一、springMVC工程依赖 1.1 pom.xml 依赖配置

<dependencies>
    <!-- SpringMVC -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>5.3.1</version>
    </dependency>

    <!-- 日志 -->

    </dependency>
  </dependencies>

1.2 web.xml

1.3 springMVC.xml 配置

 <context:component-scan base-package="com.example.mvc.controller"/>


    
    <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
        <property name="order" value="1"/>
        <property name="characterEncoding" value="UTF-8"/>
        <property name="templateEngine">
            <bean class="org.thymeleaf.spring5.SpringTemplateEngine">
                <property name="templateResolver">
                    <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">

                        
                        <property name="prefix" value="/WEB-INF/templates/"/>

                        
                        <property name="suffix" value=".html"/>
                        <property name="templateMode" value="HTML5"/>
                        <property name="characterEncoding" value="UTF-8" />
                    bean>
                property>
            bean>
        property>
    bean>

    
    <mvc:default-servlet-handler/>

    
    <mvc:annotation-driven>
        <mvc:message-converters>
            
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="defaultCharset" value="UTF-8" />
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/htmlvalue>
                        <value>application/jsonvalue>
                    list>
                property>
            bean>
        mvc:message-converters>
    mvc:annotation-driven>

1.4 IDEA右边找到不maven工具框

右键pom.xml文件 -> add as maven Project

1.5 IDEA tomcat 日志乱码处理办法

idea.vmoptions 当中添加

-Dfile.encoding=UTF-8
-Dconsole.encoding=UTF-8

1.6 工程HiddenHttpMethodFilter 依赖

<filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <url-pattern>/*
  

1.7 开启对静态资源访问的依赖

    <mvc:default-servlet-handler/>

二、前后端页面跳转传值

页面功能，输入一个字符串，返回其数字部分，并存入mysql数据库，没有找到数字则返回没有数字信息

Controller 类

package com.spring.mvc.controller;

import com.spring.mvc.entity.MyString;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.RequestDispatcher;
import java.sql.SQLException;

@Controller
public class spring1 {
    @RequestMapping("/")
    public String index(){
        return "index";
    }
    @RequestMapping(
            value = { "/target" ,"/target2"}
    )
    public String target(){
        String name="123";
        return "target";
    }
    @RequestMapping("/getNumber")
    public ModelAndView getNumber(@RequestParam("stringname") MyString mystring){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("key",mystring.returnNumber());

        try {
            mystring.insertToSql();
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
       modelAndView.setViewName(index());
        return modelAndView;
    }
}
