SpringBoot（三） logback配置
日志文件在开发中至关重要，是日后查看异常，排查bug的重要依据。 像我大安卓，也会有日志记录类 Thread.UncaughtExceptionHandler 进行错误异常日志记录，并回传后台进行汇总报告，或者是使用**Bugly** 来进行异常日志捕获，那么服务器也是会有类似的。 而我们使用的是logback
使用
配置文件：logback-spring.xml
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>
%d - %msg%n
</pattern>
</layout>
</appender>
<appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>DENY</onMatch>
<onMismatch>ACCEPT</onMismatch>
</filter>
<encoder>
<pattern>
%msg%n
</pattern>
</encoder>
<!--滚动策略-->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--路径-->
<fileNamePattern>log/tomcat/sell/info.%d.log</fileNamePattern>
</rollingPolicy>
</appender>
<appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
<encoder>
<pattern>
%msg%n
</pattern>
</encoder>
<!--滚动策略-->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--路径-->
<fileNamePattern>log/tomcat/sell/error.%d.log</fileNamePattern>
</rollingPolicy>
</appender>
<root level="info">
<appender-ref ref="consoleLog" />
<appender-ref ref="fileInfoLog" />
<appender-ref ref="fileErrorLog" />
</root>
</configuration>

与application同级
配置方法
配合 插件
在使用的类前面加入注解：
@Slf4j
具体如下：
@RestController
@RequestMapping("api/home")
@Api(value = "首页模块")
@Slf4j
public class AwayController {
...
}
使用方法
@GetMapping("shopList")
@ApiOperation("获取店铺列表")
public ResultVO shopList(@RequestParam(value = "page", defaultValue = "0") Integer page,
@RequestParam(value = "size", defaultValue = "10") Integer size) {
Sort orders = new Sort(Sort.Direction.ASC, "id");
PageRequest pageRequest = new PageRequest(page, size, orders);
Page<Shop> shopPage = shopService.findShopList(pageRequest);
List<ShopResultVo> shopResultVos = shopPage.getContent()
.stream()
.map(shop -> {
ShopResultVo shopResultVo = new ShopResultVo();
List<Discount> discounts = discountService.findAllByBelongingId(shop.getId());
BeanUtils.copyNonNullProperties(shop, shopResultVo);
shopResultVo.setDiscounts(discounts);
return shopResultVo;
}).collect(Collectors.toList());
log.error("shopResultVos is {}",shopResultVos.toString());
return ResultVoUtils.success(shopResultVos);
}
其中
log.error("shopResultVos is {}",shopResultVos.toString());
就是调用了log方法
正文到此结束
