Question

在我的控制器测试类中，当我强制抛出一个特定定义的异常时，我试图检查http响应中各种参数的值。但是，我收到以下错误：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.my.exception.myServiceException
    at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:980)
...
Caused by: com.my.exception.myServiceException

myControllerTest.java：

@Test
public void testGetMethodException() throws Exception {
    when(myService.getMethod())
    .thenThrow(myServiceException.class);

     mockMvc.perform(get("/v1/method"))
           .andExpect(MockMvcResultMatchers.jsonPath("$._statusCode")
           .value(HttpStatus.BAD_REQUEST.toString()));

 }

这已经发生在我身上，查看堆栈跟踪，一个模拟对象正在引发NullPointerException，我建议查看堆栈跟踪的结尾。

例如：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException

at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:982)
at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:877)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:661)
at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:851)
at org.springframework.test.web.servlet.TestDispatcherServlet.service(TestDispatcherServlet.java:71)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:742)
...
Caused by: java.lang.NullPointerException
    at java.time.LocalDate.now(LocalDate.java:225)
    at cl.forkchile.api.service.ScheduleService.canBeOpen(ScheduleService.java:24)
...

Spring：控制器的测试处理程序方法：抛出特定的异常，预期嵌套的servlet异常？
