spring加强：spring aop expression支持多个表达式配置

spring aop expression支持多个表达式配置

准备：

目标类UcUserFilesService 及目标方法insert()方法、update()方法及delete()方法（红色标注的是目标方法）

方案一：JavaConfig方式配置

切面、切点及前置通知UserFileChangeRecordAspect

package com.huajin.userserver.aop;

import java.util.Objects;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.huajin.exchange.enums.user.UserFileTypeDesc;
import com.huajin.exchange.userservice.domain.response.UcUserFiles;
import com.huajin.userserver.enums.UserFileOperateEnum;
import com.huajin.userserver.service.RedisService;
import com.huajin.userserver.service.UcUserFilesService;
import com.huajin.userserver.utils.CacheKey;

import lombok.extern.slf4j.Slf4j;

/**
 * 用户文件操作记录切面
 *
 * @author hongwei.lian
 * @date 2018年11月12日 下午7:23:08
 */
@Aspect
@Component("userFileChangeRecordAspect")
@Slf4j
public class UserFileChangeRecordAspect {
	
	@Autowired
	private UcUserFilesService ucUserFilesService;
	
	@Autowired
	private RedisService redisService;
	
	/**
	 * 用户文件操作切点
	 * 
	 * @author hongwei.lian
	 * @date 2018年11月13日 下午1:59:26
	 */
	@Pointcut("execution(* com.huajin.userserver.service.UcUserFilesService.insert(..)) || " +
	        "execution(* com.huajin.userserver.service.UcUserFilesService.update(..)) || " +
	        "execution(* com.huajin.userserver.service.UcUserFilesService.delete(..))")
	public void pointCut() {}
	
	/**

	 *
	 * @param point
	 * @param returnValue 
	 * @author hongwei.lian
	 * @date 2018年11月12日 下午7:24:30
	 */
	@Before("pointCut()")
	public void userFileOperatorRecord(JoinPoint joinPoint) {
		try {
			//-- 1、获取目标方法名称和目标方法参数信息，获取旧文件记录
			UcUserFiles olducUserFiles = null;
			Integer userId = null;
			Integer fileType = null;
			String methodName = joinPoint.getSignature().getName();
			if (Objects.equals(methodName, UserFileOperateEnum.DELETE.getDesc())) {
				Integer id = (Integer) joinPoint.getArgs()[1];
				olducUserFiles = ucUserFilesService.getById(null, id);
				if (Objects.nonNull(olducUserFiles)) {
					userId = olducUserFiles.getUserId();
					fileType = olducUserFiles.getFileType();
				}
			} else {
				UcUserFiles ucUserFiles = (UcUserFiles) joinPoint.getArgs()[1];
				if (Objects.nonNull(ucUserFiles)) {
					userId = ucUserFiles.getUserId();
					fileType = ucUserFiles.getFileType();
				}
				olducUserFiles = ucUserFilesService.getUserFileByUserIdAndFileType(userId, fileType);
			}
			//-- 组装用户文件缓存key
			String userInfoKey = "";
			if (Objects.equals(fileType, UserFileTypeDesc.入会申请书.value)) {
				userInfoKey = CacheKey.REDISCACHEKEY_USERFILE_APPLYMEMBERSHIP + userId;
			} else if (Objects.equals(fileType, UserFileTypeDesc.经办人身份证.value)) {
				userInfoKey = CacheKey.REDISCACHEKEY_USERFILE_OPERATORCARD + userId;
			} else if (Objects.equals(fileType, UserFileTypeDesc.机构营业执照.value)) {
				userInfoKey = CacheKey.REDISCACHEKEY_USERFILE_BUSINESSLICENSE + userId;
			} else if (Objects.equals(fileType, UserFileTypeDesc.法定代表人身份证.value)) {
				userInfoKey = CacheKey.REDISCACHEKEY_USERFILE_REPRESENTATIVECARD + userId;
			}
			//-- 3、判断缓存中是否存在这个key，不存在则新增
			boolean nonStringKey = redisService.nonStringKey(userInfoKey);
			if (nonStringKey) {
				redisService.setStringKey(userInfoKey, Objects.isNull(olducUserFiles) ? "" : olducUserFiles.allFileNames());
			}
		} catch (Exception e) {
			log.error("", e);
		}
	}
	
}

从上面的JavaConfig配置可以看出spring aop expression是支持多个表达式配置的，中间可以使用逻辑运算符，支持的有and、or、也可以使用||、&&、!。需要注意一点使用and或者or注意大小写，尽量都写作小写，原因还需要深究。

 

方案二：XML方式配置

spring-aop.xml配置文件

相应的userFileChangeRecordAspect的userFileOperatorRecord方法逻辑和上面JavaConfig方式的方法逻辑是一样的，不再赘述
