当我从 JUnit 测试用例向 Rest Service 发送请求时，我收到 400 Bad Request。PFB 我的代码。错误日志接近尾声。请帮助我解决问题。当我将服务器调用为：restTemplate.getForObject(BASE_URL + "/remote?serviceName=simpleService&source=WEB", HelloWorld.class) 通过直接在 URL 中传递参数时，我没有收到任何错误。但是如何使用地图通过，这就是问题所在。

我的控制器：

@Controller
@RequestMapping("/remote")

public class RESTController implements IController{

@RequestMapping(method = RequestMethod.GET, headers = "Accept=application/xml,  application/json")
public @ResponseBody HelloWorld getMessage(@RequestParam("serviceName") String serviceName, @RequestParam("source") String source) throws ApplicationException{
    System.out.println("got the request:");
    serviceLocator serviceLocator = new serviceLocator();
    HelloWorld helloWorld = new HelloWorld();
    helloWorld.setMessage(serviceLocator.getMessage(serviceName));
    return helloWorld;
}

我的配置：

<context:annotation-config />

<context:component-scan base-package="com" />

<mvc:annotation-driven />

<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
            <bean
                class="org.springframework.http.converter.StringHttpMessageConverter" />
            <bean id="jsonViewResolver"
                class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="objectMapper" ref="JacksonObjectMapper" />
                <property name="supportedMediaTypes">
                    <list>
                        <bean class="org.springframework.http.MediaType">
                            <constructor-arg value="application" />
                            <constructor-arg value="json" />
                            <constructor-arg
                                value="#{T(java.nio.charset.Charset).forName('UTF-8')}" />
                        </bean>
                    </list>
                </property>
            </bean>

        </list>
    </property>
</bean>
<bean id="JacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper" />

我的控制器测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("applicationContextTest.xml")
public class RESTControllerTest {

private static final String BASE_URL = "http://localhost:8080/SimpleServiceWeb/rest";

@Autowired
private RestTemplate restTemplate;

@Test
public void getMessage() throws Exception { 

    String expected = "Hello Spring!";
    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setAccept(Collections
            .singletonList(MediaType.APPLICATION_XML));     

    MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
    map.add("serviceName", "simpleService");
    map.add("source", "WEB");

    ObjectMapper mapper = new ObjectMapper();
    ObjectWriter normalWriter = mapper.writer();
    String jsonString = normalWriter.writeValueAsString(map);;
    HttpEntity<Object> requestEntity = new HttpEntity<Object>(httpHeaders);     

    HelloWorld helloWorld = restTemplate.exchange(BASE_URL + "/remote",
             HttpMethod.GET, requestEntity, HelloWorld.class, map) .getBody();

    assertThat(helloWorld.getMessage(), is(expected));
}

}

  1. 您的控制器接受 application/xml 和 application/json 类型。
  2. 只有在 messageConverters 中配置的 JSON 转换器，我没有看到任何 XML 转换器。
  3. 在测试用例中，您将媒体类型设置为 application/xml。

可能是由于缺少 xml 转换器，Spring 无法适当地编组您的请求并因此给出 400？尽管如控制器中所述，支持媒体类型，这就是您没有获得 415 的原因。
