spring - 使用Spring/Jetty(或Tomcat)/Maven为REST测试配置集成测试

Question

我想用HTTP请求测试我们的REST服务(有点黑盒测试)。但是，经过几个小时的谷歌搜索并尝试了不同的配置后，我仍然无法正确启动Jetty。这是我当前的配置(我尝试了多个不同的版本):

pom.xml

        ...

orm.xml

<!-- <context:load-time-weaver/> -->
<context:load-time-weaver weaver-class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
<context:spring-configured/>
<context:annotation-config />
<context:component-scan base-package="com.example.jump.domain">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
</context:component-scan>
    <tx:annotation-driven transaction-manager="transactionManager" />

现在，我遇到了一个异常(exception):

java.lang.IllegalStateException:ClassLoader [org.mortbay.jetty.webapp.WebAppClassLoader]不提供'addTransformer(ClassFileTransformer)'方法。指定一个自定义的LoadTimeWeaver或使用Spring的代理启动Java虚拟机:-javaagent:org.springframework.instrument.jar

我了解异常(exception)情况，但是无法解决。我还尝试了其他几种方法，例如通过MAVEN_OPTS提供javaagent或尝试将VM args设置为Jetty。问题是Google针对不同版本提供了很多“解决方案”，但没有一个在起作用。

我目前非常沮丧，因为在Spring中很难实现像进行REST服务测试这样的常见场景。因此，如果您足够聪明地找到正确的配置，请以一种甚至猴子都可以配置的方式与我分享，我保证如果我们遇见了啤酒就在我身上。

这是我使用的版本:

<properties>
    <java-version>1.6</java-version>
    <org.springframework-version>3.0.5.RELEASE</org.springframework-version>
    <org.aspectj-version>1.6.9</org.aspectj-version>
    <org.slf4j-version>1.5.10</org.slf4j-version>
    <redis.version>1.0.0.BUILD-SNAPSHOT</redis.version>
    <org.jboss.hibernate.version>3.6.0.Final</org.jboss.hibernate.version>
    <net.sf.ehcache.version>2.3.1</net.sf.ehcache.version>
</properties>

Maven的2.21

如果需要，我很乐意提供更多信息。就像我说的，每一个帮助都值得赞赏。

现在，jetty-maven-plugin支持运行分支的目标，您可以在其中传递JVM参数。比使用tomcat装载 cargo 或MAVEN_OPTS容易得多。
