使用Wiremock 2.5.1和Spring Boot 1.5.1的ClassNotFoundException

标签： spring-boot wiremock

尝试在Spring Boot 1.5.1.RELEASE和Wiremock 2.5.1中配置测试基础架构时遇到问题。它在扔：

struct fraction {
  int numerator, denominator;
  bool operator<(const fraction& f) const {
    return numerator*f.denominator < f.numerator*denominator;
  }
}

我在另一个项目中使用了Wiremock 2.4.1和Spring Boot 1.3.0.M5，从未遇到过这个问题。

我的测试课程：

我注意到自Spring Boot 1.3.0.M5版本以来，一些测试注释发生了变化，我认为这可能是问题所在。有人有同样的问题吗？

谢谢，

使用spring-boot-dependencies:1.5.2和spring-cloud-dependencies:Dalston.RC1我必须添加以下内容才能让Wiremock正常工作：

...
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Dalston.RC1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>1.5.2</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
</dependencyManagement>

<dependencies>
    ...

    <dependency>
        <groupId>com.github.tomakehurst</groupId>
        <artifactId>wiremock</artifactId>
        <version>2.5.1</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-server</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-servlet</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-servlets</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

如果其他人遇到此问题......

编辑：或者，使用的更简洁的依赖是：

<dependencies>
    ...
    <dependency>
        <groupId>com.github.tomakehurst</groupId>
        <artifactId>wiremock-standalone</artifactId>
        <version>2.6.0</version>
        <scope>test</scope>
    </dependency>
    <!-- Don't need all the jetty and httpclient deps. -->
</dependencies>
...

来自电线公司documentation：

  

目前建议您使用独立JAR作为   与Spring Boot项目的依赖关系。这避免了冲突   Jetty版本。

答案 2 :(得分：2)

我找到了解决方案。

由于某些原因，Maven没有导入jetty依赖项，所以我必须声明它们。他们是：

<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-continuation</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-http</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-io</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-security</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-server</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlet</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlets</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-util</artifactId>
    <scope>test</scope>
</dependency>

如果使用Java 1.8，可以省略Jetty依赖项的版本并使用Wiremock 2.5.1。但如果它是Java 1.7，就像我的一样，我建议使用Wiremock 2.4.1和他的Jetty依赖版本 9.2.13.v20150730 。

我不知道这是否是最好的解决方案，但对我来说就像是一种魅力。希望这有帮助！
