spring-mybatis项目搭建（支持多数据源）

一、目录结构图

2、配置文件内容

db.properties：

#oracle public 
oracle.driverClass=oracle.jdbc.driver.OracleDriver
oracle.maxActive=14
oracle.initialSize=1
oracle.maxWait=120
oracle.maxIdle=14
oracle.minIdle=1
oracle.removeAbandoned=true
oracle.removeAbandonedTimeout=180
oracle.timeBetweenEvictionRunsMillis=60000
oracle.minEvictableIdleTimeMillis=1800000
oracle.connectionProperties=bigStringTryClob=true;clientEncoding=UTF-8;defaultRowPrefetch=50;serverEncoding=UTF-8

#oracle DB  注：oracle和mysql只是driverClass不一样，其他配置相同
oracle.jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:ORCL
oracle.jdbc.username=crh_snp
oracle.jdbc.passpword=cairenhui

freemarker.properties:

#freemarker settings
tag_syntax=auto_detect
template_update_delay=2
default_encoding=UTF-8
output_encoding=UTF-8
locale=zh_CN
date_format=yyyy-MM-dd
time_format=HH:mm:ss
datetime_format=yyyy-MM-dd HH:mm:ss

3、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
    
    <welcome-file-list>
        <welcome-file>page/index.html</welcome-file>
        <welcome-file>page/index.htm</welcome-file>
        <welcome-file>page/index.jsp</welcome-file>
    </welcome-file-list>
