一、创建项目
1、新建一个项目名为：springmvc-demo-yuyongqing
右键项目名选择add framework support
2、选择web application
3、配置springmvc
pom.xml
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<dependencies> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version> 4.13 . 2 </version> <scope>test</scope> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-webmvc</artifactid> <version> 5.2 . 13 .release</version> </dependency> <dependency> <groupid>javax.servlet</groupid> <artifactid>servlet-api</artifactid> <version> 2.5 </version> </dependency> <dependency> <groupid>javax.servlet</groupid> <artifactid>javax.servlet-api</artifactid> <version> 4.0 . 1 </version> <scope>provided</scope> </dependency> </dependencies> |
刷新maven后再加入如下图所示代码
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>** /*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/ *.xml</include> </includes> <filtering> false </filtering> </resource> </resources> </build> |
二、配置核心文件
1、
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?xml version= "1.0" encoding= "utf-8" ?> <beans xmlns= "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi= "http://HdhCmsTestw3.org/2001/xmlschema-instance" xmlns:context= "http://HdhCmsTestspringframework.org/schema/context" xmlns:mvc= "http://HdhCmsTestspringframework.org/schema/mvc" xsi:schemalocation="http: //HdhCmsTestspringframework.org/schema/beans http: //HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd http: //HdhCmsTestspringframework.org/schema/context https: //HdhCmsTestspringframework.org/schema/context/spring-context.xsd http: //HdhCmsTestspringframework.org/schema/mvc https: //HdhCmsTestspringframework.org/schema/mvc/spring-mvc.xsd ">
<!-- bean definitions here --> |
2、添加springmvc配置内容
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<!-- 自动扫描包，让指定包下的注解生效,由ioc容器统一管理 --> <context:component-scan base- package = "controller" />
<!-- 1 加载注解驱动 --> <mvc:annotation-driven/> <!-- 2 静态资源过滤 --> <mvc: default -servlet-handler/> <!-- 3 视图解析器 --> <bean id= "internalresourceviewresolver" class = "org.springframework.web.servlet.view.internalresourceviewresolver" > <property name= "prefix" value= "/web-inf/jsp/" /> <property name= "suffix" value= ".jsp" /> </bean> |
3、controller层
新建一个hellocontroller类
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
package controller;
@controller public class hellocontroller {
@requestmapping ( "/hello" ) public string hello(model model){ // model 封装数据 model.addattribute( "msg" , "hello my first spring mvc project" );
// 返回的字符串就是视图的名字 会被视图解析器处理 return "hello" ; } } |
4、jsp
在jsp包下新建hello.jsp
|
1 2 3 4 5 6 7 8 9 |
<%@ page contenttype= "text/html;charset=utf-8" language= "java" %> <html> <head> <title>title</title> </head> <body> ${msg} </body> </html> |
三、web.xml
1、配置前端控制器
|
1 2 3 4 |
<!-- 配置前端控制器 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet- class >org.springframework.web.servlet.dispatcherservlet</servlet- class > |
2、配置初始化参数
|
1 2 3 4 5 |
<!-- 配置初始化参数 --> <init-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value> </init-param> |
3、设置启动级别
|
1 2 3 |
<!-- 设置启动级别 --> <load-on-startup> 1 </load-on-startup> </servlet> |
4、设置springmvc拦截请求
|
1 2 3 4 5 |
<!-- 设置springmvc拦截请求 --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern> / </url-pattern> <!--拦截除.jsp的请求--> </servlet-mapping> |
5、乱码过滤
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<!-- 乱码过滤 --> <filter> <filter-name>encodingfilter</filter-name> <filter- class >org.springframework.web.filter.characterencodingfilter</filter- class > <init-param> <param-name>encoding</param-name> <param-value>utf- 8 </param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> |
6、运行web
打包
file→project structure
删除默认的包
点ok→ok
四、配置tomcat
1、点击 add configuration… 进入运行配置框
2、点 + 选择tomcat server 下的 local
3、点击 configure 选择我们自己的tomcat
五、运行tomcat
在浏览器输入http://localhost:8080/hello
