在resourse下面建立一个log4j.properties

log4j.properties

    ### 设置###
    log4j.rootLogger = INFO,stdout
     
    ### 输出信息到控制抬 ###
    log4j.appender.stdout = org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout = org.apache.log4j.PatternLayout

    log4j.category.org.springframework.beans.factory=DEBUG

MesasageService 类

    package hello;
     
    //去掉注解
     
    public class MesasageService {
        public MesasageService() {
            super();
