可以打印出数据 但是存不进去
错误如下：：：

报的是sql语法错误，是因为你建表的使用了mysql的保留字作为字段名。从错误信息中可以看到condition和index字段都是保留字。改一下字段名称吧。
session.save(topic);后面是不是少了=》session.getTransaction().commit();
根据报错信息，是sql语句不正确，请检查下sql语句，例如字段名称，字段个数，数据与字段是否匹配
显示是sql语句有语法错误
先去看一下你这个Topic实体在hibernate-mapping里面的属性与数据库字段的映射是否有错误
上面没查出问题的话，根据你这个要存的对象，自己手写SQL语句到MYSQL管理器里面是执行一下看看能不能插入数据，会更明确到底错在哪里
另外你这个最后一段最好改成
try{
session.save(topic);
tx.commit();//事务提交
}catch(Exception e){
tx.rollback(); //事务回滚
throw(e);
}finally{
Writer out2=response.getWriter();
out2.write("success");
out2.close();
session.close(); //关闭session
}
