knife4j是为Java MVC框架集成Swagger生成Api文档的增强解决方案。
前后端分离开发模式中,api文档是最好的沟通方式。
Swagger 是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。
1、及时性 (接口变更后,能够及时准确地通知相关前后端开发人员)
2、规范性 (并且保证接口的规范性,如接口的地址,请求方式,参数及响应格式和错误信息)
3、一致性 (接口信息一致,不会出现因开发人员拿到的文档版本不一致,而出现分歧)
4、可测性 (直接在接口文档上进行测试,以方便理解业务)

需要根据自己情况修改的地方
实体类添加注解:
@ApiModel(description = “”)
@ApiModelProperty(value = “”)
@Data
@ApiModel(description = "角色")
@TableName("sys_role")
public class SysRole extends BaseEntity {
private static final long serialVersionUID = 1L;
//@NotBlank(message = "角色名称不能为空")
@ApiModelProperty(value = "角色名称")
@TableField("role_name")
private String roleName;
@ApiModelProperty(value = "角色编码")
@TableField("role_code")
private String roleCode;
@ApiModelProperty(value = "描述")
@TableField("description")
private String description;
}
controller层添加注解:
@Api(tags = “角色管理”)//tag标签
@ApiOperation(value = “获去全部角色列表”)
@Api(tags = "角色管理")
@RestController
@RequestMapping("/admin/system/sysRole")
public class RoleController {
@Autowired
private RoleService roleService;
@ApiOperation(value = "获取全部角色列表")
@GetMapping("/findAll")
public Result findAll() {
List<SysRole> roleList = roleService.list();
return Result.ok(roleList);
}
}
访问地址:
http://localhost:8080/doc.html
@ApiOperation(value = "查询角色列表")
@GetMapping("/{page}/{limit}")
public Result selectRolePage(
@ApiParam(name = "page" ,value = "当前页数",required = true)
@PathVariable Integer page,
@ApiParam(name = "limit",value ="每页条数",required = true )
@PathVariable Integer limit,
//表单提交
SysRoleQueryVo sysRoleQueryVo){
IPage<SysRole> roleIPage
=new Page<>(page,limit);
//构建查询条件
QueryWrapper<SysRole> sysRoleQueryWrapper = new QueryWrapper<>();
String roleName = sysRoleQueryVo.getRoleName();
//传入的name不为空,则模糊查询
sysRoleQueryWrapper.like(roleName==null?false:true,"role_name",roleName);
//得到分页信息
IPage<SysRole> pageModel = roleService.page(roleIPage,sysRoleQueryWrapper);
return Result.ok(pageModel);
}
