或是关了LAZY再就是给LZ个其他建议<property name="mappingResources">
            <list>
                <value>org/jb/y272/team4/entity/UserInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/FileInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/Schedule.hbm.xml </value>
                <value>org/jb/y272/team4/entity/ReadCommonMessage.hbm.xml </value>
                <value>org/jb/y272/team4/entity/ManualSign.hbm.xml </value>
                <value>org/jb/y272/team4/entity/MyNote.hbm.xml </value>
                <value>org/jb/y272/team4/entity/LoginLog.hbm.xml </value>
                <value>org/jb/y272/team4/entity/DepartInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/Message.hbm.xml </value>
                <value>org/jb/y272/team4/entity/OperateLog.hbm.xml </value>
                <value>org/jb/y272/team4/entity/AccessoryFile.hbm.xml </value>
                <value>org/jb/y272/team4/entity/BranchInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/FileTypeInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/MeetingInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/MessageToUser.hbm.xml </value>
                <value>org/jb/y272/team4/entity/MessageType.hbm.xml </value>
                <value>org/jb/y272/team4/entity/PreContract.hbm.xml </value>
                <value>org/jb/y272/team4/entity/RoleInfo.hbm.xml </value>
                <value>org/jb/y272/team4/entity/RoleRight.hbm.xml </value>
                <value>org/jb/y272/team4/entity/Sysdiagrams.hbm.xml </value>
                <value>org/jb/y272/team4/entity/SysFun.hbm.xml </value>
                <value>org/jb/y272/team4/entity/UserState.hbm.xml </value>
                <value>org/jb/y272/team4/entity/WorkTime.hbm.xml </value>
           </list>
</property> 
以上一段，既然都在同一目录下，可以写成，下面这个属性的作用就是读取classes下org/jb/y272/team4/entity目录下的所有标签
<property name="mappingDirectoryLocations">
<list>
<value>classpath:org/jb/y272/team4/entity</value>
</list>
</property>

Answer 3

有日志吗？
log4j的日志看一下
八成是配置文件错了。
特别是spring里的配置

Answer 4

super.getHibernateTemplate().executeFind(new HibernateCallback() （出错地方）{ 
这里应该不是最终出错地方吧..回调应该可以进入回调方法里面.你在回调方法里面打一个断点测试一下最终出错地点是哪才好判断`
