基于注解和Spring-AOP记录接口层操作日志
在项目开发中我们需要记录接口的操作日志：包含请求参数、响应参数、接口所属模块、接口功能描述、请求地址、ip地址等信息；实现思路很简单就是基于注解和aop的方式去记录日志，主要的难点在于日志表结构、注解的设计已经aop实现的一些比较好的实现方式的借鉴。
1.表和实体设计
1.实体设计
实体基类
@Data
//映射将仅应用于其子类
@MappedSuperclass
//指定要用于实体或映射超类的回调侦听器类。此注释可以应用于实体类或映射的超类。
@EntityListeners(AuditingEntityListener.class)
public class BaseEntity implements Serializable {
/**
* @Id 注解标识
* @GeneratedValue(generator = "snowflakeIdIDGenerator") 指定生成策略
* @GenericGenerator(name = "snowflakeIdIDGenerator", strategy = "net.cqnews.base.idconfig.SnowflakeIdGenerator")
* name 唯一的生成器名称
* strategy 生成器策略可以是预定义的 Hibernate 策略或完全限定的类名。
* parameters 可选的生成器参数。
*/
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(columnDefinition = "bigint(20) COMMENT '主键Id'")
private Long id;
@CreatedBy
@Column(columnDefinition = "bigint(20) COMMENT '创建人Id'")
private Long createId;
@CreatedDate
@Column(columnDefinition = "datetime COMMENT '创建时间'")
private Date createTime;
@LastModifiedBy
@Column(columnDefinition = "bigint(20) COMMENT '修改人Id'")
private Long updateId;
@LastModifiedDate
@Column(columnDefinition = "datetime COMMENT '修改时间'")
private Date updateTime;
/**
* 是否删除
*/
@Column(columnDefinition = "tinyint default 0 COMMENT '是否删除，默认否'")
private Boolean deleted = Boolean.FALSE;
}
操作日志表实体
@Entity
@Data
//指定表名
@Table(name = "sys_oper_log")
//表名注释
@org.hibernate.annotations.Table(appliesTo = "sys_oper_log", comment = "系统操作日志表")
public class SysOperLog extends BaseEntity {
@Column(columnDefinition = "varchar(50) COMMENT '模块标题'")
private String title;
@Column(columnDefinition = "varchar(255) COMMENT '接口功能描述'")
private String description;
@Column(columnDefinition = "varchar(100) COMMENT '方法名称'")
private String method;
@Column(columnDefinition = "varchar(10) COMMENT '请求方式'")
private String requestMethod;
@Column(columnDefinition = "varchar(50) COMMENT '操作人员名称'")
private String operatorName;
@Column(columnDefinition = "varchar(255) COMMENT '请求URL'")
private String requestUrl;
@Column(columnDefinition = "varchar(255) COMMENT '主机地址'")
private String requestIp;
@Column(columnDefinition = "varchar(255) COMMENT '操作地点'")
private String operationLocation;
@Column(columnDefinition = "varchar(2000) COMMENT '请求参数'")
private String operatorParam;
@Column(columnDefinition = "varchar(2000) COMMENT '返回参数'")
private String jsonResult;
@Enumerated(EnumType.STRING)
@Column(columnDefinition = "varchar(20) COMMENT '操作状态'")
private StatusEnum status;
@Column(columnDefinition = "varchar(2000) COMMENT '错误描述'")
private String errorMsg;
}
状态枚举类
@AllArgsConstructor
@Getter
public enum StatusEnum {
SUCCESS,
FAIL
}
2.表结构设计
CREATE TABLE `sys_oper_log` (
`id` bigint NOT NULL AUTO_INCREMENT COMMENT '主键Id',
`create_id` bigint DEFAULT NULL COMMENT '创建人Id',
`create_time` datetime DEFAULT NULL COMMENT '创建时间',
`deleted` tinyint DEFAULT '0' COMMENT '是否删除，默认否',
`update_id` bigint DEFAULT NULL COMMENT '修改人Id',
`update_time` datetime DEFAULT NULL COMMENT '修改时间',
`description` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '接口功能描述',
`error_msg` varchar(2000) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '错误描述',
`json_result` varchar(2000) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '返回参数',
`method` varchar(100) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '方法名称',
`operation_location` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '操作地点',
