java - 使用消息 "message": "Content type ' text/plain;charset=UTF- 8' not supported" 测试 Post API 时获取 415 状态代码

Question

使用Postman测试REST Controller (使用SpringBoot开发)时，反复获取415状态码。

仅在特定帖子请求时发生。其他帖子请求工作正常。模仿了工作岗位 Controller ，但没有成功。

@RequestMapping(value="/addtheatre", method= RequestMethod.POST)
public HttpStatus addTheatre(@RequestBody Theatre theatre ) {
theatrerepository.save(theatre);
return HttpStatus.OK;

}

剧院实体如下:-包 com.example.Model;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;
import org.springframework.stereotype.Component;

import javax.persistence.*;
import javax.validation.constraints.NotNull;
import java.sql.Time;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;


@Entity(name="Theatre")
public class Theatre {

    Theatre()
    {}
    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    @Column(name="Id")
    private long id;
    @Column(name="name")
    @NotNull
    private String name;
    @Column(name="address")
    @NotNull
    private String address;
    @Column(name="city")
    @NotNull
    private String city;
    @Column(name="is_active")
    @NotNull
    private Boolean is_active;
    @Transient
    private List<TheatreHall> halls;
    @Transient
    private Map <Movie,LinkedList<Time>> map;

    public Boolean getIs_active() {
        return is_active;
    }

    public void setIs_active(Boolean is_active) {
        this.is_active = is_active;
    }

    public List<TheatreHall> getHalls() {
        return halls;
    }

    public String getName() {
        return name;
    }

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

    public void setHalls(List<TheatreHall> halls) {
        this.halls = halls;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public Map<Movie, LinkedList<Time>> getMap() {
        return map;
    }

    public void setMap(Map<Movie, LinkedList<Time>> map) {
        this.map = map;
    }

    @Override
    public String toString() {
        return "Theatre{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", address='" + address + '\'' +
                ", city='" + city + '\'' +
                ", is_active=" + is_active +
                ", halls=" + halls +
                ", map=" + map +
                '}';
    }

}

Postman测试数据如下:-

端点:-localhost:8080/addtheatre

请求:-

{   
"name":"PVR Mall",
"address":"Andheri",
"city":"Mumbai",
"is_active":"true"
}

回应:-

{
    "timestamp": "2018-12-26T08:21:43.269+0000",
    "status": 415,
    "error": "Unsupported Media Type",
    "message": "Content type 'application/json;charset=UTF-8' not supported",
    "path": "/addtheatre"
}

预计此 POST Controller 状态正常。

Answer 1

将 is_active 更改为 isActive，将 setter 更改为 setIsActive。我怀疑 Jackson 由于命名约定而无法找到 is_active 的相关 setter，因此无法解析该对象
