因为实习用的是MyBatis框架，所以写一篇关于SpringBoot整合MyBatis框架的总结。
一,Pom文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="" xmlns:xsi="" xsi:schemaLocation=" http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>example</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> //这里设置为jar,因为我们会使用jar包部署运行 <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.2.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> //Mybatis的jar包 <version>1.1.1</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> //json数据格式和对象的转换jar包 <version>1.9.8</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>com.h2database</groupId> //内嵌数据库 <artifactId>h2</artifactId> <version>1.3.156</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> //lombok插件,方便model对象的处理 <version>1.16.2</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> //mysql驱动 <version>5.1.18</version> </dependency> </dependencies> <build> <finalName>example</finalName> //打包后的jar包名称 <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> //必须要的SpringBoot继承的maven插件，缺少了无法打包jar。 <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <plugin> <artifactId>maven-resources-plugin</artifactId> //因为jar包中可能存在很多其他的配置资源,例如mapper文件所以打包为jar包需要将其加入，所以需要此资源打包插件 <version>2.5</version> <executions> <execution> <id>copy-xmls</id> <phase>process-sources</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <outputDirectory>${basedir}/target/classes</outputDirectory> <resources> <resource> <directory>${basedir}/src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </configuration> </execution> </executions> </plugin> </plugins> <resources> //打包包含相应的资源文件 <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.tld</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.tld</include> </includes> <filtering>false</filtering> </resource> </resources> </build> <repositories>//设置仓库 <repository> <id>spring-milestone</id> <url></url> </repository> </repositories> </project>
好了简单的SpringBoot整合Mybatis框架的基础环境已经搭建完成了，一个Pom文件搞定，接下来我们配置我们的配置文件。
二,配置文件
我们写在resources目录下的application.properties文件中。
spring.datasource.url=jdbc:mysql://localhost:3306/数据库名称?useUnicode=true&characterEncoding=UTF8 spring.datasource.username=用户名 spring.datasource.password=用户密码 spring.datasource.driver-class-name=com.mysql.jdbc.Driver mybatis.mapper-locations=classpath*:/mapper/*Mapper.xml //mapper文件的路径 mybatis.type-aliases-package=map.model //mapper文件中的前缀 server.port=监听端口号,不设置默认8080
ok，现在环境已经彻底搭建完成我们可以编写自己的代码了。
三，编写代码
Model对象
@Data//@Data lombok插件的注解自动添加get set方法 public class ExampleModel { private Long id; private String name; } //一个简单的model对象
Dao层
