spring的junit测试编写
package com.zl.mapper;
import com.zl.entity.Users;
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.List;
@RunWith(SpringJUnit4ClassRunner.class)

@org.junit.Test
public void myTest(){
List<Users> users = usersMapper.queryUsersAll();
for (Users user : users) {
System.out.println(user);
}
}
}
注意:
- 当使用lombok的时候,如果IDEA没有安装lombok插件就会报错
