Resteasy客户端抛出异常
Resteasy客户端抛出异常
提问于 2014-10-22 15:04:53
我试图编写一个简单的Resteasy客户端来访问mt服务。不幸的是，我得到了错误：
Exception in thread "main" org.jboss.resteasy.client.ClientResponseFailure: Unable to find a MessageBodyReader of content-type application/json and type null
at org.jboss.resteasy.client.core.BaseClientResponse.createResponseFailure(BaseClientResponse.java:523)
at org.jboss.resteasy.client.core.BaseClientResponse.createResponseFailure(BaseClientResponse.java:514)
at org.jboss.resteasy.client.core.BaseClientResponse.readFrom(BaseClientResponse.java:415)
at org.jboss.resteasy.client.core.BaseClientResponse.getEntity(BaseClientResponse.java:377)
at org.jboss.resteasy.client.core.BaseClientResponse.getEntity(BaseClientResponse.java:350)
at org.jboss.resteasy.client.core.BaseClientResponse.getEntity(BaseClientResponse.java:344)
at com.test.client.rest.employee.EmployeeClient.main(EmployeeClient.java:29)客户代码：
ClientRequest request = new ClientRequest(ROOT_URL + "getEmp/GS");
ClientResponse<Employee> resp = request.get(Employee.class);
//Response resp = request.get();
if(resp.getResponseStatus().getStatusCode() == 200)
{
System.out.println("resp ok!!!");
}
Employee e = resp.getEntity(Employee.class);
System.out.println("path:" + e);Rest服务代码：
@GET
@Path("getEmp/{name}")
@Produces("application/json")
public Employee getEmployee(@PathParam("name") String name)
{
if(em.containsKey(name))
return em.get(name);
else
throw new EmployeeNotFoundException("Employee with name '" + name + "' does not exists!");
}客户端代码响应正常。即200。相同的url在Mozilla客户端也可以正常工作。如能提供任何帮助，将不胜感激。

在添加jettison提供程序jars之后，问题得到了解决。
尽管如此，我仍然觉得Resteasy-2.3.2有一些问题，最终我把我的Reateasy升级到了2.3.5，并且客户端运行得很好。

确保您在客户端项目中拥有所有jackson库。如果您使用的是maven，您应该拥有以下内容：
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson-provider</artifactId>
<version>xxx</version>
</dependency>编辑: resteasy-jaxrs和resteasy-jackson-provider使用的jars如下
