AOP使用案例

一 自定义注解

import java.lang.annotation.*;

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented

public @interface Logger {
    //详情
    String detail() default  "";
}

二 业务逻辑

import com.example.gatewayacquisitionsystem.dto.SystemLogDTO;
import com.example.gatewayacquisitionsystem.service.SystemLogService;
import io.swagger.annotations.ApiOperation;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;
import pro.tjkj.zauth.client.util.ZAuthContextUtil;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;


@Aspect
@Component
public class LoggerAspect {
    @Resource
    private SystemLogService systemLogService;

    @Pointcut("@annotation(Logger)")
    public void loggerAspect() {
    }

    @After("loggerAspect()")
    public void afterFilter(JoinPoint joinPoint) {
        MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
        Logger logger = methodSignature.getMethod().getAnnotation(Logger.class);
        ApiOperation apiOperation = methodSignature.getMethod().getAnnotation(ApiOperation.class);
        HttpServletRequest httpServletRequest = ZAuthContextUtil.getRequest();
        SystemLogDTO systemLogDTO = new SystemLogDTO();
        systemLogDTO.setCreateDate(System.currentTimeMillis());//创建事件
        systemLogDTO.setMsg(apiOperation.value());//操作内容
        systemLogDTO.setRequestUrl(httpServletRequest.getRequestURL().toString());//请求url
        systemLogDTO.setRequestMode(httpServletRequest.getMethod());//请求方式
        systemLogService.insert(systemLogDTO);
        System.out.println("=========================start================================");
        System.out.println(httpServletRequest.getRequestURL());
        System.out.println(apiOperation.value());
        System.out.println(ZAuthContextUtil.getToken());
        System.out.println(httpServletRequest.getMethod());
        System.out.println(methodSignature.getMethod().getName());
        System.out.println(logger.detail());

    }
}

三 实现类产生日志保存用下面方法
