如何将弹簧控制器列表传递给jquery中的ajax

Question

这是我的jquery！在这里，我没有得到成功的响应，而是从列表返回控制器到jquery下面时引发错误响应。请让我知道我哪里错了。

//ajax method to retrieve the data from controller where controller returns list 
function doAjaxPost() { 
    // get the form values 
    var pid = $('#pid').val(); 
    $.ajax({ 
    type: "GET", 
    url: "http://localhost:8085/HMS/iochart1.html", 
    data: "pid=" + pid, 

    success: function (response) { 
     alert(response.list4); 
     $.each(response, function (index, datec) { 
     alert(datec.name); //to print name of employee 
     }); 
    }, 
    // Even though controller returns the list,but i am not getting the above success response,instead below error method is executed. 
    error: function (e) { 
     alert('Error: ' + e); 
    } 
    }); 
} 

下面是返回列表的控制器。

@RequestMapping(value="/iochart1", method = RequestMethod.GET) 
public @ResponseBody List<Iochart> iochart1(@ModelAttribute("s") Iochart s) { 
    System.out.println("Patient"+s.getPid()); 
    List<Iochart> list4 = dao.getPatientdet1(s.getPid()); 
    return list4; 
} 

getPatientdet1（），其从数据库

检索数据

public List<Iochart> getPatientdet1(String pid) { 
    // TODO Auto-generated method stub 
    System.out.println(pid); 
    return template.query(
    "select pid,name,fileno,age,gender,date,wardno,doctord,doctsig,ratef,nursesig,time,type,amount,typecommence,amtgiv,urine,vomitus,remarks from iochart where pid='"+pid+"'", 
    new RowMapper<Iochart>() { 
     public Iochart mapRow(ResultSet rs, int row) throws SQLException { 
     Iochart i = new Iochart(); 
     i.setPid(rs.getString(1)); 
     i.setName(rs.getString(2)); 
     i.setFileno(rs.getString(3)); 
     i.setAge(rs.getString(4)); 
     i.setGender(rs.getString(5)); 
     i.setAdmdate(rs.getString(6)); 
     i.setWardno(rs.getString(7)); 
     i.setDoctord(rs.getString(8)); 
     i.setDoctsig(rs.getString(9)); 
     i.setRatef(rs.getString(10)); 
     i.setNursesig(rs.getString(11)); 
     i.setTime(rs.getString(12)); 
     i.setOraltype(rs.getString(13)); 
     i.setOralamt(rs.getString(14)); 
     i.setOralcommence(rs.getString(15)); 
     i.setAmtgiv(rs.getString(16)); 
     i.setUrine(rs.getString(17)); 
     i.setVomitus(rs.getString(18)); 
     i.setRemarks(rs.getString(19)); 
     System.out.println(rs.getString(2)); 
     return i; 
     } 
     } 
); 
}

变化等所以控制器方法。初衷就是用来获取PID

@RequestMapping(value="/iochart1", method = RequestMethod.GET) 
public @ResponseBody List<Iochart> iochart1(@RequestParam(name = "pid") String pid) { 
    return dao.getPatientdet1(pid); 
} 

的@RequestParam和你一个AJAX网址，像这样

function doAjaxPost() { 
    // get the form values 
    var pid = $('#pid').val(); 
    $.ajax({ 
     type: "GET", 
     url: "http://localhost:8085/HMS/iochart1", //Don't postfix .hmtl 
     data: "pid=" + pid, 
     ... 
    }); 
}
