Question

我的班级看起来像这样：

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();
    }
}

这可以按预期工作。

问题：如何让createTest（）将“Test”类作为参数而不是“String”？

试用：当使用“Test”作为createTest（）的参数时，发送以下内容会显示“415 Unsupported Media Type”：

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Jersey 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;
}

}

你的Bean资源（这是你的Bean测试）

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

和家属：

<properties>
    <jersey.version>2.22.1</jersey.version>
    <jackson.version>2.6.1</jackson.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<version>1</version>

415不支持的媒体类型问题的原因是您没有正确的依赖性。
