2. aop拦截器

3. logback配置
logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!-- 修改一下路径-->
<property name="PATH" value="/log/imooc/course/business"></property>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<!-- <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %highlight(%-5level) %blue(%-50logger{50}:%-4line) %green(%-8X{UUID}) %msg%n</Pattern>-->
<Pattern>%d{ss.SSS} %highlight(%-5level) %blue(%-30logger{30}:%-4line) %green(%-8X{UUID}) %msg%n</Pattern>
</encoder>
</appender>
<appender name="TRACE_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

4. 测试类
package com.course.business.controller.admin;
import com.course.server.dto.ChapterDto;
import com.course.server.dto.PageDto;
import com.course.server.dto.ResponseDto;
import com.course.server.service.ChapterService;
import com.course.server.util.ValidatorUtil;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
@RestController
@RequestMapping("/admin/chapter")
public class ChapterController {
// 业务标识
public static final String BUSINESS_NAME = "大章";
@Resource
private ChapterService chapterService;
//http://127.0.0.1:9002/business/admin/chapter/list
@PostMapping("/list")
public ResponseDto list(@RequestBody PageDto pageDto) {
ResponseDto responseDto = new ResponseDto();
chapterService.list(pageDto);
responseDto.setContent(pageDto);
return responseDto;
}
@PostMapping("/save")
public ResponseDto save(@RequestBody ChapterDto chapterDto) {
// 保存校验
ValidatorUtil.require(chapterDto.getName(), "名称");
ValidatorUtil.require(chapterDto.getCourseId(), "课程ID");
ValidatorUtil.length(chapterDto.getCourseId(), "课程ID", 1, 8);
ResponseDto responseDto = new ResponseDto();
chapterService.save(chapterDto);
responseDto.setContent(chapterDto);
return responseDto;
}
@DeleteMapping("/delete/{id}")
public ResponseDto delete(@PathVariable String id) {
ResponseDto responseDto = new ResponseDto();
chapterService.delete(id);
return responseDto;
}
}
5. 关键点
LogAspect中日志key “UUID”要和logback.xml中的获取的key UUID要一致，UUID生成规则自定义
6. 效果图
