十、Springboot之thymeleaf与jsp共存

：

pom.xml添加依赖

<!--thymeleaf整合JSP需要用到下面的依赖-->

        <dependency>

            <groupId>org.thymeleaf</groupId>

            <artifactId>thymeleaf</artifactId>

        </dependency>

此时项目结构如下：

ViewResolverConfiguration类代码：

package com.luzhanshi.springBootFrame.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

        @Bean

            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;

        }

        /**

            templateResolver.setSuffix(".html");

            templateResolver.setCharacterEncoding("utf-8");

            templateResolver.setCacheable(false);

            return templateResolver;

        }

        @Bean

        public SpringTemplateEngine templateEngine() {

            SpringTemplateEngine templateEngine = new SpringTemplateEngine();

        }

        @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

//        @Override

//        public void addResourceHandlers(ResourceHandlerRegistry registry) {

//            registry.addResourceHandler("/img/**").addResourceLocations("/img/");

//            registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/" + "/static/");

//        }

    }

}

properties文件thyemleaf配置的内容变化为：

# 模版存放路径

#spring.thymeleaf.prefix=classpath:/templates/

spring.thymeleaf.prefix=/WEB-INF/html

html文件以及jsp文件的视图路径为：
