spring-mvc

问题 I am working on a Spring-MVC application since some time. Recently I ran into some problems with @Scheduled methods, and I noticed that the whole configuration is getting loaded 4 times.

问题 I'm trying to upgrade a spring MVC app from 3.0.6 to 3.1.2 and some controllers that used to work don't seem to work anymore. I've read the spring docs, but I'm confused about what's compatible with what. We've got a CustomWebArgumentResolver that looks for any request parameter named "asOf" and coverts its value to a date.

问题 Is there any difference between public class Controller1 extends AbstractController { @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { return new AnotherController().handleRequest(request, response); } } and @Controller public class Controller1 { @RequestMapping ... public String handleRequest() { return "forward:/path_to_my_another_controller"; } } 回答1: They're similar, but not quite the same. The second

问题 This works fine until I have to test a service that needs a logged in user, how do I add user to context : @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext-test.xml") @WebAppConfiguration public class FooTest { @Autowired private WebApplicationContext webApplicationContext; private MockMvc mockMvc; @Resource(name = "aService") private AService aService; //uses logged in user @Before public void setup() { this.mockMvc = webAppContextSetup(this

问题 I'm using the new spring-test in the 3.1 version to run integration tests. It works really well but I can't make the session to work. My code: @RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration("src/main/webapp") @ContextConfiguration({"classpath:applicationContext-dataSource.xml", "classpath:applicationContext.xml", "classpath:applicationContext-security-roles.xml", "classpath:applicationContext-security-web.xml", "classpath:applicationContext-web.xml"}) public class SpringTestBase

问题 I am using a Default AnnotationMethodHandlerAdapter which I believe should enable support for @ExceptionHandler. Unluckily, a ServletRequestBindingException is thrown if a call to a handler method like this below is coming in - and not Exception handler is invoked. @RequestMapping(value = "/v1/products/{code}", method = RequestMethod.GET, headers = "Accept=application/xml,application/json") @ResponseBody public ProductDemoDTO getProductByCode(@PathVariable final String code, @RequestParam
