A Microservice Architecture with Spring Boot and Spring Cloud（五）

测试 REST API

最后，我们将测试我们的REST API。

首先，一个简单的设置：

private final String ROOT_URI = "http://localhost:8080";

private FormAuthConfig formConfig  = new FormAuthConfig("/login", "username", "password");

@Before public void setup() {    
    RestAssured.config = config().redirect(RedirectConfig.redirectConfig().followRedirects(false)); }

接下来，让我们得到所有books：

@Test 
public void whenGetAllBooks_thenSuccess() {    
    Response response = RestAssured.get(ROOT_URI + "/book-service/books");
    Assert.assertEquals(HttpStatus.OK.value(), response.getStatusCode());  
    Assert.assertNotNull(response.getBody()); 
}

然后，尝试不登录来访问受保护的资源：

@Test 
public void whenAccessProtectedResourceWithoutLogin_thenRedirectToLogin() {    
    Response response = RestAssured.get(ROOT_URI + "/book-service/books/1");
    Assert.assertEquals(HttpStatus.FOUND.value(), response.getStatusCode()); 
    Assert.assertEquals("http://localhost:8080/login",response.getHeader("Location")); 
}

然后，登录并创建新的book对象：

@Test 
public void whenAddNewBook_thenSuccess() {    
    Book book = new Book("Baeldung", "How to spring cloud");    
    Response bookResponse = RestAssured.given().auth()
        .form("admin", "admin", formConfig).and()      
        .body(book)      
    Book result = bookResponse.as(Book.class);
    Assert.assertEquals(HttpStatus.OK.value(), bookResponse.getStatusCode()); 
    Assert.assertEquals(book.getAuthor(), result.getAuthor());   
}

然后在身份验证后访问受保护的资源：

@Test 
public void whenAccessProtectedResourceAfterLogin_thenSuccess() {    
    Response response = RestAssured.given().auth()      
        .form("user", "password", formConfig)      
        .get(ROOT_URI + "/book-service/books/1");
    Assert.assertEquals(HttpStatus.OK.value(), response.getStatusCode());    
 }

现在，我们将创建新的Rating对象：

@Test 
public void whenAddNewRating_thenSuccess() {    
    Rating rating = new Rating(1L, 4);    
    Response ratingResponse = RestAssured.given().auth()      
        .form("admin", "admin", formConfig).and()      
        .contentType(ContentType.JSON)      
        .body(rating)      
    Rating result = ratingResponse.as(Rating.class);
    Assert.assertEquals(HttpStatus.OK.value(), ratingResponse.getStatusCode());   
    Assert.assertEquals(rating.getBookId(), result.getBookId());    
}

现在尝试访问管理员保护的Rating资源：

@Test 
public void whenAccessAdminProtectedResource_thenForbidden() {    
    Response response = RestAssured.given().auth()      
        .form("user", "password", formConfig)      
        .get(ROOT_URI + "/rating-service/ratings");
}

通过使用admin登录访问受保护的Rating

@Test 
public void whenAdminAccessProtectedResource_thenSuccess() {  
    Response response = RestAssured.given().auth()      
        .form("admin", "admin", formConfig)      
        .get(ROOT_URI + "/rating-service/ratings");
    Assert.assertEquals(HttpStatus.OK.value(), 
    response.getStatusCode()); 
    Assert.assertNotNull(response.getBody()); 
}

最后，以管理员身份访问discovery资源：

@Test 
public void whenAdminAccessDiscoveryResource_thenSuccess() { 
    Response response = RestAssured.given().auth() 
        .form("admin", "admin", formConfig)      
        .get(ROOT_URI + "/discovery");  
    Assert.assertEquals(HttpStatus.OK.value(),response.getStatusCode()); }

运行

• 首先，在您的HOME目录中创建一个本地Git存储库application-config。
• 添加配置属性文件。
• 确保在运行服务之前提交本地Git存储库中的所有更改。

git add -A
git commit -m "the initial configuration"

• 确保按以下顺序运行模块：
• 在端口8081运行配置服务
• 接着，在端口8082运行发现服务
• 之后，在端口端口8080运行网关服务
• 最后，分别在端口8083和8084运行资源服务

结论

我们已经完成了 - 使用Spring Boot构建的全功能微服务架构Spring Cloud。
GitHub上提供了所有模块的源代码。
