（B站云e办）SpringBoot开发项目实战记录（十）(个人中心功能)

一、修改用户信息接口

1.1 pojo层(自定义发序列化器)1.2 CustomAuthorityDeserializer 自定义的反序列化类

⭐知识点：@JsonDeserialize(using = CustomAuthorityDeserializer.class)这里使用自己写的反序列化进行反序列化

@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@TableName("t_admin")
@ApiModel(value="Admin对象", description="")
public class Admin implements Serializable, UserDetails {

    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "id")
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    @ApiModelProperty(value = "姓名")
    private String name;

    @ApiModelProperty(value = "手机号码")
    private String phone;

    @ApiModelProperty(value = "住宅电话")
    private String telephone;

    @ApiModelProperty(value = "联系地址")
    private String address;

    @ApiModelProperty(value = "是否启用")
    @Getter(AccessLevel.NONE)
    private Boolean enabled;

    @ApiModelProperty(value = "用户名")
    private String username;

    @ApiModelProperty(value = "密码")
    private String password;

    @ApiModelProperty(value = "用户头像")
    private String userFace;

    @ApiModelProperty(value = "备注")
    private String remark;


    @ApiModelProperty(value = "角色")
    @TableField(exist = false)
    private List roles;

    @Override
    @JsonDeserialize(using = CustomAuthorityDeserializer.class)
    public Collection getAuthorities() {
        List authorities = roles.stream().map(role -> new SimpleGrantedAuthority(role.getName())).collect(Collectors.toList());
        return authorities;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return enabled;
    }
}

public class CustomAuthorityDeserializer extends JsonDeserializer {

    @Override

        ObjectMapper mapper = (ObjectMapper) jsonParser.getCodec();
        JsonNode jsonNode = mapper.readTree(jsonParser);

        List grantedAuthorities = new linkedList<>();
        Iterator elements = jsonNode.elements();

        while (elements.hasNext()) {
            JsonNode next = elements.next();
            JsonNode authority = next.get("authority");
            grantedAuthorities.add(new SimpleGrantedAuthority(authority.asText()));
        }
        return grantedAuthorities;
    }
