Spring Boot AOP记录用户操作日志

在Spring框架中,使用AOP配合自定义注解可以方便的实现用户操作的监控。首先搭建一个基本的Spring Boot Web环境开启Spring Boot,然后引入必要依赖:


		
		
            org.springframework.boot
            spring-boot-starter-aop
        


		
		
			com.oracle
			ojdbc6
			11.2.0.4
		

		
		
		   com.alibaba
		   druid-spring-boot-starter
		   1.1.6
		

application.yml

server:
  context-path: /web
  port: 7002

spring:
  datasource:
    druid:
      # 数据库访问配置, 使用druid数据源 
      type: com.alibaba.druid.pool.DruidDataSource
      driver-class-name: oracle.jdbc.driver.OracleDriver
      url: jdbc:oracle:thin:@localhost:49161:XE
      username: boot
      password: 123456   
      # 连接池配置
      initial-size: 5
      min-idle: 5
      max-active: 20
      # 连接等待超时时间
      max-wait: 30000
      # 配置检测可以关闭的空闲连接间隔时间
      time-between-eviction-runs-millis: 60000
      # 配置连接在池中的最小生存时间
      min-evictable-idle-time-millis: 300000
      validation-query: select '1' from dual
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      # 打开PSCache,并且指定每个连接上PSCache的大小
      pool-prepared-statements: true
      max-open-prepared-statements: 20
      max-pool-prepared-statement-per-connection-size: 20
      # 配置监控统计拦截的filters, 去掉后监控界面sql无法统计, 'wall'用于防火墙
      filters: stat,wall
      # Spring监控AOP切入点,如x.y.z.service.*,配置多个英文逗号分隔
      aop-patterns: com.springboot.servie.*
      
    
      # WebStatFilter配置
      web-stat-filter:
        enabled: true
        # 添加过滤规则
        url-pattern: /*
        # 忽略过滤的格式
        exclusions: '*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*'
      
      # StatViewServlet配置 
      stat-view-servlet:
        enabled: true
        # 访问路径为/druid时,跳转到StatViewServlet
        url-pattern: /druid/*
        # 是否能够重置数据
        reset-enable: false
        # 需要账号密码才能访问控制台
        login-username: druid
        login-password: druid123
        # IP白名单
        # allow: 127.0.0.1
        # IP黑名单(共同存在时,deny优先于allow)
        # deny: 192.168.1.218
      
      # 配置StatFilter
      filter: 
        stat: 
          log-slow-sql: true 


     

自定义注解

定义一个方法级别的@Log注解,用于标注需要监控的方法:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
    String value() default "";
}

创建库表和实体

在数据库中创建一张sys_log表,用于保存用户的操作日志,数据库采用oracle 11g:

CREATE TABLE "SCOTT"."SYS_LOG" (
   "ID" NUMBER(20) NOT NULL ,
   "USERNAME" VARCHAR2(50 BYTE) NULL ,
   "OPERATION" VARCHAR2(50 BYTE) NULL ,
   "TIME" NUMBER(11) NULL ,
   "METHOD" VARCHAR2(200 BYTE) NULL ,
   "PARAMS" VARCHAR2(500 BYTE) NULL ,
   "IP" VARCHAR2(64 BYTE) NULL ,
   "CREATE_TIME" DATE NULL 
);

COMMENT ON COLUMN "SCOTT"."SYS_LOG"."USERNAME" IS '用户名';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."OPERATION" IS '用户操作';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."TIME" IS '响应时间';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."METHOD" IS '请求方法';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."PARAMS" IS '请求参数';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."IP" IS 'IP地址';
COMMENT ON COLUMN "SCOTT"."SYS_LOG"."CREATE_TIME" IS '创建时间';

CREATE SEQUENCE seq_sys_log START WITH 1 INCREMENT BY 1;

库表对应的实体:

public class SysLog implements Serializable{

    private static final long serialVersionUID = -6309732882044872298L;
    
    private Integer id;
    private String username;
    private String operation;
    private Integer time;
    private String method;
    private String params;
    private String ip;
    private Date createTime;
    // get,set略
}

保存日志的方法

为了方便,这里直接使用Spring JdbcTemplate来操作数据库。定义一个SysLogDao接口,包含一个保存操作日志的抽象方法:

public interface SysLogDao {
    void saveSysLog(SysLog syslog);
}
@Repository
public class SysLogDaoImp implements SysLogDao {

    @Autowired
    private JdbcTemplate jdbcTemplate;
    
    @Override
    public void saveSysLog(SysLog syslog) {
        StringBuffer sql = new StringBuffer("insert into sys_log ");
        sql.append("(id,username,operation,time,method,params,ip,create_time) ");
        sql.append("values(seq_sys_log.nextval,:username,:operation,:time,:method,");
        sql.append(":params,:ip,:createTime)");
        
        NamedParameterJdbcTemplate npjt = new NamedParameterJdbcTemplate(this.jdbcTemplate.getDataSource());
        npjt.update(sql.toString(), new BeanPropertySqlParameterSource(syslog));
    }
}

切面和切点

定义一个LogAspect类,使用@Aspect标注让其成为一个切面,切点为使用@Log注解标注的方法,使用@Around环绕通知:

@Aspect
@Component
public class LogAspect {

    @Autowired
    private SysLogDao sysLogDao;
    
    @Pointcut("@annotation(com.springboot.annotation.Log)")
    public void pointcut() { }

    @Around("pointcut()")
    public Object around(ProceedingJoinPoint point) {
        Object result = null;
        long beginTime = System.currentTimeMillis();
        try {
            // 执行方法
            result = point.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;
        // 保存日志
        saveLog(point, time);
        return result;
    }

	private void saveLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        SysLog sysLog = new SysLog();
        Log logAnnotation = method.getAnnotation(Log.class);
        if (logAnnotation != null) {
            // 注解上的描述
            sysLog.setOperation(logAnnotation.value());
        }
        // 请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        sysLog.setMethod(className + "." + methodName + "()");
        // 请求的方法参数值
        Object[] args = joinPoint.getArgs();
        // 请求的方法参数名称
        LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
        String[] paramNames = u.getParameterNames(method);
        if (args != null && paramNames != null) {
            String params = "";
            for (int i = 0; i < args.length; i++) {
                params += "  " + paramNames[i] + ": " + args[i];
            }
            sysLog.setParams(params);
        }
        // 获取request
        HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
        // 设置IP地址
        sysLog.setIp(IPUtils.getIpAddr(request));
        // 模拟一个用户名
        sysLog.setUsername("mrbird");
        sysLog.setTime((int) time);
        sysLog.setCreateTime(new Date());
        // 保存系统日志
        sysLogDao.saveSysLog(sysLog);
    }
}

测试

TestController:

@RestController
public class TestController {

    @Log("执行方法一")
    @GetMapping("/one")
    public void methodOne(String name) { }
    
    @Log("执行方法二")
    @GetMapping("/two")
    public void methodTwo() throws InterruptedException {
        Thread.sleep(2000);
    }
    
    @Log("执行方法三")
    @GetMapping("/three")
    public void methodThree(String name, String age) { }
}
