java - 如何使用放心调用web服务

Question

我是新手请放心，我在使用它运行基本程序时遇到了麻烦。我刚刚创建了一个Java项目并添加了所需的放心jar。 下面是我的简单代码:

import com.jayway.restassured.RestAssured;
import com.jayway.restassured.RestAssured.*;
import com.jayway.restassured.matcher.RestAssuredMatchers.*;
import org.hamcrest.Matchers.*;

public class RestServiceTest 
{

    public static void main(String args[]) throws Exception
    {
//        RestAssured.baseURI="http://restcountries.eu/rest/v1/";

          String str=RestAssured.get("http://restcountries.eu/rest/v1/name/Norway").asString();
          System.out.println(str);


    }
}

我还添加了一个 pom.xml 文件来添加以下依赖项。

<dependency>
  <groupId>com.sun.jersey.jersey-test-framework</groupId>
  <artifactId>jersey-test-framework-core</artifactId>
  <version>1.9</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>com.sun.jersey.jersey-test-framework</groupId>
  <artifactId>jersey-test-framework-external</artifactId>
  <version>1.9</version>
</dependency>

当我运行上面的代码时，我遇到了异常:

有人可以帮助我创建一个 maven 项目还是简单的 java 项目并添加 pom.xml 文件？

我已经将 maven 添加到环境变量中。

Answer 1

您需要创建一个maven项目并在pom.xml文件中添加依赖并构建maven项目。

您需要添加的其他依赖项:

<dependency>
    <groupId>com.jayway.restassured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>2.5.0</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5</version>
</dependency>
