Spring Cloud Gateway找不到路由路徑(404錯誤)

[英]Spring Cloud Gateway is not finding a route path (404 error)

我正在研究Spring Cloud Gateway作為用於專業應用程序的API網關解決方案,並且正在本教程中進行操作: http : //spring.io/guides/gs/gateway/#scratch

但是,我遇到了無法解決的問題。

這是我的POM

<groupId>org.springframework</groupId>
<artifactId>gs-gateway</artifactId>
<version>0.1.0</version>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.2.RELEASE</version>
</parent>

            <version>Greenwich.RC2</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>

        <artifactId>spring-cloud-starter-gateway</artifactId>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
    </dependency>

        <artifactId>spring-cloud-starter-contract-stub-runner</artifactId>
        <exclusions>
            <exclusion>
                <artifactId>spring-boot-starter-web</artifactId>
                <groupId>org.springframework.boot</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<properties>
    <java.version>1.8</java.version>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

這是Application.java

@SpringBootApplication
@RestController
public class Application {

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
    return builder.routes()
        .route(p -> p
            .path("/get")
            .filters(f -> f.addRequestHeader("Hello", "World"))
            .uri("http://httpbin.org:80"))
        .build();
}
}

運行此命令並嘗試訪問http:// localhost:8080 / get ,這給了我一個網關超時。 向工作人員咨詢后,我發現自己在防火牆后面,需要代理。 所以我將Application.java修改為:

@SpringBootApplication
@RestController
public class Application {

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
    return builder.routes()
        .route(p -> p.host("internet.proxy.*****.com").and()
            .path("/get")
            .filters(f -> f.addRequestHeader("Hello", "World"))
            .uri("http://httpbin.org:80"))
        .build();
}

現在,我不再讓網關超時,但現在卻遇到404錯誤。 這是使用curl http:// localhost:8080 / get的輸出

{"timestamp":"2019-01- 
    16T14:24:12.929+0000","path":"/get","status":404,"error":"Not 
Found","message":null}

我可能缺少一些簡單的東西,但看不到。

編輯:根據上面列出的教程,這應該是我得到的響應:

{
    "args": {},
    "headers": {
        "Accept": "*/*",
        "Connection": "close",
        "Forwarded": 
         "proto=http;host=\"localhost:8080\";for=\"0:0:0:0:0:0:0:1:56207\"",
        "Hello": "World",
        "Host": "httpbin.org",
        "User-Agent": "curl/7.54.0",
        "X-Forwarded-Host": "localhost:8080"
  },
  "origin": "0:0:0:0:0:0:0:1, 73.68.251.70",
  "url": "http://localhost:8080/get"
}

在代碼中刪除@RestController

您必須將Host標頭設置為“ internet.proxy。*****。com”。

您將主機謂詞和路徑謂詞串聯在一起。

curl --header "Host: internet.proxy.test.com" http://localhost:8080/get
