1. 導入jar包

1. commons
2. apache-log4j-1.2.17
3. mysql-connector-java-5.1.46
4. mybatis-3.4.6+mybatis-spring-1.3.2

  <!-- 使用log4j記錄日誌信息 -->
  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
  </context-param>
  
  <!-- 使用${SMBMS_C11_01.root }動態獲取項目根目錄 -->
  <context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>SMBMS_C11_01.root</param-value>
  </context-param>
  
  <!-- Web容器啓動時自動裝配log4j的配置信息 -->
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>
  
  <!-- Web容器啓動時自動裝配Spring applicationContext.xml的配置信息 -->
  <listener>
</web-app>

2. database.properties+log4j.properties
3. mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
	<settings>
		<setting name="lazyLoadingEnabled" value="false" />
