引入依赖

java 复制代码

<!--下面两个是测试相关的jar包-->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.1.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.13</version>
    <scope>test</scope>
</dependency>

测试类写法一：

java 复制代码

import com.imooc.spring.jdbc.entity.Employee;
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(locations = "classpath:applicationContext.xml")
public class EmployeeDaoTest {

    @Autowired
    private EmployeeDao employeeDao;

    @Test
    public void findById() {
        Employee employee = employeeDao.findById(3308);
        System.out.println(employee);
    }
}

测试类写法二：

java 复制代码

import com.imooc.spring.jdbc.entity.Employee;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class EmployeeDaoTest {
    @Test
    public void findById() {
        ApplicationContext context =
                new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        EmployeeDao employeeDao = context.getBean("employeeDao", EmployeeDao.class);
        Employee employee = employeeDao.findById(3308);
        System.out.println(employee);
    }
}
