Setup Features

无论你使用哪个 MockMvc 构建器，所有 MockMvcBuilder 实现都提供了一些常见且非常有用的功能。例如，你可以声明所有请求的 Accept 标头并期望所有响应中的状态为 200 以及 Content-Type 标头，如下所示：

No matter which MockMvc builder you use, all MockMvcBuilder implementations provide some common and very useful features. For example, you can declare an Accept header for all requests and expect a status of 200 as well as a Content-Type header in all responses, as follows:

Java
Kotlin

// static import of MockMvcBuilders.standaloneSetup

MockMvc mockMvc = standaloneSetup(new MusicController())
	.defaultRequest(get("/").accept(MediaType.APPLICATION_JSON))
	.alwaysExpect(status().isOk())
	.alwaysExpect(content().contentType("application/json;charset=UTF-8"))
	.build();

// Not possible in Kotlin until {kotlin-issues}/KT-22208 is fixed

此外，第三方框架（和应用程序）可以通过预打包设置指令，如 MockMvcConfigurer 中的指令。Spring 框架有一个内置于实现，有助于保存并跨请求重复使用 HTTP 会话。你可以按以下方式使用它：

In addition, third-party frameworks (and applications) can pre-package setup instructions, such as those in a MockMvcConfigurer. The Spring Framework has one such built-in implementation that helps to save and re-use the HTTP session across requests. You can use it as follows:

Java
Kotlin

// static import of SharedHttpSessionConfigurer.sharedHttpSession

MockMvc mockMvc = MockMvcBuilders.standaloneSetup(new TestController())
		.apply(sharedHttpSession())
		.build();

// Use mockMvc to perform requests...

// Not possible in Kotlin until {kotlin-issues}/KT-22208 is fixed
