1、配置pom.xml

教程一创建的项目为maven项目,所以搭建一个Spring Boot的Web项目,先导入一下jar包:即在pom.xml以下依赖:

  1 <dependencies>
  2         <dependency>
  3             <groupId>org.springframework.boot</groupId>
  4             <artifactId>spring-boot-starter-web</artifactId>

103         </dependency>
104 
105     </dependencies>

Springboot的默认视图支持是Thymeleaf,但是Thymeleaf我们不熟悉,我们熟悉的还是jsp。 所以下面是讲解如何让Springboot支持 jsp。

修改pom.xml文件,添加对jsp支持

 1 <!-- servlet依赖 -->
 2         <dependency>
 3               <groupId>javax.servlet</groupId>
 4               <artifactId>javax.servlet-api</artifactId>    
 5         </dependency>
 6         <dependency>
 7               <groupId>javax.servlet</groupId>
 8               <artifactId>jstl</artifactId>
 9         </dependency>
10         <!-- tomcat的支持-->
11         <dependency>
12                <groupId>org.apache.tomcat.embed</groupId>
13                <artifactId>tomcat-embed-jasper</artifactId>
14         </dependency>

数据库驱动依赖根据数据库版本修改


 

2、配置webapp

手动在src/main/目录下创建webapp/WEB-INF,然后打开以下界面,设置web目录

 

 结果如下: 

 

接下来配置application.properties,但是application.yml是树状结构,修改查看比较清晰直观,所以推荐使用。

在application.yml添加如下配置:

spring:
  mvc:
    view:
      prefix: /WEB-INF/jsp/
      suffix: .jsp
  datasource:
    url: jdbc:mysql://localhost:3306/?
    username: root
    password: 
    driver-class-name: com.mysql.cj.jdbc.Driver
  jpa:
    show-sql: true
    generate-ddl: true
    hibernate:
      ddl-auto: update
    properties:
        hibernate:
          dialect: org.hibernate.dialect.MySQL55Dialect
    database: MYSQL

 

这样配置了数据库连接和控制web访问路径和格式。


3、配置开发目录和环境配置,在resources文件下创建mapper文件夹,主要放置*mapper.xml,其他的逻辑代码放置在java包下,注意不能放在启动类的外部,应该和启动类同级或启动类所在的包能包含别的代码所在的包,否则会扫描不到代码,启动时或者运行时会报错。

⚠️添加完依赖记得重新导入maven,然后查看是否有依赖冲突,以上项目配置的仅支持jdk1.8版本,别的版本会有不同的错误,但可以解决。
