在springmvc中的controller所对应的函数中,如果需要从*.jsp页面中获取数据,可以自行在函数括号中写,springmvc会自动封装传过来的值。
spring-mvc.xml 中加入如下语句:
1

3
4
|
<!-- 自动扫描 -->
< context:component-scan base-package = "cn.itcast.springmvc.service,cn.itcast.springmvc.web.controller" />
<!-- 注解驱动 -->
< mvc:annotation-driven />

Controller.java 两种形式都可以,但是第二种,jsp页面中的参数是personList1

//列表
@RequestMapping ( "/listAll" )
public String listAll(Map<String,Object> model){
List<Person> personList = ps.listAll();
model.put( "personList" , personList);
System.out.println( " listall hello" );
return "person/jPersonList" ;
}
//列表
@RequestMapping ( "/listAllOther" )
public String listAllOther(Model model){
List<Person> personList1 = ps.listAll();
model.addAttribute(personList1);
System.out.println( " listallother1 hello" );
return "person/jPersonList" ;
}
