我正在使用 spring MVC 测试:在我的测试用例中,我传递了一个无效的 Bar
对象(年龄为零)。正在抛出 MethodArgumentNotValidException
,但它嵌套在 NestedServletException
中。是否有通过现有/自定义 HandlerExceptionResolver
从 Controller 中抛出 MethodArgumentNotValidException
异常,以便我当前的测试用例 checkHit2
通过?
Controller :
@RequestMapping(value="/test", method = RequestMethod.POST, headers="Accept=application/json")
@ResponseBody
public Bar getTables(@Valid @RequestBody Bar id) {
return id;
}
测试用例
@Before
public void setUp() {
mockMvc = standaloneSetup(excelFileUploader).setHandlerExceptionResolvers(new SimpleMappingExceptionResolver()).build();
}
@Test(expected=MethodArgumentNotValidException.class)
public void checkHit2() throws Exception {
Bar b = new Bar(0, "Sfd");
mockMvc.perform(
post("/excel/tablesDetail").contentType(
MediaType.APPLICATION_JSON).content(
TestUtil.convertObjectToJsonBytes(b)));
栏
public class Bar {
@JsonProperty("age")
@Min(value =1)
private int age;
public Bar(int age, String name) {
super();
this.age = age;
this.name = name;
}
...
}
Junit 输出
java.lang.Exception: Unexpected exception,
expected<org.springframework.web.bind.MethodArgumentNotValidException> but
was<org.springframework.web.util.NestedServletException>
最佳答案
我有类似的问题,我修复了它从 NestedServletException 扩展我的异常类。例如:
@RequestMapping(value = "/updateForm/{roleID}", method = RequestMethod.GET)
public String updateForm(@PathVariable Long roleID, Model model, HttpSession session) throws ElementNotFoundException {
Role role = roleService.findOne(roleID);
if (role == null) {
throw new ElementNotFoundException("Role");
}
...
}
我的异常看起来像:
public class ElementNotFoundException extends NestedServletException {
private static final long serialVersionUID = 2689075086409560459L;
private String typeElement;
public ElementNotFoundException(String typeElement) {
super(typeElement);
this.typeElement = typeElement;
}
public String getTypeElement() {
return typeElement;
}
}
所以我的测试是:
@Test(expected = ElementNotFoundException.class)
public void updateForm_elementNotFound_Test() throws Exception {
String roleID = "1";
Mockito.when(roleService.findOne(Long.valueOf(roleID))).thenReturn(null);
mockMvc.perform(get("/role/updateForm/" + roleID)).andExpect(status().isOk()).andExpect(view().name("exception/elementNotFound"));
}
关于java - 在 Junit 测试用例中处理 MethodArgumentNotValidException?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/21620964/
