SpringMVC,Spring与Mybatis框架整合——ssm模板

1.创建如下结构的Maven项目

2.引入所需jar包的依赖坐标

3.数据库连接:db.properties

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username=vote(用户名)
jdbc.password=a（密码）
jdbc.initialSize=10
jdbc.minIdle=5
jdbc.maxTotal=100

日志配置文件:log4j2.xml

<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout pattern="%-5p %C{1} (%F:%L) - %m%n" />
        Console>

4.测试数据库连接:ConnTest.java

package com.yc.vote.test;

import static org.junit.Assert.*;

import java.sql.Connection;
import java.sql.SQLException;

import javax.sql.DataSource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring.xml")
public class ConnTest {

    @Autowired
    private DataSource dataSource;

    @Test
    public void testConn() {
        Connection con = null;
        try {
            con = dataSource.getConnection();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        assertNotNull(con);
    }
}
