今天完成的事情
1.完成JSON的简单学习
controller
@Controller
@RequestMapping("")
public class StudentSJsonController {
@Autowired
StudentSService studentSService;
@ResponseBody
@RequestMapping("/submitStudentS")
public String submitStudentS(@RequestBody StudentS studentS){
System.out.println("SSM接受到浏览器提交的json,并转换为StudentS对象："+studentS);
return "OK";
}
@ResponseBody
@RequestMapping("/getOneStudentS")
public String getOneStudentS(){
StudentS c =studentSService.get(2);
c.getId();
c.getName();
c.getAge();
JSONObject json = new JSONObject();
json.put("studentS",JSONObject.toJSON(c));
return json.toJSONString();
}
@ResponseBody
@RequestMapping("/getManyStudentS")
public String getManyStudentS(){
List<StudentS> cs = new ArrayList<StudentS>();
for (int i=0;i <10; i++){
StudentS c=studentSService.get(i);
cs.add(c);
}
return JSONObject.toJSON(cs).toString();
}
}
