这是Controller包下的：

package com.hsaipin.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.hsaipin.model.Activity;
import com.hsaipin.model.DataModel;
import com.hsaipin.model.Pager;
import com.hsaipin.service.ActivityService;

@Controller
public class ActivityController {
@Resource(name="activityService")
private ActivityService activityService;
@RequestMapping("activityList")
public ModelAndView activityList(Pager pager,Activity activity){
//根据搜索条件获得Activity列表的相关数据
DataModel<Activity> data=activityService.getActivityList(pager,activity);
//创建ModelAndView对象
ModelAndView mav=new ModelAndView("/jsp/activity/activity.jsp");
//把数据放入ModelAndView
mav.addObject("activityList", data.getRows());
mav.addObject("pager", data.getPager());
mav.addObject("activity", activity);
return mav;
}
}

这是Service包下的：

package com.hsaipin.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.hsaipin.dao.ActivityDao;
import com.hsaipin.model.Activity;
import com.hsaipin.model.DataModel;
import com.hsaipin.model.Pager;
import com.hsaipin.service.ActivityService;

@Service("activityService")
public class ActivityServiceImpl implements ActivityService{
@Resource
private ActivityDao activityDao;
@Override
public DataModel<Activity> getActivityList(Pager pager, Activity activity) {
//1.创建DataModel类型对象
DataModel<Activity> data =new DataModel<Activity>();
//2.查数据
//(1)根据搜索条件分页查询Activity列表
List<Activity> list=activityDao.findActivity(pager,activity);
//(2)根据搜索条件获得符合条件Activity数目
//3.把数据放入DataModel类型对象
data.setRows(list);
data.setPager(pager);
return data;
}
}

还有接口：

package com.hsaipin.service;

import com.hsaipin.model.Activity;
import com.hsaipin.model.DataModel;
import com.hsaipin.model.Pager;

public interface ActivityService {

DataModel<Activity> getActivityList(Pager pager, Activity activity);

}

这是dao包下的：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hsaipin.dao.ActivityDao">
<select id="findActivity" resultType="com.hsaipin.model.Activity">
SELECT * FROM car_activity
limit #{pager.from},#{pager.pageSize}
</select>
</mapper>

接口：

package com.hsaipin.dao;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import com.hsaipin.model.Activity;
import com.hsaipin.model.Pager;

public interface ActivityDao {

List<Activity> findActivity(@Param("pager")Pager pager,@Param("activity") Activity activity);

}

这是model：

package com.hsaipin.model;

public class Activity {
private Integer a_id; //活动 id
private String a_name; //活动名称
private String content; //活动内容
private String start_time; //开始时间
private String end_time; //结束时间
private String create; //创建者
private Integer is_del; //是否删除 0未删 1删除

public Integer getA_id() {
return a_id;
}
public void setA_id(Integer a_id) {
this. a_id= a_id;
}
public String getA_name() {
return a_name;
}
public void setA_name(String a_name) {
this.a_name = a_name;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getStart_time() {
return start_time;
}
public void setStart_time(String start_time) {
this.start_time = start_time;
}
public String getEnd_time() {
return end_time;
}
public void setEnd_time(String end_time) {
this.end_time = end_time;
}
public String getCreate() {
return create;
}
public void setCreate(String create) {
this.create = create;
}
public Integer getIs_del() {
return is_del;
}
public void setIs_del(Integer is_del) {
this.is_del = is_del;
}
}

页面，数据都有，数据库也连好了，为啥没数据啊？
