@JFinal 请问帖子方法里面的@Before({Condition.class, KlassListSeoInter.class})， 其中的KlassListSeoInter.class方法是什么呢？我的paras一直是空，运行到cond.buildSql(sql, paras);就报错，创建的拦截器继承自 Interceptor可以吗。

JFinal3.0复杂查找如何实现？

@JFinal 非常感谢您！

入门：在demo多加了一个表遇到问题

插入数据失败

@Irin.Chan 是public void save()没被执行，请问这是怎么回事呢？

插入数据失败

//保存
@Before(ClothesValidator.class)
public void save() {
System.out.println("ClothesController save1");
getModel(Clothes.class).save();
System.out.println("ClothesController save2");
redirect("/clothes");
System.out.println("ClothesController save3");
}
控制台：
Before invoking /clothes/save
After invoking /clothes/save

JFinal action report -------- 2017-04-02 16:14:48 ------------------------------
Url : POST /clothes/save
Controller : com.demo.clothes.ClothesController.(ClothesController.java:1)
Method : save
Interceptor : com.demo.clothes.ClothesInterceptor.(ClothesInterceptor.java:1)
com.demo.clothes.ClothesValidator.(ClothesValidator.java:1)
Parameter : clothes.pattern=6 clothes.clothesNum=6 。。。。。。
本来应该有printed出来ClothesController save123的，为什么没有？

插入数据失败

2017-04-02 16:17

发现public void save() {
getModel(Clothes.class).save();
redirect("/clothes");
}
这段代码是没有被执行的，怪不得提交不了，不过为什么没被执行呢。。。

已解决：
1、jar包导入错误
2、没开MSQL
3、改着改着代码少了个（）
4、我真的好小白T_T
