logback配置学习

主要模块：Logback-access     Logback-calssic    Logback-core

主要标签：logger    appender     layout

1.在idea中引入依赖

<!--logback日志相关包-->
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.7.25</version>
</dependency>
<dependency>
  <groupId>ch.qos.logback</groupId>
  <artifactId>logback-access</artifactId>
  <version>1.2.3</version>
</dependency>
<dependency>
  <groupId>ch.qos.logback</groupId>
  <artifactId>logback-core</artifactId>
  <version>1.2.3</version>
</dependency>
<dependency>
  <groupId>ch.qos.logback</groupId>
  <artifactId>logback-classic</artifactId>
  <version>1.2.3</version>
</dependency>

2.编写logback.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<configuration  scan="true" scanPeriod="60 seconds" debug="false">
    <!--定义参数常量-->
    <!--TRACE<DEBUG<INFO<WARN<ERROR-->
    <property name="log.level" value="debug" />
    <property name="log.maxHistory" value="30"/>
    <property name="log.filePath" value="${catalina.base}/logs/webapps"/>
    <property name="log.pattern"
              value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thead] %-5level %logger{50} - %msg%n"/>
    <!--appender告诉输出的媒介-->
    <!--控制台设置-->
    <appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${log.pattern}</pattern>
        </encoder>
    </appender>
    <!--DEBUG-->
    <appender name="debugAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--文件路径-->
        <file>${log.filePath}/debug.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--文件名称-->
            <fileNamePattern>${log.filePath}/debug/debug.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
            <!--文件最大保存历史数量-天-->
            <maxHistory>${log.maxHistory}</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${log.pattern}</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>DEBUG</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!--INFO-->
    <appender name="infoAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--文件路径-->
        <file>${log.filePath}/info.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--文件名称-->
            <fileNamePattern>${log.filePath}/info/info.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
            <!--文件最大保存历史数量-天-->
            <maxHistory>${log.maxHistory}</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${log.pattern}</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!--ERROR-->
    <appender name="errorAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--文件路径-->
        <file>${log.filePath}/error.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--文件名称-->
            <fileNamePattern>${log.filePath}/error/error.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
            <!--文件最大保存历史数量-天-->
            <maxHistory>${log.maxHistory}</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${log.pattern}</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <logger name="com.hyx" level="log.level" additivity="true">
        <appender-ref ref="debugAppender"/>
        <appender-ref ref="infoAppender"/>
        <appender-ref ref="errorAppender"/>
    </logger>
    
    <root level="info">
        <appender-ref ref="consoleAppender"/>
    </root>
</configuration>

3.测试

@Test
public void memcachedTest(){
    log.info("====start===");
    long startTime = System.currentTimeMillis();
    List list = studentService.selectAll();
    System.out.println(list);
    long endTime = System.currentTimeMillis();
    log.info("执行时间：[{}ms]",endTime-startTime);
    log.info("====end====");
}

java中应用redis

使用redis的流程介绍

4.1 导入redis客户端依赖

<!--redis客户端：Jedis-->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>

4.2 引入spring中对redis连接池相关配置配置

redis.properties

redis.hostname=localhost
redis.port=6379
redis.database=0
redis.pool.maxActive=100
redis.pool.maxIdle=20
redis.pool.maxWait=3000
redis.pool.testOnBorrow=true

application.xml中配置

<!-- Redis连接池的设置 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<!-- 控制一个pool可分配多少个jedis实例 -->
   <property name="maxTotal" value="${redis.pool.maxActive}" />
<!-- 连接池中最多可空闲maxIdle个连接 ，这里取值为20，表示即使没有数据库连接时依然可以保持20空闲的连接，而不被清除，随时处于待命状态。 -->
   <property name="maxIdle" value="${redis.pool.maxIdle}" />
<!-- 最大等待时间:当没有可用连接时,连接池等待连接被归还的最大时间(以毫秒计数),超过时间则抛出异常 -->
   <property name="maxWaitMillis" value="${redis.pool.maxWait}" />
<!-- 在获取连接的时候检查有效性 -->
   <property name="testOnBorrow" value="${redis.pool.testOnBorrow}" />
</bean>

<!-- 创建Redis连接池，并做相关配置 -->
<bean id="jedisWritePool" class="com.hyx.util.JedisPoolWriper"
     depends-on="jedisPoolConfig">
<constructor-arg index="0" ref="jedisPoolConfig" />
<constructor-arg index="1" value="${redis.hostname}" />
<constructor-arg index="2" value="${redis.port}" type="int" />
</bean>

<!-- 创建Redis工具类，封装好Redis的连接以进行相关的操作 -->
<bean id="jedisUtil" class="com.hyx.util.JedisUtil" scope="singleton">
<property name="jedisPool">
<ref bean="jedisWritePool" />
</property>
</bean>
<!-- Redis的key操作 -->
<bean id="jedisKeys" class="com.hyx.util.JedisUtil$Keys" scope="singleton">
<constructor-arg ref="jedisUtil"></constructor-arg>
</bean>
<!-- Redis的Strings操作 -->
<bean id="jedisStrings" class="com.hyx.util.JedisUtil$Strings"
     scope="singleton">
<constructor-arg ref="jedisUtil"></constructor-arg>
</bean>
<!-- Redis的Lists操作 -->
<bean id="jedisLists" class="com.hyx.util.JedisUtil$Lists"
     scope="singleton">
<constructor-arg ref="jedisUtil"></constructor-arg>
</bean>
