logback使用

1.添加maven依赖

 <properties>
        <java.version>1.8</java.version>
        <logback.version>1.1.7</logback.version>
 </properties>
       <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>

        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>${logback.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>${logback.version}</version>
        </dependency>

          <resources>
            <resource>
                <filtering>true</filtering>
                <directory>src/main/resources</directory>
                <includes>
                    <include>*.*</include>
                </includes>
            </resource>

            <resource>
                <directory>src/main/resources/</directory>
            </resource>

            <resource>
                <filtering>true</filtering>
                <directory>config/</directory>
                <includes>
                    <include>*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!--将resources目录下的配置文件编译进classes文件，你的配置文件放在哪就加哪个  -->
        </resources>

2.添加配置文件

logback.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!-- scan="true"    当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true。 -->
<!--  scanPeriod="30 seconds"   设置每30秒自动扫描,若没有指定具体单位则以milliseconds为标准(单位:milliseconds, seconds, minutes or hours)  -->
<!-- debug="false"当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。-->
<configuration  scan="true" scanPeriod="30 seconds">
    <!-- 上下文名称  -->
    <contextName>test</contextName>

    <!-- 存放日志文件路径 -->
    <property name="Log_Home" value="D:/存放路径" />

    <!-- ch.qos.logback.core.ConsoleAppender 控制台输出 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

            <pattern>%d{yyyy-MM-dd HH:mm:ss SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
    </appender>

    <!-- DEBUG级别 -->

3.使用

Logger logger = LoggerFactory.getLogger(SpringTaskTest.class);
logger.info("--------------------task1开始--------------------");
