java运行提示没有 org/slf4j/LoggerFactory 或者 log4j

问题描述

Exception in thread “main” java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

解决办法

在pom.xml里面添加对应的配置, 将jar包大包进去

	<dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.7</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.7</version>
    </dependency>

或者, 运行的时候, 指定java class path, (可能有很多包依赖没有打包)
CLASSPATH=…
java -cp …
