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

            //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();

        /**

    }

}

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：
