Spring MockMvc - How to test delete request of REST controller?
提问by Denis Stephanov
I need to test my controller methods including a delete method. Here is partial controller code:
我需要测试我的控制器方法，包括删除方法。这是部分控制器代码：
@RestController
@RequestMapping("/api/foo")
public class FooController {
@Autowired
private FooService fooService;
// other methods which works fine in tests
@RequestMapping(path="/{id}", method = RequestMethod.DELETE)
public void delete(@PathVariable Long id) {
fooService.delete(id);
}
}
And here is my test:
这是我的测试：
@InjectMocks
private FooController fooController;
@Before
public void setUp() {
this.mockMvc = MockMvcBuilders.standaloneSetup(fooController)
.setControllerAdvice(new ExceptionHandler()).alwaysExpect(MockMvcResultMatchers.content().contentType("application/json;charset=UTF-8")).build();
}
@Test
public void testFooDelete() throws Exception {
this.mockMvc.perform(MockMvcRequestBuilders
.delete("/api/foo")
.param("id", "11")
.contentType(MediaType.APPLICATION_JSON))
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk());
}
Test finish with failure because incorrect status code:
测试完成失败，因为状态代码不正确：
java.lang.AssertionError: Status Expected :200 Actual :400
java.lang.AssertionError：预期状态：200 实际：400
In console log I also found this:
在控制台日志中，我还发现了这一点：
2017-12-11 20:11:01 [main] DEBUG o.s.t.w.s.TestDispatcherServlet - DispatcherServlet with name '' processing DELETE request for [/api/foo]

Can you tell me how to fix it? Thanks.
你能告诉我如何解决吗？谢谢。

Your target URI is: /api/foo/11based on this root: /api/fooand this path variable: /{id}.
您的目标 URI 是：/api/foo/11基于此根：/api/foo和此路径变量：/{id}。
When using MockMvcyou set path variables (aka URI variables) like so:
使用时，MockMvc您可以像这样设置路径变量（又名 URI 变量）：
delete(uri, uriVars)
More details in the Javadocs.
Javadocs 中的更多详细信息。
So, your test should read:
所以，你的测试应该是：
@Test
public void testFooDelete() throws Exception {
this.mockMvc.perform(MockMvcRequestBuilders
.delete("/api/foo/{id}", "11")
.contentType(MediaType.APPLICATION_JSON))
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk());
}
Or alternatively:
或者：
@Test
public void testFooDelete() throws Exception {
this.mockMvc.perform(MockMvcRequestBuilders
.delete("/api/foo/11")
.contentType(MediaType.APPLICATION_JSON))
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk());
}
