由于面试被问到了Spring4，所以打算把过去Spring3的项目全部升级为Spring4。现将环境搭建过程记录在此。
首先使用Maven Archetype创建项目骨架，执行以下命令：
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-webapp -DarchetypeVersion=1.0 -DgroupId={你的groupId} -DartifactId={你的artifactId} -Dversion=1.0-SNAPSHOT完成后会生成最基本的目录结构，和一个包含了JUnit的pom.xml。这显然是不够的。我们需要自行修改 pom.xml 添加所需依赖：
<properties>
<java-version>1.7</java-version>
<org.aspectj-version>1.7.3</org.aspectj-version>
<spring.version>4.0.1.RELEASE</spring.version>
<slf4jVersion>1.7.7</slf4jVersion>
</properties>

<!-- hibernate -->

</dependency>
<!-- MySql JDBC Driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
<!-- AspectJ -->

</dependency>
<!-- @Inject -->

<!-- Servlet -->

</dependency>
<dependency>

</dependency>
<!-- log4j -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>
</dependency>
</dependencies>然后把 java版本改为1.7：（Spring4最低要求是1.6）
<build> <finalName>shop</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.5.1</version> <configuration> <source>1.7</source> <target>1.7</target> <compilerArgument>-Xlint:all</compilerArgument> <showWarnings>true</showWarnings> <showDeprecation>true</showDeprecation> </configuration> </plugin> </plugins> </build>
创建如下图所示的目录结构：
下面是各个配置文件的完整内容。
通过 jboss-deployment-structure.xml 命令JBoss不要使用内置的Log系统：
<?xml version="1.0" encoding="UTF-8"?> <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2"> <deployment> <exclude-subsystems> <subsystem name="logging" /> </exclude-subsystems> </deployment> </jboss-deployment-structure>
通过 shop-ds.xml 在部署时动态向JBoss注册数据源：
<?xml version="1.0" encoding="UTF-8"?> <datasources xmlns="http://www.jboss.org/ironjacamar/schema"> <datasource jndi-name="java:jboss/datasources/shop" enabled="true" use-java-context="true" pool-name="codeschooldb"> <connection-url>jdbc:mysql://localhost:3306/shop?characterEncoding=utf-8</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <driver>mysql</driver> <security> <user-name>root</user-name> <password>111111</password> </security> </datasource> </datasources>
由于我们使用 Servet 3.0，所以web.xml也要相应的升级：
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>
<!-- spring -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>通过Spring配置文件 servlet-context.xml 配置JPA, Hibernate，数据源JNDI查找等内容：
<?xml version="1.0" encoding="UTF-8"?>

<context:component-scan base-package="cn.fh.shop" />
</beans:beans>
src/main/resources/log4j.xml 配置如下：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- Appenders --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p: %c - %m%n" /> </layout> </appender> <!-- Application Loggers --> <logger name="cn.fh.spring"> <level value="info" /> </logger> <!-- 3rdparty Loggers --> <logger name="org.springframework.core"> <level value="info" /> </logger> <logger name="org.springframework.beans"> <level value="info" /> </logger> <logger name="org.springframework.context"> <level value="info" /> </logger> <logger name="org.springframework.web"> <level value="info" /> </logger> <!-- Root Logger --> <root> <priority value="debug" /> <appender-ref ref="console" /> </root> </log4j:configuration>
至此一切OK。执行 mvn clean install 构建工程，将 shop.war 复制到 JBoss 部署目录下即可。
