Java Jadler : Jetty conflict

Question

我想在我的 Junit 测试中模拟 http 请求。所以我使用 Jadler Project .当我运行我的测试并发送我的 http 请求时，我有这个异常:

java.lang.SecurityException: class "javax.servlet.AsyncContext"'s signer information does not match signer information of other classes in the same package

一开始我的依赖关系看起来像 JAdler 的依赖关系:

<dependency>
    <groupId>net.jadler</groupId>
    <artifactId>jadler-core</artifactId>
    <version>1.1.2</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>net.jadler</groupId>
    <artifactId>jadler-jetty</artifactId>
    <version>1.1.2</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>net.jadler</groupId>
    <artifactId>jadler-junit</artifactId>
    <version>1.1.2</version>
    <scope>test</scope>
</dependency>

经过多次搜索，我明白了为什么会出现这个异常。为了解决它，我不得不像这样更改我的依赖项:

    <dependency>
  <groupId>net.jadler</groupId>
  <artifactId>jadler-core</artifactId>
  <version>1.1.2</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>net.jadler</groupId>
  <artifactId>jadler-jetty</artifactId>
  <version>1.1.2</version>
  <scope>test</scope>
  <exclusions>
    <exclusion>
      <groupId>org.eclipse.jetty</groupId>
      <artifactId>jetty-server</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.eclipse.jetty.orbit</groupId>
      <artifactId>javax.servlet</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-server</artifactId>
  <version>8.1.18.v20150929</version>
  <scope>test</scope>
  <exclusions>
    <exclusion>
      <groupId>org.eclipse.jetty.orbit</groupId>
      <artifactId>javax.servlet</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>net.jadler</groupId>
  <artifactId>jadler-junit</artifactId>
  <version>1.1.2</version>
  <scope>test</scope>
</dependency>

我知道 jetty 不使用 javax.servlet.AsyncContext 的 org.eclipse.jetty.orbit:javax.servlet 但它使用 javax.servlet:javax.servlet-api v3.0.1。

有人知道为什么吗？更好的解决方案？

我的 JDK 版本是 1.6.45。

如果您需要更多信息，例如我的测试资源，请告诉我。

Answer 1

您的依赖树中有两次 servlet-api。

+- javax.servlet:servlet-api:jar:2.4:provided
+- javax.servlet:javax.servlet-api:jar:3.0.1:test

删除 javax.servlet:servlet-api:jar:2.4

然后标记javax.servlet:javax.servlet-api:jar:3.0.1作为<scope>provided</scope>
