J2EE maven pom.xml常用的jar包

新建一个maven webapp工程，默认的pom.xml文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>ms</groupId>
  <artifactId>springLearn</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>springLearn Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>springLearn</finalName>
  </build>
</project>

常用的配置：

<properties>
<spring.version>3.1.3.RELEASE</spring.version>
<junit.version>4.10</junit.version>
<quartz.version>2.2.1</quartz.version>
 

<servlet.version>3.0.1</servlet.version>
<jsp.version>2.1</jsp.version>
<jstl.version>1.2</jstl.version>

<aspectj.version>1.6.10</aspectj.version>

<jdbc.groupId>mysql</jdbc.groupId>
<jdbc.artifactId>mysql-connector-java</jdbc.artifactId>
<jdbc.version>5.1.22</jdbc.version>

<log4j.version>1.2.17</log4j.version>

<commons.io.version>2.4</commons.io.version>
<slf4j.version>1.6.1</slf4j.version>
</properties>

mysql的jdbc driver的maven依赖

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<version>5.1.25</version>
</dependency>

加slf4j

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.2</version>
</dependency>

加json:

<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.2.4</version>
</dependency>

<dependency>
<groupId>net.sf.json-lib</groupId>
<artifactId>json-lib</artifactId>
<version>2.1</version>
<classifier>jdk15</classifier>
</dependency>

json-lib是需要区分jdk版本的，pom.xml中的配置应加上<classifier>标签，如用jdk15.


加commons-io

<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>

 加quartz：

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3</version>
</dependency>

加apache common lang：

经常用到类似的： ReflectionToStringBuilder.toString(token, ToStringStyle.MULTI_LINE_STYLE))

要加common lang

    <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.1</version>
        </dependency>
        

Apache Commons包估计是Java中使用最广发的工具包了，很多框架都依赖于这组工具包中的一部分，它提供了我们常用的一些编程需要，但是JDK没能提供的机能，最大化的减少重复代码的编写。 

http://commons.apache.org/ 


1)Commons Lang是对JDK中java.lang包的补充，提供了各种各样的Utilities工具类，这里说说最常用的几个工具类。 

版本：commons-lang3-3.1.jar
