java - HTTP/1.1 415 处理 JSON 时不支持的媒体类型

Question

我的代码可以使用 Xml，但使用 Json 时失败

使用 RestEasy UI 请求:

POST /api/people HTTP/1.1
Content-Type:application/json

{
    "name":"developer",
    "age":"25",
    "address":"address"
}

类Resource.java

package people;

@Path("/api")
public class Resource {

    @GET
    @Produces("text/plain")
    @Path("helloworld")
    public String helloWorld() {
        return "Hello World!";
    }

    @POST
    @Produces("text/plain")
    @Consumes(MediaType.APPLICATION_JSON)
    @Path("people")
    public String updatePeople(People request)  { 
        People p = new People();
        p.setName(request.getName());

        return p.getName(); 
    }
}

和 People.java 类

package people;

@XmlRootElement
public class People {

    private String name;
    private String age;
    private String address;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }

}

Answer 1

在 Bean 类 People 中添加默认构造函数。

 public people(){
   }
