Spring 3 MVC控制器集成测试 - 注入Principal方法 [英] Spring 3 MVC Controller integration test - inject Principal into method

问题描述

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

Eg

  @Controller 
 public class MyController {
 
 @RequestMapping（value =/ update，method = RequestMethod。 POST）
 public String update（ModelMap model，Principal principal）{
 
 String name = principal.getName（）; 
 ...其余的
} 
} 
  

作为Spring 3文档的一部分记录在这里：
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。
当我创建一个集成测试（也设置了spring的安全上下文）
并调用控制器句柄方法，那么Principal总是空的！

  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（））; 
 ...设置请求的剩余
 
 ModelAndView mav = handlerAdapter.handle（request，response，controller）; 
 
 ..其余的断言
 
} 
  

任何想法？

解决方案

  request.setUserPrincipal（somePrincipal）; 
  

As part of Spring 3 MVC it is possible to inject the currently logged in user (Principle) object into a controller method.

E.g.

@Controller
public class MyController {

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

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

This is documented as part of the Spring 3 documentation here: http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping-arguments.

This works in the production code. However I don't know how to test this. When I create an integration test (having set up spring security context as well) and call the controller handle method then the Principal is always 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 mav = handlerAdapter.handle(request, response, controller);

    .. rest of assertions

}

The tests are running correctly and everything except the Principal is null.

Any ideas?

解决方案

After a quick look into Spring sources this should work:

request.setUserPrincipal(somePrincipal);
