    SpringBoot是Spring一些列框架的整合,提供“约定大约配置”,把开发者从复杂的配置中解放出来,同时也为微服务提供了借鉴。SpringBoot的发展很快,现在很多公司都采用了此框架。

    环境/版本一览:

    • 开发工具:Intellij IDEA 2017.1.5
    • springboot: 2.0.3.RELEASE
    • jdk:1.8.0_101
    • maven:3.3.9
    • alibaba Druid 数据库连接池:1.1.9

    额外功能:

    • PageHelper 分页插件
    • mybatis generator 自动生成代码插件

    开始搭建:

    创建项目:

    选择Spring Initializr 填写参数

    添加基础的依赖:

    选择模块

    依赖文件:

    按照pom文件补齐需要的依赖:

    项目结构:

    项目启动类:

    启动类修改

    配置:

    根据习惯选择properties或者yml配置文件,本项目采用yml配置文件,把application.properties删除,创建一个application.yml文件

    在resource文件夹下创建application.yml,并做如下配置

    server:
      port: 8080
    
    spring:
        datasource:
            name: test
            url: jdbc:mysql://192.168.0.1/mytest
            username: root
            password: root
            # 使用druid数据源
            type: com.alibaba.druid.pool.DruidDataSource
            driver-class-name: com.mysql.jdbc.Driver
            filters: stat
            maxActive: 20
            initialSize: 1
            maxWait: 60000
            minIdle: 1
            timeBetweenEvictionRunsMillis: 60000
            minEvictableIdleTimeMillis: 300000
            validationQuery: select 'x'
            testWhileIdle: true
            testOnBorrow: false
            testOnReturn: false
            poolPreparedStatements: true
            maxOpenPreparedStatements: 20
    mybatis:
      mapper-locations: classpath:mapping/*.xml
      type-aliases-package: com.lx.model
    
    #pagehelper分页插件
    pagehelper:
        helperDialect: mysql
        reasonable: true
        supportMethodsArguments: true
        params: count=countSql
    
    

    使用mybatis generator生成model、mapper、DAO文件

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration
            PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
            "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
    <generatorConfiguration>
        <!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包-->
        <classPathEntry  location="\apache-maven-3.3.9\repository\mysql\mysql-connector-java\5.1.46\mysql-connector-java-5.1.46.jar"/>
        <context id="DB2Tables"  targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                <!-- 是否去除自动生成的注释 true:是 : false:否 -->
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
            <!--数据库链接URL,用户名、密码 -->
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.0.1/mytest" userId="root" password="root">
            </jdbcConnection>
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
            <!-- 生成模型的包名和位置-->
            <javaModelGenerator targetPackage="com.lx.model" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
                <property name="trimStrings" value="true"/>
            </javaModelGenerator>
            <!-- 生成映射文件的包名和位置-->
            <sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources">
                <property name="enableSubPackages" value="true"/>
            </sqlMapGenerator>
            <!-- 生成DAO的包名和位置-->
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.lx.mapper" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
            <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
            <table tableName="t_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        </context>
    </generatorConfiguration>
