Java 使用Testcontainers与OpenLiberty Server进行集成测试会抛出SocketException

我已经为我的OpenLiberty与MicroProfile应用程序编写了一些集成测试.为了使测试工作，我必须首先执行libertyDev命令.因此，我认为使用Testcontainers是一个好主意，我将try 在其中创建一个OpenLiberty服务器容器，并使用适当的配置文件加载它.在这个范围内，我的测试如下.

    def appUrl

    def setup() {
        openLiberty.start()
        int actualPort = openLiberty.getMappedPort(9080)
        String host = openLiberty.getHost()
        appUrl = "http://$host:$actualPort"

        final String allLogs = openLiberty.getLogs()
        println("Container Logs: \n$allLogs")

        client = HttpClient.newHttpClient()
        jsonb = JsonbBuilder.create()
        requestBody = TestItemProvider.generateRandomItem()
    }

    def 'Successful create item and persist it into JSON, HTML and CSV'() {
        when: 'the call is succeeded'
        def response = doPost(jsonb.toJson(requestBody))

        then: 'empty response body means successful request'
        response.status == Response.Status.CREATED.statusCode
    }

    def 'Failed to create the item'() {
        given: 'an item with null name'
        def requestBody = TestItemProvider.createItemWithNullName()

        when: 'calling the application with this item'
        def response = doPost(jsonb.toJson(requestBody))

        then: 'a response with error message is returned'
        response.status != Response.Status.CREATED.statusCode
        response.readEntity(ErrorResponse.class).errors.size() > 0
    }

    def 'Successfully get an item'() {
        given: 'an item is already created'
        doPost(jsonb.toJson(requestBody))

        when: 'the call is made to the get api'
        def response = doGet()

        then: 'the response contains an OK status'
        response.status == Response.Status.OK.statusCode

        and: 'the response body contains the correct information'
        def returnedItemMap = response.readEntity(List.class)[0]

        returnedItemMap.name == requestBody.name
        returnedItemMap.serialNumber == requestBody.serialNumber
        returnedItemMap.value == requestBody.value
    }

    def 'Successfully delete an item'() {
        given: 'an item is already created'
        doPost(jsonb.toJson(requestBody))

        when: 'the call is made to the delete api'
        def response = doDelete(requestBody.serialNumber)

        then: 'the response contains an OK status'
        response.status == Response.Status.NO_CONTENT.statusCode
    }

    def doPost(Object requestPayload) {
        Client client = ClientBuilder.newClient()
        String targetUrl = "$appUrl/tracking-inventory/inventory"
        return client.target(targetUrl)
                .request(MediaType.APPLICATION_JSON)
                .post(Entity.json(requestPayload))
    }

    def doGet() {
        Client client = ClientBuilder.newClient()
        String targetUrl = "$appUrl/tracking-inventory/inventory"
        return client.target(targetUrl)
                .request(MediaType.APPLICATION_JSON)
                .get()
    }
}

在这里，我挂载了WAR和我的server.xml文件以及各种配置文件.我知道WAR文件被放在Build/libs文件夹中，我会try 在我的build.gradle文件中编写一个类似tests.dependsOn war的任务，以便在测试执行之前正确地生成它.

我的问题是，在运行第一个测试时，我会收到下一个错误:

我try 使用docker run --rm -p 9080:9080 open-liberty:23.0.0.12-full-java17-openj9命令在测试之外运行映像，然后判断http://localhost:9080，它按预期工作.为什么我失go 了与服务器的连接？我遗漏了什么？

推荐答案

我设法解决了这个问题，方法是将server.xml文件中的<httpEndpoint>元素配置为host="*"，具体地说是将host参数配置为host="*".在此之前，我将其设置为host="localhost"，这将通信限制到我的容器.我提供了server.xml以供将来参考:

<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>jakartaee-9.1</feature>
        <feature>microProfile-5.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

    <include location="users.xml" optional="true"/>

    <!-- SSL Config -->
    <ssl id="defaultSSLConfig" trustDefaultCerts="true"/>
    <include location="GeneratedSSLInclude.xml"/>

    <!-- App Config -->
    <httpEndpoint
            host="*"
            httpPort="${default.http.port}"
            httpsPort="${default.https.port}"
            id="defaultHttpEndpoint"/>
    <applicationManager autoExpand="true"/>
    <webApplication
            location="tracking-inventory-0.0.1-SNAPSHOT.war"
            context-root="/">
    </webApplication>
</server>
