基于注解的Spring整合SpringMVC开发流程？

先声明：

我使用maven管理项目

在pom文件中导入远程中央仓库的包（这里仅导入springwebmvc包即可）
（1）给出我的pom.xml

<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.edu.hdu</groupId>  <artifactId>mavenDemo</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>mavenDemo 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>     <!-- spring-webmvc:导入它之后，spring依赖的包会自动被下载。 --><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.9.RELEASE</version></dependency>  </dependencies>  <build>    <finalName>mavenDemo</finalName>    <plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.8</source><target>1.8</target></configuration></plugin></plugins>  </build></project>

（2）在web.xml下的监听器中，加载Spring配置文件applicationContext.xml，因为listener比servle先执行。

<!-- 在监听器里加载Spring配置文件 --><context-param><param-name>contextConfigLocation</param-name><paramvalue>classpath:config/applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

（3）在applicationContext.xml添加组件扫描

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"xmlns:jpa="http://www.springframework.org/schema/data/jpa"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsdhttp://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"><context:component-scan base-package="controller" /><!--spring会扫描带有注解（@controller,@Service,@Repository）的类 --><mvc:annotation-driven /><!-- 启动mvc注解扫描 --></beans>

（3）在web.xml下的servlet中，加载前端控制器的映射文件dispatcherServlet-servlet.xml

<servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/dispatcherServlet-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping>

（4）在dispatcherServlet-servlet.xml中添加映射器和视图解析器。

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"xmlns:jpa="http://www.springframework.org/schema/data/jpa"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsdhttp://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"><!-- 配置映射器与视图解析器 --><beanclass="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean></beans>

（5）在src/main/java下的controller包下的java类中添加注解（@controller，@Resource等等）

package controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class person {@RequestMapping(value="/dream")public String action(){return "happiness";}}

（6）在webapp/WEB-INF/下创建自己要访问的jsp网页，这里【插上一张项目结构图】。
