日志文件在開發(fā)中至關(guān)重要，是日后查看異常，排查bug的重要依據(jù)。
像我大安卓，也會有日志記錄類Thread.UncaughtExceptionHandler進(jìn)行錯誤異常日志記錄奄抽，并回傳后臺進(jìn)行匯總報告，或者是使用Bugly 來進(jìn)行異常日志捕獲甩鳄，那么服務(wù)器也是會有類似的逞度。
而我們使用的是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>
        <!--滾動策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路徑-->
            <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>
        <!--滾動策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路徑-->
            <fileNamePattern>log/tomcat/sell/error.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <root level="info">
        <appender-ref ref="consoleLog" />
        <appender-ref ref="fileInfoLog" />

配置方法

配合 插件

插件

在使用的類前面加入注解：

@Slf4j

具體如下：

@RestController
@RequestMapping("api/home")
@Api(value = "首頁模塊")
@Slf4j
public class AwayController {
...
}

使用方法

    @GetMapping("shopList")
    @ApiOperation("獲取店鋪列表")
    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());

就是調(diào)用了log方法
