006杰信—factory更新数据

本博客的资源全部来源于传智播客。

factroy更新的执行流程和003杰信-在jsp页面输入数据，然后在oracle数据库中插入factory数据，当字段允许为空时要特殊处理差不多，

1.在jFactoryList.jsp页面选中一个要更新的数据，

2.来到更新页面，jFactoryUpdate.jsp,回显刚才选中的那个factory的数据。

3.输入要修改的数据。点击确定后来到新的action请求。onclick="formSubmit('updatefactory.action','_self');"

4.根据那个新的action的请求，来到 FactoryController类，找到@RequestMapping("/basicinfo/factory/updatefactory.action")

就是FactoryController.java里面的updatefactory方法。

根据jfactoryupdate.action这个action请求来到FactoryController.java类。执行public String factoryupdate(String id ,Model model)方法：

   //跳转到修改的页面
    //根据传入的参数id来找到要修改的Factory.
    @RequestMapping("/basicinfo/factory/jfactoryupdate.action")
    public String factoryupdate(String id ,Model model)
    {//根据id找到一个Factory，然后把这个factory传给jsp页面，然后在页面上回显数据并做修改。
        //为什么取名叫做obj呢，就是为了后续拷贝的时候少做修改。
        Factory obj=factoryService.get(id);
        model.addAttribute("obj", obj);
        return "/basicinfo/factory/jFactoryUpdate.jsp";

    }

2.来到更新页面，jFactoryUpdate.jsp,

            <div>

                <div>
                    <table class="commonTable" cellspacing="1">
                        <tr>

                        <tr>
                            <td class="columnTitle_mustbe">联系人：</td>
                            <td class="tableContent"><input type="text" name="contacts"  value="${obj.contacts}"/></td>

                        </tr>

                </div>
            </div>
    </form>
</body>
</html>

4.根据那个新的action的请求，来到 FactoryController类

package cn.itcast.jk.controller.basicinfo.factory;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import cn.itcast.jk.controller.BaseController;
import cn.itcast.jk.domain.Factory;
import cn.itcast.jk.service.FactoryService;
@Controller
public class FactoryController extends BaseController {
  @Resource
    FactoryService factoryService;

    //列表
    @RequestMapping("/basicinfo/factory/list.action")
    public String list(Model model)
    {

        List<Factory> datalist=factoryService.find(null);
        model.addAttribute("datalist", datalist);//将我的数据传递到页面；

        return "/basicinfo/factory/jFactoryList.jsp";

    }

    //跳转到修改的页面
    //根据传入的参数id来找到要修改的Factory.
    @RequestMapping("/basicinfo/factory/jfactoryupdate.action")
    public String factoryupdate(String id ,Model model)
    {//根据id找到一个Factory，然后把这个factory传给jsp页面，然后在页面上回显数据并做修改。
        //为什么取名叫做obj呢，就是为了后续拷贝的时候少做修改。
        Factory obj=factoryService.get(id);
        model.addAttribute("obj", obj);
        return "/basicinfo/factory/jFactoryUpdate.jsp";

    }
    //保存新修改的数据
    @RequestMapping("/basicinfo/factory/updatefactory.action")
    public String updatefactory(Factory factory)
    {
        factoryService.update(factory);
        return "redirect:/basicinfo/factory/list.action";

    }

}

  factoryService.update(factory);就是执行BaseDaoImpl.java代码

package cn.itcast.jk.dao.impl;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.beans.factory.annotation.Autowired;

import cn.itcast.jk.dao.BaseDao;
import cn.itcast.jk.pagination.Page;

public abstract class BaseDaoImpl<T> extends SqlSessionDaoSupport implements BaseDao<T>{
    @Autowired
    //mybatis-spring 1.0无需此方法；mybatis-spring1.2必须注入。
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){
        super.setSqlSessionFactory(sqlSessionFactory);
    }
     private String ns;        //命名空间
    public String getNs() {
        return ns;
    }
    public void setNs(String ns) {
        this.ns = ns;
    }

    public List<T> findPage(Page page){
        List<T> oList = this.getSqlSession().selectList(ns + ".findPage", page);
        return oList;
    }

    public List<T> find(Map map) {
        List<T> oList = this.getSqlSession().selectList(ns + ".find", map);
        return oList;
    }
    public T get(Serializable id) {
        return this.getSqlSession().selectOne(ns + ".get", id);
    }

    public void insert(T entity) {
        this.getSqlSession().insert(ns + ".insert", entity);
    }

    public void update(T entity) {
        this.getSqlSession().update(ns + ".update", entity);
    }

    public void deleteById(Serializable id) {
        this.getSqlSession().delete(ns + ".deleteById", id);
    }

    public void delete(Serializable[] ids) {
        this.getSqlSession().delete(ns + ".delete", ids);
    }
}

执行FactoryMapper.xml里面的update。

FactoryMapper.xml代码:
