1.springmvc基本配置
导入jar包
配置xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name></display-name>
<welcome-file-list>
<welcome-file>Login.jsp</welcome-file>
</welcome-file-list>
<!-- 前端控制器 -->
<servlet>
<servlet-name>springm</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:sprinmvc-servlet.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springm</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- 过滤器的配置 -->
<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>
</web-app>
其中,配置前端控制器,关联springmvc-servlet.xml文件,设置拦截请求;监听器可配置也可不配置,用于拦截所有页面,处理编码,防止中文乱码,统一改成utf-8编码。
配置springmvc-servlet.xml文件 :配置Springmvc自动扫描器,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:mvc="http://www.springframework.org/schema/mvc"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd

http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
<!-- 配置处理器 -->
<!-- <bean id="login" name="/login.do" class="com.controller.LoginController"></bean>-->
<!-- 配置普通类 -->
<!-- <bean id="annotationLogin" class="com.controller.AnnotationLoginController"></bean>-->
<!-- 注册注解驱动 -->
<!-- <mvc:annotation-driven/>-->
<!-- <mvc:annotation-driven/> -->
<!-- 配置springmvc的自动扫描器 -->
<context:component-scan base-package="com.controller"/>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/"></property>
<!-- 后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
注意:配置了自动扫描器,就不需要配置处理器和普通类了,自动扫描器会自动扫描包下的所有类,识别携带注解的:使用时,将包下的类用注解声明为Controller 注意路径匹配
@Controller
public class HelloWordController {
@RequestMapping("/helloword")
public String helloword(Model model){
model.addAttribute("message","StringMvc 来了");
return "helloword";
}
return 返回的页面名,通过视图解析器进行路径匹配。
这样,springmvc简单的配置就完成了。可以通过前端页面进行一个简单的跳转实验
<a href="helloword.do">springmvc</a>
