如何绕过HTTP错误415-不支持的媒体类型

Question

我正在使用Restet，我想知道如果设置了ServerResource实体类型，例如，对于这种类型的实体，是否可能：

@XStreamAlias("role")
@ApiModel
public class Role {

    private String entityId;
    private String name;

    @ApiModelProperty(required = false, value = "")
    private List<String> aclRead;
    @ApiModelProperty(required = false, value = "")
    private List<String> acLWrite;
    @ApiModelProperty(required = false, value = "")
    private Boolean publicRead;
    @ApiModelProperty(required = false, value = "")
    private Boolean publicWrite;

    public String getEntityId() {
        return entityId;
    }

    public void setEntityId(String entityId) {
        this.entityId = entityId;
    }

    public String getName() {
        return name;
    }

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

    public List<String> getAclRead() {
        return aclRead;
    }

    public void setAclRead(List<String> aclRead) {
        this.aclRead = aclRead;
    }

    public List<String> getAcLWrite() {
        return acLWrite;
    }

    public void setAcLWrite(List<String> acLWrite) {
        this.acLWrite = acLWrite;
    }

    public Boolean getPublicRead() {
        return publicRead;
    }

    public void setPublicRead(Boolean publicRead) {
        this.publicRead = publicRead;
    }

    public Boolean getPublicWrite() {
        return publicWrite;
    }

    public void setPublicWrite(Boolean publicWrite) {
        this.publicWrite = publicWrite;
    }

}

我们如何能够在不需要传递所有字段的情况下发布呢？在本例中，我们只想从客户端请求传递“name”，但这样做会引发415-不受支持的媒体类型

{
  "role" : {
     "name" : "AdminRole" 
  }
}

在post请求中，json数据应该只包含实体参数，而不包含实体名称作为根键。因此，您的post请求应该如下所示：

{
    "name" : "AdminRole" 
}
