@ModelAttribute也可以做为Model输出到View时使用，比如：
测试例子
package com.my.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.my.controller.bean.Account;
@Controller
@RequestMapping(value="attr")
public class TestModelAttributeController {
private static List<Account> accounts = new ArrayList<Account>();
{
accounts.add(new Account());
accounts.add(new Account());
Account ac1 = accounts.get(0);
Account ac2 = accounts.get(1);
ac1.setUserName("Robin");
ac1.setPassword("123123");
ac2.setUserName("Lucy");
ac2.setPassword("123456");
}
@RequestMapping(method=RequestMethod.GET)
public String index() {
System.out.println("index");
return "TestModelAttribute/index";
}
@ModelAttribute("accounts")
public List<Account> getAccounts() {
System.out.println("getAccounts");
return accounts;
}
}

页面将输出：
在Console中输出为：
这里可以看到，运行的先后次序为：先调用getAccounts()，再调用index()。
