问题描述

我遵循了官方文档，并尝试了许多已经提出的SO问题，但是没有任何效果。 有人可以帮我找到问题吗？

在这里，我添加了所有可以找到的细节。

web.xml ： 

<servlet>
    <servlet-name>REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <!-- Register resources and providers under com.stxt.rest package. -->
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.stxt.supercentral.rest</param-value>
    </init-param>
    <init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

资源api类 ： 

@Path("/agent")
@Component
public class AgentRestAPI {

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@Path("/")
public Response getAgent(@QueryParam("id") String agentId, Profile profile) {
    return ApiResponseFactory.generateResponse(agentId);
}

@GET
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@Path("/get")
public Response getAgent(@QueryParam("id") String agentId) {
    return ApiResponseFactory.generateResponse(agentId);
}

}

资源类别 ： 

public class Profile {

    private String profileId;
    private String emailAddress;
    private String name;

    public String getProfileId() {
        return profileId;
    }

    public void setProfileId(String profileId) {
        this.profileId = profileId;
    }

    public String getEmailAddress() {
        return emailAddress;
    }

    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Profile{" +
                "profileId='" + profileId + '\'' +
                ", emailAddress='" + emailAddress + '\'' +
                ", name='" + name + '\'' +
                '}';
    }
}

问题已解决。 在Jersey 2.*我们需要手动注册MessageBodyReader和MessageBodyWriters 。 这样的问题很好地解释了这一点。
