Maven 要点

1、maven自定义标签，引用方式为${file.encoding}

<properties>  
    <file.encoding>UTF-8</file.encoding>  
</properties>

2、剔除依赖传递exclusions

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
    <exclusions>
        <exclusion>
            <artifactId>commons-logging</artifactId>
            <groupId>commons-logging</groupId>
        </exclusion>
    </exclusions>
</dependency>

未完，待补充
