目录
使用Spring集成Junit完成JdbcTemplate修改和删除
jdbc内容和配置解耦合
抽取配置文件中的jdbc代码，使用单独的一个配置文件将次分开
jdbc.properties下
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=123456applicationContext1.xml下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

<!-- 解耦合，抽取到配置文件中去-->
<!-- 加载外部的properties，需要使用context命名空间 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--数据源对象-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!-- jdbc模版对象-->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
</beans>修改一下数据
public class JdbcTemplateTest {
@Test
//测试Spring产生jdbcTemplate对象
public void test2() throws PropertyVetoException {
ApplicationContext app=new ClassPathXmlApplicationContext("applicationContext1.xml");
JdbcTemplate jdbcTemplate=app.getBean(JdbcTemplate.class);
int row = jdbcTemplate.update("insert into account value(?,?)", "ZH",66666);
System.out.println(row);
}
}返回测试，运行结果
数据库中变化：
使用Spring集成Junit完成JdbcTemplate修改和删除
在pom.xml需要导入两个包，spring-test包和Juit包
pom.xml
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.0.5.RELEASE</version>
</dependency>修改操作
新建一个类
package test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
//指定使用spring做为驱动内核进行测试
@RunWith(SpringJUnit4ClassRunner.class)
//配置文件的位置
@ContextConfiguration("classpath:applicationContext1.xml")
public class JdbcTemplateCRUDTest {
//被测试的用 @Autowired注入(测试谁就注入谁)
@Autowired
private JdbcTemplate jdbcTemplate;
@Test
public void testUpdate(){
int row = jdbcTemplate.update("update account set money=? where name=?", 222, "tom");
System.out.println(row);
}
}
Junit4.11版本导致错误
一开始我使用了junit4.11的版本

进程已结束，退出代码 -1
将其改为Junit4.12就可以正确执行了
运行结果
数据库中
删除的操作
@Test
public void testDelete(){
int row1 = jdbcTemplate.update("delete from account where name=?", "tom");
System.out.println(row1);
}运行结果
数据库中
