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=123456

applicationContext1.xml下


<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="

    bean>
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

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);
 
    }
}

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>junitgroupId>
            <artifactId>junitartifactId>
            <version>4.12version>
        dependency>

            <groupId>org.springframeworkgroupId>
            <artifactId>spring-testartifactId>
            <version>5.0.5.RELEASEversion>
        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

将其改为Junit4.12就可以正确执行了

    public  void testDelete(){
        int row1 = jdbcTemplate.update("delete from account where name=?", "tom");
        System.out.println(row1);
