springAop整合自定义注解做方法日志配置（源码在附件）

package com.aop.log.anno;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)//运行期
@Target({ElementType.METHOD,ElementType.TYPE})//作用于方法上,类上
public @interface Mylog {

   public String value() default "";//日志信息值

   boolean ingore() default false;//是否忽略

}

切面日志环绕通知

    }

    public String getName() {

    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name=‘" + name + ‘\‘‘ +
                ‘}‘;
    }
}

    //@Mylog(value = "user dao log",ingore = true)
    public void save(User user) throws InterruptedException;

    public void delete();
    public void update();
    public void find();

}
