4-springboot集成mybatis

1.pom.xml中添加mybatis依赖

2.application.properties中添加数据源配置

3.反向生成dao的代码

1.

<!-- mybatis-spring-boot-starter -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.1</version>
</dependency>

<!-- MySQL的jdbc驱动包 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

添加xml和properties的编译配置

<resource>
    <directory>src/main/java</directory>
    <includes>
        <include>**/*.*</include>
    </includes>
</resource>
<resource>
    <directory>src/main/resources</directory>
    <includes>
        <include>**/*.*</include>
    </includes>
</resource>

2.

spring.datasource.url=url
spring.datasource.username=uat
spring.datasource.password=uat
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3.自动生成mapper代码-见文章

pom中添加配置然后添加自定义生成mapper的类:

<!-- mybatis-generator -->
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.7</version>
</dependency>

如果是从其他项目拷贝进来的，注意此处需要更改为正确的项目地址:
