限时送ChatGPT账号..控制器
@RestController
@Validated
class MyController {
@GetMapping("/foo")
public String unwrapped(@Min(1) @RequestParam("param") int param) {
return Integer.toString(param);
}
@GetMapping("/bar")
public String wrapped(@ModelAttribute @Valid Wrapper bean) {
return Integer.toString(bean.param);
}
static class Wrapper {
@Min(1)
int param;
public void setParam(final int param) {
this.param = param;
}
}
}
测试
public class MyControllerTest {
MyController controller = new MyController();
MockMvc mockMvc = MockMvcBuilders
.standaloneSetup(this.controller)
.build();
@Test // fails
public void unwrapped() throws Exception {
this.mockMvc.perform(get("/foo")
.param("param", "0"))
.andExpect(status().isBadRequest());
}
@Test // passes
public void wrapped() throws Exception {
this.mockMvc.perform(get("/bar")
.param("param", "0"))
.andExpect(status().isBadRequest());
}
}
要在 spring 中启用(解包)方法参数验证,必须使用 @Validated
注释控制器,并且必须将 MethodValidationPostProcessor
添加到上下文中.
是否可以将 MethodValidationPostProcessor
bean 添加到独立设置中?
问题可能会简化为如何将 BeanPostProcessor
添加到独立的 MockMvc 设置中?
To enable (unwrapped) method parameter validation in spring the controller has to be annotated with @Validated
and the MethodValidationPostProcessor
must be added to the context.
Is it possible to add the MethodValidationPostProcessor
bean to the standalone setup ?
The question might be reduced to how to add a BeanPostProcessor
to a standalone MockMvc setup ?
推荐答案
是否可以将
MethodValidationPostProcessor
bean 添加到独立设置中?
Is it possible to add the
MethodValidationPostProcessor
bean to the standalone setup ?
不,不幸的是,在使用 MockMvcBuilders.standaloneSetup()
时这是不可能的,因为这会在幕后创建一个 StubWebApplicationContext
而不支持BeanPostProcessor
s.
No, that is unfortunately not possible when using MockMvcBuilders.standaloneSetup()
since that creates a StubWebApplicationContext
behind the scenes which does not support BeanPostProcessor
s.
一旦 SPR-6380 得到解决(目前在 Spring Framework 5.x 中).x backlog),您将不再需要依赖 MethodValidationPostProcessor
.但是,在此期间,您需要切换到使用 MockMvcBuilders.webAppContextSetup()
以便能够测试通过 MethodValidationPostProcessor
添加到您的控制器的行为.
Once SPR-6380 has been addressed (currently in the Spring Framework 5.x backlog), you will no longer need to rely on the MethodValidationPostProcessor
. However, in the interim you will need to switch to the use of MockMvcBuilders.webAppContextSetup()
in order to be able to test the behavior added to you controller via MethodValidationPostProcessor
.
我认为不可能直接做到这一点;但是,您可以创建 StandaloneMockMvcBuilder
的自定义子类,该子类覆盖 initWebAppContext()
方法,委托给 super.initWebAppContext()
以创建 WebApplicationContext
,然后通过org.springframework.test.web.servlet.setup.StubWebApplicationContext.addBean(String, Object)
以编程方式注册MethodValidationPostProcessor
bean.
I don't think it's possible to do that directly; however, you could create a custom subclass of StandaloneMockMvcBuilder
that overrides the initWebAppContext()
method, delegates to super.initWebAppContext()
to create the WebApplicationContext
, and then registers the MethodValidationPostProcessor
bean programmatically via org.springframework.test.web.servlet.setup.StubWebApplicationContext.addBean(String, Object)
.
