}

public void setUserName(String userName) {

}

@Override
public String toString() {
return "MybatisUser [userName=" + userName + "]";
}

}

TestMybatisUserName.class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring-context.xml", "classpath:spring-mybatis.xml"})
public class TestMybatisUserName {

@Resource
private MybatisUser mybatisUser = null;

@Test
public void test() {
System.out.println("userName:"+mybatisUser.getUserName());
}

}

验证结果：

原因：

是因为属性冲突，配置文件里的username换成其他的名字, 如jdbc.username

username在windows下默认取值为电脑的账号，一般电脑账号为administrator，如果你的电脑账号是自己设置的那就为你设置的账号，数据库连接时数据库中没有administrator用户或者跟你电脑账号一样名字的用户，就会报错，一般为了避免和Windows基本配置冲突，数据库连接名常常写的较长如{jdbc.username}这样就可以唯一识别用户名而不会和Windows冲突。
