Spring-MVC4 + JPA2 + MySql-5.5 + SLF4J + JBoss WildFly-8.1开发环境搭建

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>

	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>

		<!-- 支持文件上传 -->

			<artifactId>commons-fileupload</artifactId>
			<version>1.3.1</version>
		</dependency>
		<dependency>

		<dependency>

			<artifactId>spring-tx</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<!-- hibernate -->
		<dependency>
			<groupId>org.hibernate</groupId>

		</dependency>

		<!-- MySql JDBC Driver -->

			<groupId>mysql</groupId>

		</dependency>

		<!-- AspectJ -->

			<version>${org.aspectj-version}</version>
		</dependency>
		<dependency>
			<groupId>cglib</groupId>
			<artifactId>cglib</artifactId>
			<version>2.2</version>
		</dependency>

		<!-- @Inject -->
		<dependency>
			<groupId>javax.inject</groupId>
			<artifactId>javax.inject</artifactId>
			<version>1</version>
		</dependency>

		<!-- Servlet -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<version>3.0.1</version>
			<scope>provided</scope>

		<dependency>

			<artifactId>slf4j-log4j12</artifactId>
			<version>${slf4jVersion}</version>
		</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"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

	<!-- DispatcherServlet Context: defines this servlet's request-processing 
		infrastructure -->

	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

	<!-- Handles HTTP GET requests for /resources/** by efficiently serving 
		up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />

	<!-- Resolves views selected for rendering by @Controllers to .jsp resources 
		in the /WEB-INF/views directory -->
	<beans:bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value=http://www.mamicode.com/"/WEB-INF/views/" />>
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=http://www.mamicode.com/"System.out" />>
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。
