spring中使用mybatis plus连接sqlserver的方法实现

本文主要关注如何使用mybatis/mybatis plus连接SQL Server数据库，因此将省略其他项目配置、代码。

应用框架：spring bootORM框架：mybatis plus（对于连接数据库而言，mybatis和mybatis plus其实都一样）数据库连接池：druid

此处仅给出我的配置，mybatis/druid请依据自己项目的需要进行选择。方便起见我用的是mybatis plus

<!--mybatis plus --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.1.0</version> </dependency><dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.7</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.0</version> </dependency> <!-- druid 连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.12</version> </dependency> <!--for SqlServer--> <dependency> <groupId>com.microsoft.sqlserver</groupId> <artifactId>sqljdbc4</artifactId> <version>4.0</version> </dependency>配置数据源

添加数据库配置

YAML文件中添加自己数据库的地址

# SQL Server数据库spring.datasource.xx.url: jdbc:sqlserver://你的数据库地址:1433;databaseName=你的数据库名称spring.datasource.xx.username: xxxxspring.datasource.xx.password: xxxxspring.datasource.xx.driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver添加数据源

此处和平时我们在spring boot中集成mybatis/mybatis plus一样，添加bean即可。由于平时经常用到多个数据库，此处展示一个多数据源的例子：一个是mysql，一个是SQL Server有关mybatis plus配置数据源的注意事项，比如配置mapper文件夹等，请自行问度娘，此处不再一一指出。注意：下面代码来自实际代码，但批量删除了敏感信息、重新命名，因而可能存在与前面配置信息不一致的地方，仅仅是一个示例

mysql数据源配置，注意，由于是多数据源，需要有一个数据源配置中加上@Primary注解

@Configuration@MapperScan(basePackages = 'com.xxx.mapper', sqlSessionFactoryRef = 'mysqlSqlSessionFactory')public class MySQLMybatisPlusConfig { @Autowired private MybatisPlusProperties properties; @Autowired private ResourceLoader resourceLoader = new DefaultResourceLoader(); @Autowired(required = false) private Interceptor[] interceptors; @Autowired(required = false) private DatabaseIdProvider databaseIdProvider; @Autowired private Environment env; @Bean(name = 'mysqlDataSource') @Primary public DataSource getRecruitDataSource() throws Exception { Properties props = new Properties(); props.put('driverClassName', env.getProperty('spring.datasource.mysqlData.driver-class-name')); props.put('url', env.getProperty('spring.datasource.mysqlData.url')); props.put('username', env.getProperty('spring.datasource.mysqlData.username')); props.put('password', env.getProperty('spring.datasource.mysqlData.password')); return DruidDataSourceFactory.createDataSource(props); } /** * mybatis-plus分页插件 */ @Bean public PaginationInterceptor paginationInterceptor() { PaginationInterceptor page = new PaginationInterceptor(); page.setDialectType('mysql'); return page; } @Bean(name = 'mysqlSqlSessionFactory') @Primary public MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean(@Qualifier('mysqlDataSource') DataSource mysqlDataSource) throws IOException { MybatisSqlSessionFactoryBean mybatisPlus = new MybatisSqlSessionFactoryBean(); try { mybatisPlus.setDataSource(mysqlDataSource); } catch (Exception e) { e.printStackTrace(); } mybatisPlus.setVfs(SpringBootVFS.class); // 设置分页插件 MybatisConfiguration mc = new MybatisConfiguration(); mc.setDefaultScriptingLanguage(MybatisXMLLanguageDriver.class); mc.setMapUnderscoreToCamelCase(true);// 数据库和java都是驼峰，就不需要 mybatisPlus.setConfiguration(mc); if (this.databaseIdProvider != null) { mybatisPlus.setDatabaseIdProvider(this.databaseIdProvider); } mybatisPlus.setTypeAliasesPackage('com.xxx.mysql.bean.model'); mybatisPlus.setTypeHandlersPackage(this.properties.getTypeHandlersPackage()); mybatisPlus.setMapperLocations(this.properties.resolveMapperLocations()); // 设置mapper.xml文件的路径 ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); Resource[] resource = resolver.getResources('classpath:mapper/*.xml'); mybatisPlus.setMapperLocations(resource); return mybatisPlus; }}

SQL Server数据源

@Configuration@MapperScan(basePackages = 'com.xxx.survey.mapper', sqlSessionFactoryRef = 'xxSqlSessionFactory')public class SqlServerMybatisConfig { @Autowired private MybatisPlusProperties properties; @Autowired private ResourceLoader resourceLoader = new DefaultResourceLoader(); @Autowired(required = false) private Interceptor[] interceptors; @Autowired(required = false) private DatabaseIdProvider databaseIdProvider; @Autowired private Environment env; @Bean(name = 'xxDataSource') public DataSource getAttendanceDataSource() throws Exception { Properties props = new Properties(); props.put('driverClassName', env.getProperty('spring.datasource.xx.driver-class-name')); props.put('url', env.getProperty('spring.datasource.xx.url')); props.put('username', env.getProperty('spring.datasource.xx.username')); props.put('password', env.getProperty('spring.datasource.xx.password')); return DruidDataSourceFactory.createDataSource(props); } @Bean(name = 'xxSqlSessionFactory') public MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean(@Qualifier('xxDataSource') DataSource xxDataSource) throws IOException { MybatisSqlSessionFactoryBean mybatisPlus = new MybatisSqlSessionFactoryBean(); try { mybatisPlus.setDataSource(xxDataSource); } catch (Exception e) { e.printStackTrace(); } mybatisPlus.setVfs(SpringBootVFS.class); // 设置分页插件 MybatisConfiguration mc = new MybatisConfiguration(); mc.setDefaultScriptingLanguage(MybatisXMLLanguageDriver.class); mc.setMapUnderscoreToCamelCase(true);// 数据库和java都是驼峰，就不需要 mybatisPlus.setConfiguration(mc); if (this.databaseIdProvider != null) { mybatisPlus.setDatabaseIdProvider(this.databaseIdProvider); } mybatisPlus.setTypeAliasesPackage('com.xxx.survey.bean.model'); mybatisPlus.setTypeHandlersPackage(this.properties.getTypeHandlersPackage()); mybatisPlus.setMapperLocations(this.properties.resolveMapperLocations()); // 设置mapper.xml文件的路径 ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); Resource[] resource = resolver.getResources('classpath:mapper/*.xml'); mybatisPlus.setMapperLocations(resource); return mybatisPlus; }}生成ORM代码

到这里，程序启动应该没什么问题，接着就应该生成DAO层、Service层代码了mybatis和mybatis plus在此处按照和连接mysql时一样的方法，根据需要写代码即可。比如对于mybatis plus，需要写3处代码：

实体bean，可以利用Spring Boot Code Generator!来根据SQL表结构自动生成

Mapper代码：都有模板，mybatis plus自己封装的方法已经很够用，有单独需求可以自己写xml来自定义SQL

@Mapperpublic interface XXXMapper extends BaseMapper<XXX> {}

Service代码好像也有现成的工具可以自动生成mapper service代码来着。Service接口

public interface XXXService extends IService<XXX> {}

ServiceImpl

@Servicepublic class XXXServiceImpl extends ServiceImpl<XXXMapper, XXX> implements XXXService {}参考资料
