springMVC mybatis 多数据源配置

1.ssm（spring+springMVC+mybatis）环境搭建（略）

2.工程目录及多数据源涉及的文件

1).DataSourceContextHolder.java

package com.zjgt.datasource;import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;public class DataSourceContextHolder {private static final ThreadLocal<String> contextHolder =new ThreadLocal<>();public static void setDbType(String dbType){contextHolder.set(dbType);}public static String getDbType(){return ((String)contextHolder.get());}public static void clearDbType(){contextHolder.remove();}}

2).DynamicDataSource.java

package com.zjgt.datasource;import java.sql.SQLFeatureNotSupportedException;
import java.util.logging.Logger;import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;public class DynamicDataSource extends AbstractRoutingDataSource {@Overrideprotected Object determineCurrentLookupKey() {return DataSourceContextHolder.getDbType();}}

3).jdbc.properties

db1.driverClassName=com.mysql.jdbc.Driver
db1.url=jdbc:mysql://localhost:3306/zjzb_qc?useUnicode=true&amp;characterEncoding=UTF-8
db1.username=root
db1.password=123456db2.driverClassName=com.mysql.jdbc.Driver
db2.url=jdbc:mysql://localhost:3306/zjzb_qc2?useUnicode=true&amp;characterEncoding=UTF-8
db2.username=root
db2.password=123456db3.driverClassName=com.mysql.jdbc.Driver
db3.url=jdbc:mysql://localhost:3306/zjzb_qc3?useUnicode=true&amp;characterEncoding=UTF-8
db3.username=root
db3.password=123456

4).spring-mybatis.xml

3.在web.xml引用spring-mybatis.xml即可

4.在controller里面配置数据源即可（由于service层配置了事务。一旦调用进入到事务内部，再切换数据源则无效。故放在controller里面）

代码示例如下：

@ResponseBody@RequestMapping(value = "_list", produces = "text/html;charset=UTF-8")public String userLists(HttpServletRequest request, HttpServletResponse response) throws JsonProcessingException {//切换数据源到zjzb_qc2DataSourceContextHolder.setDbType("zjzb_qc2");String userName = request.getParameter("userName");String departmentName = request.getParameter("departmentName");String pageSize = request.getParameter("pageSize");String pageCurrent = request.getParameter("pageCurrent");int size = Integer.parseInt(pageSize);int currentPage = Integer.parseInt(pageCurrent);int start = size * (currentPage - 1);int totalSize = userService.getUserListSize(userName, departmentName);ArrayList<User> userList = userService.getUserList(userName, departmentName, start, size);if (userList.size() > 0) {return ToolUtil.listToJson(userList, size, currentPage, totalSize, "yyyy-MM-dd");}return null;}
