Question

我有一个Spring Controller，

@Controller
@RequestMapping(value = "/employee")
public class EmployeeController {

@Autowired
private EmployeeService employeeService;

/**
 * returns all the employees in the datastore.
 * 
 * @return list of all employees.
 */
@RequestMapping(method = RequestMethod.GET)
public @ResponseBody String getAllEmployees() {
    return convertObjectListToJSONArray(this.employeeService.listEmployees());
}

/**
 * adds an employee in the data-store.
 * 
 * @param employee
 *            employee to add in the data-store.
 * @return request status.
 */
@ResponseStatus(value = HttpStatus.CREATED)
@RequestMapping(method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
public ResponseEntity<?> addEmployee(UriComponentsBuilder uriCBuilder, @RequestBody Employee employee) {
    Employee e = this.employeeService.getEmployeeById(employee.getId());
    if(null != e) {
        throw new EmployeeConflictException(); 
    }
    this.employeeService.addEmployee(employee);
    UriComponents uriComponents = uriCBuilder.path("/cmpe281Pratik021/rest/employee/{id}")
            .buildAndExpand(employee.getId());
    HttpHeaders headers = new HttpHeaders();
    headers.setLocation(uriComponents.toUri());
    return new ResponseEntity<Void>(headers, HttpStatus.CREATED);
}

但是，当我点击http://localhost:8080/employee时，它会给出错误404。有没有办法打印到将要映射此Spring控制器的完整URL？

Answer 1

有没有办法打印到这个Spring控制器的完整URL 要映射？

您可以启用以下日志记录属性：

log4j.category.org.springframework.web=INFO

现在，如果重新启动Tomcat（或任何服务器），那么在启动期间，当Spring容器初始化DispactherServlet和HandlerMapping时，它将打印所有已识别的映射（来自各种{ {1}}类）到日志中，以便您可以实际验证Controller类将为哪些映射提供服务。

P.S。：此日志记录只是列出/记录所有控制器映射，这将有助于调试/解决问题

有没有办法知道Spring控制器要映射哪个完整的URL？
