放心 + 模拟 MVC @ControllerAdvice

问题描述

在我的项目中，我使用具有以下依赖项的 Rest Assured MockMVC:

In my project I am using Rest Assured MockMVC with the following dependency:

<dependency>
    <groupId>com.jayway.restassured</groupId>
    <artifactId>spring-mock-mvc</artifactId>
    <version>2.9.0</version>
</dependency>

我的测试类看起来像:

TestController testController = new TestController();
@Before
public void configureRestAssuredForController() {
    RestAssuredMockMvc.standaloneSetup(testController);
}

我在控制器类中定义了几个 ExceptionHandler.在我的 JUnit 测试中，我可以验证在控制器类中定义的请求路径和处理程序.

I have a couple of ExceptionHandlers defined in the controller class.In my JUnit tests I could verify the request paths and the handlers when defined in the controller class.

但是 - 当我使用 @ControllerAdvice 将处理程序移动到一个单独的类时，处理程序不会从测试中调用.

However - When I moved the handlers to a separate class with @ControllerAdvice, handlers are not being invoked from the tests.

我知道这是因为控制器的独立设置，可能无法加载在另一个类中定义的处理程序.

I understood that it is because of the standalone set up for the controller,which probably could not load handlers defined in another class.

但我不知道如何在独立模式下将异常处理程序添加到 RestAssuredMockMvc 以使其工作.

But I couldn't figure out how do I add the exception handlers to the RestAssuredMockMvc,in standalone mode to make this work.

我正在挣扎，非常感谢您的帮助.

I am struggling and any help is much appreciated please.

推荐答案

基于这个答案，我创建了一个对我有用的解决方案:

Based on this answer I've created a solution that works great for me:

/**
 * Initializes GlobalExceptionHandler advice using the StaticApplicationContext with the single bean.
 *
 * @return HandlerExceptionResolver instantiated based on the GlobalExceptionHandler
 */
private HandlerExceptionResolver initGlobalExceptionHandlerResolvers() {
    StaticApplicationContext applicationContext = new StaticApplicationContext();
    applicationContext.registerSingleton("exceptionHandler", GlobalExceptionHandler.class);

    WebMvcConfigurationSupport webMvcConfigurationSupport = new WebMvcConfigurationSupport();
    webMvcConfigurationSupport.setApplicationContext(applicationContext);

    return webMvcConfigurationSupport.handlerExceptionResolver();
}

@Before
public void setup() {
    HandlerExceptionResolver handlerExceptionResolver = initGlobalExceptionHandlerResolvers();

    RestAssuredMockMvc.standaloneSetup(
            MockMvcBuilders
                    .standaloneSetup(controller)
                    .setHandlerExceptionResolvers(handlerExceptionResolver)
    );
}

所以我的 GlobalExceptionHandler 是使用 StaticApplicationContext 初始化的，然后我从中检索 handlerExceptionResolver 并将其传递给 RestAssuredMockMvc standaloneSetup

So my GlobalExceptionHandler is initialized using StaticApplicationContext and then I retrieve handlerExceptionResolver from it and pass it into RestAssuredMockMvc standaloneSetup
