spring mvc基础环境thymeleaf模板引用（一）

 

spring mvc基础环境配置

1.引入必要的依赖 .

2.配置springmvc

• web.xml配置 默认的 DispatcherServlet
• classPath根目录创建对应的spring-mvc配置文件

3.写一个，测试类

 

1. pom.xml 文件引入必要的依赖：

（spring-webmvc引用即可，它可以再找上级依赖）

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

    <!-- Spring5和Thymeleaf整合包 -->
    <dependency>
      <groupId>org.thymeleaf</groupId>
      <artifactId>thymeleaf-spring5</artifactId>
      <version>3.0.12.RELEASE</version>
    </dependency>

2.配置 spring-mvc.xml 配置文件 （可以在resources建立，编译后到根目录）

    <!--扫描组件-->
    <context:component-scan base-package="com.cc8w.controller"></context:component-scan>


    <!--  开启mvc的注解驱动，此时即便配置了 view-controller，controller层的控制器方法的请求映射也不会失效 -->
    <mvc:annotation-driven/>

    <!--配置处理器映射器-->
    <!--spring 3.1版本之前-->
    <!--<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>-->
    <!--spring 3.1版本之后-->
    <!--<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>-->

    <!--配置处理器适配器-->
    <!--spring 3.1版本之前-->
    <!--<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>-->
    <!--spring 3.1版本之后-->
    <!--<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>-->


    <!--配置视图解析器-->
    <!--bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean-->

    <!--配置视图解析器-->
    <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">

                        <!-- 视图前缀 -->
                        <property name="prefix" value="/WEB-INF/templates/"/>

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

 

web.xml配置默认的 Servlet

<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
  <servlet>
    <servlet-name>springDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <!-- Map all requests to the DispatcherServlet for handling -->
  <servlet-mapping>
    <servlet-name>springDispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

 

3.试一下

package com.cc8w.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("index")
public class IndexController {

    @RequestMapping("index01")
    public String index01() {
        return "index01";
    }
    
    
}
