With the below code I have converted list to json but the format is as 
 follows:

```
{"GodownMaster":[{"pname":"FCI CHARLAPALLI","pcode":"16042"},
{"pname":"MLS CIRCLE 1 L.B. NAGAR","pcode":"16016"},{"pname":"MLS CIRCLE 4 
AZAMABAD","pcode":"16003"},{"pname":"MLS CIRCLE 6 
VIDYANAGAR","pcode":"16005"},{"pname":"OTHERS","pcode":"1699"}]} 

```

---

but I want to convert it as : 

```
[{"pname":"FCI CHARLAPALLI","pcode":"16042"},
{"pname":"MLS CIRCLE 1 L.B. NAGAR","pcode":"16016"},{"pname":"MLS CIRCLE 4 
AZAMABAD","pcode":"16003"},{"pname":"MLS CIRCLE 6 
VIDYANAGAR","pcode":"16005"},{"pname":"OTHERS","pcode":"1699"}] 

```

Below is my spring controller : 

```
@RequestMapping("/getGodowns")
public @ResponseBody Map 
getGodownsBasedOnDistrict(@RequestParam(value="district_code") String 
dist_code) {

List<CscGodownBean> godown_list = null;
Map<String, List<CscGodownBean>> m = new HashMap();
String exception = null;
try
{
//getting name and codes here
godown_list = scm_service.getGodownListBesedOnDistCode(dist_code);
}catch(Exception ex)
{
ex.printStackTrace();
exception = ex.getMessage();
}

if(godown_list!=null) {
for(int i=0;i<godown_list.size();i++) {
m.put("GodownMaster",godown_list);
}
}
return m;
}

```
