实体
@Data
@Accessors(chain = true, fluent = true)
@Entity
@Table(name = "T_NOTE")
@Access(AccessType.FIELD)
public class Note implements Serializable
{
@Id
@GeneratedValue
private Long id;
private Date date;
@Column(length = 2000)
private String content;
private String title;
private String weather;
}
存储库
@RepositoryRestResource(collectionResourceRel = "note", path = "note")
public interface NoteRepository extends AbstractRepository<Note, Long>
{
}
获取http://localhost:8080/note/2
{
"_links": {
"self": {
"href": "http://localhost:8080/note/2"
}
}
}
没有实体字段数据,为什么?
EIDT
添加标准的setter / getter后,现在一切正常。
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
public Date getDate()
{
return date;
}
public void setDate(Date date)
{
this.date = date;
}
public String getContent()
{
return content;
}
public void setContent(String content)
{
this.content = content;
}
public String getTitle()
{
return title;
}
public void setTitle(String title)
{
this.title = title;
}
public String getWeather()
{
return weather;
}
public void setWeather(String weather)
{
this.weather = weather;
}
这是杰克逊映射器的原因吗?我如何使用流畅的API?为什么不使用反射来生成JSON?
修改
我需要的是这个配置
@Configuration
@Import(RepositoryRestMvcConfiguration.class)
public class ShoweaRestMvcConfiguration extends RepositoryRestMvcConfiguration
{
@Override
protected void configureJacksonObjectMapper(ObjectMapper mapper)
{
mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE);
mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
}
}
由this
引起答案 0 :(得分:1)
@Accessors
可能会踩过@Data
注释,而fluent = true
会生成与字段名称相同的getter,例如id()
和date()
(@Accessor documentation)。这就是为什么Spring没有看到任何领域的原因。
我认为您可以安全地删除@Accessors
和@Access
,因为@Access
采用id
的默认值(如果您注释了该字段,则会是FIELD
,如果您注释了getter,它将是PROPERTY
)。
