Question

我正在尝试使用Jersey Client来模拟对我的Web服务的HTTP请求。我试图从文档中实现simple example。这是我的简短代码：

public void restoreTest(String sessionId) throws Exception {
    Client client = ClientBuilder.newClient();
    WebTarget target = client.target(idsUrl).path("restore");
    Form form = new Form();
    form.param("sessionId", sessionId);
    target.request(MediaType.APPLICATION_FORM_URLENCODED_TYPE);
}

我甚至没有实现整个示例，因为目前我在最后一行得到了一个例外：

我只将此依赖项添加到我的pom.xml：

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.2</version>
</dependency>

我试图谷歌解决问题，以及调试应用程序，但我真的不明白它有什么问题。

Answer 1

这看起来像是与JAX-RS API版本（包含MultiValuedMap）有关的不一致。

您正在使用客户端jersey-client v2.2，它是针对JAX-RS API的v2.0编译的。但是您的运行时声明要使用Java EE 6运行，它定义了JAX-RS API v1.1。因此，您的代码需要JAX-RS API的v2.0，但在运行时获得v1.1。

这是Java EE 6的MultiValuedMap API：

http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/MultivaluedMap.html（没有addAll方法）。

对于Java EE 7：

http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/MultivaluedMap.html（这个包含addAll方法）。

当您使用Java EE 6时，您应该使用jersey-client v1.8，而不是2.2。或者您应该在运行时类路径中包含Java EE 7 API，而不是6。

Answer 2

违规类来自此依赖

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

里面有jax-rs 1.1核心类，特别是没有MultivaluedMap方法的addAll接口。

禁用它（如果只使用Jersey，似乎可以），或升级到version到7.0

Answer 3

在我的情况下，这看起来与Jersey Client和Jersey Core存在不兼容问题。我通过禁用客户端来解决它：
