【SSM架构】博客系统开发5-搭建SpringMVC
1 项目框架的搭建
ssm架构 = spring + springmvc + mybatis
(1) 包结构
总览,以下是项目的文件骨架,接下来我们需要为项目生成画红框的5个文件
按照图片的目录形式创建文件结构
2 搭建springmvc环境
(1) 建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>com.highcom</groupId>
<artifactId>ssm-blog</artifactId> //这个地方要改成自已的
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<properties>
<spring.version>4.2.0.RELEASE</spring.version>
</properties>
<dependencies>

<build>
<finalName>ssm-blog</finalName>
<plugins>
<plugin>

<configuration>

</configuration>

</project>
(2) 建 spring-mvc.xml
<?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-4.2.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-4.2.xsd">
<!-- 开启自动扫描,把组件纳入spring管理 -->
<context:component-scan base-package="com" />
<!-- 开启注解驱动 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
(3) 配置 web.xml
<?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" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>blog-douyuzhi</display-name>
<!-- 加载spring 容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring/spring-*.xml
</param-value>
</context-param>
<!-- 监听器,用来加载spring容器 -->
<listener>
<listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
</listener>
<!-- springmvc 的前端控制器,作用就是把所有的请求交给spring框架去处理 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
(4) 创建控制层TestController.java
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController
{
@RequestMapping("/test")
public String test(ModelMap m) {
System.out.println("来过控制层....领导接见了我...");
m.put("msg", "我的springmvc流程走通了");
m.put("dog", "我从控制层领回来一只叫tom的狗");
return "index"; //==> /jsp/index.jsp
}
}
(5) 创建index.jsp
在index.jsp中添加:
<body>
<h1> 这是index.jsp</h1>
<hr />
${msg } <br/>
${dog }
</body>
(6) 访问
从浏览器地址栏输入
http://localhost:8080/blog-douyuzhi/test
进行测试,如果能走到 index.jsp 并显示出内容,证明成功
