service():
public class UserServiceImpl implements UserService {
private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public List<User> getAll() {
return userDao.getAll();
}
jsp:
<script type="text/javascript">
$(document).ready(function(){
$("#bt").click(function(){
$.post(url,data,calback);
});
});
</script>
</head>
<body>
<a href="user_getAll.action">${count}人！</a>
<br>
<button type="button" id="bt">
本页加载
</button>
<div id="content">
</div>
</body>
加个Controller层，把service注进来。
e.g.【springmvc】
@RequestMapping(value = "test/test.do", method = RequestMethod.GET)
public String testMethod(HttpServletRequest request,
HttpServletResponse response)
throws WebControllerException {
// service.XXX;
}
jsp
$.get("XXXXX/test/test.do?param=1", function(data) {
});
大概这样
public List getAll() {
return userDao.getAll();
}
把你的返回值改成json格式，前台解析json来显示。
后台封装成json
前台
$.post("XXXXX/test/test.do,{parm1:LZ,parm2:SB}, function(data) {
},"json");
