Mybatis和springboot集成

mybaits和springboot集成即可以写在application.yml里配置

mybatis: mapper-locations: classpath:mapping/*Mapper.xml type-aliases-package: com.example.entity

也可以写在java类里

使用@Bean的方式住入sqlSessionFactory

@Bean("sqlSessionFactory")

public SqlSessionFactory sqlSession(@Qualifier("dynamicDataSource")DataSource dynamicDataSource) {

ResourcePatternResolver patternResolver = ResourcePatternUtils.getResourcePatternResolver(new DefaultResourceLoader());

SqlSessionFactoryBean sqlSession = new SqlSessionFactoryBean();

sqlSession.setDataSource(dynamicDataSource);

sqlSession.setVfs(SpringBootVFS.class);

ibatis.session.Configuration conf = new ibatis.session.Configuration();

//查询结果map为空值时不忽略空值

conf.setCallSettersOnNulls(true);

//开启驼峰命名模式

conf.setMapUnerscoreToCamelCase(true);

sqlSession.setConfiguration(conf);

sqlSession.setMapperLocations(patternResolver.getSources(mapperLocation));

}

@Configuration

@MapperScan("")

@AutoConfigureAfter(DataSourceConfiguration.class)

 MapperScannerConfigurer的使用
