Spring Boot日志处理

2.4 日志处理

2.4.1 记录日志内容

请求url
访问者ip
调用方法classMethod
参数args
返回内容

2.4.2 新建包aspect，新建日志切面处理类

@Aspect // 进行切面操作

	private class RequestLog {

		private String ip;// 访问者ip

		private String classMethod;// 调用方法

		private Object[] args;// 参数

		public RequestLog(String url, String ip, String classMethod, Object[] args) {

			super();

			this.url = url;

			this.ip = ip;

			this.classMethod = classMethod;

			this.args = args;

		}

		@Override

		public String toString() {

			return "[url=" + url + ", ip=" + ip + ", classMethod=" + classMethod + ", args=" + Arrays.toString(args)

					+ "]";

		}

	}// RequestLog

}// LogAspect

测试日志切面处理Controller

@Controller

public class IndexController {

	@GetMapping("/{id}/{name}")

	public String toIndex(@PathVariable("id") Integer id, @PathVariable("name") String name) {

		System.out.println("====index()方法执行====");

		return "index";

	}

}
