(四)Spring Boot 整合 jsp

项目目录

一、创建项目

(1)连个都勾选

(2)项目打包成web,因为要应用jsp

(3) 项目报错,修正:原因,因为创建了web工程,缺少文件。手动添加,如图:

二、添加项目依赖 pom.xml

  <parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.3.3.RELEASE</version>
	</parent>
	<dependencies>
		<!-- SpringBoot 核心组件 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<!-- 部署tomcat,排除冲突-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-tomcat</artifactId>
		</dependency>
		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-jasper</artifactId>
		</dependency>
		<!-- servlet依赖 -->
        <dependency>
              <groupId>javax.servlet</groupId>
              <artifactId>javax.servlet-api</artifactId> 
        </dependency>
        <dependency>
              <groupId>javax.servlet</groupId>
              <artifactId>jstl</artifactId>
        </dependency>
	</dependencies>

三’、添加application.properties配置文件

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

四、创建controller类

@Controller
public class HelloController {
	@RequestMapping("/hello")
	public String index(Model m) {
		 m.addAttribute("now",DateFormat.getDateTimeInstance().format(new Date()));//将数据存放到model中
		return "hello";//视图重定向hello.jsp
	}
}

关键代码说明:

@Controller:指定只是一个controller类,请求前端连接处理的类标识。

五、创建启动类

package com.springboot.application;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;



//@ComponentScan("com.springboot.controller")
//@EnableAutoConfiguration
@SpringBootApplication(scanBasePackages = "com.springboot")
public class Application {
	public static void main(String[] args) {

		SpringApplication.run(Application.class, args);

	}
}

关键代码说明:

@SpringBootApplication(scanBasePackages = "com.springboot")

springboot项目启动类,@SpringBootApplication是一个复合注解,包括@ComponentScan,和@SpringBootConfiguration@EnableAutoConfiguration

六、启动测试
