在 Spring Boot 中使用切面来拦截操作日志,以及配合使用 MyBatis-Plus 框架进行操作,并使用 Thymeleaf 视图显示商品列表,同时配置 Logback 日志输出到文件。
sql
CREATE TABLE product (
id BIGINT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(255) NOT NULL,
price DECIMAL(10, 2) NOT NULL,
description TEXT
);
INSERT INTO product (name, price, description) VALUES
('商品 1', 100.00, '商品描述 1'),
('商品 2', 150.00, '商品描述 2'),
('商品 3', 200.00, '商品描述 3'),
('商品 4', 50.00, '商品描述 4'),
('商品 5', 300.00, '商品描述 5'),
('商品 6', 120.00, '商品描述 6'),
('商品 7', 80.00, '商品描述 7'),
('商品 8', 250.00, '商品描述 8'),
('商品 9', 180.00, '商品描述 9'),
('商品 10', 90.00, '商品描述 10');

WebLog类
java
/**
* Controller层的日志封装类
*/
@Data
@EqualsAndHashCode
public class WebLog {
/**
* 操作描述
*/
private String description;
/**
* 操作用户
*/
private String username;
/**

private Long startTime;

/**

private String ip;
/**

private Object parameter;
/**

}
创建切面类
拦截操作日志并将其转化为 JSON 格式,输出转换后的 JSON 数据。
java
@Aspect
@Component
public class LogAspect{
private static final Logger LOGGER = LoggerFactory.getLogger(LogAspect.class);
@Autowired
public final ObjectMapper objectMapper;
//切入点定义:拦截所有Controller方法
@Pointcut("execution(* com.icoderoad.example.product.controller.*.*(..))")
public void webLog(){
}
//在方法返回后执行
@AfterReturning(returning="result",pointcut="webLog()")
public void doAfterReturning(JoinPoint joinPoint,Object result) throws Throwable {
//获取当前请求的属性
ServletRequestAttributes attributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
//创建weblog对象,并填充信息
WebLog webLog = new WebLog();
webLog.setStartTime(System.currentTimeMillis());
webLog.setBasePath(request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort());
webLog.setUri(request.getRequestURI());
webLog.setUrl(request.getRequestURL().toString());
webLog.setMethod(request.getMethod());
webLog.setIp(getClientIp(request)); // 获取客户端真实 IP 地址
webLog.setParameter(Arrays.toString(joinPoint.getArgs()));
webLog.setResult(result);
//将WebLog对象转换为JSON格式,并输出到控制台(实际应该输出到日志文件)
String logJson = objectMapper.writeValueAsString(webLog);
LOGGER.info(logJson);
}
// 获取客户端真实 IP 地址
private String getClientIp(HttpServletRequest request) {
String ipAddress = request.getHeader("X-Forwarded-For");
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getHeader("Proxy-Client-IP");
}
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getHeader("WL-Proxy-Client-IP");
}
if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {
ipAddress = request.getRemoteAddr();
}
if (ipAddress != null && ipAddress.contains(",")) {
ipAddress = ipAddress.split(",")[0].trim();
}
return ipAddress;
}
}
项目启动类,启动的时候扫描mapper所在的包
java
@SpringBootApplication
@MapperScan("com.icoderoad.example.product.mapper")
public class AopLogbackProductApplication {
public static void main(String[] args) {
SpringApplication.run(AopLogbackProductApplication.class, args);
}
}
