Question

我正在src / main内手动创建webapp / WEB-INF / views文件夹，并且还添加了2个依赖项，例如org.apache.tomcat.embed和javax.servlet，但是当我运行时仍然会抛出404正在调用控制器的URL

控制器。

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HolidayController {

    @GetMapping("/test11")
    public String getData()
    {

        System.out.println("in the test contoller");
        return "demoJsp";
    }
}

Spring Boot配置文件。

package com.chml.Chml_Admin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EntityScan("com.chml")
@EnableJpaRepositories("com.chml")
@ComponentScan("com.chml")
public class ChmlAdminApplication {

    public static void main(String[] args) {
        SpringApplication.run(ChmlAdminApplication.class, args);
    }

}

application.properties。

#==== connect to mysql ======# 

spring.jpa.hibernate.ddl-auto=update 
spring.datasource.url=jdbc:mysql://localhost:3306/chml_admin 
spring.datasource.username=root spring.datasource.password= 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect 

#==== Internal View Resolver ======# 

spring.mvc.view.prefix=/WEB-INF/jsps/ 
spring.mvc.view.suffix=.jsp

JSP。

        </dependency>

我在这里添加了我的项目结构

我尝试了各种方法，但是没有得到任何解决方案，请告诉我在任何地方是否出错。

Answer 1

根据屏幕截图，您需要在 application.properties中将视图前缀从views更改为jsps。

spring.mvc.view.prefix=/WEB-INF/jsps/ 
spring.mvc.view.suffix=.jsp

无法呈现JSP页面
