添加数据源配置：

1.首页创建一个maven中工程，引入 demo_db.sql

前端配置

angular版本

主要是环境变量的配置，数据权限管理、数据字典管理、所有dao继承BaseDao * <p> * Modify histoty: * * @author cjh * @version 1.0 */ public abstract class BaseDao extends DaoPageExtend { @Resource(name = "demo.sqlSessionTemplate") public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) { this.sqlSessionTemplate = sqlSessionTemplate; } public SqlSessionTemplate getSqlSessionTemplate() { return sqlSessionTemplate; } }

dao impl使用时需要继承baseDao就可以使用sqlSessionTemplate和分页实现了

package com.cjhme.demo.impl.dao.student.impl; import java.util.Map; import org.springframework.stereotype.Repository; import com.cjhme.common.model.base.DataPaging; import com.cjhme.demo.common.model.DemoBean; import com.cjhme.demo.impl.base.dao.BaseDao; import com.cjhme.demo.impl.dao.student.StudentDao; @Repository("demo.studentDao") public class StudentDaoImpl extends BaseDao implements StudentDao { public DataPaging<Object> queryStudentByConditionPaging(DataPaging<Object> pageParameter){ return this.selectPaging("com.cjhme.demo.impl.dao.student.StudentDao.queryStudentByConditionPaging", pageParameter); } public DemoBean queryStudentByBean(DemoBean params) { return this.sqlSessionTemplate.selectOne("com.cjhme.demo.impl.dao.student.StudentDao.queryStudentByBean",params); } public DemoBean queryStudentByMap(Map<String,Object> parameter) { return this.sqlSessionTemplate.selectOne("com.cjhme.demo.impl.dao.student.StudentDao.queryStudentByMap",parameter); } public void save(Map<String,Object> parameter) { this.sqlSessionTemplate.insert("com.cjhme.demo.impl.dao.student.StudentDao.save",parameter); } } 

数据权限mybatis插件的使用请参考
com.cjhme.system.impl.base.mybatis.datapermissions包下的已有实现，需要结合数据库的t_data_permissions表配置（这个可以在界面上直接配置）

其它的自己看咯！配置内容放在
application-xxx.properties文件中，注入sqlSessionTemplate

package com.cjhme.demo.impl.base.dao; import javax.annotation.Resource; import org.mybatis.spring.SqlSessionTemplate; import com.cjhme.system.impl.base.mybatis.dao.DaoPageExtend; /** * * <p> * Title: BaseDao.java * </p> * Description: 基础BaseDao，计划开发react版本
技术
前端技术
angular版本
angular11+ng-zorro-antd11+less
vue版本
vue3.0+ant-design-vue2+less

后端技术
spring boot+mybatis3.1.1 + maven+mysql8.0

目录结构
前端
angular版本
angular版本将功能的代码分为平台和业务两个部分，参考demo，将上面创建的datasource注入就可以了使用就可以了
package com.cjhme.demo.impl.base.config; import java.util.Properties; import javax.annotation.Resource; import javax.sql.DataSource; import org.apache.ibatis.plugin.Interceptor; import org.mybatis.spring.SqlSessionFactoryBean; import org.mybatis.spring.SqlSessionTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.env.Environment; import org.springframework.core.io.ClassPathResource; import org.springframework.core.io.support.PathMatchingResourcePatternResolver; import org.springframework.core.io.support.ResourcePatternResolver; import com.cjhme.system.impl.base.mybatis.interceptor.PrepareInterceptor; /** * * <p> * Title: MyBatisConfig.java * </p> * Description: mybatis配置 * <p> * Modify histoty: * * @author cjh * @version 1.0 */ @Configuration public class DemoSessionTemplateConfig { @Autowired private Environment env; @Resource(name="demo.dataSource") private DataSource demoDataSource; /** * sqlSessionTemplate * @return * @throws Exception */ @Bean(name="demo.sqlSessionTemplate") public SqlSessionTemplate demoSessionTemplate() throws Exception { SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(env.getProperty("demo.mybatis.configLocation"))); PathMatchingResourcePatternResolver pathMatchingResourcePatternResolver = new PathMatchingResourcePatternResolver(); String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + env.getProperty("demo.mybatis.mapperLocations"); sqlSessionFactoryBean.setMapperLocations(pathMatchingResourcePatternResolver.getResources(packageSearchPath)); sqlSessionFactoryBean.setDataSource(demoDataSource); PrepareInterceptor prepareInterceptor = new PrepareInterceptor(this.env); Properties properties=new Properties(); properties.setProperty("dialect",env.getProperty("demo.dialect")); properties.setProperty("stmtIdRegex",env.getProperty("demo.stmtIdRegex")); prepareInterceptor.setProperties(properties); sqlSessionFactoryBean.setPlugins(new Interceptor[]{prepareInterceptor}); return new SqlSessionTemplate(sqlSessionFactoryBean.getObject()); } } 
dao中创建BaseDao继承DaoPageExtend（分页实现），
