本文将介绍如何搭建ssm项目框架
- 加入依赖
- 编写配置
- 链接数据库
- 编写测试类
- 项目结构图
加入依赖pom.xml

使用阿里巴巴数据源配置数据库jdbc.properties
url:jdbc:mysql://172.7.52.231:3306/first_ssm?useUnicode=true&characterEncoding=utf8
driverClassName:com.mysql.jdbc.Driver
username:root
password:123456
#------------------------------------------------------------------------------------------
#配置扩展插件 监控统计用filters:stat 日志用filters:log4j 防御sql注入用filters:wall
filters:stat
#最大连接池数量 初始化建立物理连接的个数 获取连接时最长的等待时间 最小连接池数量 maxIdle已经弃用
maxActive:20
initialSize:1
maxWait:60000
minIdle:10
maxIdle:15
#有两个含义 1.Destroy 线程会检测连接的时间 2.testWhileIdle的判断依据
timeBetweenEvictionRunsMillis:60000
#Destory线程中如果检测到当前连接的最后活跃时间和当前时间的差值大于minEvictableIdleTimeMillis，则关闭当前连接
minEvictableIdleTimeMillis:300000
#用来检测连接是否的sql，要求是一个查询语句。在mysql中通常设置为SELECT 'X'
validationQuery:SELECT 'x'
#申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery连接是否有效
testWhileIdle:true
#申请连接时执行validationQuery检测连接是否有效 这个配置会降低性能
testOnBorrow:false
#归还连接时执行validationQuery检测连接是否有效 这个配置会降低性能
testOnReturn:false
#要启用PSCache，必须配置大于0，当大于0时，poolPreparedStatements自动触发修改为true
maxOpenPreparedStatements:20
#对于建立连接超过removeAbandonedTimeout的连接强制关闭
removeAbandoned:true
#指定连接建立多长就被强制关闭
removeAbandonedTimeout:1800
#指定发生removeabandoned时，是否记录当前线程的堆栈信息到日志中
logAbandoned:true
编写配置文件
spring-mybatis.xml
spring-web.xml
spring-service.xml
Configuration.xml
编写junit单元测试类
import com.aliyuncs.exceptions.ClientException;
import com.ambow.first.dao.TypeMapper;
import com.ambow.first.util.HttpUtils;
import com.ambow.first.util.Send;
import org.apache.http.HttpResponse;
import org.apache.http.util.EntityUtils;
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;
import java.util.HashMap;
import java.util.Map;
// SpringJUnit
@RunWith(SpringJUnit4ClassRunner.class)
// 加入配置
@ContextConfiguration({"/spring-mybatis.xml", "/spring-service.xml"})
public class Test {
@Autowired
private TypeMapper typeMapper;
@org.junit.Test
public void testType() {
System.out.println(typeMapper.queryAll().toString());
}
}
junit运行结果如下
