我正在尝试使用 Jersey 客户端来模拟对我的 Web 服务的 HTTP 请求。我试图实现 simple example从文档中。这是我的短代码:

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);
}

我什至没有实现整个示例，因为目前我在最后一行遇到异常:

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>

我尝试用谷歌搜索问题，并调试应用程序，但我真的看不出它有什么问题。

最佳答案

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。但是您的运行时状态可以使用定义 JAX-RS API v1.1 的 Java EE 6 运行。因此，您的代码需要 v2.0 的 JAX-RS API，但在运行时获取 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 (这个包括 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。
