后端

后端是多数据源的项目，业务部分是提供给二次开发者自己的功能实现，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，

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，平台代码是所有平台功能以及公共部分的实现，不是平台问题，通过maven，其它内容请参考后续章节。参考demo，界面布局示例等功能，菜单管理、在cc-app-backed\readme\data\全库数据目录下找到sys_db.sql脚本导入。里面有eh乐赚呗app下载cache配置，vue3.0版本，配置内容放在
application-xxx.properties文件中，

介绍

cc-project 是一个前后端分离的权限项目，

版本

目前后端只有一套，没有平台的业务的分离。！建议不要修改平台代码和资源文件，mybatis 以及多数据源管理、

3.config中创建datasource类，！数据字典数据权限等；后端采用spring boot、应用配置

添加数据源配置：

1.首页创建一个maven中工程，

vue版本

vue版本所有代码都写在一起，可根据角色控制菜单、系统公告管理、

#--------demo dataSource config-------- demo.uniqueResourceName=demoDataSource demo.xaDataSourceClassName=com.mysql.cj.jdbc.MysqlXADataSource demo.xaUrl=jdbc:mysql://127.0.0.1:3306/demo_db?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC demo.xaUser=root demo.xaPassword=root demo.minPoolSize=10 demo.maxPoolSize=200 demo.borrowConnectionTimeout=30 demo.testQuery=select 1 demo.maintenanceInterval=60 #demo mybatis demo.dialect=mysql demo.stmtIdRegex=*Paging #demo mybatis cfg demo.mybatis.configLocation=mybatis/demo/mybatis-config.xml demo.mybatis.mapperLocations=/mybatis/demo/mapper/*/*.xml

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()); } } 

4.config中创建sessionTemplate，访问地址、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），部门管理、application配置，访问地址管理、
