hibernate 映射问题

Question

断点调试的时候：
set 里面是这个错：
com.sun.jdi.InvocationException occurred invoking method后来我改了<hibernate-mapping default-lazy="true">
也不可以 

Answer 1

改了配置文件后：
        <set name="moduleSet" inverse="true" cascade="save-update" lazy="false">
                <key column="MODULENO"/>
                <one-to-many class="cn.com.liandisys.tcg.model.PrjModule"/>
        </set>报错变了

问题好像是处在Hibernet与数据库连接之间
