spring常规配置示例

开发常见配置整理-spring

Spring 的空 XML 格式：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>           

Spring IOC 配置 applicationContext.xml

Spring MVC 配置 spring-mvc.xml

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

根据需要调整 log4j2.xml

    <properties>

    </Appenders>
    <Loggers>

        <!-- <Logger name="com.cssweb.test.app" level="trace" additivity="true">

    -->
    <!--additivity=false 表示不往上继承root，因此没有打印root策略的日志-->
    <!--<logger name="org.springframework.core" level="INFO" additivity="false">-->
    <!--<appender-ref ref="Console"/>-->
    <!--</logger>-->
