Java程序使用Logback最新版本日志框架_java.lang.string ch.qos.logback.core.util.envutil.

版本信息

logback

1.3.0-alpha4

slf4j

1.8.0-beta2

现在Logback框架最新版本为1.3.0-alpha4，而依赖的slf4j的版本也为最新的版本1.8.0-beta2.

Maven依赖

Java开发jar包依赖管理现在主流都是用Maven进行依赖管理，那么开发使用Logback日志框架，只是引入下面依赖即可

1. 在Maven项目pom.xml配置文件properties中添加下如版本信息

      <slf4j.version>1.8.0-beta2</slf4j.version>
      <logback.version>1.3.0-alpha4</logback.version>

2. 在Maven项目pom.xml配置文件repositories中添加依赖

       <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>${logback.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>${logback.version}</version>
        </dependency>

Logback配置文件

配置logout不仅仅需要依赖包，还需要在resources添加配置文件logback.xml,废话不多说，下面是比较完整的各级别的日志记录配置, 注意查看其中的注解

<configuration>
 
    <!-- 日志文件存储在执行目录同级的logs目录下-->
    <property name="PROJECT_HOME" value="${user.dir}/../logs"/>
