    user1.setUsername("tom");
    user1.setPassword("汤姆");

    Person user2 = new Person();
    user2.setUsername("john");
    user2.setPassword("约翰");

    userList.add(user1);
    userList.add(user2);

    mm.addAttribute("userList", userList);
    return "userListJson";

<bean id="userListJson"

    p:renderedAttributes="userList" />
