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"?>

xsi:schemaLocation="

<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.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd

http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd

http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd

http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

http://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 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean

class="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;





@Controller

public 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】。
