在工作中我们可能会遇到一个需求，就是记录用户的操作信息，接下来使用spring的aop特性实现这一需求
一、首先引入我们必要的一些依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- aop依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<!-- oracle驱动 -->
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>6.0</version>
</dependency>
<!-- druid数据源驱动 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.6</version>
</dependency>二、自定义一个注解，用于标注需要监控的方法
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
String value() default "";
}三、在数据库中创建一张表，用来保存用户的操作日志
字段可以有 用户名 用户操作 请求方法 请求参数 响应时间 IP地址和创建时间
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;
四、创建数据库表中对应的实体类
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;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getOperation() {
return operation;
}
public void setOperation(String operation) {
this.operation = operation;
}
public Integer getTime() {
return time;
}
public void setTime(Integer time) {
this.time = time;
}
public String getMethod() {
return method;
}
public void setMethod(String method) {
this.method = method;
}
public String getParams() {
return params;
}
public void setParams(String params) {
this.params = params;
}
public String getIp() {
return ip;
}
public void setIp(String ip) {
this.ip = ip;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
}五、新增保存日志的方法
public interface SysLogDao {
void saveSysLog(SysLog syslog);
}然后是其实现方法
@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));
}
}六、定义切面和切点，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环绕通知文章来源：https://www.toymoban.com/news/detail-456988.html
@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);
}
}七、测试文章来源地址https://www.toymoban.com/news/detail-456988.html
@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) { }
