基于springBoot下搭建日志框架

1. 日志框架的选择：（这两个框架，springBoot已经整合，无需引入jar包）

 2. 在resources目录下配置logback-spring.xml

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>
<!--控制台的日志输出的配置-->
    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<!--        输出日志的格式设置-->
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d - %msg%n
            </pattern>
        </layout>
    </appender>
<!--输出除警告级别外的日志到本地文件下，并且实现每日生成一个日志文件-->
    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!--        日志级别过滤器-->
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
<!--            以下三行表示当匹配到error级别的日志时拒绝写入日志，其余级别允许写入-->
            <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>F:sellLoginfo.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

<!--只输出警告级别的日志到本地文件下，并且实现每日生成一个日志文件-->
    <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>F:sellLogerror.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

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

</configuration>

3. 在springBoot启动类添加日志相应的对象（本例使用了junit测试，与在启动类配置一样）

package com.yzy.sell;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;


@RunWith (SpringRunner.class)
@SpringBootTest
public class SellApplicationTests {
  private final Logger log= LoggerFactory.getLogger(SellApplicationTests.class);
    @Test
    public void test1() {
        String name = "yzy";
        String password = "123456";
        log.debug("debug...");
        log.info("name: " + name + " ,password: " + password);
        log.info("name: {}, password: {}", name, password);
        log.error("error...");
        log.warn("warn...");
    }
}
