1.新建maven项目
新建项目报错是因为缺少web.xml文件
右键项目名 找到“”java EE Tools“”
会自动生成一个web.xml文件
2.根据这模板创建文件
3.在pom.xml文件中添加
<!--集成spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.13.RELEASE</version>
</dependency>
<!--配置webmvc -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.13.RELEASE</version>
</dependency>
4.在web.xml文件中添加以下数据
<!-- 配置DispatcherServlet -->
<servlet>
<servlet-name>ssm1</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 自定义servlet.xml配置文件的位置和名称,默认为WEB-INF目录下, 名称为[<servlet-name>]-servlet.xml,此处不定义,则为ssm1.xml -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ssm1</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
5.在springmvc-servlet.xml文件中添加
<?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:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
<!-- 让扫描spring扫描这个包下所有的类,让标注spring注解的类生效 -->
<context:component-scan base-package="com.lianxi" />
<!-- 开启注解 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/views/"></property>
<!-- 后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
<!--释放静态资源 -->
<mvc:default-servlet-handler />
6.在webapp下创建index.jsp
<a href="testSpringMVC">测试springmvc</a><b/>
<a href="testSpring">测试spring</a><b/>
<a href="testMybatis">测试mybatis</a><b/>
7.在UserController中写测试(记得在加@Controller,不然扫不到)
@RequestMapping("/testSpringMVC")
public ModelAndView 测试springmvc是否正常() {
System.out.println("这是springmvc测试");
return null;
}
8.启动项目访问http://localhost:8080/ssm/index.jsp
9.成功后在web.xml文件中添加
<!-- 加载spring核心文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-context.xml</param-value>
</context-param>
<!--中文乱码 -->
<filter>
<filter-name>CharacterEncodingFilter</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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
10.在spring-context.xml文件中添加
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
