如何從springMVC中返回JSON對象的列表？

Question

我怎樣才能返回像{「項目」：「[」{「」：「」}，{「」：「」，...「]」}形式的Spring MVC3.0的json對象列表？請對此有所幫助...

Answer 1

@RequestMapping(value="/list", method=RequestMethod.GET)//, headers=ACCEPT_JSON) 
@ResponseBody 
public List<User> userList() { 
    LOG.info("get list of Users"); 

    List<User> users = new ArrayList<User>(); 
    users.add(new User("user1", "pass1", "name1", Boolean.TRUE)); 
    users.add(new User("user2", "pass2", "name2", Boolean.TRUE)); 
    users.add(new User("user3", "pass3", "name3", Boolean.TRUE)); 

    return users; 
}
