1、maven依赖
向pom.xml添加如下依赖
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
| <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>com.github.miemiedev</groupId> <artifactId>mybatis-paginator</artifactId> <version>1.2.15</version> </dependency> <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-juli</artifactId> <version>8.5.23</version> </dependency>
|
2、配置springboot
向application.properties(或者.yml)添加如下配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14
| #mybaits配置 mybatis.config-location=classpath:mybatis.xml #等效于mybaits.xml的别名配置 #mybatis.type-aliases-package=com.example.demo.dao.entity #等效于mybaits.xml的mapper扫描配置 #mybatis.mapper-locations=classpath:com/example/demo/dao/mapper/*.xml #数据源配置,指定为mysql的c3p0数据源 spring.datasource.name=test spring.datasource.url=jdbc:mysql://192.168.100.25:6660/TXSMS?useUnicode=true&characterEncoding=utf-8 spring.datasource.username=root spring.datasource.password=123456 spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.type=com.mchange.v2.c3p0.ComboPooledDataSource
|
3、Dao层
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
| @Repository public class TestUserDao { @Autowired private SqlSessionTemplate sqlSessionTemplate; public TXDBUser getUserById(Integer id) { return sqlSessionTemplate.selectOne("com.wxtx.dao.TestUserDao.selectUserById", id); } public List<TXDBUser> getUserList(TXDBUser user, PageBounds pageBounds) { return sqlSessionTemplate.selectList("com.wxtx.dao.TestUserDao.selectUserList", user, pageBounds); } public List<TXDBUser> getPrinterList() { return sqlSessionTemplate.selectList("com.wxtx.dao.TestUserDao.selectPrinter"); } public void updateUser(TXDBUser user) { sqlSessionTemplate.update("com.wxtx.dao.TestUserDao.updateUser", user); } }
|
注:此处的SqlSessionTemplate为springboot自动注册的bean,不需要开发者自己注册实现。
4、事物管理
通过@Transactional注解添加事务,@Transactional注解默认只在发生RuntimeException and Error两种异常时回滚事物。所以实际开发需要指定为当发生任何异常时均回滚事务。
1 2 3 4 5 6 7 8 9 10 11 12
| @Service @Transactional(rollbackFor=Throwable.class) public class TestService {
@Autowired private TestUserDao userDao; public List<TXDBUser> getUserList(){ return userDao.getUserList(new TXDBUser(),new PageBounds()); } }
|
5、注意事项
所有的xml文件都不能放在src/main/java路径下,否则打包部署的时候会找不到该路径下的所有xml文件。所有非java文件例如mybatis的mapper映射文件均放在src/main/resources路径及子路径下。
