【问题描述】：

我正在使用jackson pojo mapping 创建jersey rest 客户端。这是代码spinet：

    ClientConfig clientConfig = new DefaultClientConfig();
    clientConfig.getClasses().add(JacksonJsonProvider.class);
    clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
    client = Client.create(clientConfig);
    webResource = client.resource("url to exposed rest web service");

此代码在client = Client.create(clientConfig) 行抛出以下异常

我正在使用以下罐子：

杰克逊核心 asl:1.9.13
杰克逊贾克斯：1.9.13
杰克逊-xc：1.9.13
jersey-client:1.1.5.1

我厌倦了搜索google and stackoverflow，但找不到任何解决方案。如果有人遇到同样的错误并解决了问题，请提出一些解决方案。

【问题讨论】：

请格式化您问题中的代码

标签： java json rest jersey

【解决方案1】：

我得到了问题的解决方案。这是由于 jar 冲突。我将 jersey-client:1.1.5.1 更改为 jersey-client:1.18
