 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

 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

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

      
            junit
            junit
            4.12
        
        
            org.springframework
            spring-test
            5.0.5.RELEASE
        

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
