springmvc简单使用

Posted 2022-09-29 1556553526qq-com

1.创建一个web工程

2.导入所需的jar包

 

3.配置文件中的DispatcherServlet，由于已经安装了插件，所以只需通过快捷键alt+/即可

 

 

<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:springmvc-annotation.xml</param-value>
         </init-param>
     </servlet>
     <servlet-mapping>
         <servlet-name>springMVC</servlet-name>
         <url-pattern>*.do</url-pattern>
     </servlet-mapping>

4.创建一个配置文件里classpath后的xml文件（插件可直接插入此类xml），并进行包扫描，打开注释驱动以及师徒解析器的编写

<?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">
    <context:component-scan base-package="com.zhiyou.zt.annotation"></context:component-scan>
    <mvc:annotation-driven />
    <mvc:default-servlet-handler/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

5.创建一个包扫描下的包，通过注释@进行操作

package com.zhiyou.zt.annotation;

import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.zhiyou.zt.bean.Users;

@Controller
@RequestMapping("/user")
public class my 
    
        

6.接受参数，如果接收的是单独的参数，方法的参数列表对应的名字必须与传过来的名字一致，如果为对象，则必须与实体类属

 

 

 

 

 

 7.Controller如何进行重定向跳转加入redirect：即可

 

 8.解决静态资源的映射（springmvc.xml加入即可）

<mvc:default-servlet-handler/>
