SpringBoot使用ModelAndView時配置視圖解析器

spring boot 使用視圖modelandview

 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：主函數需要繼承SpringBootServletInitializer，並覆蓋其方法。

 

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等就會先找視圖解析器

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/demo
    username: root
    password: 1367356
 mvc: view: prefix: /WEB-INF/ suffix: .jsp mybatis: 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; //這個注解不能使用RestController，不然會返回模板類型的頁面 @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); //設置返回的數據為json類型，也可以不設置，返回對象 //mv.setView(new MappingJackson2JsonView()); return mv; } @RequestMapping("index") public String index(){ return "index"; } 

 

}
