我目前正在尝试使用 CXF 2.6.4 为 REST 应用程序开发一个简单的概念证明。我正在采用非弹簧方法。我使用 JBoss AS 7.1.1 Final 作为我的 Web 服务器。
以下是我的网络服务类:
package restful.webservice;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import restful.entity.ControllerVersion;
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class WebServiceRest implements WebServiceInterface
{
@Override
@POST
@GET
@Path("/getVersion")
public ControllerVersion getVersion(String deviceID, String[] macAddresses)
{
return new ControllerVersion();
}
}
控制器版本类:
package restful.entity;
@XmlRootElement(name = "ControllerVersion")
public class ControllerVersion {
private String version="R1.1.0.0";
public String getVersion() {
return version;
}
}
现在,当我尝试对我的 Web 服务进行 REST 调用时,我在服务器端收到以下异常:
18:51:52,913 WARNING [org.apache.cxf.jaxrs.utils.JAXRSUtils] (http--0.0.0.0-8080-1) No message body reader has been found for request class String[], ContentType : application/json.

我在 WEB-INF/lib 下拥有的库是:
cxf-api-2.6.4.jar
cxf-bundle-2.6.4.jar
cxf-rt-frontend-jaxrs-2.6.4.jar
cxf-rt-frontend-jaxrs.jar
cxf-rt-transports-http-2.6.4.jar
geronimo-servlet.jar
jaxb-api-2.2.5.jar
jaxb-impl-2.2.5.1.jar
jaxb-xjc-2.2.5.1.jar
jettison-1.3.4.jar
log4j-1.2.16.jar
neethi-3.0.2.jar
xmlschema-core-2.0.3.jar
有趣的是我尝试做另一个项目,但是这次在我的 Web 服务方法的签名中,我包含了一个自定义类。我在阅读自定义类实例的内容时没有问题,在将其返回给我的客户时也没有问题。
我错过了什么吗?
更新: 我尝试将以下内容添加到我的 web.xml:
<init-param>
<param-name>jaxrs.providers</param-name>
<param-value>
org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider
(writeXsiType=false)
</param-value>
</init-param>
并添加了以下依赖项:
jackson-jaxrs-1.9.2.jar
jackson-mapper-asl-1.9.2.jar
jackson-xc-1.9.2.jar
现在我收到以下异常:

更新 2: 我尝试实现一个具有不同签名的方法,而这一次,我从方法中省略了 String 数组:
public ControllerVersion getVersion(String deviceID)
没有字符串数组,一切都运行良好。你觉得我应该怎么做?
