java.lang.NoSuchFieldError:创建球衣其余客户端时出现WADL_JSON [英] java.lang.NoSuchFieldError: WADL_JSON in creating jersey rest client

问题描述

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

I am creating jersey rest client with jackson pojo mapping. here is code 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)

我正在使用以下罐子:

jackson-core-asl:1.9.13
jackson-jaxrs:1.9.13
jackson-xc:1.9.13
jersey-client:1.1.5.1

jackson-core-asl:1.9.13
jackson-jaxrs:1.9.13
jackson-xc:1.9.13
jersey-client:1.1.5.1

我受够了搜索google and stackoverflow，但是找不到任何解决方案.如果有人遇到相同的错误并解决了问题，请提出一些解决方案.

I am fed up searching google and stackoverflow, but could not find any solution. Please suggest some solution if any one faced the same error and solved the problem.

推荐答案

我找到了问题的解决方案.这是由于jar冲突引起的. 我将jersey-client:1.1.5.1更改为jersey-client:1.18

I got the solution of the problem. It was due to jar conflicts. I change jersey-client:1.1.5.1 to jersey-client:1.18
