作为Spring 3 MVC的一部分,可以将当前登录的用户(Principle)对象注入控制器方法.

例如

@Controller
public class MyController {

    @RequestMapping(value="/update", method = RequestMethod.POST)
    public String update(ModelMap model, Principal principal) {

       String name = principal.getName();
       ... the rest here
    }
}

这是作为Spring 3文档的一部分记录的:http: //static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping-arguments.

这适用于生产代码.但是我不知道如何测试这个.当我创建集成测试(也设置了spring安全上下文)并调用控制器句柄方法时,Principal始终为null!

public class FareTypeControllerIntegrationTest extends SpringTestBase {

@Autowired
private MyController controller;

@Autowired
private AnnotationMethodHandlerAdapter handlerAdapter;

private final MockHttpServletRequest request = new MockHttpServletRequest();
private final MockHttpServletResponse response = new MockHttpServletResponse();

@Test
public void testUpdate() throws Exception {
    request.setRequestURI("/update");
    request.setMethod(HttpMethod.POST.name());
    ... setup rest of request

    ModelAndView …
