SpringBoot 记录操作日志

目录结构：

1、创建springboot项目，添加依赖。

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2、自定义注解@Log

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

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {

    String value() default "";

}

3、设置切面

import com.wzq.log.annotation.Log;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

@Aspect
@Component
public class LogAspect {
    @Pointcut("@annotation(com.wzq.log.annotation.Log)")
    public void logPointCut() {
    }

    @Around("logPointCut()")
    public Object around(ProceedingJoinPoint point) throws Throwable, InterruptedException {
        System.out.println("=============================");
        Object result = point.proceed();
        MethodSignature signature = (MethodSignature) point.getSignature();
        Method method = signature.getMethod();
        String name = method.getName();
        System.out.println("Method Name:" + name);//输出方法名
        Log log = method.getAnnotation(Log.class);
        System.out.println("Log Value:" + log.value());//输出注解里面的值
        System.out.println("+++++++++++++++++++++++++++++");
        return result;
    }
}

4、Controller用户测试效果

import com.wzq.log.annotation.Log;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

@RestController
public class TestController {

    @GetMapping("/list")
    @Log("获取Student列表")
    public List list() {
        List list = new ArrayList();
        for(int i = 0 ; i < 10 ; i++){
            Student student = new Student();
            student.setId(i);
            student.setName("name"+i);
            list.add(student);
        }
        return list;
    }

    @GetMapping("/getone")
    @Log("获取Student")
    public Student success() {
        Student student = new Student();
        student.setId(10);
        student.setName("name"+10);
        return student;
    }

}

class Student implements Serializable {
    private Integer id;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

浏览器返回数据：

http://localhost:8080/list

http://localhost:8080/getone

控制台打印:
