一、引入依賴
<!-- Spring-Mybatis -->
<dependency>
? ? ?<groupId>org.mybatis.spring.boot</groupId>
? ? ?<artifactId>mybatis-spring-boot-starter</artifactId>
????<version>1.3.0</version>
?</dependency>
<!-- MySQL -->
<dependency>
????<groupId>mysql</groupId>
????<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
? ? ? ? <groupId>org.springframework.boot</groupId>
? ? ? ? <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- data source -->
<dependency>
? ? <groupId>com.alibaba</groupId>
? ? <artifactId>druid</artifactId>
? ? <version>1.1.6</version>
</dependency>
二、配置application.properties?
## 數據庫配置
## 數據源
spring.datasource.type = com.alibaba.druid.pool.DruidDataSource
## 數據庫連接
spring.datasource.url=jdbc:mysql://localhost:3306/testdb?useUnicode=true&characterEncoding=utf8
## 數據庫用戶名
spring.datasource.username=root
## 數據庫連接密碼
spring.datasource.password=123456
## 數據庫連接驅動
spring.datasource.driverClassName=com.mysql.jdbc.Driver
## 配置監控統計攔截filters
spring.datasource.filters = stat
## 連接池最大使用連接數
spring.datasource.maxActive = 20
## 初始化連接大小
spring.datasource.initialSize = 3
## 獲取連接最大等待時間
spring.datasource.maxWait = 60000
## 連接池最小空閑
spring.datasource.minIdle = 1
## 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis = 60000
## 配置一個連接在池中最小生存的時間，單位是毫秒
spring.datasource.minEvictableIdleTimeMillis = 300000
spring.datasource.validationQuery = select 'x'
spring.datasource.testWhileIdle = true
spring.datasource.testOnBorrow = false
spring.datasource.testOnReturn = false
spring.datasource.poolPreparedStatements = true
spring.datasource.maxOpenPreparedStatements = 20
三、配置DruidConfig
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import java.sql.SQLException;
/**

@Configuration
public class DruidConfig {
? ? @Value("${spring.datasource.url}")
? ? private String dbUrl;
? ? @Value("${spring.datasource.username}")
? ? private String username;
? ? @Value("${spring.datasource.password}")
? ? private String password;
? ? @Value("${spring.datasource.driverClassName}")
? ? private String driverClassName;
? ? @Value("${spring.datasource.initialSize}")
? ? private int initialSize;

? ? private boolean testOnReturn;
? ? @Value("${spring.datasource.poolPreparedStatements}")
? ? private boolean poolPreparedStatements;
? ? @Value("${spring.datasource.filters}")
? ? private String filters;
? ? @Bean
? ? public ServletRegistrationBean druidServlet() {
? ? ? ? ServletRegistrationBean reg = new ServletRegistrationBean();
? ? ? ? reg.setServlet(new StatViewServlet());
? ? ? ? reg.addUrlMappings("/druid/*");
? ? ? ? reg.addInitParameter("loginUsername", "admin");
? ? ? ? reg.addInitParameter("loginPassword", "123456");
? ? ? ? return reg;
? ? }
? ? @Bean
? ? public FilterRegistrationBean filterRegistrationBean() {
? ? ? ? FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
? ? ? ? filterRegistrationBean.setFilter(new WebStatFilter());
? ? ? ? filterRegistrationBean.addUrlPatterns("/*");
? ? ? ? filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
? ? ? ? filterRegistrationBean.addInitParameter("profileEnable", "true");
? ? ? ? filterRegistrationBean.addInitParameter("principalCookieName", "USER_COOKIE");
? ? ? ? filterRegistrationBean.addInitParameter("principalSessionName", "USER_SESSION");
? ? ? ? return filterRegistrationBean;
? ? }
? ? @Bean
? ? @Primary
? ? public DruidDataSource druidDataSource() {
? ? ? ? DruidDataSource datasource = new DruidDataSource();
? ? ? ? datasource.setUrl(this.dbUrl);
? ? ? ? datasource.setUsername(username);
? ? ? ? datasource.setPassword(password);
? ? ? ? datasource.setDriverClassName(driverClassName);
? ? ? ? datasource.setInitialSize(initialSize);
? ? ? ? datasource.setMinIdle(minIdle);
? ? ? ? datasource.setMaxActive(maxActive);
? ? ? ? datasource.setMaxWait(maxWait);
? ? ? ? datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
? ? ? ? datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
? ? ? ? datasource.setValidationQuery(validationQuery);
? ? ? ? datasource.setTestWhileIdle(testWhileIdle);
? ? ? ? datasource.setTestOnBorrow(testOnBorrow);
? ? ? ? datasource.setTestOnReturn(testOnReturn);
? ? ? ? datasource.setPoolPreparedStatements(poolPreparedStatements);
? ? ? ? try {
? ? ? ? ? ? datasource.setFilters(filters);
? ? ? ? } catch (SQLException e) {
? ? ? ? }
? ? ? ? return datasource;
? ? }
}
四、配置SessionFactory
import javax.sql.DataSource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
/**
* Created by panxiang on 2017-06-25.
