SSM框架配置文件详解

SSM框架配置文件详解

在SSM项目当中，所需要的配置文件总共有以下三个：

①web.xml ②applicationContext.xml ③springmvc.xml

以及两个properties文件jdbc.properties和log4j.properties

1.web.xml

web.xml是ssm项目当中最重要的一个配置文件，当服务启动时会首先加载web.xml这个文件，里面包括了对前端控制器、字符编码的配置

案例：

<web-app

5.jdbc.properties(可有可没有，如果没有，直接在applicationContext.xml中配置，如果有的话，则需要在applicationContext.xml中引入)

mysql

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/c2009
user=root
password=123456

DBPool

initialPoolSize=30
minPoolSize=10
maxPoolSize=100
acquireIncrement=5
maxStatements=1000
maxStatementsPerConnection=10
