按照 REST Docs 入门教程，我不幸收到以下错误：

java.lang.IllegalArgumentException: WebApplicationContext is required

对于以下代码：

    @Autowired
    private ObjectMapper objectMapper;

    @Autowired
    private WebApplicationContext context;

    private MockMvc mockMvc;
@Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context)
                .apply(documentationConfiguration(this.restDocumentation))
                .alwaysDo(document("{method-name}/{step}/",
                        preprocessRequest(prettyPrint()),
                        preprocessResponse(prettyPrint())))
                .build();
    }

    @Test
    public void index() throws Exception {
        this.mockMvc.perform(get("/").accept(MediaTypes.HAL_JSON))
                .andExpect(status().isOk())
                .andExpect(jsonPath("_links.business-cases", is(notNullValue())));
    }

我认为依赖注入存在一些问题。但我不确定如何解决它们。你能帮我吗？非常感谢。

您的其余代码在哪里？

java.lang.IllegalArgumentException: WebApplicationContext is required

这意味着您没有创建 Web 应用程序上下文，因此您需要在 web.xml 中或通过 java 配置对其进行配置。

使用java它是这样的：

@Configuration
public class HelloWorldConfig {

   @Bean 
   public HelloWorld helloWorld(){
      return new HelloWorld();
   }
}

使用 XML 和注释，您的 servlet 会加载一个 XML 文件，如下所示：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

   <context:annotation-config/>
   <!-- bean definitions go here -->

</beans>
