一步一步实现Spring4 + Hibernate4 + Freemarker2 的注解驱动开发（一. 环境搭建）

一 环境搭建

1.JDK安装

   下载并安装JDK 6以上版本(本事例采用的JDK8，编写文档时，jdk8为测试版)

2.开发工具安装

   下载并安装Spring的Eclipse集成开发工具STS最新版本

   STS下载地址：http://spring.io/tools/sts/all

   也可以直接使用eclipse

3.数据库安装

   下载并安装MySQL数据库

2.在STS中创建新spring项目，项目模板：Spring MVC Project

3.创建项目完成后，设置项目属性，在build中，更改jre为1.8版本

   编辑maven配置文件pom.xml，设置spring 版本为4.0.2(此文档编写时最新版本)，其它所依赖包也可设置为更新的版本，保存pom.xml。

   

 编辑pom.xml文件，引入需要使用的依赖包，测试项目的pom.xml文件如下

<?xml version="1.0" encoding="UTF-8"?><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>cn.toncen</groupId><artifactId>cms</artifactId><name>cms</name><packaging>war</packaging><version>1.0.0-BUILD-SNAPSHOT</version><properties><java-version>1.8</java-version><org.springframework-version>4.0.2.RELEASE</org.springframework-version><org.aspectj-version>1.7.4</org.aspectj-version><org.slf4j-version>1.7.6</org.slf4j-version></properties><dependencies><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${org.springframework-version}</version><exclusions><!-- Exclude Commons Logging in favor of SLF4j --><exclusion><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${org.springframework-version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${org.springframework-version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${org.springframework-version}</version></dependency><!-- AspectJ --><dependency><groupId>org.aspectj</groupId><artifactId>aspectjrt</artifactId><version>${org.aspectj-version}</version></dependency><!-- Hibernate --><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>4.3.4.Final</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.29</version><scope>runtime</scope></dependency><!-- Logging --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${org.slf4j-version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>jcl-over-slf4j</artifactId><version>${org.slf4j-version}</version><scope>runtime</scope></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${org.slf4j-version}</version><scope>runtime</scope></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version><exclusions><exclusion><groupId>javax.mail</groupId><artifactId>mail</artifactId></exclusion><exclusion><groupId>javax.jms</groupId><artifactId>jms</artifactId></exclusion><exclusion><groupId>com.sun.jdmk</groupId><artifactId>jmxtools</artifactId></exclusion><exclusion><groupId>com.sun.jmx</groupId><artifactId>jmxri</artifactId></exclusion></exclusions><scope>runtime</scope></dependency><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.20</version></dependency><!-- @Inject --><dependency><groupId>javax.inject</groupId><artifactId>javax.inject</artifactId><version>1</version></dependency><!-- Servlet --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.1</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!-- Test --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency></dependencies><build><plugins><plugin><artifactId>maven-eclipse-plugin</artifactId><version>2.9</version><configuration><additionalProjectnatures><projectnature>org.springframework.ide.eclipse.core.springnature</projectnature></additionalProjectnatures><additionalBuildcommands><buildcommand>org.springframework.ide.eclipse.core.springbuilder</buildcommand></additionalBuildcommands><downloadSources>true</downloadSources><downloadJavadocs>true</downloadJavadocs></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><source>1.7</source><target>1.7</target><compilerArgument>-Xlint:all</compilerArgument><showWarnings>true</showWarnings><showDeprecation>true</showDeprecation></configuration></plugin><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.2.1</version><configuration><mainClass>org.test.int1.Main</mainClass></configuration></plugin></plugins></build></project>

Maven 会自动从网络下载程序所依赖版本的jar包
