我有一个宁静的服务(post)消耗(application/json)并生成(application/json).此服务的单个参数是带注释的java对象.

我正在使用org.jboss.resteasy.client.ClientRequest将请求发送到服务.但是,我在客户端获得此异常并且异常:

找不到内容类型application/json类型的writer.

这是否意味着我缺少一些图书馆罐子,或者我必须为application/json编写自己的编写器？

我正在使用resteasy 2.3.3.Final

以下是我添加到我的pom中的各种依赖项,我认为可能与之相关:

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxrs</artifactId>
        <version>2.3.3.Final</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>2.0.5</version>
    </dependency>

    <dependency>
       <groupId>org.jboss.resteasy</groupId>
       <artifactId>resteasy-jaxb-provider</artifactId>
       <version>2.3.4.Final</version>
    </dependency>

       <artifactId>resteasy-jackson-provider</artifactId>

    </dependency>

    <dependency>
        <groupId>org.codehaus.jackson</groupId>

    </dependency>

对于REST服务(RESTeasy),我创建了JUnit测试用例,例如:

@Test
public void a100_insertAddressTest() throws Exception {
     Address addr = new Address(1, "testStreet", "1", (short) 1234,
     "testCity");

    ClientRequest request = new ClientRequest(BASE_URL + "customerID/{id}",
            sslExecutor_schusb);
    request.body(MediaType.APPLICATION_XML, addr).pathParameter(
            "id", 1);
    ClientResponse<String> response = request.post(String.class);

    Assert.assertEquals(201, response.getStatus());

    response.releaseConnection();
    request.clear();
}

如果我将请求主体的媒体类型更改为"application/json",则测试用例将失败并显示错误:
