1：springboot使用視圖解析器，添加依賴

<!-- freemarker模板引擎視圖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-freemarker</artifactId></dependency><!-- 熱部署，不用重啟 ，這個(gè)在這里不需要--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional></dependency><!-- jsp解析器 --><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId><scope>provided</scope></dependency>

2：主函數(shù)需要繼承SpringBootServletInitializer，并覆蓋其方法。

package com.liyafei;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer;@EnableAutoConfiguration @SpringBootApplication //返回jsp頁(yè)面必須繼承SpringBootServletInitializer類重寫里面的方法 public class Main extends SpringBootServletInitializer{public static void main(String[] args) {SpringApplication.run(Main.class, args);}protected SpringApplicationBuilder config(SpringApplicationBuilder applicationBuilder){return applicationBuilder.sources(Main.class);} }

3：配置文件中添加spring.mvc.view配置，配置了視圖解析器之后，controlller返回的String，View等就會(huì)先找視圖解析器

spring:datasource:driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://localhost:3306/demousername: rootpassword: 1367356mvc:view:prefix: /WEB-INF/suffix: .jspmybatis:config-location: classpath:mybatis-config.xml

4：controller映射

package com.liyafei.controller;import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.view.json.MappingJackson2JsonView;import com.liyafei.pojo.User;//這個(gè)注解不能使用RestController，不然會(huì)返回模板類型的頁(yè)面 @Controller public class MyController {User user=new User();@RequestMapping("/my")public ModelAndView test(){ModelAndView mv=new ModelAndView();mv.setViewName("modelandview");mv.addObject("name", "liyafei");user.setAge(20);user.setName("wangwu");mv.addObject("user", user);//設(shè)置返回的數(shù)據(jù)為json類型，也可以不設(shè)置，返回對(duì)象//mv.setView(new MappingJackson2JsonView());return mv;}@RequestMapping("index")public String index(){return "index";}}
