  • SSM（Spring5.x+Mybatis3）框架搭建【解决日志问题】（Github源码）

    闲来无事，用SSM写个小东西，发现spring已经迭代到5.x了，遂出此文，希望对各位同学有些许帮助。

    IDE：idea

    OS：windows

    源代码：https://github.com/JHeaven/ssm-easy-demo

    直接用模板新建MAVEN项目，看清楚是哪个webapp，别选错了

    相关信息，略

    加上这个参数，不然创建项目的时候巨慢

    稍等，至如下画面，即完成maven 基本web项目创建

    现在的项目结构是这样的

    添加基础的包结构，先这样，需要什么之后再加

    下面我们导包，即配置pom文件

    注意oracle 的包需要自己打进本地仓库

    基础配置完成，接下来，要添加请求控制和数据库交互，完成之后如下图（具体代码贴到Github了，自取，不再一一贴出）：

    完成以上，项目已经可以跑了。

    BUT!!!!!!!!!!!细心的同学可能已经发现了端倪，日志完全没动静！

    控制台输出

    log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
    log4j:WARN Please initialize the log4j system properly.
    log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

    需要注意的是spring5中貌似已经移除了 org.springframework.web.util.Log4jConfigListener，如果不配这个，日志没办法输出

     降级到4.3.20的文档

    https://docs.spring.io/spring/docs/4.3.20.RELEASE/javadoc-api/

    spring4.2.1 声明将弃用这个类，并且更倾向于使用log4j2

    那我们接下来完全引入新的log4j2的包和slf4j桥接包

    web.xml 中将日志部分的配置替换为

     1 <!-- 日志过滤器 -->
 2     <filter>
 3         <filter-name>log4jServletFilter</filter-name>
 4         <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
 5     </filter>

 7         <filter-name>log4jServletFilter</filter-name>
 8         <url-pattern>/*</url-pattern>

11     <!-- 日志监听 -->
12     <listener>
13         <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
14     </listener>

     添加新的log4j2.xml 配置文件

     1 <?xml version="1.0" encoding="UTF-8"?>

    重启，无效，将log4j2.xml放到resources根目录下

    成功

    太难受了。。。怎么能允许单个xml在外面孤军奋战呢。。。根据之前的经验，log4j2没法简单的指定配置文件路径，揪一下文档把

    翻过来就是说： Log4j将检查名为"log4j.configurationFile"系统属性，如果这个属性有值，将尝试使用与文件扩展名（这里是XML）匹配的ConfigurationFactory方法加载配置。

    所谓System.property，其实就是在JVM启动的时候加上参数，这样显然也太麻烦了。。。

    另外找路子，打开log4j-core的jar包，检索之后发现有这么个类 Configurator

    参数皆为静态变量，尝试直接调用这个方法，先把这个configLocation 设置进去。

    成功。
