Question

问题是这样的：Spring RESTful Web服务和客户端。当我在服务器上执行DELETE请求时 - ＆GT; DELETE http://localhost:8080/employee/3/logout 405 (Method Not Allowed)

我已经实现了CORS过滤器，但stil不起作用。

EmployeeCotroller

@Controller
@RequestMapping(value = "/employee")
public class EmployeeController {
    private static final EmployeeRepository employeeRepository = new EmployeeRepository();
public EmployeeController(){
}

@RequestMapping(method = RequestMethod.GET, value = "/{employeeId}")
public ResponseEntity<EmployeeDTO> showEmployeeById(@PathVariable int employeeId)
{
    employeeRepository.setEmployeeAsActive(employeeId);
    EmployeeDTO employeeDTO = employeeRepository.getEmployeeDTOForId(employeeId);
    if(employeeDTO != null)
    {
        return new ResponseEntity<EmployeeDTO>(employeeDTO,HttpStatus.OK);
    }
    return new ResponseEntity<EmployeeDTO>(employeeDTO,HttpStatus.NOT_FOUND);
}

@RequestMapping(method = RequestMethod.GET, value = "/{employeeId}/viewTasks")
public ResponseEntity<List<TaskDTO>> showTasksForEmployeeId(@PathVariable int employeeId)
{
    List<TaskDTO> taskDTOs = employeeRepository.getTasksForEmployee(employeeId);
    if(taskDTOs != null)
    {
        return new ResponseEntity<List<TaskDTO>>(taskDTOs, HttpStatus.OK);
    }
    return new ResponseEntity<List<TaskDTO>>(taskDTOs, HttpStatus.NOT_FOUND);
}

@RequestMapping(method = RequestMethod.DELETE, value = "/{employeeId}/logout}")
public ResponseEntity<Void> logoutEmployeeById(@PathVariable int employeeId)
{
    employeeRepository.logoutEmployeeById(employeeId);
    return new ResponseEntity<Void>(HttpStatus.OK);
}

}

我提出请求的地方：

var url = "http://localhost:8080/employee/" + document.cookie1;
$('#employeeLogout').click(function(){
        $.ajax({
           type: "DELETE",
            url: url + "/logout",
            async: true
        });
        document.cookie1 = null;
        window.location.assign('http://localhost:9000/#/employees');
    });

Aaand我的CORS过滤器

    @Component
public class CORSFilter implements Filter {
    //Web container will call a filter when the request was made.
    // CORS filter allows Cross-Origin requests-responses to be performed by adding Access-Controll-Allow-Origin in the header"
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}
}

Answer 1

同样的问题我已经过去并且仍然在努力管理。问题出在Spring Security的某处，因为我的代码在没有安全性的情况下工作正常。但是当启用Spring安全性时，只允许GET，PUT，POST和DELETE不起作用。

Answer 2

作为对此的回应，我的问题是在服务器端使用映射。服务器等待的内容和客户端发送的内容出现问题。我正在发送名称，服务器正在等待用户名。所以这是一个愚蠢的错误:)。如果你得到随机错误，一定要检查愚蠢的错误

405（方法不允许）删除
