SpringBoot配置Mybatis的三种方式
仅供参考：
*第一种：新建一个maven工程，配置pom和application.properties文件
*springBootConfig：
springConfig:
springMvc:
pom.xml:`
4.0.0
org.springframework.boot
spring-boot-starter-parent
1.5.2.RELEASE
com.youzhong
ssm-boot
0.0.1-SNAPSHOT
war
org.springframework.boot
spring-boot-devtools
true
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-tomcat
provided
org.apache.tomcat.embed
tomcat-embed-jasper
provided
javax.servlet
jstl
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.3.0
mysql
mysql-connector-java
org.springframework.boot
spring-boot-maven-plugin
`
application.properties文件：
server.port=9090
server.context-path=/
#rizhi
logging.file=D:/mylog/log.log
logging.level.org.springframework.web = DEBUG
##
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
# \u6570\u636E\u6E90\u914D\u7F6E
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
# mybatis \u914D\u7F6E
#mybatis.config-location=classpath:mybatis/mybatis-config.xml
mybatis.mapper-locations=classpath:/mapper/*.xml
第二种：
1 创建maven，搭建springboot环境
2 在pom.xml文件中引入依赖
org.springframework.boot
spring-boot-starter-jdbc
mysql
mysql-connector-java
com.alibaba
druid
1.0.14
org.mybatis
mybatis
3.2.8
org.mybatis
mybatis-spring
1.2.2
3 创建jdbc.properties
##for mysql
jdbc.driver=com.mysql.jdbc.Driver
#jdbc.url=jdbc:mysql://60.220.247.94:3306/czsctest?useUnicode=true&characterEncoding=UTF-8
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=UTF-8
#jdbc.url=jdbc:mysql://60.220.247.94:3306/czsctest
jdbc.username=root
jdbc.password=root
4 创建JdbcConfig.java类，通过@ConfigurationProperties读取jdbc.properties属性信息
//前缀 + 属性名称 === 属性文件的key
@Component
@ConfigurationProperties(prefix="jdbc")
public class JdbcConfig {
private String driver;//jdbc.driver=
private String jdbcUrl;//jdbc.jdbcUrl=
private String username;//jdbc.username
private String password;//jdbc.password
。。。。
}
5 创建datasource 配置类
@Configuration
public class DataSourceConfig {
@Autowired
private JdbcConfig jdbcConfig;
@Bean(“dataSource”)
public DruidDataSource buildDataSource(){
DruidDataSource dataSource = new DruidDataSource();
dataSource.setUrl(jdbcConfig.getJdbcUrl());
dataSource.setUsername(jdbcConfig.getUsername());
dataSource.setDriverClassName(jdbcConfig.getDriver());
dataSource.setPassword(jdbcConfig.getPassword());
return dataSource;
}
}
6 创建mybaits的配置类
@Configuration
@PropertySource(“classpath:jdbc.properties”)
public class MybaitisConfig {
@Autowired
private DataSource dataSource;
//spring与mybaits整合
//1 配置datasoruce
//2 创建meybiats的sqlsessionfacory
//3 扫描mybats的接口mapper接口
@Bean(“sqlSessionFactory”)
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
// 设置数据源
sqlSessionFactoryBean.setDataSource(dataSource);
// 设置mybatis的主配置文件
// sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(“mybatis/mybatis-config.xml”));
ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
Resource[] resources = resolver.getResources("classpath:/mapper/*.xml");
sqlSessionFactoryBean.setMapperLocations(resources);
// 设置别名包
sqlSessionFactoryBean.setTypeAliasesPackage("com.light.springboot.domain");
return sqlSessionFactoryBean.getObject();
}
@Bean
public MapperScannerConfigurer buildMapperScannerConfigurer(){
MapperScannerConfigurer config = new MapperScannerConfigurer();
//设置扫描的mapper的接口包
config.setBasePackage("com.yzit.plateform.dao");
config.setSqlSessionFactoryBeanName("sqlSessionFactory");
return config;
}
}
7 创建数据库以及表
8 mybaits代码生成mapper接口以及mapper.xml
9 创建service、接口以及实现类
10 创建controller
//@RestController == @controller +@responbody
@RestController
public class RoleController {
@Autowired
private RoleService roleService;
@RequestMapping("/role/v_list.do")
public List findAll(){
return roleService.findAll();
}
}
11 创建springmvc的配置
@Configuration
@ComponentScan({“com.yzit.plateform.controller”,“com.yzit.plateform.service”})
@MapperScan(value=“com.yzit.plateform.dao”)
public class SpringConfig {
}
12 创建springboot的启动类
@SpringBootApplication
public class SpringBootConfig {
public static void main(String[] args) {
SpringApplication.run(SpringBootConfig.class, args);
}
}
第三种：
1 创建maven，搭建springboot环境
2 在pom.xml文件中引入依赖
org.springframework.boot spring-boot-starter-aop org.springframework.boot spring-boot-starter-jdbc
mysql
mysql-connector-java
com.alibaba
druid
1.0.14
org.mybatis
mybatis
3.2.8
org.mybatis
mybatis-spring
1.2.2
3 创建jdbc.properties
##for mysql
jdbc.driver=com.mysql.jdbc.Driver
#jdbc.url=jdbc:mysql://60.220.247.94:3306/czsctest?useUnicode=true&characterEncoding=UTF-8
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=UTF-8
#jdbc.url=jdbc:mysql://60.220.247.94:3306/czsctest
jdbc.username=root
jdbc.password=root
4 创建spring-mybagti的配置文件
classpath:jdbc.properties
classpath*:/mapper/*Mapper.xml
5 在springconfig配置类使用importresource注解加载步骤4创建spring-mybaits配置文件
@Configuration
@ComponentScan({“com.yzit.plateform.controller”,“com.yzit.plateform.service”})
@MapperScan(value=“com.yzit.plateform.dao”)
@ImportResource(value = { “classpath:spring-context-mybaits.xml” })
public class SpringConfig {
}
