1：pom.xml依赖

<!-- SpringBoot 拦截器 -->
<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2：注解类样例

package com.hgfr.gfs.logconfig.controller;

import java.lang.annotation.*;

/**
 * 自定义操作日志记录注解
 */
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface BusinessLog {
    /**
     * 操作人名称
     */
    public String OperationName() default "";

}

3：枚举类

package com.hgfr.gfs.logconfig.controller;

public enum BusinessType {
    ADD("新增"),
    UPDATE("修改"),
    OTHER("其他"),
    EXPORT_IN("导入"),
    EXPORT_OUT("导出"),
    DELETE("删除");

    private String value;

    BusinessType(String s) {
        this.value =s;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

4：具体处理方法类

package com.hgfr.gfs.logconfig.controller;

5：线程池类

package com.hgfr.gfs.logconfig.controller;


import lombok.extern.slf4j.Slf4j;

import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.RejectedExecutionHandler;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

@Slf4j
public class ThreadPoolFactory {

    /**
     * 线程池信息： 核心线程数量5，最大数量10，队列大小20，超出核心线程数量的线程存活时间：30秒， 指定拒绝策略的
     */
    public static final ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(5, 10, 30, TimeUnit.SECONDS,
            new LinkedBlockingQueue<Runnable>(20), new RejectedExecutionHandler() {
        @Override
        public void rejectedExecution(Runnable r, ThreadPoolExecutor executor) {
            log.error("有任务被拒绝执行了");
        }
    });

}
