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

2021-08-20 02:37:58

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

       <artifactId>slf4j-api</artifactId>

       <version>${slf4j.version}</version>

     </dependency>

web.xml 中将日志部分的配置替换为

 <!-- 日志过滤器 -->

     <filter>

         <filter-name>log4jServletFilter</filter-name>

         <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>

     </filter>

     <filter-mapping>

         <filter-name>log4jServletFilter</filter-name>

         <url-pattern>/*</url-pattern>

     </filter-mapping>

     <!-- 日志监听 -->

     <listener>

         <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>

     </listener>

添加新的log4j2.xml 配置文件

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

 <Configuration status="OFF" monitorInterval="1800">

     <properties>

         <property name="LOG_HOME">/WEB-INF/logs</property>

         <property name="FILE_NAME">finance-pay</property>

     </properties>

             <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>

         </Console>

         <RollingFile name="running-log" fileName="${LOG_HOME}/${FILE_NAME}.log"

                      filePattern="${LOG_HOME}/$${date:yyyy-MM}/${FILE_NAME}-%d{yyyy-MM-dd}-%i.log.gz"

                      immediateFlush="true">

             <PatternLayout

                     pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [%thread][%file:%line] - %msg%n"/>

             <Policies>

                 <TimeBasedTriggeringPolicy/>

                 <SizeBasedTriggeringPolicy size="15 MB"/>

             </Policies>

             <DefaultRolloverStrategy max="20"/>

         </RollingFile>

     </Appenders>

     <Loggers>

         <Root level="info">

             <!-- 输入到文件-->

             <AppenderRef ref="running-log"/>

             <!-- 输入到控制台-->

             <AppenderRef ref="Console"/>

         </Root>

     </Loggers>

 </Configuration>

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。
