使用RestAssuredMockMvc时没有这样的方法错误

Question

我正在使用RestAssuredMockMvc进行弹簧mvc控制器的单元测试。这是我的代码：

import com.xyz.api.controller.UserController;
import com.jayway.restassured.module.mockmvc.RestAssuredMockMvc;
import org.junit.Before;
import org.junit.Test;

import javax.servlet.http.HttpServletResponse;

import static org.hamcrest.Matchers.equalTo;

public class UserControllerRest {

    private String userName = "[email protected]";
    private String expectedResult = "Hello " + userName;

    @Before
    public void initialize() {
        RestAssuredMockMvc.standaloneSetup(new UserController());
    }

    @Test
    public void checkResponseAndBody() throws Exception {
        RestAssuredMockMvc.given().param("userName", userName).when().get("/users").print();
        RestAssuredMockMvc.given().param("userName", userName).when().get("/users").then().assertThat().statusCode(200).and().body(equalTo(expectedResult));
    }
}

checkResponseAndBody()中的第一个语句打印：Hello [email protected]但第二行给出以下错误：

java.lang.NoSuchMethodError: com.jayway.restassured.internal.ValidatableResponseOptionsImpl.<init>(Ljava/lang/String;Lcom/jayway/restassured/internal/ResponseParserRegistrar;Lcom/jayway/restassured/config/RestAssuredConfig;Lcom/jayway/restassured/response/Response;Lcom/jayway/restassured/response/ExtractableResponse;)V

我已经看过这些示例，甚至尝试使用相同的代码，但仍然存在错误。我怎么解决这个问题？

Answer 1

您可能没有将所有依赖项添加到类路径中。如download页面所示，您还需要下载并将rest-assured-2.5.0-dist.zip的内容放入类路径中。

如果你正在使用Maven，它应该足以依赖于spring-mock-mvc模块：

<dependency>
      <groupId>com.jayway.restassured</groupId>
      <artifactId>spring-mock-mvc</artifactId>
      <version>${rest-assured.version}</version>
      <scope>test</scope>
</dependency>

或者是gradle：

testCompile "com.jayway.restassured:spring-mock-mvc:${rest-assured.version}"

Answer 2

当我使用Maven放心时，发生了这种情况（令人惊讶的是，Gradle没有给我这个问题，它与Maven不同，它处理得很好）。

对我来说，这是一种依赖冲突。我在我的pom.xml中将Apache Phoenix作为依赖项

    <groupId>org.apache.phoenix</groupId>
    <artifactId>phoenix</artifactId>
    <version>4.13.2-cdh5.11.2</version>

这个Apache Phoenix jar依赖于httpclient version 4.0.1 jar，它覆盖了我的restassured jar依赖的版本（这是httpclient version 4.3.5）。 Maven默认排除了后来的版本（4.5.3）。为了解决这个问题，我在Apache Phoenix pom部分的旧版本中添加了exclusion，如下所示：

            <dependency>

              <groupId>org.apache.phoenix</groupId>
              <artifactId>phoenix-core</artifactId>
              <version>4.13.2-cdh5.11.2</version>

              <exclusions>
                <exclusion>
                   <groupId>org.apache.httpcomponents</groupId>
                   <artifactId>httpclient</artifactId>
                </exclusion>
              </exclusions>

          </dependency>

这样，我的httpclient罐子里的restassured版本取代了，一切正常。
