1、设计用户操作日志表: sys_oper_log
对应实体类为SysOperLog.java
import com.baomidou.mybatisplus.annotation.IdType; import com.baomidou.mybatisplus.annotation.TableId; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import lombok.EqualsAndHashCode; import lombok.experimental.Accessors; import java.io.Serializable; import java.util.Date; /** ** 操作日志记录 *
*/ @Data @EqualsAndHashCode(callSuper = false) @Accessors(chain = true) public class SysOperLog implements Serializable { private static final long serialVersionUID = 1L; @TableId(value = "id", type = IdType.AUTO) @ApiModelProperty("主键Id") private Integer id; @ApiModelProperty("模块标题") private String title; @ApiModelProperty("参数") private String optParam; @ApiModelProperty("业务类型（0其它 1新增 2修改 3删除）") private Integer businessType; @ApiModelProperty("路径名称") private String uri; @ApiModelProperty("操作状态（0正常 1异常）") private Integer status; @ApiModelProperty("错误消息") private String errorMsg; @ApiModelProperty("操作时间") private Date operTime; }
2、引入依赖
com.alibaba fastjson 2.0.9 org.springframework.boot spring-boot-starter-aop
3、自定义用户操作日志注解
MyLog.java
import java.lang.annotation.*;
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MyLog {
// 自定义模块名，eg:登录
String title() default "";
// 方法传入的参数
String optParam() default "";
// 操作类型，eg:INSERT, UPDATE...
BusinessType businessType() default BusinessType.OTHER;
}BusinessType.java — 操作类型枚举类
public enum BusinessType {
// 其它
OTHER,
// 查找
SELECT,
// 新增
INSERT,
// 修改
UPDATE,
// 删除
DELETE,
}4、自定义用户操作日志切面
LogAspect.java
import com.alibaba.fastjson.JSONObject;
import iot.sixiang.license.entity.SysOperLog;
import iot.sixiang.license.handler.IotLicenseException;
import iot.sixiang.license.jwt.UserUtils;
import iot.sixiang.license.service.SysOperLogService;
import lombok.extern.slf4j.Slf4j;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;

@Aspect

public class LogAspect {
/**

*/
@Autowired
private SysOperLogService sysOperLogService;
/**

*/
@Pointcut("@annotation(xxx.xxx.xxx.MyLog)")
public void logPointCut() {
log.info("------>配置织入点");
}
/**

*

*/
@AfterReturning(pointcut = "logPointCut()")
public void doAfterReturning(JoinPoint joinPoint) {
handleLog(joinPoint, null);
}
/**

* @param e 异常
*/
@AfterThrowing(value = "logPointCut()", throwing = "e")
public void doAfterThrowing(JoinPoint joinPoint, Exception e) {
handleLog(joinPoint, e);
}
private void handleLog(final JoinPoint joinPoint, final Exception e) {
// 获得MyLog注解
MyLog controllerLog = getAnnotationLog(joinPoint);
if (controllerLog == null) {
return;
}
SysOperLog operLog = new SysOperLog();
// 操作状态（0正常 1异常）
operLog.setStatus(0);
// 操作时间
operLog.setOperTime(new Date());
if (e != null) {
operLog.setStatus(1);
// IotLicenseException为本系统自定义的异常类，读者若要获取异常信息，请根据自身情况变通
operLog.setErrorMsg(StringUtils.substring(((IotLicenseException) e).getMsg(), 0, 2000));
}
// UserUtils.getUri();获取方法上的路径 如：/login，本文实现方法如下：
// 1、在拦截器中 String uri = request.getRequestURI();
// 2、用ThreadLocal存放uri，UserUtils.setUri(uri);
// 3、UserUtils.getUri();
String uri = UserUtils.getUri();
operLog.setUri(uri);
// 处理注解上的参数
getControllerMethodDescription(joinPoint, controllerLog, operLog);
// 保存数据库
sysOperLogService.addOperlog(operLog.getTitle(), operLog.getBusinessType(), operLog.getUri(), operLog.getStatus(), operLog.getOptParam(), operLog.getErrorMsg(), operLog.getOperTime());
}
/**
* 是否存在注解，如果存在就获取，不存在则返回null
* @param joinPoint
* @return
*/
private MyLog getAnnotationLog(JoinPoint joinPoint) {
Signature signature = joinPoint.getSignature();
MethodSignature methodSignature = (MethodSignature) signature;

if (method != null) {
return method.getAnnotation(MyLog.class);
}
return null;
}
/**

/**

*/
private String getAnnotationValue(JoinPoint joinPoint, String name) {
String paramName = name;
// 获取方法中所有的参数
Map params = getParams(joinPoint);
// 参数是否是动态的:#{paramName}
if (paramName.matches("^#\\{\\D*\\}")) {
// 获取参数名,去掉#{ }
paramName = paramName.replace("#{", "").replace("}", "");
// 是否是复杂的参数类型:对象.参数名
if (paramName.contains(".")) {
String[] split = paramName.split("\\.");
// 获取方法中对象的内容
Object object = getValue(params, split[0]);
// 转换为JsonObject
JSONObject jsonObject = (JSONObject) JSONObject.toJSON(object);
// 获取值
Object o = jsonObject.get(split[1]);
return String.valueOf(o);
} else {// 简单的动态参数直接返回
StringBuilder str = new StringBuilder();
String[] paraNames = paramName.split(",");
for (String paraName : paraNames) {
String val = String.valueOf(getValue(params, paraName));
// 组装成 userName=xxx,password=xxx,
str.append(paraName).append("=").append(val).append(",");
}
// 去掉末尾的,
if (str.toString().endsWith(",")) {
String substring = str.substring(0, str.length() - 1);
return substring;
} else {
return str.toString();
}
}
}
// 非动态参数直接返回
return name;
}
/**

* @param joinPoint
* @return
*/
public Map getParams(JoinPoint joinPoint) {
Map params = new HashMap<>(8);
// 通过切点获取方法所有参数值["zhangsan", "123456"]
Object[] args = joinPoint.getArgs();
// 通过切点获取方法所有参数名 eg:["userName", "password"]
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
String[] names = signature.getParameterNames();
for (int i = 0; i < args.length; i++) {
params.put(names[i], args[i]);

return params;
}

for (Map.Entry entry : map.entrySet()) {
if (entry.getKey().equals(paramName)) {
return entry.getValue();
}
}
return null;
}
} 5、MyLog注解的使用
@GetMapping("login")
@MyLog(title = "登录", optParam = "#{userName},#{password}", businessType = BusinessType.OTHER)
public DataResult login(@RequestParam("userName") String userName, @RequestParam("password") String password) {
...
}6、最终效果
