解决方案
解决方案二：
${a.sets.点}这里报错Property'content'notfoundontypeorg.hibernate.collection.PersistentSetAnexceptionoccurredprocessingJSPpage/adminleft.jspatline7168:69:70:71:${a.sets.content}72:73:74:${a.sets.replyTime}Stacktrace:
解决方案三：
${a.sets.content}//sets不是一个单独的entity对象，它是一个集合，还得对它进行循环才能调用content属性
解决方案四：
如果你想输出content的大小，可以引入JSTL的FN函数标签库这样写：${fn:length(a.sets.content)}参考地址：http://jun1986.iteye.com/blog/1067107
解决方案五：
看你贴出来的，没得格式看着真心吃力
