从MySQL数据库用户表构建API表，但是测试时，我将获得404状态。任何建议

Question

我试图测试API，但我获得了404状态。有什么建议吗？
测试后： { “时间戳”：“ 2022-03-29T01：50：58.126+00：00”， “状态”：404， “错误”：“找不到”， “路径”：“/api/v1/用户” } 我不确定问题本身是否出现在数据库本身中，还是控制器的代码出现问题？

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

    @Column(name = "username")
    private String userName;

    @Column(name = "password")
    private String password;

    @Column(name = "email" )
    private String email;

    @Column(name = "first_name")
