第二步：编写配置类
package com.iflytek.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.thymeleaf.spring5.SpringTemplateEngine;//此处及下面两行如果报错，就是”spring5“版本不对，你可以点击进去查看实际版本然后修改
import org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver;
import org.thymeleaf.spring5.view.ThymeleafViewResolver;
import org.thymeleaf.templateresolver.ITemplateResolver;
/**
* 主要配置多视图实现的视图解析器相关bean实例,将该视图解析器注册到容器中
*
* 其实关键点在于两个：
* 1、配置order属性:视图解析器优先级问题（就是决定先使用哪个解析器来解析视图）
* 2、配置viewnames属性（配置对应的视图解析器解析哪些格式的视图）
*/
@Configuration
public class ViewResolverConfiguration {
@Configuration//用来定义 DispatcherServlet 应用上下文中的 bean
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
//jsp页面的视图解析器，解析到webapp下的jsp/目录下查找对应的jsp页面
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/jsp");
resolver.setSuffix(".jsp");
resolver.setViewNames("*");//这里是设置该视图解析器所要匹配哪些格式的视图“*”代表匹配所有格式“
resolver.setOrder(2);//优先级,Spring配置多个视图解析器，数字越小，优先级越高，越先匹配
return resolver;
}
/**
* 下面都是配置hymeleaf的视图解析器相关的内容
* 对thymeleaf的视图解析器，解析到webapp下的html目录下查找对应的页面
* @return
*/
@Bean
public ITemplateResolver templateResolver() {
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setTemplateMode("HTML5");
templateResolver.setPrefix("WEB-INF/");
templateResolver.setSuffix(".html");
templateResolver.setCharacterEncoding("utf-8");
templateResolver.setCacheable(false);
return templateResolver;
}
@Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
// templateEngine
return templateEngine;
}
@Bean
public ThymeleafViewResolver viewResolverThymeLeaf() {
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
viewResolver.setCharacterEncoding("utf-8");
viewResolver.setOrder(1);//设置该视图解析器优先级为1
//下面是设置该视图解析器所要匹配哪些格式的视图"html/*", "vue/*","jsps/*","templates/*"代表匹配"html/*", "vue/*","jsps/*","templates/*"格式的所有视图
viewResolver.setViewNames(new String[]{"html/*", "vue/*","jsps/*","templates/*"});
return viewResolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
/**
* 配置资源路径
* @param registry
*/
// @Override
// public void addResourceHandlers(ResourceHandlerRegistry registry) {
// registry.addResourceHandler("/img/**").addResourceLocations("/img/");
// registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/" + "/static/");
// }
}
}
第三步：创建webapp
在resource同目录下创建一个webapp的文件夹
上面的直接删除
下面的先减号在加号 指定的文件夹就是你刚刚创建的文件夹
第四步：建文件夹编写代码
第五步：编写控制类
测试
