，调用Service，指定查询条件查询对应的结果，返回List*/
@Test
public void findCollectionByConditionNoPage(){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
IElecTextService elecTextService = (IElecTextService) ac.getBean(IElecTextService.SERVICE_NAME);
ElecText elecText = new ElecText();
// elecText.setTextName("张");
// elecText.setTextRemark("张");
List list = elecTextService.findCollectionByConditionNoPage(elecText);
if(list!=null && list.size()>0){
for(ElecText elecText2:list){
System.out.println(elecText2.getTextName()+" "+elecText2.getTextDate()+" "+elecText2.getTextRemark());
}
}
}
真正的action：
package com.itheima.elec.web.action;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.itheima.elec.domain.ElecSystemDDL;
import com.itheima.elec.service.IElecSystemDDLService;
@SuppressWarnings("serial")
@Controller("elecSystemDDLAction")
@Scope(value="prototype")
public class ElecSystemDDLAction extends BaseAction{
ElecSystemDDL elecSystemDDL = this.getModel();
@Resource(name=IElecSystemDDLService.SERVICE_NAME)
private IElecSystemDDLService elecSystemDDLService;
public String home(){
List list = elecSystemDDLService.findKeywordWithDistinct();
request.setAttribute("list", list);
return "home";
}
public String edit(){
//获取数据类型
String keyword = elecSystemDDL.getKeyword();
//1：使用数据类型作为查询条件，查询数据字典表，返回List
List list = elecSystemDDLService.findSystemDDLListByKeyword(keyword);
request.setAttribute("systemList", list);
return "edit";
}
}
总结：根据什么样的条件查询，是在service层完成的，把所有的条件组织好后，给dao层，dao层再拼接SQL或者hql语句，进行真正的查询。web层的action只是传递参数，进行简单的调用service层的方法。?
