一些整理：

官网 - http://projects.spring.io/spring-framework/
官方文档：

正式开始：

参考：

  • 导入 jar 包 / maven


commons-logging - Apache提供的第三方日志模块 - 自动搜索并使用Log4j
其他各包的解释 - spring各模块-俯视图

或 pom.xml

  • web.xml
    粘贴文件头 
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

在导入文件头后,能直接生成 DispatcherServlet 配置 - ： 没有提示的话 可以设置本地 schemalocation,参考

最后改成这样：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
    
    <!-- 配置 DispatcherServlet -->
	<servlet><!-- The front controller of this Spring Web application, responsible for handling all application requests -->
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 配置 DispatcherServlet 的一个初始化参数: 配置 SpringMVC 配置文件的位置和名称 -->
		<!-- 也可以不通过 contextConfigLocation 来配置 SpringMVC 的配置文件，而使用默认的 默认的配置文件为: /WEB-INF/<servlet-name>-servlet.xml -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>
  • 添加 springmvc.xml 文件

没有装 spring 插件的，直接复制下面、或 直接下载安装使用 sts

<?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">


</beans>
  • 写请求处理器

创建类

springmvc.xml 添加

<!-- 配置指定扫描的包 -->
<context:component-scan base-package="spring.mvc" />

类添加注解

@Controller
public class HelloWorld {

	
	@RequestMapping("/helloworld")
	public String hello() {
		System.out.println("hello world");
		return "success" ; 
	}
	
}

springmvc.xml 添加

<!-- 配置视图解析器: 如何把handler方法返回解析为实际的物理视图 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/views/"></property>
	<property name="suffix" value=".jsp"></property>
</bean>

添加jsp 页面
