Java 如何在筛选器中修改post调用的对象。弹簧靴

我的应用程序中有一个过滤器

@Component
@Order(2)
public class RequestResponseLoggingFilter implements Filter {

    @Override
    public void doFilter(
      ServletRequest request, 
      ServletResponse response, 
      FilterChain chain) throws IOException, ServletException {

        HttpServletRequest req = (HttpServletRequest) request;
        HttpServletResponse res = (HttpServletResponse) response;
        // SET VALUE OF OBJECT
    }

    // other methods
}

我有一个使用类的Restcall

@RequestMapping
Class Test{
  @PostMapping("/test")
  public void postEntry(@Valid @RequestBody Testing testing){
  }
}

Class Testing{
@NotNull(message="ERROR")  
String id;

....
}

我在我的过滤器中获得id，我想在我的过滤器中设置测试类的id。这可能吗？

您可以使用类似的

MockHttpServletRequest

方法

@Test
public void testAddEventWithWebAuthenticationDetails() {
    HttpSession session = new MockHttpSession(null, "test-session-id");
    MockHttpServletRequest request = new MockHttpServletRequest();
    request.setSession(session);
    request.setRemoteAddr("1.2.3.4");
    WebAuthenticationDetails details = new WebAuthenticationDetails(request);
    Map<String, Object> data = new HashMap<>();
    data.put("test-key", details);
    AuditEvent event = new AuditEvent("test-user", "test-type", data);
    customAuditEventRepository.add(event);
    List<PersistentAuditEvent> persistentAuditEvents = persistenceAuditEventRepository.findAll();
    assertThat(persistentAuditEvents).hasSize(1);
    PersistentAuditEvent persistentAuditEvent = persistentAuditEvents.get(0);
    assertThat(persistentAuditEvent.getData().get("remoteAddress")).isEqualTo("1.2.3.4");
    assertThat(persistentAuditEvent.getData().get("sessionId")).isEqualTo("test-session-id");
}

过滤类

public class MyFilter implements Filter {
  @Override
  public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {

    /* wrap the request in order to read the inputstream multiple times */
    MultiReadHttpServletRequest multiReadRequest = new MultiReadHttpServletRequest((HttpServletRequest) request);

    doMyThing(multiReadRequest.getInputStream());
    chain.doFilter(multiReadRequest, response);
  }
}

谢谢你，这非常有帮助

public class MyFilter implements Filter {
  @Override
  public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {

    /* wrap the request in order to read the inputstream multiple times */
    MultiReadHttpServletRequest multiReadRequest = new MultiReadHttpServletRequest((HttpServletRequest) request);

    doMyThing(multiReadRequest.getInputStream());
    chain.doFilter(multiReadRequest, response);
  }
}
