快速开始一个springboot项目

Spring Boot

• 快速第一个Spring Boot应用(2.1.3.RELEASE)

  • idea创建
  • 从官网下载

• 通过配置，快速整合spring mvc、mybatis 、 thymleaf 示例

  • spring mvc 支持

            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    

  • thymleaf 整合 模板引擎

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
    

    spring:
      thymeleaf:
        cache: false # 关闭缓存
        prefix: classpath:/pages/  #修改默认路径
    

    eg:
    spring:
    	thymeleaf:
    		cache: false #默认关闭前端缓存
    		prefix: classpath:/templates/ #前缀
    		suffix: .html #后缀
    

  • mybatis 整合

      	<dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>2.1.1</version>
          </dependency>
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <scope>runtime</scope>
          </dependency>
    

    spring:
      datasource:
        url: jdbc:mysql://localhost:3306/qcby_0319?useUnicode=true&characterEncoding=utf-8&serverTimezone=CTT
        username: root
        password:
      driver-class-name: com.mysql.cj.jdbc.Driver
        
    mybatis:
      mapper-locations: classpath:mapper/*.xml  #对应mapper映射xml文件所在路径
      type-aliases-package: com.xxxx.entity  #对应实体类路径
    

  启动类上加上mapper包注解
    @MapperScan("com.xxxx.mapper")
    @SpringBootApplication
  

  • pageHelper 分页插件整合，需要注意和mybatis-spring-boot-starter的版本关系

            <!--pageHelper分页插件-->
            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper-spring-boot-starter</artifactId>
                <version>1.3.0</version>
            </dependency>
    

    pagehelper:
      helperDialect: mysql
      reasonable: true
      supportMethodsArguments: true
      params: count=countSql
    

            Page<Object> page = PageHelper.startPage(logInfoVo.getPage(), logInfoVo.getLimit());
            List<LogInfo> data = logInfoMappper.queryAllLogInfoForList(logInfoVo);
    

  • HuTool 验证码依赖引入

    • 使用HuTool工具类，实现登录验证码：https://www.e-learn.cn/topic/3515429

    
            <dependency>
                <groupId>cn.hutool</groupId>
                <artifactId>hutool-all</artifactId>
                <version>5.2.3</version>
            </dependency>
    

  • 文件上传引用的一个依赖

           <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjweaver</artifactId>
                <version>1.6.8</version>
            </dependency>
