Unmarshall json @POST parameter

Question

我有一个看起来像这样的类：

public class Test {
    @JsonProperty("name")
    private String name;
    public Test(){}
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

还有一个使用 javax.ws.rs 的端点类：

@Path("/Test")
public class Endpoint {
    @POST
    @Consumes("application/json")
    @Produces("application/json")
    @HeaderParam("Accept") @DefaultValue("application/json")
    public Response createTest(String json) {
        return Response.status(Response.Status.ACCEPTED).entity(json).build();
    }
}

这按预期工作。

问：如何使 createTest（） 将"Test"类作为参数而不是"字符串"？

试用：使用"Test"作为创建Test（）的参数时，发送以下内容会给出"415不支持的媒体类型"：

POST ../Endpoint/ HTTP/1.1
Host: localhost:8080
Accept: application/json
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 56d06798-2b32-57fc-c22a-0240aceb8f98
{
  "name": "Kalle"
}

我认为你必须使用泽西岛2.xx版本。

public class LoginRequest {
private String userName;
private String password;
public LoginRequest(){
    super();
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}
public String getPassword() {
    return password;
}
public void setPassword(String password) {
    this.password = password;
}
}

您的 Bean 资源（这是您的 Bean 测试）

@POST
@Path("login")
@Consumes(MediaType.APPLICATION_JSON)
public Response login(LoginRequest request) {
....
}

415 不支持的媒体类型问题的原因是您没有正确的依赖项。
