本文展示了三种不同类型的API响应数据结构：对象类型、字符串类型和分页类型。对象类型包含状态码、消息、数据和集合等字段，用于封装业务逻辑；字符串类型主要返回状态码和消息；分页类型则包含了分页信息和数据内容，用于查询接口。代码示例涵盖了从方法层到业务实现层再到控制层的使用情况。

1：接口返回值响应数据类型为对象

a: 代码段：

@ApiModel("接口返回值(响应数据类型为对象)")
public class Result<T> {

    @ApiModelProperty("响应状态码  200-成功，其余均不成功")
    private Integer code;
    @ApiModelProperty("响应信息")
    private String msg;

    @ApiModelProperty(hidden = true)
    @JsonInclude(Include.NON_NULL)
    private Integer number;
    @ApiModelProperty(hidden = true)
    @JsonInclude(Include.NON_NULL)
    private String content;

    @ApiModelProperty("响应数据 类")
    private T data;
    @ApiModelProperty("响应集合 类")
    private List<T> list;
    private List<T> content1 = new ArrayList<T>();