*/
@Configuration
@EnableTransactionManagement
@MapperScan(basePackages = SessionFactoryConfig.PACKAGE)
public class SessionFactoryConfig implements TransactionManagementConfigurer {
? ? /**
? ? * mybatis 配置路徑
? ? */
//? static final String MYBATIS_CONFIG = "mybatis-config.xml";
? ? static final String PACKAGE = "com.tool.springBoot.dao";
? ? static final String MAPPER_LOCATION = "classpath:mapper/*.xml";
? ? static final String TYPEALIAS_PACKAGE = "com.tool.springBoot.vo";
? ? @Autowired
? ? private DataSource dataSource;
? ? /**
? ? * 創建sqlSessionFactoryBean 實例
? ? * 并且設置configtion 如駝峰命名.等等
? ? * 設置mapper 映射路徑
? ? * 設置datasource數據源
? ? *
? ? * @return
? ? * @throws Exception
? ? */
? ? @Bean(name = "sqlSessionFactory")
? ? public SqlSessionFactoryBean createSqlSessionFactoryBean() throws Exception {
? ? ? ? SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
? ? ? ? /** 設置mybatis configuration 掃描路徑 */
//? ? ? ? sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(MYBATIS_CONFIG));
? ? ? ? /** 設置datasource */
? ? ? ? sqlSessionFactoryBean.setDataSource(dataSource);
? ? ? ? /** 設置typeAlias 包掃描路徑 */
? ? ? ? sqlSessionFactoryBean.setTypeAliasesPackage(TYPEALIAS_PACKAGE);
? ? ? ? /**設置map映射文件路徑*/
? ? ? ? sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver()
? ? ? ? ? ? ? ? .getResources(SessionFactoryConfig.MAPPER_LOCATION));
? ? ? ? return sqlSessionFactoryBean;
? ? }
? ? @Bean
? ? public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
? ? ? ? return new SqlSessionTemplate(sqlSessionFactory);
? ? }
? ? @Bean
? ? @Override
? ? public PlatformTransactionManager annotationDrivenTransactionManager() {
? ? ? ? return new DataSourceTransactionManager(dataSource);
? ? }
}
五、配置 mapper 的xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.tool.springBoot.dao.TestDao">
? ? <select id="findAll" resultType = "com.tool.springBoot.vo.StudentVO">
? ? ? ? select * from student;
? ? </select>
</mapper>
六、controller
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.tool.springBoot.service.TestService;
@Controller
public class TestController {
@Autowired
private TestService? testService;
@RequestMapping("/hello")
? ? public String index() {
????????testService.testMybatis();
????????return "hello";
? ? }
}
七、service
import com.tool.springBoot.vo.User;
public interface TestService {
????????public String testMybatis();
}
@Component
public class TestServiceImpl implements TestService{
????????@Autowired
????????private TestDao? testDao;
????@Override
????public void testMybatis() {
????????testDao.findAll();
????}
}
八、dao
import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import com.tool.springBoot.vo.StudentVO;
@Mapper
public interface TestDao {
????????public List<StudentVO> findAll();
}
