log4j 和slf4j的 类冲突解决

1. 检查 log4j 和slf4j的冲突

 

public class Log4jTest {

	public static void main(String[] args) {
		try {
			Class.forName("org.slf4j.impl.Log4jLoggerFactory");
		} catch (ClassNotFoundException e) {
			System.out.println(e.getMessage());
		}

		try {
			Class.forName("org.apache.log4j.Log4jLoggerFactory");
		} catch (ClassNotFoundException e) {
			System.out.println(e.getMessage());
		}
	}
}
