springMVC 解决硬编码问题

一、 jdbc.properties
spring dao配置
<!-- 配置 读取properties文件 jdbc.properties -->
<context:property-placeholder location="classpath:jdbc.properties" />

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/crm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

二、 log4j.properties

  • web.xml
<!--使用监听加载log4j的配置文件-->
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>
  • log4j.properties
# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

三、自定义

  • controller
//注解在成员变量上
@Value("${fromType.code}")
private String fromTypeCode;     
  • resource.properties 文件
fromType.code=002
  • springmvc.xml
<!-- springmvc配置  -->
<context:property-placeholder location="classpath:resource.properties" />

待续。。。。。环境配置