`operator_name` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '操作人员名称',
`operator_param` varchar(2000) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '请求参数',
`request_ip` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '主机地址',
`request_method` varchar(10) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '请求方式',
`request_url` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '请求URL',
`status` varchar(20) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '操作状态',
`title` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '模块标题',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT='系统操作日志表';
2.日志注解
参考下面这段swagger接口文档属性的方式，在controller层日志记录主要包含：接口所属模块、接口功能描述、请求参数、响应参数等
当然请求参数和响应参数不是每个接口都会包含的，因此这里注解设计了isSaveRequestData是否保存请求参数、isSaveResponseData是否保存响应的参数两个字段便于灵活控制，当然我们在做日志记录处理时也需要考虑为空的情况。
@Log(title = "测试模块",description = "更新配置")
@ApiOperation(value = "更新配置")
@RequestMapping(value = "/update", method = RequestMethod.PUT)
public BaseResult update(@Validated @RequestBody AuthConfigUpdateRequest request) {
return BaseResult.judgeOperate(authConfigService.update(request));
}
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
/**
* 接口所属模块
*/
public String title() default "";
/**
* 接口功能描述
*/
public String description() default "";
/**
* 是否保存请求的参数
*/
public boolean isSaveRequestData() default true;
/**
* 是否保存响应的参数
*/
public boolean isSaveResponseData() default true;
}
3.核心AOP类
我们设计的@Log注解主要用于修饰controller层，MyLogAspect主要就是对被@Log修饰的目标方法做增强处理，包含处理完请求后执行：记录目标方法正在执行的日志、处理请求异常后执行：记录目标方法执行错误的日志
@Slf4j
@Aspect

5.测试类
在需要记录日志的目标方法添加我们自定义的@Log注解，通过aop记录日志
@Api(tags = "测试模块")
@RestController
@RequiredArgsConstructor
@RequestMapping(value = "/test")
public class AuthController {
private final AuthConfigService authConfigService;
@Log(title = "测试模块",description = "更新配置")
@ApiOperation(value = "更新配置")
@RequestMapping(value = "/update", method = RequestMethod.PUT)
public BaseResult update(@Validated @RequestBody AuthConfigUpdateRequest request) {
return BaseResult.judgeOperate(authConfigService.update(request));
}
@Log(title = "测试模块",description = "新增配置")
@ApiOperation(value = "新增配置")
@RequestMapping(value = "/create", method = RequestMethod.POST)
public BaseResult create(@Validated @RequestBody AuthConfigRequest request) {
return BaseResult.judgeOperate(authConfigService.create(request));
}
@Log(title = "测试模块",description = "删除配置")
@ApiOperation(value = "删除配置")
@DeleteMapping(value = "/delete/{ids}")
@ApiImplicitParams({
@ApiImplicitParam(name = "ids", value = "配置id,多个id用逗号分隔", required = true)
})
public BaseResult delete(@PathVariable("ids") List<Long> ids) {
return BaseResult.judgeOperate(authConfigService.delete(ids));
}
@Log(title = "测试模块",description = "配置分页")
@ApiOperation(value = "配置分页")
@RequestMapping(value = "/list", method = RequestMethod.GET)
public BaseResult<PageResponse<AuthConfigListResponse>> list(@RequestBody AuthConfigListRequest request) {
return BaseResult.success(PageResponse.getInstance(authConfigService.list(request)));
}
@Log(title = "测试模块",description = "根据appId获取配置信息")
@ApiOperation(value = "根据appId获取配置信息")
@RequestMapping(value = "/detail", method = RequestMethod.GET)
public BaseResult<EduAuthConfig> detail(String appId) {
return BaseResult.success(authConfigService.getAuthConfig(appId));
}
}
