SpringBoot整合Mybatis(SpringBoot项目配置3)

SpringBoot框架能自动进行对项目进行配置，无需spring.xml,springmvc.xml配置文件，但有些配置内容需要还告诉SpringBoot框架，以便让它知道如何去进行自动配置，如数据库的驱动、用户名、密码，连接池等数据。

1.引入jar包（mybatis的jar包，数据库连接池的jar包和mybatis与springBoot整合的jar包）

在pom.xml中加入如下内容

<span>&lt;!--</span><span>整合mybatis</span><span>--&gt;</span> <span>&lt;</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>groupId</span><span>&gt;</span>org.mybatis.spring.boot<span>&lt;/</span><span>groupId</span><span>&gt;</span> <span>&lt;</span><span>artifactId</span><span>&gt;</span>mybatis-spring-boot-starter<span>&lt;/</span><span>artifactId</span><span>&gt;</span> <span>&lt;</span><span>version</span><span>&gt;</span>1.0.0<span>&lt;/</span><span>version</span><span>&gt;</span> <span>&lt;/</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>groupId</span><span>&gt;</span>com.alibaba<span>&lt;/</span><span>groupId</span><span>&gt;</span> <span>&lt;</span><span>artifactId</span><span>&gt;</span>druid<span>&lt;/</span><span>artifactId</span><span>&gt;</span> <span>&lt;</span><span>version</span><span>&gt;</span>1.0.19<span>&lt;/</span><span>version</span><span>&gt;</span> <span>&lt;/</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>groupId</span><span>&gt;</span>mysql<span>&lt;/</span><span>groupId</span><span>&gt;</span> <span>&lt;</span><span>artifactId</span><span>&gt;</span>mysql-connector-java<span>&lt;/</span><span>artifactId</span><span>&gt;</span> <span>&lt;</span><span>version</span><span>&gt;</span>5.1.38<span>&lt;/</span><span>version</span><span>&gt;</span> <span>&lt;/</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>dependency</span><span>&gt;</span> <span>&lt;</span><span>groupId</span><span>&gt;</span>org.mybatis<span>&lt;/</span><span>groupId</span><span>&gt;</span> <span>&lt;</span><span>artifactId</span><span>&gt;</span>mybatis<span>&lt;/</span><span>artifactId</span><span>&gt;</span> <span>&lt;</span><span>version</span><span>&gt;</span>3.2.8<span>&lt;/</span><span>version</span><span>&gt;</span> <span>&lt;/</span><span>dependency</span><span>&gt;</span>

<dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.19</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency>

2.在springBoot的配置文件中配置Druid数据源和mybatis的包扫描

在application.xml文件中加入如下内容：

<span> datasource: url: jdbc:mysql://localhost:3306/test name: test username: root password: hr driver: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource mybatis: mapper-locations: classpath:com/baizhi/mapper/*Mapper.xml type-aliases-package: com.baizhi.entity</span>

1	<span> datasource: url: jdbc:mysql://localhost:3306/test name: test username: root password: hr driver: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource mybatis: mapper-locations: classpath:com/baizhi/mapper/*Mapper.xml type-aliases-package: com.baizhi.entity</span>
