Question

我是用Java编写RESTFUL代码的新手。 I have followed this tutorial that解释了如何编写RESTFUL程序并返回JSON字符串。这个问题是一个2部分的问题。

现在我想获取Employee名称和其他详细信息，并将其显示在JSP页面上。我该怎么做？

现在，我想传递一个ID并将用户对象返回到视图，我将在JSP文件中显示该对象的详细信息。我怎么能这样做？

@Controller
public class EmployeeController {

private static final Logger logger = LoggerFactory.getLogger(EmployeeController.class);

//Map to store employees, ideally we should use database
Map<Integer, Employee> empData = new HashMap<Integer, Employee>();

@RequestMapping(value = EmpRestURIConstants.DUMMY_EMP, method = RequestMethod.GET)
public @ResponseBody Employee getDummyEmployee() {
    logger.info("Start getDummyEmployee");
    Employee emp = new Employee();
    emp.setId(9999);
    emp.setName("Dummy");
    emp.setCreatedDate(new Date());
    empData.put(9999, emp);
    return emp;
}

@RequestMapping(value = EmpRestURIConstants.GET_EMP, method = RequestMethod.GET)
public @ResponseBody Employee getEmployee(@PathVariable("id") int empId) {
    logger.info("Start getEmployee. ID="+empId);

    return empData.get(empId);
}

在JSP文件中显示REST数据
